控失肥在水稻栽培中的节本增效分析

Cost-saving and Benefit-increasing Analysis of Controlled Fertilizer Loss in Rice Field

控失肥是一种吸附和网捕住N、P、K等养分,达到控制养分迁移、流失的新型肥料。通过开展控失肥在水稻栽培中的节本增效分析,结果表明:(1)控失肥的养分释放缓慢,肥效期长,肥料利用率高;(2)水稻后期植株健壮,籽粒饱满,结实率高,产量高。

Controlled loss fertilizer is a new kind of fertilizer which can absorb N,P,K and trap them in a net to con⁃trol the migration and loss of nutrients.By carrying out the analysis of cost-saving and efficiency-increasing in the field of controlling loss of fertilizer in rice cultivation,the results showed that:(1)the release of nutrients was slow,the fertilizer effective period was long,and the fertilizer utilization rate was high;(2)the plant was strong,the grain was full,the setting rate was high and the yield was good in the late stage of rice.
