Eggplant hi fat, avoid continuous production. The base fertilizer should be fully applied. Each 667m2 can be applied to a decomposed stack of manure fertilizer of 6 000 to 7,000 kg, 40 kg of phosphate fertilizer, and 100 kg of vegetation ash. According to a row of 55 cm, the gap between the north and the south is ditched, the depth of the ditch is 6 cm, and the distance between the rows is 38-40 cm. Water is placed on the seedlings after the cover is placed, and the ridges are raised again the next day. There are also large and small rows, with 60 cm large rows and 50 cm small rows. After the ridges are formed, they are covered with thin films on small rows, and 2,600 to 2,700 plants are planted on 667 square meters. Adding a small arch shed at night to keep warm, maintain 25 ~ 30 °C during the day, 15 ~ 20 °C at night, at noon can be properly ventilated. After 2 months, the amount of ventilation can be gradually increased depending on the weather conditions, but it must be maintained at a temperature of 15°C or more at night, otherwise flowering eggplants will form and fall. Until the late mid-May, when the outside temperature exceeds 15°C, it can stay up late. During the low temperature period, the film should be cleaned frequently so as to absorb as much light as possible. It is advisable to hung aluminized film reflector on the north side of the greenhouse to increase the temperature. Moisture should be properly controlled. Except for 3 to 4 days after planting, choose a sunny day to pour the seedlings, generally do not water, and when the size of the door grows to the size of the walnuts, begin submerged irrigation under the membrane, and the soil temperature in the middle and late March reaches 18 Above °C, water can be watered together with dark ditch, and attention should be paid to ventilation and ventilation. After 5 to 6 days of warm weather, it will keep the soil moist. After starting watering, fertilizer can be top-dressed once every half month, applying 20 kg of ammonium nitrate per 667 square meters. In the greenhouse cultivation, in order to improve the ventilation and light transmission conditions, it is feasible to double dry pruning. After the formation of the eggplant, cut out two outward lateral branches, it becomes a double dry in both directions. Afterwards, all the lateral branches are destroyed, generally in the knot. After 7 eggplant topping.
