于1991~1994年在坡梁旱砂地栗钙土上进行定位试验。结果表明,有机无机培肥后可使土壤总有机C、HA和FA含量明显增加,土壤重组C及复合量增大,酶活性增强;毛管孔隙与田间持水量(θω%)各有机肥处理较N0P0处理分别增加33~57%和21~39%;0.01~0.25mm微团聚体含量、团聚水平与团聚度相应提高。有机无机肥配施的莜麦增产374.8~486.3%,降水利用率由0.92kg/mm·hm2提高到4.39~5.42kg/mm·hm2。
In 1991 ~ 1994 in the slope of the chestnut soil on the chestnut soil positioning test. The results showed that organic and inorganic fertilizers could significantly increase the content of soil total organic C, HA and FA, and increase the amount of C and the content of soil recombinants, and increase the enzyme activity. The ratio of capillary porosity and field water holding capacity (θω%) N0P0 treatment increased by 3577% and 21 ~ 39%, respectively. The content of microagglutination of 0.01 ~ 0.25mm increased agglomeration level and agglomeration. Oats combined with organic and inorganic fertilizers increased yields by 374.8 ~ 486.3% and precipitation utilization efficiency increased from 0.92 kg / mm · hm2 to 4.39 ~ 5.42 kg / mm · hm2.
