化肥减量配施有机肥对春作马铃薯产量的影响
Effect of Reduced Chemical Fertilizer Plus Organic Fertilizer on Spring Potato Yield
摘要
Abstract
Reducing chemical fertilizer with addition of organic fertilizer is one of the important approaches to complement the reduction of chemical fertilizer application for better economic benefits.To investigate the effect of reducing chemical fertilizers and applying organic fertilizers on potato yield in high-altitude areas during spring planting,from February to Oc-tober 2023,in the potato production area of Liushao Township,Xundian County,Yunnan Province,China,Qingshu NO.9 was used as the experimental material.The field experiment adopted 11 different fertilization treatments,and set convention-al fertilization(25%potato special fertilizer 3 000 kg/hm2+farmyardmanure 15 000 kg/hm2)as the control.Conventional fertilization was reduced by 10%-50%combined with organic fertilizer,and the effect of chemical fertilizer reduction com-bined with organic fertilizer on spring potato yield in high altitude area was discussed.The results showed that the yield of the treatment with 10%-40%reduction in fertilizer and application of organic fertilizer was higher than that of the conven-tional treatment.Among them,the recommended fertilization(urea 522 kg/hm2,calcium superphosphate 1 125 kg/hm2,potassium sulfate 634.65 kg/hm2)+farm manure 22 500 kg/hm2 and 15 000 kg/hm2 treatments had the best yield and economic benefits,with potato yield increased by 16.6%and 16.2%,and economic benefits increased by 22.3%and 24.0%,respectively.When the maximum application amount of farmyard manure is 22 500 kg/hm2,it is recommended to reduce fertilization by 10%,resulting in an increase of 14.8%in yield and 20.6%in economic benefits.Compared with the conventional fertilization method,reducing the amount of chemical fertilizer by 10%and applying organic fertilizer can sig-nificantly improve the yield and economic benefits.This fertilization model is suitable for the nutrition management of spring cropping potato in high altitude area of Yunnan Province.关键词
