摘要
进行盆栽试验,研究不同质地土壤底墒对玉米出苗及苗期生长的影响,结果表明:土壤底墒对玉米出苗率、株高和苗期总干物重影响显著。玉米出苗率、株高和苗期总干物重随着土壤底墒的增加而增加,达到最高值后,随着土壤底墒的增加而减小。壤土出苗率、株高和苗期总干物重最高的适宜底墒范围为19%-22%,粘土为26%-29%,沙土为13%-15%。
A pot experiment was carried to study the effects of the rate of seedlings emergence and the growth of the maize seeding under different type of soil moisture in sowing.The results showed that the rate of seedlings emergence、plant height and total dry substance weight of maize would increase with the enhancing of soil moisture in sowing.but the rate of seedlings emergence、plant height and total dry substance weight of maize would reduce with the increasing of soil moisture in sowing when soil moisture content surpasses Certain scope.the highest rate of seedlings emergence、plant height and total dry substance weight of maize of suitable soil moisture in sowing was 19%-22% in loam soil,was 26%-29% in clay soil,but was 13%-15% in sand soil.
