【摘要】 小麦是我国的主要粮食作物,施肥播种装置的精准水平对小麦产量有很大的影响。为提升我国小麦施肥播种机的性能,对国内外小麦施肥播种装置的发展现状进行分析,重点分析开沟器、排肥排种器及精播系统三个核心部件的国内外发展现状,为解决还田秸秆较多开沟器易产生堵塞问题、根据土壤性质实时变量排肥和精量播种提供参考。同时,围绕小麦规模化种植、农艺农信结合、播种效率提升等方面提出一些建议。更多还原

【Abstract】 Wheat is the main grain crop in China. The precision level of fertilizer and sowing device has a great influence on wheat yield. In order to improve the performance of Wheat Fertilizer seeder in China, the development status of Wheat Fertilizer seeder at home and abroad was analyzed. And then the development status of three core components of ditcher, fertilizer metering device and precision seeding system at home and abroad was emphatically analyzed. It can provide a reference for solving the problem of clogging easily caused by ditcher with more straw returning to field, real-time variable fertilization according to soil properties, and precision sowing. In addition, some suggestions are put forward on large-scale wheat planting, agriculture and agricultural information technology, the improvement of sowing efficiency.更多还原
