Effects of Transplanting Date and Density on Dry Matter Production and Yield of Alisma plantago-aquatica
摘要
Abstract
In order to investigate the effects of transplanting date and density on the standardized cultivation of Alisma plantago-aquatica,a field experiment was carried out in Qiwangshan Town,Xingwen County,Yibin City in 2021.Factor 1 was transplanting date(X):August 17(X1),August 27(X2),September 6(X3),and Factor 2 was transplanting density(Y):120 000 plants/hm2(Y1),135 000 plants/hm2(Y2),150 000 plants/hm2(Y3).Dry matter accumulation and yield during the growth period were measured.The results showed that transplanting date and density had significant or very significant regulatory effects on dry matter accumulation and yield formation of Alisma plantago-aquatica at different stages.With the postponement of the transplanting date and the increase in density,the dry matter weight and yield of Alisma plantago-aquatica increased initially and then decreased.In the early growth stage,the dry matter accumulation of Alisma plantago-aquatica was better under X1 treatment,while in the middle and later stages,the dry matter accumulation of each organ was higher and the yield was better under X2 treatment.Under the density treatment,the material production of each organ was optimal at Y2 treatment,which is 135 000 plants/hm2.Overall,the highest yield of Alisma plantago-aquatica was achieved with a combination of transplanting on August 27 at a density of 135 000 plants/hm2.关键词
