耐肥性是水稻品种的重要属性之一,尤其在科学技术发达,工农业生产迅速发展的情况下更应引起重视。纵观水稻品种的发展史,不难发现,随着化肥工业的发展和农业经营集约化程度的提高,水稻品种也是逐步朝着耐肥高产这个方向而演变的。然而,对这样一个重要特性,国内外的研究报导却为数不多。马场(1956)认为,水稻品种对稻瘟病的抗性及抗倒伏性,在广义上应包含在品种耐肥性的范围之内,但又认为这两种抗性是另一问题,不包含在最基本的耐肥性——真正的耐肥性(狭义的耐肥性)之内。他又把狭义的耐肥性区别为形态的耐肥性(株型)和生理的耐肥性,认为多穗型品种的耐肥性一般大于大穗型品种;植株对已吸收氮
Fertility resistance is one of the important attributes of rice varieties, especially in the developed science and technology, industrial and agricultural production should be paid more attention in the case of rapid development. Throughout the history of the development of rice varieties, it is not difficult to find that with the development of the fertilizer industry and the intensification of agricultural management, rice varieties are gradually evolving in the direction of high yield and high yield. However, there are only a few research reports at home and abroad on such an important feature. Racecourse (1956) that the rice varieties of rice blast resistance and lodging resistance, in a broad sense, should be included in the range of varieties of tolerance, but that these two resistance is another problem, not included in The most basic resistance to fertilizer - the real resistance to fertility (narrow sense of tolerance) within. He again narrowed the narrow tolerance of the morphological resistance to fertilizer (plant type) and physiological resistance to fertility, multi-spike varieties that the resistance is generally greater than large-spike varieties; plants have been absorbed nitrogen
