航空播种水稻在国外已有50余年历史,许多国家广为应用。1967年我国国营八五七农场与民航局合作,首次使用飞机在秋翻春耙田进行水直播试验,1968、1975、1976和1977年,国营八五○、云山和江川农场,又进行了同项多点试验,均获成功。由于使用民航原有喷撒农药设备的飞机进行,载量少,工效低,飞机每架次只能载干稻种650公斤,在亩受种量35斤的情况下,仅播37亩。飞行作业成本较高,每亩达2元,且喷撒不够均匀。为降低生产成本,提高播种
Airborne sowing rice has been in foreign countries for more than 50 years and has been widely applied in many countries. In 1967, China’s state-owned 857 farm cooperated with CAAC and conducted the first water-borne experiment of using watercrafts in autumn and spring harrow fields. In 1968, 1975, 1976 and 1977, the state-owned 805, Yunshan and Jiangchuan farms also conducted The same multi-point test, were successful. Due to the use of the original CAAC aircraft sprayed by CAAC, the load is small and the work efficiency is low. Only 650 kg of dry rice can be carried in each flight of the aircraft. In the case of 35 kg of mu, only 37 mu is sown. High cost of flight operations, up to 2 yuan per mu, and spray enough uniform. To reduce production costs and improve sowing
