根茎唯他对马铃薯生理特性和产量影响的研究

Preliminary Study of the Impact of Rhizome Weita on the Growth and Yield of Potato

根茎唯他是以微量元素为复配主体的植物生长调节剂,试验结果表明:在马铃薯的初花期喷施根茎唯他能有效地促进地上部经济性状的改变,抑制地上部分高度的生长,增加分枝数、茎粗,提高产量,一般可增产10%～20%,同时能使马铃薯提前3d上市。

Rhizome Weita is a growth regulator of plant with trace elements as the main component. The experiment results show that：in the early flowering of potato, the spray of Rhizome Weita can ef- fectively promote the change of economic characters,inhibit the aboveground height growth,increase the number of branches,stem diameter to enhance production,which is generally 10-20% ＇s increase in production. Meanwhile, the potatoes can be launched into market three days in advance.
