施肥是促进林木生长、提高产量和质量的重要措施之一。为了解肥料对麻疯树幼林结实的影响,试验研究了不同施肥水平对麻疯树生长及结实的影响。结果表明:麻疯树的株高、总新梢生长量、地茎粗、挂果数和千果重随着施肥量的增加而增加;果枝率、成果率和出仁率则是先增加后降低。当施肥量为0.4 kg/株时果枝率和出仁率最高,分别为81.54%和64.18%;当施肥量为0.2 kg/株时成果率最高,达到95.82%。
Fertilization is one of the important measures to promote forest growth and increase yield and quality. In order to understand the effect of fertilizers on the seedling growth of Jatropha curcas, the effects of different fertilization levels on the growth and fruiting of Jatropha curcas were studied. The results showed that the plant height, the total shoot growth, the stem diameter, the number of fruiting bodies and the weight of dry weight of Jatropha curcas increased with the increase of fertilization rate. The fruiting branches rate, fruit yield rate and kernel rate increased at first and then decreased . When the fertilizer application rate was 0.4 kg / plant, the fruit branch rate and kernel rate were the highest, which were 81.54% and 64.18%, respectively. The highest yield was 95.82% when the fertilizer was 0.2 kg / plant.
