In the early stage, the cucumber cultivation technique was 1, and the varieties with good disease resistance and good harvest should be selected, such as: JD.COM Baitiao Duanyang, Xintai Mici, etc.
2. In the middle and late February, choose greenhouse or sunshine bed to raise seedlings. Firstly, put the seedling pot filled with culture soil (cooked soil without melon vegetables and compost organic fertilizer in the ratio of 4: 1) into the greenhouse or greenhouse, pour water through it, and spray 800 times of 50% triadimefon granules for disinfection and sterilization at seedling stage; Secondly, soak the seeds in boiling water at 55℃ for 2-4h, then wrap them with a wet towel and place them at 28-30℃ to promote the growth of teeth. Rinse them with 1 time warm boiling water for 4-6h, and the seeds can germinate after 24 hours. After all the seeds germinate, put them in a cup seedling, 2 in each pot, then cover with the original culture of 1.50cm, and they will sprout in 6-8 days. Pay attention to controlling humidity and preventing diseases, such as verticillium wilt, cutworms and grubs.
3. Ploughing and fertilization should choose land with flat terrain, high fertilizer efficiency and convenient irrigation, and immediately ditch, water and subsoil when the soil layer thaws in early spring and March; Combining ploughing and one-time application of sufficient fertilizer, 5000 kilograms of high-quality organic fertilizer, 20 kilograms of urea and 50 kilograms of phosphorus and potassium fertilizer are applied per mu.
4. Planting with ridging and film mulching width, that is, ridging and film mulching width 17cm, agricultural film mulching width 1 cm, with width of 70cm, width of 50cm and ridge spacing width of 50cm.
5. Set up a vegetable shed as soon as possible in the middle and late March, with a span of 4.80 ~ 6 meters and a relative height of 1.70 ~ 2 meters. Use small bamboo poles as arch poles to build cast-in-place beams to ensure that the arch poles are tied horizontally and vertically to resist the sweeping of spring sandstorms; Then fasten the greenhouse film to quickly increase the soil temperature.
It is suitable for transplanting in early June and April, and can be transplanted when the soil temperature in the shed exceeds 65438 02℃. Rows of "D"-shaped holes are opened on the surface of the ridge, with the row spacing of 40 cm and the plant spacing of 50 cm. Trees are transplanted and planted, with 2200 plants per mu and the vine spacing of 20 cm, with 4000 plants per mu. After planting, water the roots once, and water 6000 plants per hole.
7. Field management strictly controls the temperature and humidity in the shed. The temperature should be controlled at 25 ~ 30℃ in broad daylight. When the temperature exceeds 35℃, the shed mouth should be opened immediately to water the flowers, and the watering mouth should be closed around 4 noon, and the temperature at night should not be lower than 16℃. The humidity is controlled at about 85% to reduce the occurrence of downy mildew, leaf blight and other problems. Drainage at seedling stage to promote roots, no watering; Water was poured every 7 ~ 10 days in high-yield period, and urea 10Kg was applied at each time. In the middle and late May, when the temperature rises and the frost period ends, all plastic films in the greenhouse can be removed, and bamboo poles can be disassembled and cultivated in the open field.
8. Harvesting root melons in time should be early to prevent seedlings from falling off. When the root melon grows to about 12 cm, it can be harvested every 2-3 days in the high-yield period in order to compete for the market in the morning.
The cultivation technique of the next corn is 1. It is appropriate to choose the mature hybrid Dan 4 with excellent varieties, and the sowing amount per mu is about 1.50 kg.
It is suitable for planting in the middle and late June, and cucumber can be planted before it grows to the middle and late June. The way is to break water on the ridge surface between the roots of two cucumber plants at10.33 cm, with 2 seeds per hole, 2 rows per ridge and 3,700 seedlings per mu.
3. Field management of bud stage of maize seedlings in three-leaf stage and five-leaf stage, selecting seedlings with average size; At the end of June, after the cucumber seedlings were pulled out, all the dead branches and leaves in the field were eliminated, and the fertilizer and water management methods of corn were improved. Irrigate and fertilize corn at jointing stage and cough stage in time, topdressing 20 kilograms of urea per mu, drilling holes with a depth of 10 ~ 10 cm in the root of corn, or irrigating with a fertilizer applicator, and sealing the holes with sand after fertilization. Corn from heading to booting stage can also be sprayed with 0. 10% ~ 0.20% sodium dihydrogen phosphate solution 1 ~ 2 times.
4. In the seedling stage of pest control, soil cultivation and weeding should be carried out for 2 ~ 3 times in time, or weeds in the field can be manually pulled out; It was found that if the scarab was injured by Myxomycetes from dairy cows in the second half of growth and development, it could be prevented by spraying 50% phoxim acetamiprid 1000 times solution and 20% pyrethroid acetamiprid 2000 times solution.
5. At the beginning of10, when the bracts turn yellow and the seeds harden, harvest the corn in time. Plow in autumn as soon as possible, plant plastic film wheat or change vegetables in the coming year.
