Pruning method for peppers

Abstract

The invention discloses a pruning method for peppers. Three primary lateral branches on a whole plant are selected and remained and three secondary lateral branches on each primary lateral branch are selected and remained. The pruning method comprises the following steps: S1, when a main stem of a pepper plant grows to 15-25 cm high, topping to promote germination of lateral branches; S2, when the lateral branches at middle and upper parts of the main stem grow to 3-5 cm long, selecting three lateral branches as primary lateral branches, and cutting off other germinated lateral branches on the main stem at the same time; S3, when 6-8 true leaves grow on the primary lateral branches, topping to promote germination of secondary lateral branches; S4, when the secondary lateral branches grow to 3-5 cm long, selecting three lateral branches from each primary lateral branch as secondary lateral branches, and meanwhile cutting off the primary lateral branches and other germinated lateral branches on the main stem; and S5, when cotyledons begin to become yellow, removing true leaves on the main stem in batches. The method has the advantages of improving a plant population structure, increasing the number of bearing branches and increasing bearing sites. Meanwhile, the method increases near-ground ventilation and light transmission of plants, reduces air humidity, improves photosynthetic efficiency, enables the plants to grow and develop more robustly, effectively controls plant diseases and insect pests and increases a fruit setting rate.

Description

technical field [0001] The invention belongs to the field of pepper cultivation, and relates to a pepper pruning method, in particular to a pepper pruning method for the purpose of increasing yield. Background technique [0002] Yield of pepper and other fruits and vegetables = number of plants cultivated per mu * average number of fruit per plant * average weight of single fruit. For the yield of specific small-fruited pepper varieties: (1) The plant size is basically determined, and the average number of cultivated plants per mu is also basically determined, and it is unlikely to increase the yield by planting more plants; (2) Small-fruited peppers , one of the characteristics of its fruit is "small", and the yield cannot be increased by increasing the weight of the single fruit. Therefore, increasing the average number of fruits per plant has become the main way to increase the yield of small-fruited peppers. Ways to increase the average number of fruits per plant: incr...

Occasionally, it is used to "top" the main stem of pepper during the plant growth period to promote the germination of side branches and increase the number of branches. However, this method usually does not limit the number of side branches and allows them to grow, often resulting in too many side branches. Mutual shading reduces fruit setting rate

[0008] CN201210335450.7 discloses a "a kind of capsicum unlimited cultivation pruning method", which first "topping or twisting" the side branches on the main pole, only interferes with the growth of the side branches, and does not remove the side branches; but waits until the side branches are growing In the later stage, all side branches are removed, which affects the ventilation and light transmission of pepper plants in the early stage of growth to a certain extent, and increases the risk of disease occurrence; Labor costs

[0009] CN 201810632146.6 discloses a "a method for pruning and picking leaves of peppers". This method removes all side branches and old leaves on the main stem in batches, but does not increase the fruiting sites of peppers by means of pruning, and improves the yield of small-fruited peppers. limited role
