Problems solved by technology

Green manure can provide rich nutrients for the soil, transform insoluble nutrients in the soil, improve the physical and chemical properties of the soil, and promote the activities of soil microorganisms.
[0005] The research on the technology of multiple cropping of leguminous green manure crops in wheat fields is very incomplete so far, and no mature technical means have been formed.

Embodiment 1

[0030] The rain-fed wheat field of about 1000 mu in Shilipu Village, a rain-fed wheat field production area in Changwu County, Shaanxi Province, was selected as the experimental field.

[0031] Choose a suitable soybean variety - Changwu Huaidou, Changwu Huaidou is a soybean variety widely planted in Changwu County, Bin County, Shaanxi Province, Lingtai County, Gansu Province and their surrounding areas. Harvest in the middle and late ten days. The plant height is about 60 cm, the leaves are dark green, brown velvet, white flowers, the growth period is 110-120 days, the seeds are brown-brown red, oval, and the weight of 100 seeds is 10-12g.

[0032] In the present embodiment, the method for replanting leguminous green manure crops in the wheat field is to sow with moisture grabbing after the harvest of the previous winter wheat. figure 1 shown):

[0033] (1) Soil preparation: Generally, in mid-June, after the harvest of the previous winter wheat, soil preparation is carried ...

Embodiment 2

[0040]About 1000 mu of rain-fed wheat field in Yujiagong Village, a rain-fed wheat field production area in Yongshou County, Shaanxi Province, was selected as the experimental field.

[0041] Choose a soybean variety suitable for planting - rye beans.

[0042] The method for multiple planting leguminous green manure crops in the wheat field of this embodiment specifically includes the following steps (such as figure 1 shown):

[0043] (1) Soil preparation: Generally, in late June, after harvesting the previous winter wheat, the soil will be soil-robbed and soil-prepared, and a rotary tiller will be used to plow and remove the stubble. It has been determined that the organic matter content of the local soil is 6g / kg, which is lower than 10g / kg, which belongs to low-fertility soil , so apply 40 kg superphosphate per mu;

[0044] This step can also be replaced by: not plowing after the winter wheat is harvested, and retaining the stubble land after the wheat is harvested.

Abstract

The invention mainly belongs to the technical field of crop planting, and particularly relates to a method for multicropping a leguminous green manure crop in a wheat field. The method for multicropping the leguminous green manure crop in the wheat field comprises the steps of: soil preparation, sowing, turning of the leguminous green manure crop and sowing of later-crop winter wheat. The method for multicropping the leguminous green manure crop in the wheat field specifically comprises: after harvesting previous-crop winter wheat, suddenly sowing the leguminous green manure crop while soil is moist, wherein the sowed leguminous green manure crop is a mung bean species or a soybean species; and when the leguminous green manure crop grows to a full-blossom period, turning the leguminous green manure crop as a fertilizer. The method provided by the invention can be used for quickly fertilizing soil, effectively reducing the use level of chemical nitrogen fertilizers, and remarkably improving the utilization ratio of chemical fertilizers.

Description

technical field [0001] The invention mainly belongs to the technical field of crop planting, and in particular relates to a method for replanting leguminous green manure crops in a wheat field. Background technique [0002] The content of organic matter in the plow layer of soil in my country is generally between 5 and 50g / kg, but in some areas the content of organic matter in the plow layer of soil is relatively low. main distribution area. Among them, two-thirds of the farmland in the Loess Plateau has an organic matter content of less than 10g / kg in the surface layer (0-10cm), and the other third has only 10-15g / kg of soil organic matter. [0003] Winter wheat is an important food crop. In areas with poor soil, drought and little rain, the production level of winter wheat has been low and unstable. Traditionally, the method to increase the yield of winter wheat is often to increase the amount of chemical fertilizers, but increasing the amount of chemical fertilizers will...
