What is the planting management technology of cucumber in greenhouse?

First, carefully prepare the soil and apply organic fertilizer respectively. The root system of cucumber seedlings is brittle and easy to break, which is not only afraid of flooding but also not drought-resistant. Therefore, when preparing soil, the ground should be flat and slightly inclined to one side, which is beneficial to irrigation and drainage, and the soil is rich in organic matter. When plowing and raking, fully decomposed chicken manure and cake fertilizer are applied in layers, with 5000 kg of chicken manure and 2000 kg of cake fertilizer per mu.

Second, soil disinfection, ridging and plastic film mulching greenhouse has a high multiple cropping index and a large amount of bacteria in the soil, so it is necessary to disinfect the soil. Each acre of land can be evenly sprinkled with fulvate 1.5 kg or carbendazim wettable powder 0.75 kg mixed with 5-7 kg of fine sand or fine soil, and then finely raked and ridged. When ridging, it is carried out in narrow rows, with a width of 80 cm and a width of 70 cm. Ridge height 15 ~ 18 cm, and the ridge should be straight as a line. Dig a watering ditch with a width of 30cm and a depth of10cm between ridges, and inject water. The ridge should be covered with plastic film to raise the ground temperature.

Third, timely planting, pest control Mid-March is the best time to plant cucumbers in our province. Plant a row on both sides of the drainage ditch on the ridge, with a row spacing of 60 cm and a plant spacing of 30 cm, and plant 2700 cucumbers per mu. Disinfect the seedbed with 75% chlorothalonil once before emergence. After planting in the whole shed, use 20% essence fumigant and aphid fumigant to buckle the shed for fumigation once to prevent pests and diseases.

Fourth, careful management, reasonable water supply and fertilization When the seedlings grow to about 30 cm, they should be hoisted in time to facilitate their rapid growth. In the morning, water the cucumber head according to the watering situation of the growing point and the leaf stage. If there is no dew at the growing point in the morning or the leaves wilt slightly at noon, water them immediately under the film. At the same time, after the female melon withers, 5 kg of urea and 5 ~ 7 kg of potassium sulfate compound fertilizer are applied per mu to facilitate the expansion of melon and achieve high yield. In spring, the ground temperature of cucumber is controlled at 25 ~ 28℃ during the day and 65438 05℃ at night. Pay attention to ventilation and dehumidification, prevent high temperature and keep the temperature difference between day and night. For more planting techniques, please visit Baidu Wang Di.
