Embodiment 1

[0100] 1. Plot selection

[0101] Choose fields with deep soil, good structure, soft texture, moderate fertility, pH 6.5-8.0, and flat terrain. Bean crops are the best in the previous cropping, followed by corn, peanuts and other crops, and it is not suitable for repeated cropping and stubble cropping. Avoid soil pesticide residues that may cause phytotoxicity to sorghum in previous crops.

[0102] 2. Film selection

[0103] Choose agricultural mulch films produced by large formal enterprises that meet national standards.

[0104] 3. Soil preparation before sowing

[0105] (1) Deep plowing and drying in autumn

[0106] Choose suitable machines and tools, and deep plow and sun-dry in autumn after the previous crops are harvested, with a plowing depth of 25cm to 30cm.

[0107] (2) Rotary tillage and film mulching in early spring

[0108] In early spring, use a rotary tillage and mulching machine to mulch and mulch the film to ensure that there are no large soil clods and r...

Abstract

The invention belongs to the technical field of mechanical agricultural planting, and discloses a mechanical mulching-film cultivation method for sorghum. The mechanical mulching-film cultivation method for the sorghum comprises the specific steps that a mass of land is selected; land preparation before seeding is conducted, wherein the variety and quality of sorghum seeds are selected; the selected sorghum seeds are treated and sowed, and fertilization and chemical weeding are conducted; intertillage, hilling and fertilization are conducted by using an intertillage, hilling and fertilization integrated machine in the elongation stage; intertillage is conducted in wide lines through wide-narrow line planting; irrigation and drainage are conducted; pest and disease control is conducted; after grains completely ripen and leaves die back, when the water content of the grains is reduced to about 20%, mechanical harvesting is conducted by using a sorghum grain harvesting machine; when there is no special sorghum grain harvesting machine, modified harvesting can be conducted by using a wheat harvesting machine or a soybean harvesting machine; by using a mulching film removal machine and a straw returning machine, the sorghum land obtained after mechanical harvesting is subjected to mulching film removal, straw returning, and stubble cleaning and film residue cleaning are conducted.

Description

technical field [0001] The invention belongs to the technical field of mechanized agricultural planting, and in particular relates to a sorghum mechanized plastic film cultivation method. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The technologies mainly promoted in dry farming areas include full-film double-furrow sowing technology, half-film mulching sowing technology, and film-side sowing technology. The promotion of these technologies is of great significance for increasing agricultural income, but it is difficult to realize the whole process of mechanized integration. [0004] Existing sorghum mostly adopts the planting method of loose seeds, which is highly dependent on the weather, and the soil moisture and surface temperature cannot be effectively improved, which affects the yield and quality. [0005] In summary, the problems in the prior art are: [0006] The existing technology is ma...
