Embodiment

[0008] 1. Study the crop combinations suitable for the diverse planting of corn and potatoes to control the main diseases, and determine the best planting mode suitable for the diverse crops. After multiple experiments, the diverse planting combinations of 4 varieties of maize and 3 varieties of potatoes have been screened out. Five kinds of diverse planting pattern experiments have been completed, A, 2 rows of corn with 2 rows of potatoes; B, 2 rows of corn with 4 rows of potatoes; C, 3 rows of corn with 3 rows of potatoes; D, 4 rows of corn with 2 rows of potatoes; E. 4-row corn set 4-row potato experiment. F, net corn. The results showed that the planting pattern of 2 rows of corn and 2 rows of potatoes had the best control effect on maize small spot, and the planting pattern of 4 rows of corn and 4 rows of potatoes had the best control effect on maize leaf spot, and the planting pattern of 2 rows of corn and 2 rows of potatoes The cropping pattern yields the best grain. ...

Abstract

The present invention is diversity corn and potato planting method to control corn northern leaf blight and southern leaf blight. The technological scheme of the present invention keeps available corn and potato planting mode, and features that in the same field, 2-4 rows of corn and 2-4 rows of potato are planted alternately, the row spacing between corn and potato is 30-60 cm and potato is seeded 20-35 days before corn is seeded. The corn variety may be any one of height over 1.5 m.

Description

technical field [0001] The invention relates to a method for controlling corn diseases, and its technical field belongs to the subject of plant protection. Background technique [0002] In the agricultural production with a long history in our country, the working people have the experience of mixing varieties and crops in practice to achieve better disease prevention effect and obtain more yield. For example, interplanting corn and soybeans, and corn and peanuts can increase grain production; in some rural areas in Sichuan, Chongqing, and Yunnan, farmers know that interplanting corn and potatoes can prevent diseases. For a long time, the phenomenon of controlling pests and diseases by these biodiversity has not been systematically studied in depth, and there is no optimal planting model, let alone reveal its internal mechanism, so it has not been widely applied in production. Contents of the invention [0003] The main purpose of the present invention is to overcome the ...
