Eggplant is a continuous bifurcated branch, and each leaf axil can be bred with side branches. If left to grow naturally, the branches and leaves will grow. It is easy to cause the phenomenon of long crops. Therefore, the adjustment of eggplant plants is the key technology to improve the yield and quality of eggplant. When will the eggplant be pruned? What are the methods of pruning? Let's go check it out!
Planting eggplant pruning method
The main method of eggplant pruning
The eggplant planting is divided into conventional planting and protected land planting in the open field. Generally, the conventional planting of the open field is rarely pruned, and the branches near the ground can be removed at most. The eggplant planted in the protected area is affected by the facilities due to the growing conditions. Pruning and smashing, shaping high-yield and high-quality plant types, ensuring ventilation and light transmission in the field, and improving the overall yield of eggplant. Eggplant pruning is mainly concentrated in the flowering period, and the number of planting and flowering results is controlled by pruning management. Generally speaking, there are four main methods for planting pruning in protected areas: single dry pruning, double dry pruning, three dry pruning, four dry pruning, and head pruning.
The main method of single and double dry pruning. The single dry pruning mainly removes all the side branches below the stalk, and retains a relatively thick result branch. This method has a large amount of early results and is suitable for plots with high planting density, but the plants are prone to premature aging and the amount of seedlings is large. The double-drying pruning mainly keeps the two branches growing at the same time when the eggplant is firstly branched, and only retains one after branching, and retains two result branches throughout the growing period. This pruning method is conducive to the concentrated supply of nutrients, can better improve the fruit rate of the commodity, and is suitable for dense planting plots. However, this method has a large seedling workload, and the plant root extension range is small, and premature aging is prone to occur.

The main method skills of three or four dry pruning. The three-dry pruning is to retain the secondary branches germinated on the retained primary branch as the result branch on the basis of the double dry pruning. The two secondary branches plus one primary branch have a total of three result branches, and the lateral branches growing on the three result branches are selected to be thickly retained, and the rest are erased. This method has a smaller plant shape and concentrated nutrition, which can improve the quality of early results, but the workload is large. The four dry pruning branches are also called double-twisted pruning, and the four secondary branches are used as the main result branches. The flank branches that grow out are selected to leave a thick branch and flowering results, and the rest are all erased. This method is suitable for small planting density, taking into account the early and overall yield, but due to the excessive retention of branches, the plant has poor ventilation and light transmission, and the overall commodity fruit rate is relatively low.

In addition to the above several pruning methods, there are more applications for head turning. The main method is to retain 2~3 leaves on the top of the fruit after the fruit is placed, and pick up the main stem, and keep the lower side branch. After the first fruit of the side branch is seated, keep 2~3 leaves to exfoliate and promote the germination of the lower side branch. The analogy can be pruned. Compared with the above several methods, the method can improve the uniformity and commercial fruit rate of the eggplant, reduce the height of the plant, and prolong the result period, and is especially suitable for grafting eggplant.
