Embodiment 1

[0010] The energy-saving drying method for processing forage grass of smooth-leafed vetch of the present invention comprises stubble retention of previous crops, mowing, drying in the sun, baking and crushing.

[0011] The technical principle is: when the previous crop is harvested, the height of the stubble straw is 50~60cm. When the smooth-leaved sweet potato grows to the initial bud stage, it is mowed, and the stubble straw of the previous crop is used as a support to hang the harvested sweet potato directly. It is dried on it, and the leaves are withered and baked in the barn, and finally crushed into grass powders of different thicknesses. When drying, use the stubble straw of the previous crop as a support, with a height of 50-60cm, and hang 0.5kg-1.5kg of vetch on each support to maximize the use of solar energy and save environmental protection.

[0012] The energy-saving drying method specifically includes the following steps:

[0013] (1) Stubble of the previous cro...

Abstract

The invention discloses a method for energy-efficient dry-curing of forage grass made of smooth vetch. According to the method, during preceding crop harvesting, stubble which is 50-60 cm high is kept, smooth vetch is cut in the initial bud stage, remaining stubble of preceding crop is used as a support, cut smooth vetch is bundled with each bundle weighing 0.5-1.5 kg, the bundles are directly placed on the support to be dried in the air and then placed in a curing barn to be baked after blade withering, and finally smashing is conducted to obtain grass meal with different granulate sizes. The remaining stubble of preceding crop is used as a support during dry-curing, solar energy is utilized to the maximum degree in the air-drying process, energy conservation and environment protection are realized, and economic value is increased; meanwhile, soil structure can be improved during planting, soil fertility can be improved, both agriculture and animal husbandry are benefited, and the method has important significance for income increase of farmers, environment protection, energy-efficient agricultural technology development and sustainable agriculture development.

Description

technical field [0001] The invention mainly belongs to the technical field of crop planting, and in particular relates to an energy-saving drying method for processing forage grass from sweet-leafed vetch. Background technique [0002] Due to the expansion of urbanization construction land and the excessive use of chemical fertilizers, the quantity and quality of cultivated land have declined. Planting green manure can not only promote the rational use of land, ensure food security, improve soil fertility, and improve environmental quality, but also fix, activate, Enriching nutrients for crop use, increasing and improving soil organic matter, maintaining water and soil, and improving the ecological environment are important crop rotation measures in crop planting systems, which are of great significance for reducing pests and diseases and developing ecological agriculture. At the same time, green manure can be produced and utilized in different ways. It can not only be used ...
