后季稻越熟施肥法就是将后季稻生长所需的肥料在早稻未收割前先施下,促其变成土壤中的潜在养分,及早释放提供后季稻生长需要。几年来的实践证明:这种施肥方法,一是利于后季稻早发棵,为穗多、穗大打下基础;二是可以减少因过迟提供肥料,而促成后季稻后期长得偏嫩,降低抗逆力,引起穗颈稻瘟病的加剧发生。有利于夺取后季稻高产、稳产。一、越熟施肥法由来后季稻穗颈稻瘟病的暴发,是历年来造成后季稻产量不高不稳的重要原因之一。而导致后季稻穗颈稻瘟病暴发严重的原因除了气候因子外,又同使用肥料是否恰当密切相
The more mature fertilization method of post-season rice is to apply the fertilizer required for the growth of the latter-season rice before it is harvested, and promote it to be a potential nutrient in the soil and provide early post-season rice growth needs. Practice has proved over the past few years: This method of fertilization, one is conducive to the early rice after the late rice, for the spike, spike lay the foundation; the second is to reduce the late provision of fertilizers, and contributed to the latter part of late rice grows more tender , Reduce the anti-stress, causing panicle blast aggravate. It will help to seize the high yield and stable yield of the latter season rice. First, the more mature fertilization method The origin of post-rice rice neck blast outbreak, over the years is caused by the latter part of rice production is not high and unstable one of the important reasons. In addition to climatic factors, but also with the use of fertilizer is closely related to the phase of rice blast caused by late outbreak of rice blast
