有机肥替代氮肥配施叶面肥对不同粒型水稻营养分配、产量及品质的影响
Effects of Replacing Nitrogen Fertilizer with Organic Fertilizer Combined with Foliar Fertilizer on Nutrient Allocation,Yield,and Quality of Different Grain Types Rice
摘要
Abstract
To clarify the effects of replacing nitrogen(N)fertilizer with organic fertilizer combined with foliar fertilizer on nutrient allocation,yield,and quality in different grain-types high-quality rice varieties,a field experiment was conducted using the long-grain type rice variety Xiushuixiang 1(L)and the round-grain type rice variety Zhehexang 2(R).Three treatments were set up:conventional fertilization(CK),40%N replaced by organic fertilizer(40%M),and 40%N replaced by organic fertilizer plus foliar fertilizer(40%ML).The response characteristics of N,phosphorus(P),and potassium(K)translocation,as well as yield and quality,to different N management strategies in the two grain types were investigated.The results showed that,compared with the round-grain variety,the long-grain variety had the highest N and P contents in leaves,along with the highest N,P,and K allocation ratios;the lowest N and K allocation ratios in stems;and the highest K content and K allocation ratio in panicles,but the lowest P content and the lowest N and P allocation ratios in panicles.In addition,organic fertilizer substitution significantly affected nutrient allocation in the two grain types.Compared with L-CK,leaf N content under L-40%M and L-40%ML increased significantly by 51.74%and 51.90%,respectively.Compared with R-CK,panicle N content under R-40%M and R-40%ML increased significantly by 36.65%and 35.19%,respectively.In terms of yield,the L-40%ML and R-40%ML treatments produced the highest yields,increasing by 6.10%and 4.26%over their respective controls.In terms of rice quality,compared with the control,both chalkiness degree and chalky grain rate of theL-40%ML and R-40%ML treatments were significantly reduced,the long-grain variety showed reductions of 13.64%and 16.67%,while the round-grain variety showed reductions of 29.03%and 25.00%,respectively.In conclusion,replacing 40%of N fertilizer with organic fertilizer combined with foliar fertilizer can optimize nutrient uptake and utilization in both grain-types high-quality rice varieties,achieving coordinated improvements in both yield and quality.This provides a feasible strategy for green and efficient production of high-quality rice.关键词
