Problems solved by technology

[0003] However, the disadvantages of the one-season monoculture mode of cotton and peanuts are: cotton is planted in large and small rows, with a density of about 3,000 plants per mu, and intensive cultivation and management throughout the growth period, including removing vegetative branches, topping (main stem tops and leaf branch tops), Smearing buds, intertillage and weeding, multiple plant protection and chemical control, harvesting flowers in batches, etc., require a lot of labor, high investment, poor efficiency, and serious rotten bolls in rainy years
However, this model is relatively simple, the selection of interplanting varieties is not clear enough, the interplanting technology is immature, and the economic benefits are not high, so it is difficult to rationally use the effective planting area to achieve high yield.

Embodiment 1

[0035] This experiment was carried out in Gaotang County, Liaocheng City in 2015 and 2016. The cotton and peanut intercropping rotation mode was adopted, and the intercropping method was 4 rows of cotton and 6 rows of peanuts. At the same time, pure cotton cropping, pure peanut cropping, 2 rows of cotton intercropping 2 rows of peanuts, 3 rows of cotton intercropping 4 rows of peanuts, and 5 rows of cotton intercropping 8 rows of peanuts were used as controls.

[0036]Peanut variety Huayu 36 and cotton variety K836 were used as test materials, and the land was cultivated in mid-March, and combined with the cultivated land, organic fertilizer and nitrogen, phosphorus and potassium compound fertilizer were applied as base fertilizers. In late March 2015, water was used to create moisture, and the soil was prepared before sowing, and 15 kg of pure nitrogen was applied per mu. Use mechanical ridges in the peanut pre-sowing row, the bottom width of the ridge is 76 cm, the back widt...

Embodiment 2

[0044] This experiment was carried out in Xiajin County, Dezhou City in 2015 and 2016. The intercropping mode of cotton and peanut was adopted, and the intercropping method was 4 rows of cotton intercropping and 6 rows of peanuts. At the same time, pure cotton cropping, pure peanut cropping, 2 rows of cotton intercropping 2 rows of peanuts, 3 rows of cotton intercropping 4 rows of peanuts, and 5 rows of cotton intercropping 8 rows of peanuts were used as controls.

[0045] Peanut variety Huayu 36 and cotton variety K836 were used as test materials, and the land was cultivated in mid-March, and combined with the cultivated land, organic fertilizer and nitrogen, phosphorus and potassium compound fertilizer were applied as base fertilizers.

Embodiment 3

[0053] This experiment was carried out in Gaotang County, Liaocheng City in 2015 and 2016. The cotton and peanut intercropping rotation mode was adopted, and the intercropping method was 4 rows of cotton and 6 rows of peanuts. At the same time, pure cotton cropping, pure peanut cropping, 2 rows of cotton intercropping 2 rows of peanuts, 3 rows of cotton intercropping 4 rows of peanuts, and 5 rows of cotton intercropping 8 rows of peanuts were used as controls.

[0054] The peanut variety Huayu 22 and the cotton variety Lumianyan No. 28 were used as test materials, and the land was cultivated in mid-March, and organic fertilizer and nitrogen, phosphorus and potassium compound fertilizer were applied to the cultivated land as the base fertilizer. In late March 2015, water was used to create moisture, and the soil was prepared before sowing, and 15 kg of pure nitrogen was applied per mu. Use mechanical ridges in the peanut pre-sowing row, the bottom width of the ridge is 80 cm, t...

Abstract

The invention relates to the field of crop planting, in particular to an intercropping method of cotton and peanuts. To increase the yield of the peanuts and cotton in the unit planting area, the intercropping method of the cotton and peanuts is provided. Six rows of peanuts are intercropped every four rows of cotton, and a spacing band with the width being 30-50 cm is arranged between a cotton sowing band and a peanut sowing band. The cotton and peanuts are intercropped, and the unit yield of the peanuts and cotton can be obviously increased; compared with mono-cultured cotton and peanuts, the average increasing yield of the cotton is 10-15%; the average increasing yield of the peanuts is 5% or above; according to the comparison between the intercropping mode under other proportion conditions and the proportion condition that six rows of peanuts are intercropped every four rows of cotton, the growing rates of the unit yield of the cotton and peanuts reach a maximum.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to an intercropping method for cotton and peanuts. Background technique [0002] The Yellow River Basin is an important cotton and peanut planting area in my country. The local area mainly adopts the traditional monoculture of cotton and peanuts, which are planted one season a year. [0003] However, the disadvantages of the one-season monoculture mode of cotton and peanuts are: cotton is planted in large and small rows, with a density of about 3,000 plants per mu, and intensive cultivation and management throughout the growth period, including removing vegetative branches, topping (main stem tops and leaf branch tops), The steps of smearing buds, intertillage and weeding, multiple plant protection and chemical control, and harvesting flowers in batches require a lot of labor, high investment, and poor efficiency. In rainy years, rotten bolls occur seriously. Single cropping and heavy ...
