- 摘要:
- 通过测土配方施肥与常规经验施肥比较的方法, 研究测土配方施肥的增产效果, 结果表明:测土配方施肥较空白增产178.7 kg/ 667m2 , 增产比率达50 %, 增效231.15 元/ 667m2 , 较常规施肥增产 30 .2 kg/667m2 , 增产比率达6 .3 %, 增效39.90 元/ 667m2 ;通过测定分析, 水稻对土壤养分的依存率为70 .7 %;秋收实际水稻单产与目标产量进行比较, 偏低13.8 kg , 目标产量吻合度为97 .5%。
- Abstract:
- Compared with the reg ular fer tiliza tion , the increasing effect of fo rmula fe rtilizatio n by soil testing wa s investig ated.The results showed that in com parison w ith co ntro l and regula r plots , rice yie ld in plots where fo rmula fertilizatio n by soil testing wa s applied, increased 178 kg/ 667m2 and 30 .2 kg/ 667m2 , co rre sponding to 50%, 6 .3 % o f inc reasing rate , and the ne t income wa s enhanced 231.15 yuan/ 667m2 , 39 .90 y uan/667m2 , respectively .Throug h determinating analysis, w e found that the dependent rate of rice on nutrient wa s 70.7 %.The rice y ield o btained a t harvest was low er 13.8 kg than that o f e xpected yield , the identical degr ee reached 97 .5 %.
