    摘要:

    苏州地区是我国著名的水稻高产地区之一,向以稻麦两熟为主.近些年来,稻-稻-麦三熟制的面积有了很大的发展,不少社队的复种指数达到了240%左右.探讨在这种高强度栽培制度下,土壤的养分供应状况及肥料效果问题,是有一定意义的.本文是我们在1974-1977年间对此问题进行研究中所获资料的总结.

    Abstract:

    1.Because the growing period of rice under "rice-rice-wheat" rotation,as compared with that under "rice-wheat" rotation,is greatly shortened,the amount of nitrogen mineralized in soil absorbed by rice plant is diminished to such a considerable extent that the need on fertilizer nitrogen has to be increased significantly.At the sane time,the dower rate of mineralization of soil nitrogen under low temperature in the early stage of early rice can not meet the need of higher nitrogen absorption rate of early rice at that time,and it is indispensible to increase nitrogen fertilizer applied in the early stage of early rice.
