摘要:
通过对白浆土土壤含水量、容重、硬度及对大豆产量的测定分析，研究四段犁改土技术对土壤物理性状、水分利用率及大豆产量的影响。结果表明：经过一个作物生育期后，四段式根茬心土混合犁深松与对照相比，土壤30~40 cm土层含水量增加2578%、容重降低2047%、硬度降低4060%，0~50 cm土层含水量平均增加1123%、容重降低690%。大豆产量提高3338%，差异达到极显著水平。
Abstract:
According to the mensuration and analysis of soil moisture，soil bulk density,soil hardness and the yield,the effects of a four-stage stubs subsoil mixing plough on planosol physical characters,water use efficiency and soybean yield were studiedThe results indicated:Through a growth period of crop，a four-stage stubs subsoil mixing plough improving the soil treatment compared with the CK:in 30~40 cm soil layer,the soil water content increased by 2578%,soil bulk density was reduced by 2047%,the hardness was reduced by 4060%In 0~50 cm soil layer，the average water content increased 1123%，the bulk density was reduced by 690%The soybean yield was improved by 3338%,the discrepancy reached a very significant level
