I. Careful soil preparation, organic fertilizer The roots and stems of cucumber seedlings have larger water content, which is brittle and easy to fold. They are not afraid of flooding or drought tolerance. Therefore, when leveling the ground, the ground should be leveled and slightly inclined to one side to facilitate irrigation and drainage. The soil is not sloppy and rich in organic matter. When cultivating the land, it is necessary to layer and apply the decomposed chicken manure and cake fertilizer, 5000 kg of chicken manure per mu and 2000 kg of cake fertilizer.
Second, the soil disinfection, the ridge-covered land mulch in the greenhouse has a high multi-replication index, the soil contains a large amount of bacteria, and the soil should be disinfected. For each acre, 1.5 kg of fulvic acid or 0.75 kg of carbendazim WP can be mixed with 5 to 7 kg of fine sand or fine soil to evenly spread the hoe, and then ridge the ridge. When ridges are carried out in width and width, the width is 80 cm and the narrow behavior is 70 cm. The ridge height is 15 to 18 cm, and the ridge is required to be straight. Dig a watering ditch 30 cm wide and 10 cm deep between the ridge and the ridge and fill the water. The ridge should be covered with a mulch to raise the ground temperature.
Third, timely planting, prevention of pests and diseases in mid-March is the best time to plant cucumbers in our province. Planting a row on both sides of the gully drainage ditch, the row spacing is 60 cm, the plant spacing is 30 cm, and 2700 cucumbers are planted per mu. Sterilize with 75% chlorothalonil on the seedbed before seedling. After the whole shed has been planted, use 20% speed hundred smoked fumigant and smouldering agent to fumigation once to prevent pests and diseases.
Fourth, careful management, reasonable water fertilizer until the melon grows to about 30 cm, it is necessary to hang the melon in time to facilitate its rapid growth of ventilation and light. According to the head water growth point of the cucumber in the morning spitting water and leaf phase watering, the growth point at the morning without dew or at noon normal temperature, the leaf surface is slightly wilting should be immediately subsurface watering. At the same time, after the melon flower is thanked, 5 kg of urea and 5 to 7 kg of potassium sulphate compound fertilizer are applied per mu to make high yields. The temperature of the cucumber ground in spring should be controlled at 25 to 28 °C during the day and at around 15 °C during the night. Pay attention to the ventilation and moisture to prevent high temperature, and maintain the temperature difference between day and night.
