夏季栽培甜椒易感染病毒,在甜椒行间套种玉米,利用玉米与甜椒植株高度差异大,叶和光具有互补效应,玉米叶77.0%集中于100~160 cm高度,辣椒80.0%主要分布在60~90 cm高度,二者占据不同的空间,配置层次化,为光透射创造条件;夏季利用玉米的植株高度为甜椒形成遮荫,有效地抑制甜椒的“日灼病”和病毒病的发生,同时利用玉米植株为甜椒趋避虫害,显著提高甜椒夏淡季产量,提高甜椒的品质,降低甜椒病虫害的发生,减少农药的使用量,增加土地产出率,社会效益明显,具有较高的推广前景。
The summer cultivated sweet pepper is susceptible to virus and intercropped with corn in the middle of sweet pepper line. The difference between plant height of corn and sweet pepper is large, and the effect of leaves and light are complementary. 77.0% of corn leaves are concentrated in height of 100 ~ 160 cm, 80.0% 60 ~ 90 cm height, the two occupy different space, the level of configuration, creating the conditions for light transmission; the summer height of the corn plant sweet pepper shade, effectively restrain pepper’s “sunburn” and At the same time, the use of corn plants as pests to avoid insect pests, significantly increase the summer sweet and sour peppers yield, improve the quality of sweet peppers, reduce pepper pests and diseases, reduce the use of pesticides, increase land productivity, social benefits Obviously, with high promotion prospects.
