在粗砂潮土,对花生施用磷肥的增产效应、经济效益及其最佳施用量进行了试验研究。结果表明:在亩施磷肥2～12kg的范围内,对提高花生开花、荚果形成、饱果数、百仁果重与荚果出仁率等均有显著的效果,从而提高了花生的产量和经济效益。在本试验条件下,以亩施P_2O_58.19kg为最佳施磷量,花生亩产可达354.0kg,亩增收入51.53元,增产21.57％,增产效果好,经济效益高。 In the coarse sandy soil, peanut application of phosphate fertilizer stimulation effect, economic benefits and the best application rate were studied. The results showed that in the range of 2 ~ 12kg, the yield of peanut was increased with the increase of peanut flowering, the formation of pod, the full number of fruit, the weight of pome fruit and the kernel yield of pod. benefit. Under the conditions of this experiment, P2O5 -58.19kg was the best phosphorus application rate. The per-mu yield of peanut reached 354.0kg. The yield increase of mu was 51.53 yuan and the yield was 21.57%. The yield was good and the economic benefit was high.
