摘　　要：据有关统计资料表明,干旱、半干旱地区占我国国土面积的45%,由此我们可以看到干旱、半干旱地区农业的发展是制约我国农业可持续发展的重要因素之一。在东北的半干旱地区,由于春季干旱造成土壤墒情的不足,严重影响着大田作物的出苗和前期生长发育。多年来该地区的群众创造了不少抗旱播种好经验,坐水种就是当地一种较好的抗旱播种方法,该方法不仅省水,并且水肥集中、保苗率高、增产效益好。以甘南县田间试验为基础,在有限坐水条件下,通过采用不同的坐水种植方案对东北半干旱地区玉米前期的生长发育进行了研究,并予以了定量的描述。表6,参4。According to statistics,dry and semi-dry land occupy 45% area in our country.It can be seen from this that the development in the district is one of the important reasons that affect the agricultural development in China.In the northeast of China,because of the drought in spring lead to the lack of soil water,which influent sprout and seedling of crops gravely.The indigenes had many good ideas to sow in drought condition and it is a better way to storage water under the seed.The mean not only had saved the water but also had made water and fertilizer concentrate.This article is on the basis of field experiment,study on the effect on the previous maize growth by sowing with water in northeast district.
