我市杂交稻制种由于多年来一直以投入化肥、磷肥为主,有机肥用量很少,近年来连续出现部分制种田母本栽插后难以活棵,僵苗等现象,严重影响了制种的产量和质量,从1991年开始,我们在制种田中推广使用了南京农业大学配制的“杂交稻制种专用肥”取得了明显的效果。 1 材料与方法 1.1 试验田的选择,试验田选在离村庄较远的塘
Due to many years of investment in rice hybrid rice in our city has been to fertilizer, phosphate-based, organic fertilizer use is very small, in recent years continued to part of the system after planting mother hard to live, stiff seedlings and other serious consequences for seed production Since 1991, we have achieved remarkable results by promoting the use of “special fertilizer for hybrid rice seed production” formulated by Nanjing Agricultural University in farming systems. 1 Materials and methods 1.1 The choice of experimental field, experimental field selected in the pond far from the village
