subject: China Should Attach Importance To Various Sustainable Development Of Agricultural Equipment [print this page] First, our equipment and issues of sustainable agriculture
1 sustainable agriculture and water-saving irrigation technical equipment issues. Scarcity of water resources. Water 30 billion per year m3, drought area of 20 million hm2, the country has 80 million rural drinking water. Therefore, we must find the way from the water, develop water-saving agriculture. At present, the promotion of water-saving irrigation technology and equipment have been mature, but the water-saving irrigation equipment, there are still some issues to be resolved. First of all, our water-saving irrigation machines and mobile machine nozzle,
Connector Basically the same form, select a small range nozzle rotation uneven, easy to wear. Wind nozzle, a special nozzle to be research and development. Second, the micro-irrigation technology in the home-made micro-sprinklers, drippers, various forms of dropper with fewer species. System complete with control equipment
Filter , Fertilization device, nozzle blockage and other key technology nodes need to overcome. Third, the water-saving equipment, "three" low level, also need to further improve standards.
2 technical equipment for sustainable agriculture and land conservation issues. China's land conservation is urgent. According to statistics, expanding desertification area has reached 1.533 million square kilometers, accounting for 15.9% of land area. Increase soil erosion area, accounting for 39% of the area; declining land quality, 59% of arable land in the deficiency, 23% potassium, 14% of phosphorus and potassium all missing, 30% of the province's arable land deficient in nitrogen, in low-yielding fields account for about 70% of existing arable land; land resources severely damaged, due to various human factors, waste accumulated 200 million acres of land; National Grassland degradation of 3000 acres per year to 4000 mu, desertification, grassland 50%; 70 % for the arid and semi-arid grassland. Over the past 10 years, the national forest area by 23? 1% of the agricultural ecological environmental degradation, reduced water storage capacity. Land pollution is worsening. From the industrial "three wastes" pollution, contaminated land 6.7 million hm2; by acid rain and harm the agricultural 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. There are pollution from agriculture itself, mainly the excessive application of pesticides, leading to changes in soil properties, soil fertility decline and so on.
This end, research and development of grass and trees terracing of special machinery and equipment development projects imminent. Promotion and development of new ultra-low volume spray (powder) devices for the liquid droplet diameter down to 15 m ~ 75 m, lower pesticide use, improve the efficacy and the control effect; development of new agricultural plastic film and recovery of machinery and equipment, control of agricultural plastic film pollution.
3-dimensional culture of sustainable agriculture, technical equipment and issues. Three-dimensional cultivation of agricultural cultivation, including three-dimensional, three-dimensional culture, combining agriculture and animal husbandry, planting and breeding combination of courtyard economy mode. This little mechanical device, intercropping is mechanization a major problem, cause this is not power machine and supporting tools; farming land to support development of small farming technology and equipment, can use even less; courtyard economy is on the rise among , there is no typical mechanical equipment developed. Three-dimensional culture of technical equipment is needed for sustainable agricultural development, but also "three rural" market need product development.
