Embodiment 1

[0020] In Anding District, Dingxi City, where the annual rainfall does not exceed 400 mm, the selected silage corn variety is Zhongbei 410.

[0021] Select a hillside land without irrigation conditions, apply 3500kg / mu of decomposed farm organic fertilizer, 10kg / mu of 100 mesh fly ash, 5kg / mu of 100 mesh vermiculite, deeply plow the land 30cm, level and rake finely, and ridge along the contour line , ridge width 40cm, ridge spacing 30cm. When sowing, sow one row per ridge, each planting row is on the lower side of the ridge, 1-3 grains / hole, staggered hole sowing, odd-numbered rows are planted at a distance of 33 cm, and even-numbered rows are planted at a distance of 25 cm. Apply ternary compound fertilizer 25kg / mu, multivariate micro-fertilizer 3kg / mu to be base manure during sowing, topdress nitrogen fertilizer 18kg / mu in the jointing stage, nitrogen fertilizer in the described ternary compound fertilizer: phosphate fertilizer: the percentage by weight of potash fertilizer ...

Abstract

The invention provides a high-yield planting method for hilly land silage corns and belongs to the technical field of crop cultivation. The method includes the steps of soil selecting and preparation, seed selection and sowing, fertilizer application, drip irrigation and film mulching, and field management. After soil preparation and soil improvement are conducted, silage corns suitable for being planted on hilly land are selected for dislocated dibbling, a self-pressure drip irrigation system is used for water-saving drip irrigation, a back mulching film is used for covering, and finally the purpose of high yield and the purpose of income increasing are achieved on the silage corns cultivated on the arid and semi-arid hilly land.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, in particular to a high-yield planting method for silage corn on hillsides. Background technique [0002] Corn is one of the main grain crops in China. Its sown area and output both rank second in the world, and its annual output accounts for 20% of the world's total output. The traditional method of planting corn is single-plant cultivation in one hole. Due to various conditions, it is generally 4200-4700 plants / mu. Therefore, the root growth of crops, lodging resistance, corn pollination opportunities, surface water evaporation rate and night temperature Dispersion is not conducive to the growth of corn, resulting in the low yield of the planting method, poor grain quality and other shortcomings, increasing the planting density of corn will cause problems such as poor ventilation and light transmission, and resistance to wind. [0003] The current high-yield cultivation techniques for...
