Farmers who grow eggplant know that eggplant is a vegetable crop with strong branching ability. If the branch grows naturally, it will inevitably cause branches and leaves, and it is prone to uneven branching, branching and fruit competing for nutrients. The problem of poor ventilation and ventilation in the lower part. Therefore, timely pruning of eggplant is a necessary management method.
The pruning of eggplant is relatively simple, mainly used in greenhouse greenhouses. Generally, the eggplants grown in open field do not need to be pruned, and the method of pruning selection should be flexibly applied according to the characteristics of the variety. Let's talk about the three pruning methods commonly used for eggplant, the applicable plots and the pruning notes for your reference.
First, three kinds of pruning methods commonly used in eggplant
1. Single dry pruning method
It means that each time the eggplant is forked, the strong branching is retained and the weak branches are removed every time, so that only one result branch is retained during the whole growth period of the eggplant plant; or the side branches of the eggplant are all destroyed, leaving only the main Stems as a result branch. The single dry pruning method should be topped on the basis of retaining 2-3 leaves after the result of the first side branch.
The single dry pruning method is suitable for use on plots with high planting density, early maturity, and high yield in the early stage, but it is relatively large in manual input, and it is easy to cause premature aging of eggplant.
2, double pole pruning method
It means that at the beginning of the first bifurcation of eggplant, two branches are selected to grow at the same time. After the plant, one branch is retained for each branch, and another branch is removed, so that the whole growth period of the eggplant body Always keep the two result branches; or after the stevia grows out, keep the fruits on the main stem and the side branches, and wait until the emergence of the eggplant, then select a strong branch in the reasonable part to make the result branch, and promptly remove the other All side branches, sprouts, and then cycle through. The double-bar pruning method can retain 2-3 leaves on top of the top fruit for topping.
The double-rod pruning method is more suitable for the cultivation of eggplant in the greenhouse, which can make the nutrient concentration more and produce more high-quality fruit, but it is easy to cause the eggplant to grow long.
3, three-bar pruning method
It means that when the first flower is planted, the two side branches immediately below the flower are preserved, and all other side shoots are removed, so that the eggplant can form three fruiting branches with the main branch and the two side branches growing at the same time; After the stevia grows, in addition to retaining the main branch, the first and second side branches below the stalk are retained to make the result branches, and all other side branches are removed. After the eggplant is placed, each branch retains 1 branch result. On the basis of this, continue to remove other branches, so that only three fruits per layer of the plant, so cycle. In the last fruit, 1-3 leaves were preserved for topping.
Three-bar pruning is more suitable for planting with higher density, low plant type, medium fruit size, slender leaves, and early maturity varieties, which can make plants more fruitful.
In addition to the above three pruning methods, eggplant has four dry pruning methods, natural happy pruning method, multi-head pruning method, continuous topping method, etc., but the single dry pruning, double pruning and three pruning are most commonly used, others are not Let me introduce it in detail.
Second, the attention of eggplant pruning
1. The side branches, side buds, leaves, etc., which are removed after the pruning of the eggplant, should be taken out in time to be burnt out or deeply buried.
2. When the eggplant is pruned, the yellow, fading and weak leaves of some plants can be removed according to the number of results, which can reduce the occurrence of flowering, diseased fruit and poor coloring.
3. After the pruning of the eggplant, the leaves should be picked. The leaves should be flexibly determined according to the variety, growth, weather, fertility and other factors. The land with high fertility, rain and foot, and strong branches can pick more leaves and have poor fertility. The varieties with poor dry weather and poor branching ability should be picked less properly; generally, the whole growth period of eggplant picking leaves needs to be carried out 4-5 times. The number and number of specific leaf pickings should be determined flexibly according to the cultivation condition of the own eggplant.
4. When pruning the eggplant plants, do not smash the branches directly by hand. They should be constructed with pruning sharpness to prevent excessive tearing or infection by diseased bacteria.
The above is the problem of eggplant pruning, so when you manage, in order to make the eggplant more knotted fruit and produce more high-quality big fruit, it is necessary to carry out artificial pruning, topping, and threshing, and eggplant pruning is also realized. A key management technique for high yield and yield of eggplant.

Gaba receptor cells uptake alcohol during consumption and the resulting loss of function from loss of GABA uptake produces the effects of intoxication.)
