大量的田间试验结果表明,施用稀土可使冬瓜(Benincasahispida)、马铃薯(Solanumtuberosum)、甘蓝(Brassicaoleraceavarcapitata)明显增产。据统计,平均增产率为:冬瓜17.4%、马铃薯12.4%、甘蓝7.1%、花椰菜10.6%。增产主要原因是提高了单果(及块茎、叶球、花球)重。通过对冬瓜、马铃薯、甘蓝施用稀土及La、Ce、Pr、Nd单一稀土的生理效应实验,证明稀土可以提高根系伤流量和叶绿素含量.增强对养分的吸收利用,从而促进营养生长,增加干物质积累。说明其增产效应,具有一定的生理基础。并通过试验提出了稀土有效施用的技术与条件。
A large number of field experiments showed that the application of rare earth melon (Benincasahispida), potato (Solanumtuberosum), cabbage (Brassicaoleraceavarcapitata) significantly increased. According to statistics, the average increase rate is 17.4% for melon, 12.4% for potato, 7.1% for cabbage and 10.6% for broccoli. The main reason for the increase is to increase the fruit (and tubers, leaf ball, flower ball) weight. Physiological effects of rare earths and La, Ce, Pr and Nd single rare earths on wax gourd, potato and cabbage prove that rare earth can increase root trauma and chlorophyll content. Enhance the absorption and utilization of nutrients to promote vegetative growth and increase dry matter accumulation. Explain its stimulation effect, with a certain physiological basis. And through the experiment proposed the effective application of rare earth technology and conditions.
