采用框栽方法,研究灌溉水平对春大豆株高与产量的影响。试验选用三个不同类型大豆品种为材料,设置了三个灌溉水平。研究结果表明,大豆生育期间,随着灌溉水量的增加,土壤含水量明显增加,大豆株高和产量均表现为随灌溉水平增加而增加,但三个供试品种间有明显差异。绥农14和嫩丰18的T120处理的株高明显高于T100和T80处理,T100和T80处理差异不显著,合农60处理间差异均不显著;灌溉主要通过影响大豆中高位节间长度而影响株高,对低位节的节间长无明显影响;绥农14和合农60不同灌溉水平间产量差异显著。
The box planting method was used to study the effects of irrigation levels on plant height and yield of spring soybean. The experiment used three different types of soybean varieties as materials, setting three levels of irrigation. The results showed that during the growing period of soybean, the soil moisture content increased obviously with the increase of irrigation water. The plant height and yield of soybean all increased with the increase of irrigation level, but there was a significant difference among the three tested varieties. The plant height of T120 of Suinong 14 and Nenfeng 18 was significantly higher than that of T100 and T80, but the difference of T100 and T80 was not significant, but there was no significant difference between the treatments of Huainan 60 and 60. Irrigation mainly affected the length of internode in soybean Affecting plant height, but had no obvious effect on internode length of low node. There was significant difference in yield between different irrigation levels of Suinong 14 and Henong 60.
