菌渣还田对中国北方农牧交错带农田土壤生境的影响
Soil habitats are affected by fungal waste recycling on farmland in agro-pastoral ecotone in northern China
[目的]农牧交错带是我国北方重要的生态屏障和粮食安全屏障。由于中国北方地区由于频繁的地表扰动导致土壤肥力较低,因此存在活跃土壤性质的潜力。探究菌渣还田对土壤性质的影响,有助于在生产力较弱的地区减少化肥的使用,最终实现绿色农业。[方法]试验材料为废弃菌渣和经过发酵有机肥料并达到完全分解的状态(鸡粪,牛粪)。在还田之前,发酵后的真菌残留物被装进便于运输的包装袋(每包 30 个)。2019 年春至期间,废弃真菌残留物均匀分布在土壤表面。还使用旋转耕作机…查看全部>>
[Objective]As part of the ecological barrier and food security,the agro-pastoral ecotone is vital in the northern China.Since soil fertility in northern China is low due to frequent surface disturbances,there is the potential to actively.soil properties.Exploring the effect of fungal residue return on soil properties will help reduce the fertilizer used in areas with weak productivity and ultimately achieve green agriculture.[Method]The test materials were w…查看全部>>
