对间隔深耕打破浅位粘层加施作物秸草改良丘陵棕壤理化性状及增墒蓄水效果进行了试验。间隔40cm深耕60cm,每亩加秸草200kg,较对照土体容重减少0.12g/cm~3,总孔隙度增加5.53％,土壤含水量增加1.7％;深耕第2年测定,土壤有机质、全氮、速效磷、速效钾分别增加0.0066％、0.0044％、10.7ppm、14.5ppm。加草处理深耕40cm较深耕60cm小麦产量差异不显著,与深耕60cm、40cm、20cm不加草处理比较小麦产量差异极显著。
Experiments were carried out to study the physical and chemical properties of paddy soils improved by shallow plowing and the effects of increasing water storage and storage by breaking shallow superficial sticking layers and applying crop straw. The total porosity was increased by 5.53% and the soil moisture content increased by 1.7%. The soil organic matter and total nitrogen content , Available phosphorus, available potassium increased by 0.0066%, 0.0044%, 10.7ppm, 14.5ppm. There was no significant difference in the yield of 60 cm between deep-plowing and deep-plowing with 40 g of grass and 60 cm, 40 cm and 20 cm of deep-plowing without grass treatment.
