不同灌水量和栽培方式对土壤养分及菊芋产量和品质的影响
Effects of different irrigation amounts and cultivation methods on soil nutrients,yield and quality of Jerusalem artichoke
摘要
Abstract
The field split zone experiments were conduct from 2021 to 2022.The three irrigation amounts were 3 750 m3·hm-2,4 500 m3·hm-2(W2),and 5 250 m3·hm 2(W3),respectively.The cultivation methods were ridge planting(B1)and flat planting(B2).The effects of different irrigation amounts and cultivation methods on the yield,quality,and soil nutrient content of Jerusalem artichoke in the desertification area of Hexi were studied.The results showed that with the increase of irrigation amount,the content of total nitrogen,avaiable nitrogen,total phosphorus,and available phosphorus in the 0～20 cm soil layer showed a downward trend while the content of a-vailable potassium first increased and then decreased.The W2B1 treatment performed the best.The plant height,stem diameter,number of tubers per plant,tuber mass per plant,and yield of Jerusalem artichoke treated with W2B1 were higher than other treatments,with increases of 1.94％～19.79％,2.71％～28.87％,8.22％～31.68％,12.22％～57.81％,and 12.31％～58.01％,respectively.The total sugar,reducing sugar,soluble sugar,and inulin content of Jerusalem artichoke treated with W1B1 were higher than those of other treatments,with increases of 7.25％～18.19％,1.35％～6.19％,4.20％～39.67％,and 7.58％～19.10％,respectively.The inulin content is in the order of W1B1＞W2B1＞W2B2＞W1B2＞W3B2＞W3B1.The results suggested that increasing irrigation was not conducive to the accumulation of inulin content in tubers.Under the same irrigation quota,ridge cultivation was more conducive to the accumulation of inulin in tubers than flat cultivation.Through principal component analysis,the comprehensive evalu-ation of the effects of different treatments on the yield and quality of Jerusalem artichoke as well as soil nutrient con-tent showed that the combination of 4 500 m3·hm-2 irrigation with ridge planting had the best effect,while the com-bination of 5 250 m3·hm-2 irrigation with flat planting had the worst effect.关键词
