排水不良的稻田土壤,因氧化能力及通气性不佳,所以肥分不易被稻株吸收,而且这种土壤也往往缺乏有效矽,造成水稻根部发育受阻,耐氮能力弱,植株生长不健强,而且容易发生稻瘟病、白叶枯病,以及叶基部老化的现象,至使水稻发生倒伏问题。为 Poorly drained paddy soil due to poor oxidation and aeration, so fertilizer is not easily absorbed by rice plants, and this soil often lack of effective silicon, resulting in the development of rice root blocked, weak nitrogen tolerance, poor plant growth , And prone to rice blast, bacterial leaf blight, and leaf base aging phenomenon, so that rice lodging problems. for
