摘要
本文对两种不同灌溉方式(滴灌和沟灌)下的秋冬萝卜(RaphanusSativusL.)生长情况进行了比较研究.结果表明:秋冬萝卜的生长、产量与灌溉方式有较密切关系.与沟灌方式相比,滴灌下萝卜的相对生长速率、净同化率、叶面积比率、比叶面积、叶重比、根冠比等指标以及产量都明显提高;采用滴灌方式,也有利于萝卜品质的提高.
The growth of Raphanus Sativus L. under two different irrigations were studied in this paper. The results showed that the growth and yield of R. Sativus were closely related to irrigation treatments. Compared with those in the furrow irrigation treatment, there were obvious increases in some aspects, such as the relative growth rate, net assimilation rate, ratio of leaf area to crop weight, ratio of leaf area to leaf weight, ratio of leaf weight to crop weight and ratio of root weight to crown weight of R. Sativus in the drip irrigation. Moreover, the qualities and yields of R. Sativus of the drip irrigation can be enhanced obviously.
