棉花与大球盖菇两熟种植的系统生产力、经济效益及土壤肥力效应研究
Research on the system productivity,economic benefit and soil fertility impacts of double cropping of cotton and Stropharia rugosoannulata
摘要
Abstract
[Objective]To address the issues of idle field in winter and spring,low utilization efficiency of cotton straw,and declining profitability in cotton production in the Yellow River Basin,a cotton-Stropharia rugosoannulata double cropping system was proposed,which utilize crushed cotton straw for S.rugosoannulata cultivation in the winter fallow field,followed by S.rugosoannulata residue returning to field.The objective was to investigate the comprehensive effects of this system on productivity,economic benefit,and soil fertility,aiming to provide technical support for the green and sustainable development in the local cotton-growing region.[Methods]Field experiments were conducted from 2022 to 2024 in Linqing City,Shandong Province.Using monocropped spring cotton(MFC)and monocropped short-season cotton(MSC)as controls,the annual yield,economic returns,and soil nutrient content dynamics of two double cropping patterns,intercropping of spring cotton with S.rugosoannulata(FC+SR),short-season cotton followed by S.rugosoannulata in succession planting(SC+SR),were systematically compared.[Results]Compared with MFC treatment,the seed cotton yields of FC+SR and SC+SR treatments significantly decreased by 7.7%and 14.2%,respectively.However,by harvesting S.rugosoannulata(fresh yield:20.80-21.53 t·hm-2),the system's net profit was significantly increased to 216 700-244 100 yuan·hm-2,which was 43.3-48.8 times that of MFC treatment.The net profit of SC+SR pattern was 12.6%higher than that of the FC+SR pattern.Compared with monocropped cotton,the double cropping patterns combined with straw and S.rugosoannulata residue returning significantly increased the contents of alkali-hydrolyzable nitrogen,available phosphorus,and available potassium in the 0-20 cm,20-40 cm,and 40-60 cm soil layers.And the improvement effect of the SC+SR pattern was generally superior to that of FC+SR.[Conclusion]The cotton-S.rugosoannulata double cropping system is feasible in the Yellow River Basin,with the short-season cotton followed by S.rugosoannulata in succession planting(SC+SR)being the preferred choice.This pattern achieved the recycling of field straw resources and synergistic enhancement of economic benefits and soil fertility,serving as an effective pathway for promoting high-quality agricultural development in the cotton-growing regions of the Yellow River Basin.关键词
