Detailed Explanation of Key Technical Points for Eggplant Cultivation and Management in Greenhouses
Growing eggplants in greenhouses is a very common practice, so do you know how its management methods differ from open-field cultivation and management? How is the management work for greenhouse eggplant cultivation carried out? How much do you know about growing eggplants in greenhouses? Today let us take a look at the greenhouse eggplant cultivation and management techniques we have compiled for you.
1. Land preparation
When using greenhouses to grow eggplants, the first thing we need to do is choose a suitable planting site. Greenhouse planting sites generally need to be relatively flat, which makes greenhouse construction and later planting management convenient. After choosing the planting site, land improvement and preparation should be carried out based on the terrain of the planting site and the growth habits of eggplants, leveling the planting site, breaking up soil clods finely, then applying sufficient fertilizer, digging drainage ditches, and making flat beds about two meters wide.
2. Greenhouse construction
After preparing the land, we need to build the greenhouse, generally building one greenhouse over two flat beds, which is about four meters. Next, the height of the greenhouse should be at least about two meters, which makes field management convenient. If the greenhouse is too short, then later field operations will be very laborious, but if it is too tall, it is also easily affected by external conditions, and at the same time it increases the cost input for greenhouse construction.
3. Pruning branches and removing leaves
After eggplants are planted, in order to promote the growth of eggplants and encourage them to enter the flowering and fruiting stages as early as possible, we can appropriately organize the branches and leaves. Generally, when the eggplants have grown to about thirty centimeters, the terminal buds of the eggplant seedlings are removed to promote the growth of side branches. When the eggplant plants have taken shape, we need to suppress plant growth and promote flowering, so the terminal buds of the side branches should be removed. In order to maintain the permeability of the plants, it is necessary to remove branches and leaves that are growing too densely, avoiding the occurrence of poor light and ventilation.
4. Reasonable temperature control
In greenhouse eggplant cultivation, the most important point is temperature management, because temperature has a very large impact on eggplant pollination. In order to improve the success rate of eggplant pollination, temperature management needs to be carried out reasonably. During greenhouse cultivation, temperatures that are too low or too high will affect eggplant pollination, making flower drop, fruit drop, and deformed fruit prone to occur, so we can appropriately spray some hormones to prevent flower and fruit drop, such as 2,4-D and 4-CPA.
