磷是作物种子里含量较多的营养元素,虽然在数量上还次于氮、钾,但在作物营养上却起着重要作用,它是形成核蛋白不可缺少的元素。据国外有关文献和资料报导:“高度的土壤肥力是抵御低温的基础,它对气象变动能起一定缓冲作用”。“不施堆肥的冷害年份严重减产,施堆肥的减产较轻,而施堆肥与施磷肥结合,减产最轻”,“高氮肥(3倍)处理,水稻穗分化始期比对照晚7天,相反,高磷肥(4倍)处理都提早8天”。国内有关研究报
Phosphorus is a nutrient that is abundant in crop seeds. Although phosphorus is inferior to nitrogen and potassium in quantity, it plays an important role in crop nutrition. It is an indispensable element in the formation of nuclear proteins. According to foreign literature and information reported: “a high degree of soil fertility is to resist the foundation of low temperature, it can play a buffer role in weather changes.” “Year without chilling injury of compost severely reduced production, less compost applied with compost, and combined application of compost and phosphate fertilizer, the lightest production”, “high nitrogen fertilizer (3 times) treatment, the beginning of rice panicle differentiation 7 days later than the control, on the contrary , High phosphate fertilizer (4 times) treatment are eight days earlier. ” Domestic research report
