Problems solved by technology

Based on the original intercropping mode of cotton field, this mode expands the width of the crop planting strip according to the operating width of the agricultural machinery involved in the crops, so that the agricultural machinery can be directly operated in the field without modification; at the same time, within the crop strip The implementation of crop rotation can greatly reduce labor costs while improving land use efficiency and increasing output per unit area, and solves the problem of difficult operation of multi-cropping agricultural machinery in cotton fields

Embodiment 1

[0036] The test site is selected in Xizhangtou Village, Quzhou County, Hebei Province, with an area of ​​0.75hm 2. The strip width of the wide-band rotation mode is set to 6.0 meters and the length is 40.0 meters. The crop rotation sequence in the strip is cotton→wheat-corn→green manure crops (rape), and crops in adjacent strips are planted in staggered years. 8 rows of cotton are planted in the cotton belt, the variety is Ji 178, sown on April 24, 2018, the row spacing is 76cm, the plant spacing is 25cm, and the density of seedlings per mu is 4,000; 32 rows of wheat are planted in the wheat belt, and the variety Hanmai 14 is planted in 2018 Sow on October 25, with a row spacing of 18cm; plant 10 rows of corn in the corn belt, the variety is Denghai 605, sow on June 8, 2019, with a row spacing of 60cm, a plant spacing of 25cm, and a seedling density of 4,500 per mu; rapeseed September 23, 2019 Daily sowing, no watering or fertilization during the whole growth period, no rape...

Abstract

The invention discloses a planting mode of cotton-grain-green manure crop wide-strip rotation, and relates to the technical field of agricultural planting. The planting mode of the cotton-grain-green manure crop wide-strip rotation. The planting mode comprises the following steps: (1) breadth setting: setting strip breadth according to the least common multiple of the operation breadth of an agricultural machine used by all crops in the mode; and (2) crop selection: establishing a cotton-grain-green manure crop wide-strip rotation crop combination mode according to the principles of crop growth season end-to-end connection, spatial-temporal difference distribution in crop symbiotic period growth and crop resource utilization difference complementation; wherein crop combination mode is cotton-wheat-corn-green manure crops. The planting mode has the beneficial effects that the problem that mechanization cannot be achieved in a traditional multiple cropping mode is solved, the land utilization rate and the fertilizer utilization rate are increased, the harm index of diseases and pests is reduced, and yield and income increase of crops in unit area is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, and more specifically relates to a planting mode of wide-band rotation of cotton-grain-green manure crops. Background technique [0002] Cotton multiple cropping is an important multiple cropping means to improve cotton planting benefits. Including intercropping, intercropping, crop rotation, etc. [0003] At present, cotton intercropping represented by cotton-wheat intercropping is an important multiple cropping method to solve the land competition for grain and cotton and improve the efficiency of cotton planting. Cotton field intercropping is to plant other crops between cotton rows in the early stage of cotton growth, so that one more crop can be harvested in the cotton field, which not only makes full use of the land space and light and heat conditions between cotton rows in the early stage of cotton growth, but also increases the output per unit area. Improved land use effic...
