| 摘 要： | 应用土壤调理剂“免深耕”3000、3750和4500g／hm^2在稻田上进行免耕效应试验，结果显示，施用不同用量的“免深耕”比对照增产稻谷967．5～1237．5kg／hm^2，增产极显著，以3750g／hm^2的用量处理增产效果最好，产投比达2．67。稻田施用“免深耕”后，孔隙度提高3．68％～4．41％（绝对值），土壤的物理结构得到改善，土质变得疏松。

| Abstract: | The trial of soil conditioner Mianshengeng, with the applications of 3000g, 3750g, and 4500 g / hm^2, in paddy field for no -tillage rice cultivation was carried out. The results showed that compared to the check, the treatment significantly out yielded by 967.5 to 1237.5 kg / hm^2, of which the most obvious efficiency was the application of 3750 g / hm^2 with 2.67 of output / input ratio. The soil crevice was raised by 3. 68%-4.41% of absolute value and the structure of the soil, which get more loosen, were improved. |
