陝西省榆林地区为了作好固沙工作,在7月中旬用安二型飛机試播沙蒿十九万畝。据播后一星期的檢查,平均發芽率在60％以上,而且生長旺盛。 飛机播种固沙在我国还是第一次,通过这次試种,証明用飛机播种固沙能达到多快好省的目的。 飛机播种速度快、播得多。榆林地区林地近的离机場五公里,远的約二十公里,每日每架飛机平均播种三万市斤左右,播种面積二万四千畝,相当于人工播种的一千二百倍。飛机播种的种子分布非常均勻;同时种子在种倉里
Yulin, Shaanxi Province, in order to make sand-fixing work, in mid-July with Ann II aircraft pilot Artemisia nineteen acres. According to the broadcast after a week of inspection, the average germination rate of 60% or more, and vigorous growth. It is the first time for seeding and sand fixing of aircraft in our country. Through this trial planting, we can prove that the purpose of seeding and fixing seaborne by aircraft can achieve the goal of more speed and better quality. Aircraft seeding speed, broadcast more. The forest land in Yulin area is about five kilometers away from the airport and about 20 kilometers far away. Every day, an average of 30,000 catties of sown land for each aircraft is planted. The sown area is 24,000 hectares, equivalent to 1,200 times that of artificial sowing. Seed sowing seeds are distributed evenly; at the same time the seeds are in the silos
