密度与肥料配比对小麦宁春52号产量及其构成因子的影响
Effects of Density and Fertilizer Ratio on Yield and Its Component Factors of Wheat Ningchun 52
摘要
Abstract
[Objective]The aim is to screen situable density and fertilizer ratio for wheat planting.[Method]three kinds of planting density and five kinds of fertilizer ratio were set, effects of density and fertilizer ratio on wheat Ningchun 52 was studied.[ Result] Leaf area index of the higher planting density (540 ×104 plants per hectare) was the highest between jointing stage and tillering stage , but in flagging stage, the highest leaf index was in the lower planting density (450 ×104 plants per hectare) and a higher fertilizer ratio(B4:N225 kg/hm2,P2O5225 kg/hm2,K2O 135 kg/hm2) can produce a higher leaf area index in every growth stage;The highest tiller formation rate was occurred in A2(495 ×104 plants per hectare) or B3(N 150 kg/hm2,P2O5300 kg/hm2, K2O 135 kg/hm2) ;A higher plangting density A3(540 ×104 plants per hectare) and a lower fertilizer ratio B1(N 150 kg/hm2,P2O5255 kg/hm2, K2O 0 kg/hm2) would be suitable for a higher yield demand for the wheat and a lower fertilization for high fertility soild.[Conclusion]The research can provide guide for sowing and fertilizing of wheat.关键词
