| 摘 要： | 2BXS-12A型旋耕施肥播种机在北方适应性良好,本文通过该机具在广东粤北旱作玉米地的性能试验来检测其适应性。田间试验表明,当试验用玉米种子为南校968,实际排种量为34.5 kg/hm~2,在正常工作条件下,玉米排种量为30~40 kg/hm~2,实际排种量在这个范围内;播种均匀性变异系数为57.576%45%,空段率为6.67%5%,旋耕播种机的播种均匀性未能达到要求,机具有待进一步的改进。

| Abstract: | Adaptability of 2BXS-12A rotary-tillage fertilizing and sowing machine in the northern is good, in this paper, we can test its adaptability through the performance experiment in dry cultivation maize field of Guangdong. The field test results showed that as followed, when the experimental seeds were Nanxiao968, the actual sowing quantity was 2.3kg per mu, under the normal conditions, it's 30~40 kg/hm2, the actual sowing quantity was in this range; the variation coefficient of seeding uniformity was 57.576%>45%, empty section rate was 6.67%>5%, the sowing uniformity of the machine can not meet the requirements, and need further improvement. |
