前言 花生是豆科油料作物,很喜磷肥。我省花生产区土壤的供磷能力较低,施用磷素化肥能显著提高花生的产量和品质。磷肥又能促进花生的生物固氮活动,因而在提高花生产量的同时,对后茬粮食作物的增产起着连应效果。因此,花生产区增施磷肥,是一项增加花生产量和不断培肥地力,取得粮油双丰收的重要措施。 本文综合1955—1972年十余年来的研究资料:对花生的磷素营养特点;施用磷肥增产效果和增产原因;影响磷肥效果的主要因素和经济有效施用技术等方面加以论述,供作参考。
Preface Peanut is legume oil crops, hi phosphate. The capacity of phosphorus supply in the soil of flower production area in our province is lower. The application of phosphorus fertilizer can significantly improve the yield and quality of peanut. Phosphate fertilizer can promote the biological nitrogen fixation of peanut, thus increasing the yield of peanut at the same time, the latter crop grain yield increase play a continous effect. Therefore, the application of phosphate fertilizer in flower growing areas is an important measure to increase the yield of peanuts and continuously fertilize the land, thus achieving a double harvest of grain and oil. This article synthesizes the research data from 1955 to 1972 more than ten years: the characteristics of phosphorus nutrition of peanut; the effect of increasing and increasing yield of applying phosphate fertilizer; the main factors affecting the effect of phosphate fertilizer and the economical and effective application techniques are discussed for reference.
