本试验对苏南地区“麦—玉米—稻”三茬品种的搭配;肥料的运筹;大麦的播幅和玉米、后作稻的种植密度,以及玉米的种植方式等进行研究。经1991～1993年三年的试验结果表明:“麦—玉米—稻”的增产途径,选用良种是前提,合理密植是基础,科学用肥是关键,从而总结了一套适合苏南地区特点的“麦—玉米—稻”高产栽培技术。1试验方法 为充分利用苏南地区的温光资源,优化种植结构,提高种粮的经济效益,1990年立题在市农技推广中心开展以“麦—玉米—稻”新型多熟制的试验研究,供试地点在市农技中心试验区。在三年时间内
In this experiment, we studied the combination of the three wheat varieties “Maize-Maize-Rice” in southern Jiangsu Province; the operation of fertilizer; the spreading of barley and the planting density of maize and later-made rice; and the planting methods of maize. The results of three years from 1991 to 1993 showed that: “Maize - Maize - Rice” is the prerequisite for increasing yield and selecting good varieties. Reasonable close planting is the foundation and scientific fertilization is the key. Thus, a set of suits for the characteristics of southern Jiangsu “Wheat - corn - rice” high yield cultivation techniques. 1 Test Methods In order to make full use of the temperature and light resources in southern Jiangsu, optimize the planting structure, and increase the economic benefits of grain planting, the “Triticum aestivum-corn-rice” new multi-cooked trial Research, test sites in the city of agricultural technology center test area. In three years time
