含碳有机肥对棉花养分吸收、产量及土壤养分含量的影响
Effects of carbon-containing organic fertilizer on nutrient uptake,cotton yield,and soil nutrient content
摘要
Abstract
[Objective]This research aimed to study the effects of different amounts of carbon-containing organic fertilizer on cotton biomass,nutrient accumulation,yield,and soil nutrient content to provide a reference for local cotton production.[Methods]From 2022 to 2023,field experiments were conducted in Wusu City,Tacheng Prefecture,Xinjiang.Six treatments were set up:no fertilization(CK),no application of carbon-containing organic fertilizer(C0),and application of carbon-containing organic fertilizer at 400 kg·hm-2,800 kg·hm-2,1 200 kg·hm-2,and 1 600 kg·hm-2 throughout the cotton growth period(referred to as C400,C800,C1200,C1 600,respectively).The effects of different amounts of carbon-containing organic fertilizer on the aboveground dry matter mass;accumulation and distribution of nitrogen,phosphorus,and potassium of cotton;yield;and soil nutrient content were analyzed.[Results]From 2022 to 2023,the dry matter mass,the accumulation of nitrogen,phosphorus,and potassium of cotton straw,fiber,cottonseed,and aboveground parts;and seed cotton yield all showed an overall upward trend with the increase of carbon-containing organic fertilizer application.The proportion of dry matter mass in fiber under C1600 treatment was higher than that in the other treatments.CK treatment exhibited the lowest proportion of nitrogen accumulation in straw and fiber but the highest proportion of nitrogen accumulation in cottonseed.Compared with C0 treatment,the application of carbon-containing organic fertilizer showed no obvious effect on the proportion of phosphorus and potassium accumulation in various aboveground parts of cotton.The seed cotton yield under C1600 treatment was highest,significantly increasing by 53.79％-83.34％and 8.95％-11.77％,respectively,compared with CK and C0 treatments.After harvesting cotton in 2023,the contents of organic carbon,nitrate nitrogen,ammonium nitrogen,available phosphorus,and available potassium in the 0-20 cm soil layer,as well as the content of available potassium in the 20-40 cm soil layer,all showed an upward trend with the increasing application rate of carbon-containing organic fertilizer.[Conclusion]Under the conditions of this experiment,the application of 1 600 kg·hm-2 carbon-containing organic fertilizer is beneficial for increasing soil nutrient content,promoting cotton's uptake of nitrogen,phosphorus,and potassium;increasing cotton aboveground dry matter mass;and achieving the highest seed cotton yield.关键词
