土壤干容重,soil dry bulk density
1)soil dry bulk density土壤干容重
1.The results indicated that tillage soil water infiltration capacity has larger changes in agricultural production cycle,with the change of soil water content from high to low water content;soil dry bulk density showed a trend of increase and soil water infiltration capacity showed a trend of decrease;in the period of crop .试验结果表明:耕作土壤的入渗能力在农业生产周期内变化较大;耕作土壤由高含水量到低含水量的变化过程中,土壤干容重呈增大趋势,土壤入渗能力呈减小趋势;作物生育期内,耕作土壤入渗能力衰减主要是由于土壤结构的变化所导致的。
