Vegetable growth management management to keep up with
At present, summer vegetables enter the peak period of harvest, which is the peak season for harvesting and listing; greenhouse vegetables in the greenhouse enter the flowering period, and the open-cropped vegetables begin to harvest, but it is also a high-risk period for the protection of vegetable pests and diseases. The main farming management of vegetable fields cannot be relaxed.
Facility vegetable management needs to be fine
At this time, tomatoes, cucumbers, eggplants, sweet peppers, radishes, cabbage and other crops grown in the greenhouse have been harvested and matured. At this time, the vegetative growth and reproductive growth of the crops are carried out at the same time, which is a critical period requiring water and fertilizer, and it is particularly important to strengthen the field management.
Suitable growth environment
Although the current temperature is also high, it varies greatly. It is necessary to adjust the temperature and air humidity suitable for growth and development according to the external climate change and different crops. The physiological activity of cucumber is different from that of tomato and eggplant. Four-stage temperature regulation should be adopted. Cold-tolerant vegetables such as leaves and rhizomes should be kept in the air to avoid excessive night temperatures. Tomatoes, eggplants and other crops are kept at 40% to 50%; melon crops such as sweet peppers and cucumbers are 60% to 80%.
Strengthen watering and topdressing
According to the weather conditions, plant growth and soil conditions, watering and topdressing should be carried out. The topdressing should promote the integration of water and fertilizer technology. It is advisable to apply the instant fertilizer with reasonable nutrition and reasonable ratio with drip irrigation. To water small water, the amount of water per acre is 8 to 10 cubic meters, to avoid flooding. 20 bags of carbon dioxide gas fertilizer per acre to increase indoor carbon dioxide concentration, improve photosynthesis efficiency, play a role in increasing production and improving quality.
Do a good job in plant management and fruit management
Timely management of hanging vines, vines, lofting, pruning and snoring, cucumbers and tomatoes use the method of continuous desolate to prolong the results of the plants, and timely remove the lower yellow leaves, old leaves and diseased leaves; tomato in the first When the ear fruit grows to the green ripening stage, the lower leaves are destroyed, and the dark green leaves of the lower part of the cucumber are also destroyed in time to prevent the infection of downy mildew due to poor ventilation.
It is necessary to strengthen the auxiliary pollination and thinning and thinning; tomato and eggplant adopt natural pollination method to maintain the flavor and quality. The method of pollination can be used to assist pollination, or 2 boxes of bumblebee can be used to assist pollination. Tomatoes should be sprayed with an oscillating pollinator or conditioner when each flower is opened for 3 to 4 flowers per flower. If the flowers are sprayed when 1 or 2 flowers are opened, the fruit will only be 1-2 and affect the yield. . Remove excess flowers and fruits early. Cucumber does not need artificial aided pollination to form a melon. It is forbidden to use hormones to promote the expansion of young melon.
Fruit harvested in time after ripening
Timely harvesting of mature fruit not only increases the rate of the commodity, but also prevents the fruit from falling and affecting the plant's continued outcome. It is advisable to harvest it every morning.
Open field vegetables
When planting cucumbers, tomatoes, eggplants, peppers, pumpkins, etc. in open field, it is necessary to apply organic fertilizer as base fertilizer, apply 4000 kg of decomposed fine-grained high-quality organic fertilizer per mu, or 3000 kg of bio-organic fertilizer, of which two-thirds are even before the cultivated land. Laying, one third of the sputum is applied near the root of the crop. It is necessary to finely level the ground, to achieve leveling, flattening, straightness, and no shovel; to refine the seedlings 5 ​​to 7 days before planting to enhance the adaptability of the seedlings to the post-planting environment; The depth is the same, in which tomato and eggplant should be deeply planted, covering more than 2 to 3 cm above the nursery; cucumber, pumpkin, melon and other melon crops should be planted shallowly, covering soil and nursery. The management of fertilizer and water after planting should keep up. The management of vegetable seedlings will reduce the disease during the growth period and lay a good foundation for high yield and stable production.
