Feed-based utilization method for instantly recovering and fermenting rice and wheat straw

Abstract

The invention discloses a feed-based utilization method for instantly recovering and fermenting the rice and wheat straw, which belongs to the technical field of the straw recycling utilization. A device designed with the method structurally comprises an agricultural tractor, a straw packing machine, an automatic sprinkling device for straw ensiling fermentation liquor and a film covering machine. According to the growth characteristics of the rice and the wheat, the rice and the wheat are harvested in time in the later fructifying and grouting period of the rice and the wheat; the generated straw is collected and covered with the film by the device in 3-5 days; when the straw is collected, the agricultural tractor is operated in field to drive the straw packing machine to collect the straws; meanwhile, the automatic sprinkling device for straw ensiling fermentation liquor sprays and inoculates the fermentation liquor to a straw bundle which is gradually largened in the packing machine via a straw packing machine fermentation liquor feeding hole; when the diameter of the straw bundle is 50cm, the straw bundle is bundled and is fed out from a straw bale feeding hole; after being fed out, the straw bundle is transported to a storage place in 2-3 hours; the film covering machine is used for covering the film on the straw bundle for sealing, ensiling and fermenting; and the straw bundle is used as the ensiling feed of grass-feeding livestock. According to the feed-based utilization method for instantly recovering and fermenting the rice and wheat straw, which is disclosed by the invention, the straw resource can be simply utilized in an instant-collection and feed-based mode at low cost.

Description

technical field [0001] The invention relates to a method for instantly recovering, fermenting and utilizing rice and wheat straw as feed, and belongs to the technical field of straw resource utilization. Background technique [0002] With the large-scale development of the planting industry and the popularization of the use of clean energy in rural kitchens, farmers have lost the initiative to collect and utilize straw waste. A large amount of crop straw waste is incinerated after the harvest season. Manpower and material resources, the use of satellite weather monitoring, responsibility to the field and other technical and administrative means to strictly investigate the burning of straw, but it is still repeatedly banned, causing serious air pollution, and at the same time bringing safety hazards to traffic and civil aviation. [0003] The main reasons are as follows: [0004] 1. The use value of rice and wheat straw is not high, and it will affect the cultivation of nex...

AI Technical Summary

Problems solved by technology

[0004]1. The use value of rice and wheat straw is not high, and it will affect the cultivation of next season crops

Due to the widespread use of planting machinery and clean energy in rural areas, straw resources lose their original use value and are abandoned in the fields, hindering farmland re-cultivation; at the same time, crop straws are concentrated and produced in large quantities after grain harvesting, which cannot be recycled quickly, and its nutritional content is quickly lost. The value of feed is significantly reduced, which inhibits farmers' enthusiasm for straw recycling

[0005]2. There are few utilization methods of rice and wheat straws, large cost investment and complex technical requirements

The existing straw utilization methods mainly focus on concentrated industrial utilization methods such as straw power generation, board making, and gasification, which require large initial investment, high operating costs, and complicated technologies, which are not conducive to being accepted and used by the majority of farmers.

[0006]3. The production characteristics of rice and wheat straw are not conducive to the existing industrialized utilization

The existing straw utilization technology needs to ensure a long-term and stable supply of straw resources and low storage costs; however, straw production is relatively scattered, with low density, large volume, high collection, transportation, and storage costs, and strong seasonality, which is not conducive to Year-round utilization and low-cost utilization inhibit the enthusiasm of enterprises to purchase and utilize straw

[0007]4. There are difficulties in the utilization of rice and wheat straw as feed

Since rice and wheat straw are concentrated in the harvest season, if they cannot be harvested and utilized in time, the soluble sugar content will drop sharply in the first 3-5 days, and the nutritional value will drop rapidly, thereby reducing the feeding value sharply

[0008]These problems have seriously hindered the pace of resource utilization of rice and wheat straw
