Problems solved by technology

[0005] The above patent application documents use wide and narrow rows, which is not conducive to mechanized operations. At present, mechanized sowing and mechanized harvesting of wheat and corn have been basically realized. Failure to implement mechanized operations will seriously affect production efficiency and is not suitable for large-scale planting.

Embodiment 1

[0060] The wheat-spinach-corn-green manure intercropping cultivation method comprises the following steps:

[0061] (1) During the first soil preparation, in the first ten days of October of the first year, the planting land is irrigated with an irrigation volume of 35 square meters per mu. After 5 days of irrigation, base fertilizer is applied to the planting land, and then deep plowing is carried out. The land is divided into several planting belts with a width of 1.5m, and the planting belts are divided into wheat planting belts and spring corn planting belts, and the wheat planting belts and spring corn planting belts are arranged alternately;

[0062] The amount of base fertilizer applied is: 150 kg / mu of organic fertilizer, 45 kg / mu of special fertilizer for wheat;

[0063] When returning the last stubble corn stalks to the field, mix 12 kg of urea per mu with 35 kg of water to dissolve, and then spray evenly on the surface of the straw, and at the same time, sprinkle 1....

Embodiment 2

[0076] The difference with Example 1 is that in Example 2, (1) the base fertilizer is: the nutrient is N15kg / mu, P 2 o 5 7kg / mu and K 2 O 8kg / mu of elemental fertilizer; the elemental fertilizer is urea, superphosphate, and potassium sulfate. All the other are identical with embodiment 1.

Embodiment 3

[0078] The difference with embodiment 1 is that in embodiment 3, (1) the bandwidth of planting belt is 2m, all the other are identical with embodiment 1.

Abstract

The invention relates to a wheat-spinach-corn-green manure intercropping cultivation method. The present invention comprises the following steps: one-time land preparation; sowing winter wheat and spinach; weeding and insecticide; harvesting spinach, turning green to irrigate wheat, planting spring corn; harvesting winter wheat, planting summer corn; applying corn fertilizer; irrigating corn, weeding, insect and disease prevention Harvest spring corn, sow green manure plants, prepare the ground for the second time, and plow the green manure plants in; exchange planting with spring corn belts and wheat belts, and repeat the above planting steps. In the present invention, intercropping and interplanting five kinds of plants including winter wheat, spinach, spring corn, summer corn and green manure not only conforms to their cultivation habits, but also makes full use of the mutually beneficial relationship between different plants to form a reasonable composite population structure and improve the population growth rate. The variety of stress resistance avoids the phenomenon of soil diseases in the process of single crop rotation mode, improves the quality of soil cultivated land, and makes up for the defects of low benefit of single grain and low sustainable production capacity of soil.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a wheat-spinach-corn-green manure intercropping cultivation method. Background technique [0002] The traditional intercropping mode mostly relies on manual planting, which has high labor intensity, low economic benefits and is not conducive to the development of mechanization, which seriously restricts the process of agricultural mechanization in this area and discourages farmers' enthusiasm for farming. [0003] In terms of crop planting, single-cropping and continuous cropping are the traditional planting patterns. Single-cropping and continuous cropping are likely to cause heavy cropping. Changing cropping and intercropping are effective ways to overcome heavy cropping. However, winter wheat is the only two-year crop that survives the winter. It is sown in early October every year, and matures and harvests in early June of the second year after ov...
