example 1

[0022] Planting example 1: Corn and peanut row ratio 2:4 intercropping

[0023] During the whole growth period of summer maize and peanut, the density control experiment was carried out. The test site was the experimental field of the Crop Research Institute of Shandong Academy of Agricultural Sciences, the middle and low fertility plot, Sangyuan Road, Licheng District, Jinan City, Shandong Province. Ludan 818 was selected as the experimental variety of corn, and Huayu 25 was selected as peanut, both of which are excellent varieties independently selected by Shandong Academy of Agricultural Sciences and suitable for popularization and planting in the Huanghuaihai region. The planting modes were maize-peanut row ratio 2:4 intercropping (including corn conventional intercropping and corn intercropping with reduced spacing and increased density) and corn conventional monocropping, with a total of 6 planting modes and 3 repetitions.

[0024] The specific experimental design is as ...

[0041] Planting example 2: Corn and peanut row ratio 2:1 intercropping

[0042] During the whole growth period of summer maize and peanut, the density control test was carried out. The test site was the family farm of Zhonggong Town, Licheng District, Jinan City, Shandong Province, a plot of medium and low fertility. Ludan 818 was selected as the experimental variety of corn, and Huayu 25 was selected as peanut, both of which are excellent varieties independently selected by Shandong Academy of Agricultural Sciences and suitable for popularization and planting in the Huanghuaihai region. The planting modes were maize-peanut row ratio 2:1 intercropping (including maize conventional intercropping and corn intercropping with reduced plant spacing) and maize conventional monocropping, with a total of 6 planting modes and 3 repetitions.

[0059] Planting example 3: Corn and peanut row ratio 2:2 intercropping

[0060] During the whole growth period of summer corn and peanut, the density control experiment was carried out. The test site was Longshan Experimental Base, Zhangqiu City, Maize Research Institute, Shandong Academy of Agricultural Sciences, a plot of medium and low fertility. Ludan 818 was selected as the experimental variety of corn, and Huayu 25 was selected as peanut, both of which are excellent varieties independently selected by Shandong Academy of Agricultural Sciences and suitable for popularization and planting in the Huanghuaihai region. The planting modes were maize-peanut row ratio 2:2 intercropping (including corn conventional intercropping and corn intercropping with reduced plant spacing) and corn conventional monocropping, with a total of 6 planting modes and 3 repetitions.

Abstract

The invention belongs to the technical field of crop cultivation and provides a corn and peanut intercropped planting mode for grain yield stabilizing and oil production increase. 1-4 rows of peanuts are intercropped at intervals of every two rows of corns in a strip-shaped mode, namely the row ratio of the corns to the peanuts is 2:(1-4); every two rows of corns and 1-4 rows of peanuts form an intercropping combined zone, the zone width of the intercropping combined zone is 200 cm; each intercropping combined zone starts from the corn rows, every two rows of corns and 1-4 rows of peanuts are sequentially arranged, the row spacing of every two rows of corns is 60 cm, the row spacing between each corn row and the adjacent peanut row is 40-70 cm, the row spacing of every two adjacent peanut rows is 20-60 cm, the plant spacing of the corns is 10-16 cm, and the hole spacing of the peanuts is 20-40 cm. In the corn and peanut intercropped planting mode, the corn yield is basically equal to the yield of singly-cultured corns, the amplitude of yield variation is within the range of + / - 3%, accordingly the purpose of peanut production increase while corn yield stabilizing is achieved under the condition that no additional land is input, namely groundnut kernels and peanut vines are 'obtained without effort', and the contradiction of contention for grain and oil land in our country can be effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a planting mode of corn and peanut intercropping for stabilizing grain and increasing oil, in particular to a kind of summer corn and summer peanut intercropping during the whole growth period, which can ensure that the yield of intercropping corn is basically the same as that of single cropping, without additional land input The "stabilizing grain and increasing oil" intercropping planting method of increasing peanut income under the condition of unforeseen circumstances. Background technique [0002] Ensuring food safety and oil safety is a major strategy for my country's economic development. At present, my country's grain self-sufficiency rate has dropped to about 88%, and the edible oil self-sufficiency rate is less than 35%. The urgency of ensuring food security and oil safety is becoming increasingly severe. Under the premise that my country's grain and oil plantin...
