High-yield planting method of interplanting pepper and corn to control diseases and pests

Abstract

The invention provides a high-yield planting method of interplanting pepper and corn to control diseases and pests, and belongs to the technical field of agricultural cultivation. The method comprises the following steps: pepper and corn are planted according to the field distribution of 8-10 rows of pepper and 2 rows of corn; the planting specification of pepper is that the row spacing is 40 cm and the planting spacing is 35 cm, and pepper is planted by single plant; the planting specification of corn is that the row spacing is 35 cm and the planting spacing is 30cm, and corn is planted by double plants; and pepper and corn are planted at an interval of 60 cm. The method has the benefits that dry hot pepper yield of pepper reaches 1935.63 kg/hm<2> to 2063.49 kg/hm<2>, increasing by 18% to 26%; capsaicin content is increased by 19% to 23%; vitamin C content in pepper is increased by 12% to 13%; corn yield is increased by 27% to 28%; and compared with single cropped pepper, the control effect on epidemic diseases of pepper reaches 47% to 56%, the control effect on helicoverpa assulta of pepper reaches 42% to 55%, and the incidence rate of diseases and insects is remarkably reduced.

Description

technical field [0001] The invention relates to a high-yield planting method for intercropping capsicum and corn to control diseases and insect pests, and belongs to the technical field of agricultural planting. Background technique [0002] Qiubei County is located in the southeastern part of Yunnan Province, in the low-latitude monsoon area, between 103°34′-104°45′ east longitude, 23°45′-24°28′ north latitude, and at an altitude of 1400-1800 m. The hometown of Chinese peppers", the peppers produced in this area are called "Qiubei peppers". The cultivation of "Qiubei Pepper" has a history of more than 350 years, and the scale of cultivation has been continuously expanding in recent years. However, the pepper planting method is backward, with large-scale contiguous single species as the mainstay, and the cultivation management is extensive; the variety is seriously degraded, the ability to resist diseases and insect pests is reduced, and the per unit yield is low; the fruit...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the backward planting methods and extensive cultivation management of Qiubei peppers, resulting in the decline of Qiubei peppers' ability to resist diseases and insect pests and low per unit yield.
