Clever growth of cucumbers in summer
The fine soil preparation site can select rows, dry and pourable, and breathable fields. It can be used to cultivate and turn over fine land, combined with 5,000 kg of organic manure, 50 kg of compound fertilizer, and 5 kg of multi-element boron fertilizer. , 1.2 meters wide, sowing after 3 days of exposure.
The cucumber varieties suitable for sowing should be selected from varieties that are resistant to high temperature, light, pods, and diseases. Such as Jinchun No. 4, Jinyan No. 4, Ludi No. 2, Xiafeng No. 1, and so on, live broadcast around May 20, sowing the seeds before drying 2 to 3 hours, put the seeds into warm water of 60°C, stirring constantly. After the water temperature dropped to 30°C and soaked for 4 hours, remove and put it in a wet gauze and place it at a temperature of 30°C to 35°C, and half of the seeds could be sown. For each species of 2 rows, the distance is 20 centimeters, 3 seeds per hole, about 5000 points per mu, and 90 centimeters wide film after sowing.
In the field management, the melon seedlings immediately ruptured when the top membrane was uncovered. After the membrane was exposed to dry weather, it was necessary to water the trees one by one at night. Qimiao 7 days after the seedlings, leaving a healthy seedlings per hole, and poured a water, after the first cultivator, more cucumber than spring cucumber cultivator to shallow, 4 to 5 cm deep can be. Timely removal of leaf tendrils and lower old leaves, diseased leaves, etc. The weeds were cleared at the early flowering stage and the second cultivator was harvested before harvesting the root melons, 2 cm deep. Throughout the summer, the cucumber grows rapidly and grows quickly. In addition to applying base fertilizer, it is necessary to top-dress fertilizers and early-dressing fertilizers, especially to increase phosphorus and potassium fertilizers. After entering the melon period, over-summer cucumber grows vigorously, watering and rainfall are more, soil nutrient is easy to lose, so it should be more fertilizer, diligent watering, watering should be in the evening or morning, should not be watered at noon. In high-temperature and dry weather, watering is conducted once every 1 to 2 days, and 20 kg of urea or high-nitrogen compound fertilizer is applied to the trapped water. In case of rain or heavy rain, it is necessary to drain water and prevent flooding. After the hot rain, the well water must be cooled in time. In order to prolong the melon period and increase the yield, 100 kg of potassium dihydrogen phosphate and 50 kg of water per acre can be used for foliar spraying, and sprayed once every 3 to 5 days and sprayed three times.
The pest control seed disinfection can be used 3000 times 96% Tianda hymexazol liquid plus a new high-fat membrane 800 times liquid seed dressing, with seedlings enemy, enemy cough spray to prevent guai seedlings damping-off disease; early flowering time with 25% 代森Manganese 1500 times liquid or 25% fast killing emulsion 1000 times spray to prevent downy mildew, soft rot and other diseases; Shenggua period choose fast killing, rapid killing small, enemy killing, imidacloprid and other low residual agent control Insect pests, spraying 75% chlorothalonil or 72% DuPont Kelu wettable powder or agricultural streptomycin to control downy mildew, keratopathies, etc., spread more than 96% copper sulfate 3 kg per mu before watering to prevent and control diseases, Huang Shougua 90% trichlorfon can be used 1500 ~ 2000 times liquid spray, or use phoxim 1000 ~ 1500 times liquid irrigation root.
The timely recovery of high summer temperatures, rapid plant growth, rapid fruit development, generally 50 to 60 days after sowing can be harvested. Over-summer cucumbers have a high rate of results and can be harvested several times over multiple harvests. Harvesting should be done early to collect ground and harvest, so as to avoid falling seedlings. Generally, harvesting is done every other day. Harvesting can be harvested every day to ensure that the melon strips are fresh and melons秧 vigorous growth.
Puffed corn flour is a type of flour made from corn that has been puffed or expanded through a process of heat and pressure. The process involves heating the corn kernels until they become soft and moist, and then rapidly releasing the pressure, causing the kernels to puff up. The puffed corn is then ground into a fine flour that can be used in a variety of recipes. Puffed corn flour is often used as a gluten-free alternative to wheat flour in baking and cooking, and is also used in snack foods such as popcorn and corn chips. It is high in fiber and protein, and has a light, airy texture that makes it ideal for use in baked goods.
