Embodiment 1

[0025] From April 2014 to November 2016, planting experiments were conducted in the Science and Technology Demonstration Park of the Liaocheng Academy of Agricultural Sciences, Chiping County, Liaocheng City, Shandong Province, and plots with consistent fertility, soil quality and lighting were selected for three consecutive years of production trials and field management Both are consistent with the local field production level. The cotton test species is cotton line Liaomian No. 6, and the peanut test species is peanut variety Huayu No. 36.

[0026] On April 23, 2014, it was intercropped with 2 rows of cotton and 4 rows of peanuts. The width of the cotton sowing belt is 170 cm, and that of the peanut sowing belt is 170 cm. 2 rows of cotton and 4 rows of peanuts are arranged alternately, wide mechanized intercropping, and the row spacing and plant spacing of cotton and peanuts, and the distance between cotton rows and peanut ridges are strictly limited.

[0027] The cotton is 2 r...

Embodiment 2

[0045] From April 2014 to November 2016, a planting experiment was conducted in Guanxian County, Liaocheng City, Shandong Province. The plots with consistent fertility, soil quality and lighting were selected. The cotton test species was cotton strain Liaomian No. 6, and the peanut test species was The peanut variety is Huayu 36. The specific operation method is the same as the first embodiment.

[0046] On April 24, 2014, according to 2 rows of cotton and 4 rows of peanut intercropping, a cotton seeding belt with a width of 170 cm and a peanut seeding belt with a width of 170 cm were formed, and the final harvest was calculated.

[0047] On April 21, 2015, according to 4 rows of peanuts and 2 rows of cotton strip intercropping, cotton and peanuts were planted in reverse stubble, that is, peanuts were planted in the strips of cotton in 2014, and cotton was planted in the strips of peanuts in 2014. Produce.

[0048] On April 26, 2016, the intercropping of two rows of cotton and four...

Abstract

The invention provides a high-yield cultivation method adopting cotton-peanut intercropping in a year and inter-annual local crop rotation. According to the technical scheme, the method includes: cotton and peanuts are sown at the same time in the first year, four rows of peanuts are planted in a strip-shaped and intercropping manner after every two rows of cotton are planted in a strip-shaped manner, and alternating intercropping of the cotton sowing strips and the peanut sowing strips is performed; the cotton and the peanuts are sown at the same time in the second year, local crop rotation is performed, two rows of cotton are planted in a strip-shaped manner after every four rows of peanuts are planted in a strip-shaped manner, and alternating intercropping of the peanut sowing strips and the cotton sowing strips is performed. The method has the advantages that growth is regulated by the different space and time sequence configurations of the cotton and the peanuts, stress resistance is increased, yield is guaranteed and stabilized, successive cropping obstacles are relieved, and high yield of both the cotton and the peanuts is achieved.

Description

Technical field [0001] The invention relates to a cotton-peanut intercropping and inter-annual in-situ rotation high-yield cultivation method, belonging to the technical field of cotton and peanut farming. Background technique [0002] According to the influence of factors such as agricultural land conditions, farmers’ planting habits and social environment, a number of specialized crop planting areas have emerged in my country. Especially due to geological characteristics, many crops cannot be planted alternately, resulting in long-term Continuous cropping creates obstacles to continuous cropping. Continuous cropping obstacles refer to the phenomenon of planting more than two crops of the same crop or crops of the same family in the same field, even under normal cultivation and management measures, which will weaken the growth of the plants and decrease the yield and quality. Continuous cropping obstacles often make crops grow poorly and cause serious diseases and insect pests, ...
