Detailed Explanation of Key Techniques for Growing Eggplant in a Greenhouse

When growing eggplant in a greenhouse, it is generally best to choose early-maturing varieties with long-shaped fruit, then soak the seeds in warm water for five or six hours, take them out, and put them in gauze to let them sprout. After they sprout, sow them into a seedling tray. After the seedlings emerge, transplant the seedlings into the soil at a row and plant spacing of 15*10cm, then water lightly, apply some compound fertilizer, and carry out basic management tasks such as pest and disease control, and they will grow healthily.

Greenhouse Eggplant Planting and Management Techniques

1. Land preparation

When using a greenhouse to grow eggplant, the first thing we need to do is choose a suitable planting site. Greenhouse planting sites generally need to be relatively flat, so that greenhouse construction and later planting management are convenient. After choosing the planting site, the land should be improved and prepared according to the terrain of the planting site and the growth habits of eggplant. Level the planting site, break up the soil clods, then apply sufficient fertilizer, open good drainage ditches, and make flat beds about two meters wide.

2. Greenhouse construction

Generally, one greenhouse is built over two flat beds, which is about four meters. Next, the height of the greenhouse should be at least about two meters, so that field management is convenient. If the greenhouse is too short, then later field operations will be very tiring, but if it is too tall, then it is also easily affected by external conditions, and at the same time it increases the cost of greenhouse construction.

3. Pruning branches and removing leaves

After eggplant is planted, in order to promote the growth of eggplant and encourage eggplant to enter the flowering and fruiting stage as early as possible, we can appropriately organize the branches and leaves. Generally, when eggplant has grown to about thirty centimeters, remove the terminal bud of the eggplant seedling to promote the growth of side branches. When the eggplant plant takes shape, we need to suppress the growth of the plant and promote flowering, so the terminal buds of the side branches should be removed. In order to maintain the permeability of the plant, branches and leaves that are too dense need to be removed, avoiding poor light and ventilation.

4. Reasonable temperature control

The most important point when growing eggplant in a greenhouse is temperature management, because temperature has a very large impact on eggplant pollination. In order to increase the success rate of eggplant pollination, temperature management needs to be carried out reasonably. During greenhouse cultivation, if the temperature is too low or too high, it will affect eggplant pollination, and symptoms such as flower drop, fruit drop, and deformed fruit are likely to occur. So we can appropriately spray some hormones to prevent flower and fruit drop, such as 2,4-D and fruit-setting hormone.

The above is the relevant introduction to greenhouse eggplant planting techniques. We hope it is helpful to everyone.
