摘要
研究了缓释复合肥对旱薄地花生产量及生长性状的影响。结果表明,与单施同等养分含量的复合肥相比,一次性单施缓释肥能有效促进花生后期生殖生长,提高花生结果数,增加百果重,但对花生营养生长的促进作用较小,增产效果不如普通三元复合肥。缓释肥与纯鸡粪(有机肥)配施效果好于复合肥与有机肥配施、单施复合肥和纯鸡粪,增产效果显著且种植效益好。因此缓释肥在旱薄地花生上应用,应坚持有机与无机相结合、培肥地力,确保花生前期营养生长,在建立足够"源"的基础上,充分发挥缓释肥对"库"的促进作用,提高花生单产。
Effects of controlled release fertilizer on yield and growth characteristics of Huayu No. 23, a peanut vanety, was studied in this paper. The results showed that the controlled release fertilizer as base fertilizer could improve reproductive development of peanut at the later growth and development period, increase the pod number per plant and 100-pod weight. However, it had little effect on accelerating vegetative growth and the increase of production was not as good as compound fertilizer. The effect of mixed application of the controlled release fertilizer and manure was better than mixed application of the compound fertilizer and manure, also better than only application of manure and compound fertilizer. Therefore, the application of the controlled release fertilizer on peanut at barren dryland should combine with the application of manure to promote the nutritional level in soils to insure the vegetative growth of peanuts.
