露地辣椒生产固碳增活全程施肥方案
Fertilization Schemes for Soil Carbon Storage and Microbial Activity Enhancement of Open Field Pepper Production
摘要
Abstract
Hebei open-field pepper cultivation has a long history,but extensive nutrient management has led to soil organic matter depletion,poor plant stress resistance and frequent continuous cropping obstacles.The fertilization strategy used in this article for promoting soil carbon sequestration and bio-activation of open-field pepper production integrated three technical contents:balanced reduction of fertilizer nutrients,organic substitution for promoting carbon sequestration and nutrient efficiency,and drip irrigation with beneficial microbes for soil bio-activation.Based on this strategy,a whole-process fertilization solution,including the recommendation of fertilizer nutrients,multi-source combined application of organic fertilizer and coordinated operation of dripping microbial agents and soluble fertilizer,had been developed for improving soil quality and protect cultivated land in traditional open-field pepper production areas.By comparing the application effects of four carbon sequestration technology models,it was found that the yield increase effect of organic material pepper with diversified sources of basal application was better than that of single organic material.The optimal model was cow manure compost+straw biochar,or cow manure compost+corn straw+straw biochar technology model(straw returning conditions).It helped to promote the nutrient management of growers from blind and extensive to reasonable and accurate.Prospects for the application of technology was broad.关键词
