近两年我县各基点试验结果和许多研究资料证明,磷肥集中使用,如沾秧根、栽盆盆秧、点蔸等是水稻施磷的有效方法。但是存在着花工较多,延误插秧季节的缺点,不易普遍推广。又因在水稻插秧时才施用,如果秧田缺乏可给态磷素的供给,就不可能满足秧苗早期对磷肥的需要,便会在一定程度上影响水稻增产。为了寻找省工、省肥、简便而有效的磷肥施用方法,我们于1964年在马前区同心五
In the past two years, the results of many basic points in our county and many research data have proved that concentrated use of phosphate fertilizer, such as polluting roots, potted pots and pods, is an effective method for phosphorus application in rice. However, there are more flower workers, the shortcomings of planting season delayed, not easy to promote. Due to the rice seedling transplanting, it is impossible to meet the needs of early seedlings for phosphate fertilizer if the seedling lacked the available supply of state phosphorus, which would to a certain extent affect the yield increase of rice. In order to find the provincial workers, provincial fertilizer, simple and effective method of application of phosphate fertilizer, we were concentric in the Mae Ma district in 1964
