花生施用磷肥增产效应分析

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、英果形成、饱果数、百仁果重与英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Ｐ２Ｏ５８．１９Ｋｇ为最佳施磷量，花生亩产可达３５４．０ｋｇ，亩增收５１．５３元，增产２１．５７％，增产效果好，经济效益高。

Analysis on the Yield-Increasing Effect of Applying Phosphate Fertilizer on Peanut

Results from the experimenl of applying phosphate fertilizol to peanut on coarse sandy soil to study its yield - increasing effeet, economic beneiit and optimum application volume showed that application of P-fertilizer within the range of 2-12kg per mu had marked effect on improving Slower amounl . pod fortning, pod plumpness, weight of hundred pods,rate of shelled peanuts elc. Therefore, it raised the yield of peanut and its economic benefit . In the experiment - the oplimum) application level of P-fertilizer is 8. 19kg per mu (P2O3), which could get yield of 354. Okg/mu, being 21. 57% higher than CK,and increaseed the income by 51,53, yuan,so the increase ef-fect was well and the economic benefit was high.
