有机液体肥替代化肥对棉花农艺性状及养分含量的影响
The effect of organic liquid fertilizer replacing chemical fertilizer on cotton agronomic traits and nutrient content
摘要
Abstract
To investigate the effects of replacing chemical fertilizers with organic liquid fertilizers on the growth,nutrient content,and seed cotton yield of drip-irrigated cotton in extremely arid regions,a single-factor randomized block design was employed.The study examined effects in cotton growth,nutrient content,and seed cotton yield resulting from the replacement of chemical fertilizers with organic liquid fertilizers at different substitution rates(T1:0%,T2:15%,T3:30%,T4:45%).The results indicated that replacing chemical fertilizers with organic liquid fertilizers increased the total nitrogen,total phosphorus,and total potassium content in all cotton organs.Throughout the entire growth period,the total nitrogen content in various cotton organs followed the order:bud∕flower∕boll>leaf>stem>root>lint;phosphorus uptake by the reproductive organs(buds∕flowers∕bolls)tended to be stable,with ranges of 6.33-6.67 g·kg-1,5.79-8.30 g·kg-1,and 5.53-5.68 g·kg-1,respectively;total potassium content across organs followed the order:stem>leaf>buds∕flowers∕bolls>root>lint.Considering the total fertilizer input,when the replacement rate of organic liquid fertilizer was 30%,cotton plant height,stem diameter,and SPAD values were highest.The seed cotton yield of the T3 treatment increased by 34.0%and 0.7%compared to the control(CK)without fertilization and the T1 treatment with chemical fertilizer alone,respectively;Correlation analysis indicated that the dry weight and total nitrogen content of cotton vegetative organs were significantly positively correlated with seed cotton yield,suggesting that liquid organic fertilizer promoted the growth of vegetative organs and nitrogen accumulation,thereby increasing seed cotton yield.Therefore,considering current production conditions,replacing 30%of chemical fertilizers with organic liquid fertilizer-specifically 280 kg·hm-2 of nitrogen from chemical fertilizers and 120 kg·hm-2 from organic liquid fertilizer-is recommended as the Alar local nitrogen fertilizer application scheme,as it can achieve both increased cotton yields and reduced chemical fertilizer use.关键词
