2BXS-12A型旋耕播种机在粤北旱作玉米地适应性试验研究
Research on Adaptability of 2BXS-12A Rotary-tillage Fertilizing and Sowing Machine in Dry Cultivation Maize Field of Guangdong
摘要
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.关键词
