A Detailed Explanation of the Role and Methods of Pepper Pruning and Branch Thinning
As the planting area of peppers continues to increase, more and more problems appear during the pepper growing period, and growers often solve some of these problems through pruning and branch thinning, thereby increasing yield and boosting income. So what role does pepper pruning and branch thinning play? Let's take a look below.
I. The role of pruning and branch thinning
The branches on the upper and lower parts of a pepper plant differ in their fruiting ability. Generally, the first- and second-order branches have strong fruiting ability, and afterward, as the number of branches increases, the fruiting ability gradually declines. Therefore, excess branches can be thinned out so that nutrients are concentrated in the fruiting branches, meeting the nutritional needs of the fruiting branches and significantly improving the fruiting rate of the entire plant. If these thin and weak branches are not removed in time, they will also consume a large amount of nutrients, which is likewise unfavorable for improving production efficiency. After thinning out useless branches, the plant's air and light penetration can also be increased, which is very necessary for fruit coloring and enhancing glossiness. When there is sufficient light, the fruits are bright and glossy with high commercial value; conversely, the fruits color lightly and appear dull, with poor commercial quality.
II. Methods of pruning and branch thinning
1. Three-main-branch pruning and branch thinning
This method is suitable for large-fruited varieties. After pruning, the plant type can be reduced and planting density increased, which is beneficial for fruit growth and development and fruit coloring. The method is to keep 3 first-order branches with good orientation and thick, strong growth when the fruit sets, and cut off the remaining branches of the same order from the base. On each main branch, 2 second-order branches with good branching angle and orientation can be kept, and the remaining branches of the same order are removed from the base.
2. Four-main-branch pruning and branch thinning method
This method is suitable for horn peppers and most sweet pepper varieties. It can extend the plant's growth period, make the root system thick and well developed, and give a high early yield, but it also has certain drawbacks, namely that air and light penetration will be affected to some extent. It is somewhat similar to three-main-branch pruning and branch thinning: when the fruit sets, select and keep 4 thick, strong, well-oriented branches as main branches, cut off the remaining branches of the same order from the base, then keep 1-2 branches on each main branch and thin out the remaining branches of the same order.
3. Multi-main-branch pruning and branch thinning method
This method is suitable for ox horn pepper and goat horn pepper varieties. It can make them bear more fruit, develop a well-developed root system, grow well, and yield high, but it will also result in poorer air and light penetration and a low early yield. When the fruit sets, select and keep 5-6 branches that are in different positions but thick, strong, and well oriented as main branches, cut off the remaining branches of the same order, keep 1-2 branches on each main branch as fruiting branches, and thin out the remaining branches as early as possible.
4. Irregular pruning and branch thinning method
This method is suitable for goat horn pepper varieties and for open-field, early-maturing cultivation of peppers. When the side branches on the plant grow to 15-18 cm, cut off the side branches below the first pepper. After fruiting, thin out some branches that are too dense, receive poor light, or grow weakly, according to the plant's growth vigor, field air and light penetration, and fruiting conditions.
