The invention relates to the technical field of crop cultivation, in particular to a method for cultivating dry-land cabbage type spring rapes through mechanized plastic mulching and hole sowing. Themethod sequentially comprises the following steps of land selection and preparation, base fertilizer application, seed dressing, plastic mulching and hole sowing machine selection, mechanical plasticmulching and hole sowing and field management. The mechanized plastic mulching and hole sowing technology is convenient and simple, the fertilizer application, field arrangement, pollution-free insectprevention and other technologies are reasonable, the yield and economic traits of the spring rapes can be improved better, the labor cost is reduced, and the possibility of whole mechanization and fertilizer and pesticide reduction during the dry-land cabbage type spring rape cultivation is achieved; compared with the prior art, the method for cultivating the dry-land cabbage type spring rapes through mechanized plastic mulching and hole sowing specifically has the advantages that (1), the completely-efficient and quickly-efficient nutrient content and organic matter content of soil are increased, and the pH value of the soil is effectively reduced; (2) the plant height, branch number, silique number, thousand seed weight and other economic traits of the spring rapes are obviously increased; (3) the average yield of a demonstration area is 4863.9kg per hectare and is 2.57-28.68% higher than that of open-field culture in the demonstration area.
