Coix lacryma-jobi L. cultivation method realizing soil moisture preservation in dry slope land, drought resistance and weed inhibition

Abstract

The invention discloses a cultivation method for coix coix sloping land with moisture conservation, drought resistance and weed suppression. The method uses yellow clay with strong moisture retention to wrap the seeds, which can reduce the evaporation of seed kernel water when the seeds germinate, and can fully absorb the soil when it rains. The moisture in the seed enhances the drought resistance ability of the seed. Simultaneously, in the present invention, the seeds are covered with side film, which can effectively reduce water loss in the soil and maintain soil moisture. When it rains, the rainwater flows into the seed rows on both sides through the film, improving the utilization rate of rainwater. Moreover, the black film is used to cover the weeds under the film to lose the photosynthetic conditions. At the same time, the film is used to physically block the pressure, so that the weeds cannot grow normally, which effectively saves the cost of weeding in the later stage. In addition, in the present invention, the seed row is covered with corn stalks, which can reduce the evaporation of soil moisture in the seed row and maintain soil moisture.

Description

technical field [0001] The invention relates to a coix coix cultivation method, in particular to a cultivation method for moisture conservation, drought resistance and weed suppression in dry slope land coix coix cultivation, and belongs to the technical field of agricultural planting. Background technique [0002] Coix lacryma-jobi L., also known as Coix lacryma-jobi L., is a medicinal and edible economic crop belonging to the genus Coix lacryma-jobi L. of the Poaceae family. It has important medicinal value and high nutritional value. Coix coix seeds are used as medicine after removing the shell and seed coat, which has the functions of invigorating the spleen and removing dampness, clearing heat and draining pus. Coix seed is one of the traditional food resources in my country, and its nutritional value can be called the king of gramineous plants. Qianxinan Prefecture of Guizhou Province is one of the main production areas of coix in the country, with the annual planting...

Problems solved by technology

[0003] The terrain of Guizhou is complex, fertile contiguous cultivated land is rare, and it is mainly barren dry slope mountain land. The main distribution area of ​​Guizhou Coix is ​​barren and arid dry slope mountain land. Due to the weak agricultural infrastructure in Guizhou, there is no irrigation and drought-resistant infrastructure, and Guizhou spring There is drought and little rain during the sowing period of coix coix. After sowing coix coix seeds by conventional methods, often due to poor soil moisture, no ground irrigation facilities, and scarce rainfall, coix coix seedlings often have few seedlings, irregular seedling emergence, and slow growth, which seriously affect the yield of coix coix. improvement
