通过各种培肥措施对改善土壤粘重,降低容重,提高土壤含水量均有一定效果。其中,深松起垄加秸秆对改善土壤粘重效果最好,降低土壤容重0.04g/cm~3。土壤含水量,0-5cm提高2.8-3.5个百分点;5-10cm提高1.7-2.1个百分点;10-15cm提高1.6-1.7百分点。
Through a variety of fertilizing measures to improve the soil viscosity, reduce bulk density, increase soil moisture have a certain effect. Among them, deep loose Ridge plus straw to improve the soil sticky best, reducing soil bulk density 0.04g / cm ~ 3. Soil water content, 0-5cm increased 2.8-3.5 percentage points; 5-10cm increased 1.7-2.1 percentage points; 10-15cm increased 1.6-1.7 percentage points.
