Spring sowing eggplant late management

First, reasonable colonization

1. Adding base fertilizer to the whole land

After the crops are harvested in the solar greenhouse, the weeds should be removed in time, and the weeds should be deepened. The farmer's fertilizer should be 5000-6000 kg, and the superphosphate should be 15-20 kg. The base fertilizer is applied in 2/3, and 1/3 is concentrated in the planting ditch. The ditch is 55 cm apart and the ditch is 15-18 cm deep. 2. Colonization method and planting density

The density depends on the variety. If the width is narrow (80+50) 130 cm, the plant spacing is 40-60 cm, and the planting range is 1500-2500. Among them, the early-maturing garden eggplant (such as the fast garden eggplant) is dense and high. Eggplants (such as orchid and long eggplant) are in the middle, and large plant varieties (such as Jifeng 3) are relatively thin and cannot be too dense. Watering the seedlings, digging the nest, planting the water, filling the soil and sealing the nest. The soil is still dry and needs to be watered in the small ditch. Then cover the mulch and fill the straw with a large ditch. Second, the management of slow seedling period

After planting, it is necessary to carry out timely cultivating. Generally, the seedling period is carried out 2-3 times. The cultivating should be "early, diligent and deep" to increase the ground temperature and promote rooting and slow seedling. The temperature in the daytime is 30°C-35°C, in order to increase the ground temperature and reach 20-15°C at night. If the temperature is too high and the humidity is high, the air can be ventilated for a short time during the day.

Third, the results of the previous management

After the eggplant is slowed down, the room temperature should be lowered, and the temperature should be extended by 20-30 °C to avoid the high temperature above 35 °C. In the morning, the temperature reached 25 °C and began to release the wind. During the growth stage of the eggplant, it is timely to release the wind, cool down and damp, and ventilation can increase the light. The temperature during the day is maintained at 20-30 °C, the nighttime temperature is 16-17 °C in the middle of the night, and the average temperature in the middle of the night is 13-10 °C. The average temperature is above 20 °C. In the early stage, the water control seedlings and the middle tillage are the mainstays. When the eggplant begins to expand and the peel is bright and lustrous, the seedlings can be finished, watering and topdressing can be carried out to promote the rapid expansion of the fruit, and 10-15 kg of ammonium sulfate per acre or 1000 kg of feces can be used, according to the lyrics before harvesting the eggplant. Watering 1-2 times, after irrigating.
