The temperature is suitable for lighting small enough vegetables for good timing

Xiaomang is the eighth solar term in the 24th lunar calendar, on May 21 of this year's Gregorian calendar. From the beginning of small-scale solar terms, the seeds of summer crops such as northern barley and winter wheat have turned to be full, but they have not yet matured. Small and full solar season temperature is suitable, light is sufficient, climatic conditions are suitable for the growth of a variety of vegetable crops, is the best time for the flowering fruits and vegetables of various kinds of thermophilic vegetables grown in protected areas and open fields, and is also suitable for the growth of leafy vegetables. A variety of vegetable diseases and insect pests have high incidence. The main agricultural activities of the Xiaomanjie Gas Field are:

Greenhouse harvest time

At this time, the tomatoes, cucumbers, eggplants, peppers, and pumpkins grown in the solar greenhouse are harvested at a time of harvest. The cucumbers, zucchini, and eggplants grown in plastic greenhouses have also been harvested. This period is the most vigorous period of vegetative and reproductive growth of most vegetable crops, and it is also a critical period for the production of crops. Therefore, it is very important to strengthen field management.

◆ Adjust the appropriate temperature and humidity At this time, the outside temperature is high, and the ventilation and air exchange in the studio should be strengthened. In particular, it is necessary to promptly release the air in rainy days and rainy days, and reduce the temperature and humidity in the booth. Tolerant temperature crops such as tomatoes and cucumbers are suitable for temperatures ranging from 23°C to 30°C in sunny days, 3°C to 5°C in cloudy days, 20°C to 23°C in night, and 15°C to 20°C in night; lettuce, Celery and other leafy and rhizome like cool crops, suitable temperature during the day at 20 °C -22 °C, at night in the 10 °C -12 °C, in particular, should avoid excessive nighttime temperature and increase respiration to increase nutrient consumption. If celery and other cool vegetables are overheated during the day and the light is too strong, the fiber of vegetable products will increase, resulting in poor quality and poor taste. Different indoor air humidity should be adjusted according to different crops. The tomato, eggplant and other crops are kept at 40%-50%; sweet peppers and cucumbers and other melon crops are kept at 60%-80%; sweet peppers should spray water between the rows at noon on sunny days to increase air humidity.

◆ Scientific top dressing and watering Topdressing according to weather conditions, plant growth and soil conditions to meet growth needs. To water the ground with small water, each time the amount of water per acre of 5 -10 square, to avoid flood irrigation, to prevent excessive soil moisture and affect the root growth of normal absorption of water, nutrients. Top dressing should vigorously promote the integration of water and fertilizer technology. It is advisable to use fast-dissolving fertilizer such as “Christmas tree” with reasonable nutrient content and drip irrigation, and to apply high potassium with a nitrogen, phosphorus and potassium content of 16:8:34 during the fruit expansion period. "Christmas tree" 5-8 kilograms per mu; can also be applied with water NPK full organic liquid fertilizer, in order to promote vegetative growth and reproductive growth balance, multi-residue commodity rate of high fruit.

â—† Plants can be hauled in a timely manner to hang vines, vines, loquats, pruning and smashing to remove the lower yellow leaves and old leaves. Greenhouse tomato leaves four ears of fruit, timely tipping; in the first ear fruit green ripening period (when whitening no longer grows) the lower leaves are knocked out. Cucumbers in time to prolong the elongation of the plant's melons, and the use of falling vines can promote the growth of the plants, timely destroying the lower dark green leaves to prevent infection of downy mildew due to poor ventilation. Tomato and cucumber are suitable for retaining 16 functional green leaves per plant in order to ensure the plant growth and the requirement for photosynthetic products with fruit enlargement.

â—† Fruit management should pay attention to assistant pollination and fruit thinning and fruit thinning; tomatoes and eggplants should maintain good flavor and quality, and natural pollination methods should be adopted. Oscillatory pollinator can be used to assist pollination, or 1-2 boxes of bumblebee pollination can be released per acre; if growth regulators such as "Fengcengjing No.2" are used to decorate or spray flowers, different concentrations should be prepared according to different room temperature. To prevent the formation of malformed fruits due to high concentrations. Tomatoes should be sprayed with oscillating pollinators or conditioners when they are open to 3-4 flowers per panicle. If the flowers are sprayed just after opening 1-2 flowers, it will cause only 1-2 fruits to affect the yield. Early sparse excess flowers and fruits. Cucumber does not need artificial auxiliary pollination can normally produce melon, and it is forbidden to use hormones and flowers to promote the growth of young melons and flowers do not fall.

â—† Harvesting in time in the best commodity period can not only increase the commodity rate, but also prevent fruit from falling and affecting the plant's continuing results. The late harvest of leafy vegetables will affect the quality, and the quality of the harvest will be the best in the early morning every day, which will increase the nutrient content, taste and flavor of the fruit. Cucumbers, sweet peppers, and eggplants are cut with scissors to prevent the plants from being torn when hand-picked and susceptible to disease. Take care when picking, avoid causing damage to the fruit and reduce product quality. If bamboo baskets or Vitex baskets are used, they should be covered with soft paper or agricultural film to prevent them from stinging; they must also be classified according to fruit size.

