China should attach importance to agricultural equipment multifaceted sustainable development

A sustainable agriculture and water-saving irrigation technology and equipment problems . Of water scarcity . Water per year 30 billion m3, drought-hit area of ​​20 million hm2, the country has 80 million rural drinking water. Therefore, we must find a way out from the water , develop water-saving agriculture. Currently, the promotion of water-saving irrigation technology and equipment has matured, but water-saving irrigation equipment, there are some issues to be resolved. First , China's water-saving irrigation machines and mobile machine nozzle, joint form basically the same , you can choose range of small, rotating nozzle uneven wear . Wind nozzles, special nozzles to be research and development . Secondly, micro-irrigation technology in the domestic micro sprinklers , drippers , various forms dropper with fewer species . System complete with control equipment , filters, fertilizer , injectors, and other key technology node blockage need to overcome . Third , water-saving devices , "three" low level , but also to further improve standards.

Two sustainable agriculture and land conservation technology and equipment problems . Of land conservation imminent. According to statistics, currently expanding desertification area has reached 1,533,000 square kilometers , accounting for 15.9% of the land area . Erosion surface increase, 39% of the country's total area ; land quality declining arable land 59% of phosphorus deficiency , 23% potassium ,chemical sprayer 14% lack both phosphorus and potassium , 30% nitrogen deficiency province 's arable land , China low-yielding fields representing about 70% of arable land ; land resources severely damaged due to various human factors , derelict land total 200 million acres ; national grassland each year 30 million mu to 4000 mu degradation , desertification grassland (50%) ; 70 % arid and semi -arid grassland . Nearly 10 years , the national forest area decreased by 23 ? 1% , the agricultural ecological environment deterioration , reduced water storage capacity . Land pollution is worsening . From industrial "three wastes " pollution , contaminated land 6,700,000 hm2; affected by acid rain harm agriculture 2,660,000 hm2; national industrial solid waste and municipal solid waste a total area of ​​5.36 million hm2, which accounted for farmland 40000 hm2. As well as from the pollution of agriculture itself , mainly excessive application of pesticides , resulting in changes in soil properties , soil fertility decline and so on.

To this end , research and development of grass and trees terracing of special machinery and equipment development project is imminent. Promotion and development of new ultra-low- volume spraying ( powder ) device , so that the liquid droplet diameter down to 15μm ~ 75μm, reduce pesticide use , improve the efficacy and control effect ; development of new agricultural film recycling machinery and equipment , prevention of pollution of agricultural plastic film .

Three dimensional cultivation of sustainable agriculture and technical equipment problems . Stereoscopic three-dimensional cultivation of agricultural cultivation , including three-dimensional cultivation, water power sprayer livestock integration , planting combination , courtyard economy mode. Machinery and equipment in this regard very little mechanization intercropping is a major problem , this is not caused by power machine and supporting tools ; farming raise land farming techniques and equipment developed much, much less be able to use ; courtyard economy is on the rise among , there is no typical mechanical equipment developed . Stereoscopic both sustainable agriculture cultivation technology and equipment needed for development , but also the "three rural" market need to develop products .
