Carefully prepare the ground, and apply organic fertilizer to the cucumber seedlings. The rhizome has a large water content, is brittle and easy to fold. No big waste and rich in organic matter. When ploughing and raking, you should apply rotten chicken manure and cake fertilizer in layers, 5000 kg of chicken manure per acre and 2000 kg of cake fertilizer.
Soil sterilization, the mulching index in the mulching shed is high, the soil bacteria content is large, the soil disinfection treatment should be done well. Use 1.5 kg of fulvic salt or 0.75 kg of carbendazim wettable powder per acre of land, mix 5-7 kg of fine sand or fine soil to evenly spread the buns, and then rake the ridges. When ridged, proceed in wide and narrow rows, with a width of 80 cm and a narrow line of 70 cm. The ridge is 15-18 cm high, and the ridge is required to be as straight as a line. Dig a watering ditch 30 cm wide and 10 cm deep between the ridges and fill them. Mulch should be covered with mulch to increase ground temperature.
Plant in time to prevent plant diseases and insect pests. Plant a row on each side of the ditch on the ridge, with a row spacing of 60 cm, a plant spacing of 30 cm, and 2700 cucumbers per acre. 75% chlorothalonil was sterilized once on the seedbed before emergence. After planting in the whole shed, fumigate the shed with 20% Subai fumigant and aphis fumigant fumigant once to prevent the occurrence of pests.
Careful management, when the water supply and fertilizer are reasonable and when the seedlings grow to about 30 cm, they should be lifted in time to remove the seeds, so as to facilitate the rapid growth of ventilation and light transmission. Watering according to the spitting condition and leaf phase of the growth point of cucumber head in the morning. If there is no dew in the morning or noon at normal temperature at the growth point, the leaf surface will wither and should be watered under the film in time. At the same time, after the female melons have given flowers, 5 kg of urea and 5-7 kg of potassium sulfate compound fertilizer are added per acre of land in order to increase the yield of the melon. The temperature of cucumber field in spring should be controlled at 25 ℃ ～ 28 ℃ during the day and at about 15 ℃ at night. Pay attention to ventilation and dehumidification to prevent high temperature, and maintain the temperature difference between day and night.
