1. Adding base fertilizer to soil preparation
After harvesting the crops in front of the solar greenhouse, weeds shall be removed in time, deep-turned and flattened, 5000-6000 kilograms of Mushi farmyard fertilizer, and 15-20 kilograms of superphosphate, and then soiled and mixed evenly. 2/3 of the base fertilizer is applied, and 1/3 is concentrated in the planting trench. The trench is 55 cm apart and the trench is 15-18 cm deep. 2, planting methods and planting density
The density depends on the species. If the width is (80+50) 130 cm, the spacing between the plants is 40-60 cm, and the cultivars are between 1500 and 2500. Among them, the early-maturing garden eggplant (such as the fast garden eggplant) is denser and the sorghum grows longer. The eggplant (eg, Lanzhu long eggplant) is centered, and the large plant variety (eg, Jifeng No. 3) is relatively thin and not too dense. Watering seedlings, digging nests and colonization, drip fossa water, fill the nest. Dry soils also need to be watered in small trenches. Then cover the mulch and furrow the straw. Second, the management of seedlings
After planting, timely cultivating should be carried out in a timely manner. Generally, the cultivating period should be carried out 2-3 times. The cultivator should be “early, diligent, and deep†to increase the ground temperature and promote the rooting of the seedlings. The daytime temperature is 30°C-35°C to increase the ground temperature and reach 20-15°C at night. If the temperature is too high and humidity is high, ventilation can be performed for a short period of time during the day.
Third, the results of the early management
After the eggplant is slowed, reduce the room temperature and try to prolong the temperature of 20-30°C to avoid high temperatures above 35°C. In the morning, the temperature reached 25°C and began to release air. In the growth stage of the phytophagous, timely release of air, cooling and dehumidification, ventilation can increase the light. During the day, the temperature is maintained at 20-30°C, nighttime temperature is 16-17°C in the middle of the night, and 13-10°C is in the middle of the night. The average ground temperature is above 20°C. The results are mainly controlled by water seedlings and cultivators. When the door eggplant starts to enlarge and the peel is bright and shiny, the seedlings can be finished, watering and topdressing, and the rapid expansion of the fruit can be promoted. The ammonium sulfate is 10-15 kg per mu or 1,000 kg of fecal material is dilute. Watering 1-2 times, cultivating after watering.
