蚯蚓粪及其废弃栽培基质还田对陕北山地苹果生产和土壤肥力的影响
Effects of returning wormcast and its discarded cultivation substrate to field on mountainous apple production and soil fertility in Northern Shaanxi
摘要
Abstract
A field experiment was conducted to investigate the effects of applying wormcast and its waste cultivation substrate on apple yield,quality,and soil fertility in mountainous apple orchards in Northern Shaanxi.The experiment included three treatments:application of chemical fertilizer alone(CF),partial substitution of chemical fertilizer with discarded wormcast substrate(SWS),and partial substitution of chemical fertilizer with wormcast(SWC).The results showed that,compared to CF,the SWS and SWC treatments significantly increased apple yield by 14.4%and 20.1%,respectively,and significantly enhanced the contents of vitamin C and soluble sugars,increased the sugar-acid ratio,and reduced the titratable acid content in the apples.Furthermore,both organic substitution treatments significantly improved soil properties,including increases in soil organic matter,total nitrogen,available phosphorus,available potassium,and soil water content.The effect of wormcast(SWC)was superior to that of the discarded wormcast cultivation substrate(SWS),while the substitution of the discarded wormcast cultivation substrate showed unique advantages in terms of cost control and waste recycling.In conclusion,the substitution of wormcast or its discarded cultivation substrate are effective measures for enhancing soil fertility,apple yield and quality in mountainous orchards.It holds significant practical importance for promoting the sustainable development of the apple industry in Northern Shaanxi and facilitating the resource utilization of agricultural waste.关键词
