Embodiment 1

[0009] Corn and peanut diversity planting disease control experiment, the corn variety is Xinghuangdan 892, the peanut variety is Fu 21, and 6 treatments are set up, namely: A (2 rows of corn intercropping and 2 rows of peanuts), B (2 rows of corn intercropping 6 row of peanuts), C (2 rows of corn intercropping and 8 rows of peanuts), D (2 rows of corn intercropping and 10 rows of peanuts), CK1 (single cropping of corn) and CK2 (single cropping of peanuts), the area of ​​each treatment is 120m 2 , The corn sowing period is the same as the peanut transplanting period. The row spacing of peanuts is 25cm and the row spacing is 30cm; the row spacing of corn is 40cm, and the row spacing between peanuts and corn is 40cm. The yield analysis is calculated based on peanut pods and corn kernels, and the output value is 3.00 yuan / kg for peanuts and 1.50 yuan for corn kernels. / kg calculation.

[0011] The analysis method of subsequent examples is the same as example one. ...

Embodiment 2

[0015] Corn and peanut diversity planting disease control experiment, the corn variety is Mobai No. 1, the peanut variety is Guihua 17, and 6 treatments are set up, namely: A (4 rows of corn intercropping and 4 rows of peanuts), B (4 rows of corn intercropping 6 Rows of peanuts), C (4 rows of corn intercropping and 8 rows of peanuts), D (4 rows of corn intercropping and 10 rows of peanuts), CK1 (single cropping of corn) and CK2 (single cropping of peanuts), the area of ​​each treatment is 220m 2 , The corn sowing period is the same as the peanut transplanting period. The row spacing of peanuts is 30cm; the row spacing of corn is 45cm, and the row spacing between peanuts and corn is 20cm.

Abstract

The invention relates to a method of controlling peanut brown spot and corn big spot by cultivating peanut and corn in heterogeneity, belonging to plant protection field. The technique project of this invention is: on the base of keeping the cultivating mode of peanut and corn, planting the two crops in displacement, the plant distance, line space and density between peanut and peanut, corn and corn is the same with normal cultivating method, planting peanut with different line ratio for interval cultivating, planting corn with 2-4 lines, peanut 2-10 lines, the line space between peanut and corn is 20-40cm. The invention can control the peanut brown spot and corn big spot with a good effect, can reduce the using amount of chemical pesticide greatly, increase product yield per unit area, and possesses outstanding economical, social and ecological benefit and wide application prospect.

Description

technical field [0001] The invention relates to a method for controlling peanut brown spot and corn leaf spot, belonging to the field of plant protection. Background technique [0002] Peanut is an economic crop widely planted in the world, and China is the second largest peanut producing country in the world. Peanut brown spot disease is a common and frequent disease in peanut production areas. It often causes a large number of leaves to fall in the middle and late stages of growth, and brings heavy losses to peanut production. Generally, the yield is reduced by about 20%, and the severe disease can reduce the yield by more than 50% ( Melouk and Shokes 1995). Due to the lack of peanut varieties with high resistance or immunity to brown spot disease, pesticide control is an important means of preventing brown spot disease in peanut production, but there is still about 10% peanut yield loss in chemical control. [0003] Corn is the third largest food crop in the world and t...
