| 摘 要： | 对玉米扣半留茬播种与三犁川播种方法进行了比较研究。结果表明,扣半留茬播种比三犁川播种增产达990.0kg/hm2,增收节支达1488.0元/hm2,土壤含水量提高0.9～1.0个百分点;出苗率提高9.5个百分点。同时,扣半留茬播种能降低水蚀发生点数,通过根茬保留在垄台上,也能大大降低风蚀的危害性,是具有推广价值的保护性耕作技术。 |
| 关 键 词： | 玉米 扣半留茬播种 产量 产值 |

| Abstract: | The comparison study between conservation tillage sowing with half ridge removed and stubble reserved and traditional sowing of maize were carried out.Results showed that conservation tillage sowing increased the yield by 990.0 kg/hm2,income by 1488.0 yuan/hm2,soil water content by 0.9%~1.0% and emergence rate by 9.5% compared to conventional sowing.Conservation tillage sowing was an excellent protective tillage method in preventing water loss and soil erosion. |
| Keywords: | maize(Zea mays L.) half ridge removed-stubble reserved sowing yield output value |
