Vegetable farmers in Shouguang City and Qingzhou City of Shandong Province generally leave four main branches when they are pruning and keeping branches of sweet peppers. Recently, when interviewed by Mengjiazhuang, Baocheng Street, Changle County, Shandong Province, the reporter found that many vegetable farmers also have four main branches and the same management method. However, the reporter found that when the local vegetable farmers planted sweet peppers, the area of ​​one acre was 1200-1500, while that of Shouguang City and Qingzhou City was about 2,000 per mu.
The difference in planting density of sweet peppers is large, and the number of main branches is the same, which in turn reduces production. Because there are four main branches on each sweet pepper, and 2000 trees and 1200 trees per mu, the output is worse than 800. Therefore, if 1200 bell peppers are to catch up with or exceed 2,000 in production, you must leave one or two more strong side branches on the basis of the original four main branches, so as to ensure the yield.
The sweet pepper is pruned in order to improve the ventilation and light transmission conditions in the field, improve the photosynthetic efficiency, promote the strong growth of the main branches, and concentrate the nutrients on the resulting branches, which is conducive to multi-picking peppers, forming large peppers, and improving the commerciality of the pepper fruits. At the same time, it is also to make each pepper branch and each fruit have reasonable growth space, and ensure that the sweet pepper has good quality and high yield. Especially for colored peppers, fruit shape and coloring are directly related to the price level and income, which is very important. Therefore, in the management of sweet peppers, reasonable pruning and retention are essential.
Therefore, when we pruning sweet peppers, we must first look at the planting density, and we cannot make the experience of others. The growth space of sweet pepper on acreage is certain, and the number of suitable growth branches is also certain. Planting practice shows that the number of main branches per acre of sweet peppers is preferably between 5000-7000. That is to say, when the planting density is 2000, 3-4 main branches are suitable for each plant; and when 1200 plants are planted per acre, 2 strong lateral branches are left on the basis of 4 main branches per plant.
