为了探索适宜的华北低平原区油葵种植模式,通过田间试验,比较研究了干播湿出膜下滴灌和传统的冬春灌覆膜播种方式在华北低平原区对油葵生长发育的影响.结果表明:干播湿出膜下滴灌较传统的冬春灌覆膜播种可以有效降低油葵株高,增大茎粗,提高油葵的抗倒伏能力;同时可以有效地提高土壤表层温度,并为油葵苗期生长发育和地下部生长提供有利的土壤环境,能促进油葵根系生长,增加地下部生物量,提高产量.“,”In order to explore the suitable mode of planting canopy in low plains of North China,experiments were done for comparing differences between the influence of a new mode sowing with covering film before drip irrigation and the traditional mode sowing with covering film after irrigation during winter and spring on the development of canopy in low plains of North China.The results showed that,the method sowing with covering film before drip irrigation could effectively save irrigation water and improve the ability of resistance to lodging by reducing the plant height and increasing the stem diameter.The new model could effectively improve the surface layer soil temperature for canopy,offer seedling stage growth and the growth of underground part benefitial soil environment.It would promote the canopy root growth,increase the underground biomass and increase production.
