Abstract:

Provide scientific ecological planting and fertilization scheme for the cultivation of Alismaorientale(Sam.)Juzep.,and explore the effects of combined application of biological organic fertilizer and inorganic fertilizer on the agronomic properties and yield of A. orientale.In this study,the "3414" experimental design was used to investigate and analyze 13 agronomic characters and yield of A. orientale.It was found that organic fertilizer could significantly increase the number of blades;the combined application of organic fertilizer and chemical fertilizer can promote the growth of leaves and tuber expansion,and significantly improve the yield.The aboveground agronomic characters of A. orientale treated with 4(X2Y0Z2),such as leaf number,leaf width,leaf dry weight and plant height,performed best.The agronomic characters of the underground part of A. orientale treated with 14(X2Y1Z1)were more,such as fresh and dry weight of tubers,width and length of tubers,and the highest yield was 2 386 kg/ha.Through cluster analysis,it was found that the combined application of organic and inorganic fertilizers mainly affected the fresh and dry weight,yield,tuber width,tuber height,leaf length and leaf width of A. orientale.It was found that the yield and tuber width could be divided into the same kind of indicators,and there was a very significant positive correlation between them,with a correlation coefficient of 0.97.Therefore,the tuber width of A. orientale can be selected as a main agronomic character index for predicting yield and seed selection.Through the comprehensive evaluation of grey correlation degree and DTOPSIS Method,the best treatment is X2Y1Z1, that is bio organic fertilizer 150 kg/ha,urea 420 kg/ha, calcium super phosphate 200 kg/ha, potassium sulfate (K2SO4≥51.0%) 240 kg/ha, zinc sulfate(ZnSO4·7H2O)7.5 kg/ha, boric acid(H3BO3) 9.5 kg/ha, ammonium molybdate((NH4)6Mo7O24·4H2O)0.075 kg/ha.Based on the results of this study,the combined application of organic fertilizer and inorganic fertilizer can effectively promote the growth of A.orientale and increase it’s yield.
