Before the eggplant expands, it is necessary to properly control the water to prevent excessive watering, long white plants and falling flowers. Under suitable conditions, it takes about 18~25 days from flowering to fruit harvesting, and the first harvesting period of eggplant is in the middle and early May. During the fruit growth, the weather has turned warmer, and all the films can be uncovered during the day to let the plants fully see the light, but they should be covered at night. If the temperature is stable above 20℃ at night, you can stop covering it.
Prospering the weak and controlling the glory. The weak growth potential and insufficient nutrition of eggplant plants will aggravate the falling flowers and fruits; However, if the growth is too strong, it will cause a relative lack of nutrition, leading to falling flowers and fruits. Therefore, maintaining normal growth is the basic requirement to promote eggplant flowering and fruit setting. Therefore, for plants with weak growth, the growth should be enhanced by increasing fertilization water; Only by properly controlling fertilizer and water and promoting its normal growth can the fruit setting rate be improved.
Adopt close planting and pruning cultivation methods. When the flowers of "Simao Bean" appear buds, leave two leaves above the flowers of "Simao Bean" to pick the core, and wipe off the branches on the main stem and the first and second branches. In this way, there are only seven fruits left on each plant, namely eggplant, eggplant and four females and a half. When the planting density is low, leaves can be left above the flower buds of "Bamianfeng", and each plant can leave more than 10.
In the fruiting period, pick the kernel and topdressing in time. Generally, the fruit-setting rule of eggplant with seeds increases with the branches of plants, and basically there is one fruit-setting in each branch. In planting management, we should make full use of this feature, pick the seeds in time after planting, promote its rapid branching, increase the fruiting parts and improve the fruit setting rate. Eggplants need more fertilizer at the fruiting stage. Top dressing can be applied once after eggplant harvest and once after eggplant harvest, with 0.5~ 1 kg ammonium sulfate per standard, or 40~50 kg decomposed human manure, and watered in time after top dressing.
About 20 days after flowering, when the fruit is fully mature, there is no white part near the sepals, which indicates that the fruit is fully mature and can be harvested before the surface luster of the fruit fades. Because the flowering and fruiting habits of eggplant are batch flowering and batch fruiting, harvesting is also carried out in batches. Eggplant fruit is picked in the open field after 2-3 times, so it can create better economic benefits.
