从有关部门获悉,我国水稻旱育稀植抛秧技术被农业部列为1996年全国重点推广的十大农业实用技术之首。自1996年底,全国水稻抛秧面积已达1200万亩,主要是人工抛秧。抛秧使水稻种植方式从弯腰插秧改为站立作业,是水稻种植方式的一次革命,但仍存在用工多、劳动强度大、抛撒均匀差等问题。大面积推广抛秧迫切盼望实现机械化。中国农业大学机械工程学院和黑龙江农垦科学院经过几年的研究、选型和试验,试制了20台锥盘式抛秧机,在北京、辽宁、江苏、上海、广东、海南等稻区进行试验。该机每小时可抛秧14亩,具有布秧均匀秧苗、返青快、分蘖力强、穗粒多、植株茎秆粗壮、抗倒伏等优点。
Learned from the relevant departments, China’s rice nursery and sparse planting throwing technology was listed as the Ministry of Agriculture in 1996 focused on the promotion of the top ten practical agricultural technology. Since the end of 1996, the area of rice throwing has reached 12 million mu, mainly for artificial throwing. Throwing rice transforms the rice planting mode from stubble planting to standing homework, which is a revolution in the rice planting mode. However, there are still many problems such as heavy labor, heavy labor intensity and poor throwing. Large area to promote throwing seedlings urgently hope to achieve mechanization. After several years of research, selection and experiment, China Agricultural University School of Mechanical Engineering and Heilongjiang Academy of Reclamation Sciences piloted 20 cone-type rice transplanter for trial in Beijing, Liaoning, Jiangsu, Shanghai, Guangdong and Hainan. The machine can throw seedling 14 acres per hour, with a uniform seedling seedlings, back green fast, strong tillering, spike and more stout plant stalwart, anti-lodging and so on.
