本省河网平原、河谷平原以及山谷洼地中,凡地下水位高而排水不良的稻田,土壤通气性也不良好。这些稻田,特别是在多肥、密植的条件下,水稻在幼穗形成后,常常发生稻根腐烂发黑现像,而且愈到后期愈为严重,有时竟可达到不见新根的程度,这对实现高额丰产极为不利。所以解决稻根发黑腐烂问题,在农业生产上具有重大的实践意义。这种稻根腐烂发黑原因,初步认为主要是由于土壤通气不足、氧气缺乏所造成的,因此,引起了我们对土壤氧化剂防治水 The provincial river network plains, valley plains and valley depressions, where high groundwater levels and poor drainage paddy, soil aeration is not good. In these paddy fields, especially under more fat and dense planting conditions, the phenomenon of rice root decay and blackening often occurs in young rice after it is formed, and it becomes more severe in later stages, sometimes reaching the level of no new roots, which Very detrimental to achieving high yields. Therefore, to solve the problem of rice root rotting black and has great practical significance in agricultural production. This rice root decay black reason, initially believed mainly due to insufficient soil aeration, lack of oxygen caused, therefore, caused us to soil oxidant water control
