| 摘 要： | 稻茬冬小麦不同播种方式和播种量试验于2008—2009年度在江苏省农业科技综合展示基地(宿迁点)进行,试验共设计4种播种方式和3个播种量水平,研究分析不同播种方式和播种量及气象条件对稻茬冬小麦生长发育、抗逆性和产量的影响。结果表明:播种方式和播种量对冬小麦的生长发育及产量有显著影响,在生产实际中应结合具体情况采取适当的播种方式,播种量水平以每亩20万株左右基本苗较理想。在粳稻收获较晚,冬小麦无法适期播种时,可以采取稻田套播方式,播种量要适当增加;籼稻腾茬早的,可以选择收获后7 d左右人工撒播或条播;在茬口和气候等条件适宜的情况下,尽可能采取水稻收获后2 d左右进行冬小麦播种。条播能更充分的利用光温水等气候资源。

| Abstract: | Study on the influence of sowing style and seeding rate on winter wheat growth in rice stubble land in 2008-2009 was carried out in Suqian point of Jiangsu agricultural science and technology integrated exhibition base. The growing development, resistance and production were discussed for four sowing styles and three seeding rate levels. The results showed that sowing styles and seeding rate have significant influence on the growth and production of the winter wheat. The best sowing rate should be about 200 thousand per mu. If the winter wheat can not be seeded on time, japonica rice can be increased by interplant wheat in paddy. 7 d after the nonglutinous rice havest is considered to be suitable for artificial sow or drill. If the crops for rotation and the weather are favorable, the winter wheat sow should be shifted to a earlier time, numely 2 d after the rice harvest, and it is important to note that drill sowing can take more advantages of temperature and light to get higher yield. |
