subject: China's Grassland Animal Husbandry Techniques And Equipment Status And Development Trend [print this page] 50's to 70's, animal husbandry machinery industry started and formed a forage harvester system. After the Third Plenary Session of the Eleventh Party, in the introduction and assimilation, based on preliminary construction and improvement of grassland, forage banku for storing and preparation and processing, livestock feeding and management, animal husbandry machinery acquisition and processing system. 80's animal feed industry and farming equipment for a larger development with the development of aquaculture. However, the economic development in pastoral areas due to constraints and changes in production management systems, so in recent years, the development of grassland animal husbandry machinery to certain effects. Currently, the main enterprises Animal Husbandry Machinery 55, 1.8 million workers. Mechanical output of livestock products 1998 222 000 (sets), industrial output value of 540 million yuan, respectively, compared with growth in 1997 -19.3% and -23.8%. 3 years from 1996 to 1998 showed a decreasing trend of product output. Shows, livestock machinery production will be difficult to achieve, "Ninth Five-Year Plan" 350,000 units / year target.
1.1 grasslands and improved technologies and equipment
80 early domestic development and production of the loose soil, fertilizer sowing machine and drill and other grassland farming equipment, but use is limited. Most of grassland in the arid and semi-arid state, for grassland improvement, should avoid all large area of grassland plowing caused by desertification. Therefore, these areas are necessary to promote conservation tillage. Sub-surface potential of the domestic research pine grassland system consists of a set of potential improvement of machinery loose plow, backfill suppression devices and the composition of deep fertilizer drill, operating in vegetation destruction, to be completed by the underlying potential of grassland vegetation in pine, deep fertilization and planting grass seed the whole process, by further improving the great market potential. Mixed grass hay yield can high and stable, great promotional value, but still lack such a planter with the domestic. Therefore, research for a grass seeder is a priority.
Manually China Seed collection, no special harvesting machine. Hohhot, animal husbandry machines, developed by a small comb brush grass seeds collected directly threshing machine, picking grass seeds directly in the field, pasture or grazing can banku for storing, use a good effect. Sowing the Seed requests to two or more, export more special requirements. China's lack of advanced processing equipment, Pin Seed sold below the rank of general is only 3, quality of export is very much affected. At present, China grass seed processing machinery in the initial stage, while 80 developed grass seed processing equipment, its processing capacity and performance have been unable to meet the market requirements. Therefore, the study produced a dry, selection, coating, pelleting and other deep-processing capacity of the larger advanced equipment has become a large-scale construction and improved grassland needed.
1.2 forage banku for storing technical equipment
Grassland animal husbandry developed various production processes have largely mechanized. The United States each with a set of 60 hectares of grass cutting, brush, bundle, stack, transport equipment. China's average of 5.5 thousand hectares of usable grassland have a lawn mower, and a serious lack of ancillary equipment, forage banku for storing the amount of mechanical work is not yet to 5%. Traction-type mower, grass machine horizontal brush is still a lot of applications in the pastoral areas, but the old models, need to be replaced. Square bale baler to pick up than the widely applied, but the bundles is low. Big round bale tie machine volume shipment weight excessive inconvenience. Of Forage banku for storing machinery and most advanced level of manufacturing quality gap is the poor, poor reliability. Successful research needs of the market in recent years, the small round bale bundle volume prototype, with a round bundle wrapped film machine has come out. The newly developed properties and quality of forage harvesting machines have improved significantly. The equipment will improve efficiency and quality of forage banku for storing important role to play.
1.3 forage preparation and processing technology and equipment
Domestic development and production since the founding of various models of chaff cutter, feed mill and forage chopper, although processing is extensive, but still play an active role in animal husbandry. With the rapid development of animal husbandry, the number of silage and ammoniated straw doubled, but the domestic processing technology and equipment relevant research has lagged behind. Chopper machine productivity and machine efficiency are low. The early 80s designed by alkaline conditioning machines, are not widely adopted. Developed in recent years, chemical treatment of straw unit, the structure of its processing technology and equipment have a breakthrough, make various straw by mechanical processing and composite processing of high quality roughage. Should pay close attention to the development include a variety of microbial treatment processing technology and equipment, and develop and produce high-quality, high forage chopper.
