为了了解枸杞落花落果的原因及防止措施,更好地发展枸杞生产,我们于1979—1983年在中宁县进行了试验调查。1983年在中宁县和灵武农场园艺一队推广叶面喷施氮、磷、钾肥,有效地防止了枸杞的落花落果,一般采用N∶P∶K为1∶1∶1可减少落花落果提高座果率1.94—25.02%,亩增收枸杞34.11—59.5斤,增加收益225.11—390.98元。该项研究获1983年农牧渔业部科技成果二等奖。
In order to understand the reason and preventive measures of the falling berries of Lycium chinense and to better develop the production of Chinese wolfberry, we conducted a pilot survey in Zhongning County from 1979 to 1983. In 1983, Zhongning County and Lingwu farm horticultural team to promote the foliar application of nitrogen, phosphorus and potassium fertilizer, effectively preventing the fall of Chinese wolfberry fruit drop, the general N: P: K 1: 1: 1 can reduce the drop Fruit rate of 1.94-25.02%, increase the yield of 34.11-59.5 kg of Chinese wolfberry, increase income 225.11-390.98 yuan. The research won the second prize of scientific and technological achievements of the Ministry of Agriculture, Animal and Animal Husbandry in 1983.
