我国施肥技术与施肥机械的研究现状及对策

Actuality and Measures of Fertilization Technology and Machinery in China

施用化肥直接关系着粮食安全与产量,落后机具与技术的现状会导致作物肥料吸收率低,进而影响粮食产量,也会加重农业对生态环境的污染。为此,分析了测土配方施肥、缓控释肥、变量施肥与灌溉施肥技术,以及变量施肥机械、种肥施肥机械、追肥施肥机械、液态施肥机与撒肥机的研究现状及其存在的问题,并提出了相应的对策与措施。

The application of chemical fertilizer directly links with safety and yields of foodstuff .The backward actuality of machinery and techniques in China not only causes the low absorptivity of fertilizer in crops which influences the yields in foodstuff , but also increases the agriculture pollution to environment .Therefore , the research actuality of the techniques of formula fertilization by soil testing , slow controlled release fertilizer , variable-rate fertilization and fertilization techniques of irrigation , variable-rate fertilization machinery , seed manure fertilizing machinery , topdressing fertilizer , liquid fertilization machinery and fertilizer spreading machines , and whose problems are analyzed in the article .Besides , the relevant improvement measures are put forward .
