【摘要】 本试验利用地产混合蛭石直接施入土壤,观察蛭石的不同用量对土壤主要物理性状,土壤持水力、土壤水分常数,根区速效养分,作物生理功能及产量等综合影响的结果表明:每放施用地产混合蛭石240kg,120kg与对照比较,不仅分别增产15.5%、13.43%,而且还可改善种子品质。更多还原

【Abstract】 The paper deals with the effects of local vermiculite on soil. Theexperiments are planned to observe the changes of soil-crop factors, suchas soil physical behavior, moisture constant, moisture capacity, quick-actingfertilizer in root zone, crop physiological function, yield etc., afterwhen the vermiculite was used. The results obtained show that the vermi-culites applied into soil by 240 kg/mu (Chinese), 120 Kg/mu not onlyincrease the crop yield by 15.5%, 13.43% respectively, but also improvethe seed quality.更多还原
