Crop pests in biological disasters and hazards are restricting agricultural high quality, efficient and sustainable development of agriculture is a major obstacle. Our perennial grass pest rat, harm occurred in an area 233 million hm2 ~ 2? 67 亿 hm2. China's annual application of a variety of chemical pesticides more than 70 million tons. One hand to play an important role in protecting agricultural production, the other on the environment and ecosystems negative negative effects. Thus, according to local conditions, rational use of chemical control, biological control, physical control and other measures to achieve economic, safe and effective pest control purposes hazards grass rat is particularly important. However, China's crop protection machinery products technical level, the majority of manufacturing quality of similar products equivalent to only 60 years to 70 years level. At present, China good quality motorized hand sprayer and plant protection machinery service life of similar foreign products is only 1/2. Mobile plant protection equipment nozzle drip severe degree of atomization not up to standard requirements. Large plant protection machinery advanced technology, such as aircraft and medium-sized agricultural tractor or towed hanging low volume boom tree sprayer, etc., the market demand urgent.
Agricultural and agronomic combination is not close.
Mechanical transplanting agronomy, requires efficient and reliable equipment and planting seedlings and transplanting its supporting farming equipment. Precision Drill now and transplanting seedlings disc machines are not mature enough to reach agronomic performance requirements. Two facilities for agricultural equipment products in variety and quantity do not meet their development. A large number of needs such as greenhouse film roll motor and sunroof open and close, shade nets Curtain motor, there is no domestic stereotypes specific products. Again, fewer varieties of greenhouse special heating equipment, incomplete specifications, dehumidification and fill light device is basically empty. Seedling tray planter with a small prototype, is not mature enough. Commonly used greenhouse soil moisture and carbon dioxide concentration sensor is not reliable, economical and practical products. Fog machine is not yet developed and so on. 3 Some of the facilities of agricultural equipment technical performance and quality issues seriously. Such as water-saving irrigation, irrigation, and the performance and reliability of the transition with similar foreign advanced products have a big gap, adjustable proportion of fertilizer pump does not pass. Domestic wet curtain are paper-core, long time easy to use moss, dirt contamination, affecting over air flow and cooling effect. Galvanized steel frames are used, corrosion resistance is not strong.