Open field harvesting to improve the quality of refurbishment

Tomatoes, eggplants and other eggplant fruits are in the fruiting period. The cucumbers have already been harvested, the plants are growing vigorously, and the amount of fertilizers required is gradually increasing. Watering, topdressing, cultivating and weeding, vine burping, and auxiliary pollination must be performed in time. management. Rapeseed, lettuce, garland chrysanthemum, radish and other fast-growing cabbage and cabbage, lettuce, cauliflower and other cabbage vegetables to the harvest period, in the best commodity period timely harvest and listing, to improve the quality of refurbishment, to maintain the quality of old Beijing vegetables tradition of. Watering and weeding in time.

Scallion planting

It is not appropriate to re-appropriate and apply sufficient organic manure to deep-seed the land and choose to grow and grow onion seedlings. When the planting is completed, the density is reasonable and the depth is consistent. The way of planting with open trenches is generally 90-100 cm and the spacing is 8 cm. . Timely planting water.

Greenhouse summer tomato seedlings

Adjust the suitable temperature, light, etc. of seedling sheds, timely watering and top dressing, and change the position so that they grow neatly and consistently. Ten days before planting, the front rakes are pulled and the stubborn leaves, rotten leaves and weeds are removed, transported to designated locations for harmless treatment such as high-temperature composting, and the farmland is ploughed thoroughly after sufficient organic manure, 10 days in advance. Do a good job, according to a distance of 1.5 meters to make a 20-centimeter-high stilts above the ground, sorghum width 80 cm, sulcus width 70 cm, two rows per planting.

Strengthen pest control

As the temperature increases and rainfall increases, the humidity in the shed increases, and the occurrence and damage of pests and diseases is gradually aggravated, especially for tomato gray mold and late blight; cucumber downy mildew, powdery mildew, bacterial keratoderma and other diseases and aphids, Whitefly, red spider, thrips, tea-yellow, cabbage-worm and other insect pests. It is necessary to install a solar trap lamp in every 100 mu area in vegetable fields. Based on physical control measures such as the installation of pest control nets, hanging traps, yellow plates and blue boards on the air outlets and doorways of the greenhouses, the investigation of the occurrence of pests and diseases should be conducted. The biological pesticides or low-toxicity, low-residue pesticides should be used in the best prevention and control period. , At the same time, ensure the safety interval after application, and then pick up the market later to ensure product safety.

Tomato oscillating pollinator using technology

Tomato cultivation in protected areas, due to natural forces and insects and other external factors have little effect, so the natural pollination rate decreased, resulting in reduced fruit set. In order to solve this problem, the Beijing Municipal Agricultural Technology Extension Station has introduced an oscillating pollinator from the Netherlands to improve the power supply, vibration frequency, handles, vibrations, etc., and obtained a utility model patent authorized by the State Intellectual Property Office.

â– Advantages of pollinator-assisted pollination

Promoting fruit setting in high humidity environment, forcing pollen to be dispersed and completing pollination, effectively improved the fruit set rate of tomato.

Improve single fruit quality and yield Tomatoes enlarge due to pollination, avoid empty fruit, improve the quality of fruit, and increase the overall yield.

By improving the commercial quality and quality of the fruit, the fruit is even and tidy, no deformed fruit, full fruit, rich juice, high sugar content, and better flavor. As the fruit setting rate has increased, more room has been chosen for fruit thinning to avoid the appearance of size and size.

High security Due to the fact that it is hardened by natural pollination, the resulting fruits are different from the flowers sprayed with conditioners. They belong to seeded fruits and are safe to produce and meet the requirements of organic food standards.

The provincial labor force pollination operation time per mu is only about 30 minutes, while the use of spray or flower decoration method takes 2-3 hours. At the same time, vegetable growers do not need to bend over to reduce labor intensity and save labor costs.

The prevention of gray mold pollinator can shake off the residual flowers of the tomato when it is shaken, thereby reducing the occurrence of infestation of the spent flowers by the gray mold and invading the tomato fruit.

â–  How to use

The oscillating pollinator is roughly divided into several parts: the battery, the handle and the oscillator. When the battery is used, the battery is firstly put on the body, and then the power cord is inserted into the corresponding position of the battery. At this time, the oscillator part starts to oscillate and the instrument starts to work. When more than two-thirds of the flowers in each spike inflorescence are open, an oscillatory pollinator can be used to assist pollination. Pollination should be selected from 8:00-10:00 am on sunny days. After the humidity in the greenhouse is reduced and the dew is gone, the oscillator probe can be left in contact with the tomato inflorescence stem for about 0.5 seconds. When the pollen volume is large, it can be seen with the naked eye. Pollen was scattered and assisted pollination was completed. In order to ensure the success rate of pollination, pollen-assisted pollination is used once every 1-2 days. Note that the efficiency of the room temperature is 15°C to 30°C. When the temperature is too high or too low, effective measures should be taken to adjust the suitable room temperature.
