Microfloral activity in worm may have an important effect on soil crumb structure .
蚯蚓類中微生物群落活性對土壤團粒結構可起重要作用。
The result indicated that straw mulching could increase soil porosity by 2 . 88 % - 5 . 76 % , reduce soil bulk density by 1 . 86 % - 3 . 73 % and the content of soil water with straw mulching was higher than that with no straw mulching treatment ( ck1 ) at different growth stage , improve water - stable aggregate ; and increase soil organic matter , available n , available p , available k , improve soil perviousness and soil retention of water and fertipzer
研究結果表明，與對照ck1 ，相比，秸稈覆蓋可使土壤總孔隙度增加2 . 88 % ~ 5 . 76 % ，土壤容重降低1 . 86 % ~ 3 . 73 % ，并且各生育期覆蓋處理的土城含水量均比對照高，并且秸稈覆蓋還田對促進土壤團粒結構形成具有較大作用，改善了土坡通透性和保水保肥性；同時秸稈覆蓋還田使土壤有機質、全氮、速效氮、速效磷、速效鉀得到明顯提高，從而培肥地力。
2 . the structure of purple soil is meporated by sabaigrass . when contrast to bare land treatment and natural wild grassland treatment we knew that sabaigrass treatment and grass tree sopd plating treatment reduced soil bulk density , enhanced soil capillary porosity , non - capillary porosity and porosity ratio , decreased soil sand grain content , enhanced soil clay grain and silt grain content so as to reduced the dispersal degree of soil , improved the aggregate capacity of soil , increased the amount of soil aggregate structure , meporated the water permeabipty of soil , accelerated the form of good soil structure
龍須草能改善紫色土的土壤結構龍須草純種植被和林草立體種植植被能不同程度地降低土壤容重，減少土壤砂粒含量，增加土壤的毛管孔隙度、非毛管孔隙度和孔隙比，以及增加粉粒含量，從而降低土壤分散度，提高土壤團聚性，增加土壤團粒結構數量，改善土壤的透水性，促進良好土壤結構的形成，最終提高土壤的蓄水保肥性能，增強土壤的抗蝕性和抗沖性。
