我系对新垦红壤稻田发生“黄泥瘟”的研究,已证明“黄泥瘟”与土壤的磷素营养有密切的关系,是一种磷素营养缺乏的生理病。本试验是从土壤含速效磷的水平来探讨新垦红壤稻田水稻发生“黄泥瘟”的影响。一、试验设计供试土壤采自我院农场(广州石牌)花岗岩发育的不同含磷量(速效磷)的红壤。即土 I was on the Kennedy red paddy rice paddy field occurred “yellow mud blast” study has proved that “Huang mud blast” and the soil phosphorus nutrition are closely related to a lack of phosphorus nutrition is a physiological disease. In this experiment, the effect of “yellow mud plague” on paddy rice in the newly reclaimed red soil was discussed from the level of available phosphorus in the soil. First, the experimental design for the test soil collected from our hospital (Guangzhou Shipai) granite development of different phosphorus content (available phosphorus) of red soil. That soil
