- 摘要:
- 针对黑龙江省西部半干旱区早春持续干旱,为降低玉米旱灾减产风险,以金庆707为材料,通过在龙江县进行田间试验,研究黑龙江半干旱区不同耕作模式对玉米水分利用率及产量的影响,探究玉米苗期的水分利用规律。结果表明:播种前,10~20 cm和30~40 cm免耕淋水处理和常规种植的容重差异显著。播种期、苗期和拔节期,免耕淋水处理和常规种植的土壤含水量差异显著。免耕淋水处理比常规种植的水分利用率提高3.98%,并且免耕淋水处理的经济效益比常规种植增加2 076.68元?hm-2。
- Abstract:
- In order to reduce the risk of maize drought and yield reduction in the western semi-arid region of Heilongjiang Province.Jinqing 707 was used as material to study the effects of different tillage patterns on maize water utilization and yield in Longjiang County,so as to explore the law of water utilization in maize seedling stage.The results showed that the effect of no-tillage watering on soil moisture content of 0-30 cm was significant.The water use efficiency of no-tillage watering was 3.97% higher than that of conventional planting.Moreover,the economic benefit of no-tillage watering was 2 076.68 yuan per hectare higher than that of conventional planting.
