施肥是促进林木生长、提高产量和质量的重要措施之一,为了解肥料对膏桐幼林结实的影响,采用随机区组试验设计,对膏桐幼林进行施肥配方试验,结果表明:仅施用氮肥对膏桐增产作用不大,但仅施磷肥或钾肥却对膏桐增产起明显的促进作用,在氮、钾一定时,施磷肥量超过一定水平,对膏桐产果量影响不大,施肥处理对出仁率和出油率影响不明显。
Fertilization is one of the important measures to promote tree growth, yield and quality. In order to understand the effect of fertilizers on the seedling growth of Jatropha curcas, randomized block design was used to test the fertilization formula of young Jatropha curcas young plants. The results showed that only applying nitrogen fertilizer However, the application of P or K fertilizers only promoted the increase of Jatropha curcas, but when the N and K were fixed, the amount of applied P over a certain level had little effect on the yield of Jatropha curcas, and the fertilization treatment The kernel rate and oil yield is not obvious.
