摘要
为探索响水县旱茬小麦适宜的播种量,对济麦22不同播种量对产量及其构成的影响进行试验。结果表明:旱茬小麦济麦22在适期内播种,不同播种量对小麦产量影响有差异但达不到显著或极显著水平,10 kg/667 m2播种量的小麦分蘖率强,分蘖成穗率高,实收产量均高于12.5、15和17.5 kg/667 m2播种量的产量。说明响水县旱茬小麦在适期内播种,播种量控制在10~12.5 kg/667 m2之间,并配套好相应的栽培措施,可以获得较好的产量水平。
To determine the suitable seeding rate of wheat grown after maize in Xiangshui County, Jiangsu Province, a field trial was conducted to assess the effects of four different seeding rates of the wheat variety Jimai 22 on its yield and yield components. Results showed that with the wheat sown within the suitable period of time, the four treatments with different seeding rates differed in wheat yield, but their differences in yield did not reach a significant level. Specifically, the treatment with the seeding rate of 10 kg/667 m^2 showed a high tillering rate and tiller earing rate; its actual yield per 667 m^2 was greater than those of treatments with seedling rates of12.5, 15, and 17.5 kg/667 m^2. These results suggest that wheat grown after maize may attain a relatively high yield under the following conditions： sowing it in the suitable period of time, controlling the seeding rate between 10-12.5 kg/667 m^2, and adoption of matching cultivation measures.
