Description

Method for cultivating coix in dry slope
Technical Field
The invention belongs to the technical field of coix planting, and particularly relates to a method for cultivating coix in a dry slope.
Background
Coix lacryma-jobi is a green food with high protein, medium fat, medium sugar and rich zinc, and has high nutritive value and medicinal value, and its nutritive value can be called "king of gramineous crops". The coix seed contains 17 amino acids necessary for human body, in which the leucine content can be up to 19.0 microgram/Mg, the glutamic acid content can be up to 42.7 microgram/Mg, the alanine content can be up to 14.6 microgram/Mg, and also contains several trace elements of Ca, Cu, Fe, Mg, Mn and Zn, etc., and these elements are necessary for human body. In addition, the coix contains active ingredients such as coixenolide, coixol, feruloyl stigmasterol, coix polysaccharide, neutral glucan and the like, and has the effects of resisting tumors, reducing blood sugar, reducing blood fat, improving immunity, relieving pain and the like.
The coix lacryma-jobi is warm in nature, sunny and humid, is not low-temperature resistant, is suitable for being planted at the altitude of 600-1500 m, the average annual temperature is not lower than 15 ℃, the suitable growth temperature is 15-30 ℃, the suitable rainfall is 800-1500mm, and is particularly suitable for being developed and planted in Guizhou province. Guizhou province, Qianxuan, is one of the major producing areas of Coix lacryma-jobi in China, the planting scale is kept about 50 ten thousand mu throughout the year, and the Guizhou province, Qianxiang, is a characteristic economic industry of Guizhou agriculture. However, Guizhou province belongs to a karst region, the terrain and topography are complex, fertile continuous piece cultivated land is rare, the arid hilly regions which are barren are mainly used, and the main distribution area of the coix lacryma-jobi is the arid hilly regions which are barren; because the Guizhou agricultural infrastructure is weak, irrigation drought resisting infrastructure is not provided, and the Coix lacryma-jobi is dry and rainy in the sowing period in spring of Guizhou, the Coix lacryma-jobi seeds are sowed by the conventional method, and the situations of few seedlings, irregular seedlings, slow growth and the like of the Coix lacryma-jobi are often caused by poor soil moisture content, no ground irrigation facility, rare rainfall and the like. In addition, the soil in the Guizhou province is generally acid soil, and the rainfall is mainly acid rain, so that the effectiveness of soil nutrients is reduced, a good soil structure is difficult to form, the activity of inhibiting soil microorganisms is seriously influenced, and the growth and development of the coix are influenced. Based on this, many researchers have studied the cultivation technique of Job's tears in Guizhou region.
The patent with the application number of CN 201610263344.0 discloses a cultivation method for preserving soil moisture, resisting drought and suppressing weeds of coix lacryma-jobi dry slopes, which comprises the following steps: (1) wrapping seeds in soil: mixing soil and water, stirring to obtain paste, and stirring Coicis semen seed and pasty soil to coat Coicis semen seed with soil; (2) seed drilling: ditching and sowing the coix seeds wrapped by the soil according to the row spacing of 40cm and the row spacing of 80cm, wherein the ditching depth is 20cm, and applying a base fertilizer before sowing; (3) and (3) side film covering: covering a plastic film on the unsown soil in the middle of the adjacent seed rows, wherein the region covered by the film is free of coix seeds; (4) covering the seeds with straw: covering the seed sowing rows with corn straws, and covering the corn straws on the soil of the seed sowing rows; (5) withdrawing straws and managing in a later period: and after the seeds bud and break the soil to emerge, immediately removing the corn straws on the planting rows, and performing later-stage management according to a conventional coix seed water and fertilizer management method. The technology disclosed by the patent is a research conducted by researchers of the invention in the early stage, the technology mainly aims at reducing soil moisture loss and improving rainwater utilization rate, but the problems of serious pest and disease damage and difficult control of the coix caused by a mode of covering the coix by a plastic film and corn straws, and the problems of low utilization rate of soil nutrients and slow growth and development of the coix are solved.
