营养元素配施对半夏产量和品质的影响
Effects of Nutrient Element Combination on the Growth and Quality of Pinellia ternata
摘要
Abstract
Objective:To study the effects of different nutrient element combinations on the yield and quality of Pinellia ternata.Methods:Under field conditions,six nutrient elements(nitrogen,phosphorus,potassium,cuprum,boron,molybdenum)and low,medium,and high concentrations were setup,the yield,dry matter rate,compliance rate of tuber diameter,as well as the contents of starch,soluble sugar,total protein,nucleosides,succinic acid,citric acid,and alkaloids in Pinellia ternata were determined.Results:Treatment No.6 resulted in the highest fresh yield(14 901.35 kg/hm2),which was significantly higher than other treatments(P<0.05).Treatment No.10 showed the highest dry matter rate(44.45%),while Treatment No.8 resulted in the highest tuber diameter compliance rate(77.82%).The highest starch content was observed in Treatment No.16(181.29 mg/g),the highest soluble sugar content in Treat-ment No.4(65.54 mg/g),and the highest total protein content in Treatment No.17(18.57 mg/g).The total nucleoside content ranged from 0.71 to 2.99 mg/g,the total succinic acid and citric acid content ranged from 0.98 to 1.82 mg/g,and the alkaloid content ranged from 0.46 to 1.50 mg/g.Conclusion:The application of urea(18.70 g/m2),calcium superphosphate(478.80 g/m2),potassium sulfate(31.05 g/m2),chelated copper(1 500-fold dilution,0.24 g/m2),sodium molybdate(750-fold dilution,0.48 g/m2)and disodium oc-taborate tetrahydrate(1 000-fold dilution,0.36 g/m2)result in a fresh yield of 14 901.35 kg/hm2.Regarding quality,high application rates of the six elements promote an increase in nucleoside components.High nitrogen and high boron conditions favor the accumulation of starch,total protein,and alkaloids.High potassium conditions promote the increase of soluble sugar content,while high molybdenum conditions enhance the contents of succinic acid and citric acid.关键词
