过磷酸鈣沾秧根在低产地区、高产地区都有一定增产效果,去年我們在龙海县黎明大队实驗結果,每亩可增产50~100斤(今年气溫較低)。但高产地区推广磷肥沾秧根,群众不容易接受,而且沾秧根工作掌握不好,影响效果,可能达不到增产目的。为此,我們根据磷素在水稻体内的代謝特点,設計出几种代替沾秧根的施肥方法。經过对比 In the low-yielding areas and high-yielding areas, the superphosphate-stained roots have a certain yield-increasing effect. Last year, we had an experimental result of the Liming Brigade in Longhai County, which could increase the output by 50 to 100 kilograms per acre (lower temperatures this year). However, the popularization of phosphate fertilizer in high-yielding areas of roots, the masses is not easy to accept, and the operation of the root cause is not good, affect the results may not reach the purpose of yield. Therefore, according to the metabolic characteristics of phosphorus in rice, we designed several methods to replace the seedlings. After comparison
