摘要
针对黑龙江省西部地区鲜食玉米秸秆肥料化还田利用问题,以本地区主栽主推的鲜食玉米品种为材料,利用尼龙网袋法,开展鲜食玉米秸秆还田腐解规律研究,通过对不同还田时间、不同切碎长度秸秆腐解情况的测定,探索鲜食玉米秸秆全量还田效果,明确腐解规律,为鲜食玉米的生产和秸秆的绿肥还田利用提供技术支撑.结果表明,黑龙江省西部地区鲜食玉米收获期不同品种秸秆还田腐解率存在较大差异,收获时期是影响腐解率的重要因素,各品种腐解率随扎短长度的增加而降低.
Abstract
In In order to solve the problem of using fresh corn straw as fertilizer in the field in western Heilongjiang,a study was conducted on the decomposition of fresh corn straw using nylon net bag method using the main fresh corn varieties planted in the region as materials,the effect of fresh corn straw returning to field was studied by measuring the decomposed condition of straw with different returning time and different chopping length,it provides technical support for the production of fresh corn and the application of green manure.The results showed that there were significant differences in decomposition rates of fresh corn stalks among different varieties at harvest time in western Heilongjiang,the decomposition rate of all varieties decreased with the increase of the length of tie.
