This paper describes the suitability of Astragalus adsurgens by aerial so- wing and technology of improving aerial sowing effects in the area where an nual precipitation is about 250 mm. It indicates that the major factors affecting effects of aerial sowing Astragalus adsurgens are drought, low temperature and calamitles caused by wind and sand.

This paper describes the suitability of Astragalus adsurgens by aerial so- wing and technology of improving aerial sowing effects in the area where an nual precipitation is about 250 mm. It indicates that the major factors affecting effects of aerial sowing Astragalus adsurgens are drought, low temperature and calamitles caused by wind and sand. To dotermine suitable sowing time (late June or early and middle July before raining season begins), sown areas (a large area where the cultivated land is turned into waste or turned into forest and grass land) and plowing surface and treating seeds are the efficient technical measures to increase aerial sowing effects. The experimental results showed that the dense high grassland could be formed after Astragalus adsurgens grown for three years, survival seedling rate is 85.5-100%, fresh grass yield is 493.5 kg/mu (the highest is 2, 034.3 kg/mu), which is 6.8 times as much as that of closed waste land. Aerial sowing Astragalus adusurgens has shown markable economic and ecological benefits.

本文比较深入地探讨了在年降雨量250毫米左右条件下,沙打旺适于飞播的能力和提高飞播效果的技术。干旱、低温和风沙灾害是影响沙打旺飞播效果的主要因子;选择适宜的播期(雨季来临前夕的6月下旬至7月上、中旬)、播区(具有大面积退耕地和撂荒地)并采取地面处理和种子处理,是提高飞播效果有效的技术措施。试验结果表明,沙打旺播后第三年,即可形成郁闭的高草地,成苗面积率达85.5-100%,平均亩产鲜草493.5公斤(最高可达2,034.3公斤),为同期封禁荒地产草量的6.8倍。经济改益和生态效益显著。

Astragalus adsurgens grew luxuriantly from 3 to 5 years, while the growth of natural herbs were restrained. Astragalus adsurgens can fully use water in soil with a developed root system.

This experimed was carried out on the sown area of Astragalus adsurgens in sendarid Wuqi County during the period from 1980 to 1985. The survey showed that the life of Astragalus adsurgens from thrivingness to decline is a rapid succession series. Its importance value changed obviously. Astragalus adsurgens grew luxuriantly from 3 to 5 years, while the growth of natural herbs were restrained. Astragalus adsurgens can fully use water in soil with a developed root system. The water in declined Astragalus adsurgens grassla- nd was faster than that in natural grassland and farmland. The soil moisuret in upper layer of soil in declined Astragalus adsurgens grassland was higher than in natural grassland and farmland, advancing the growth of other plants. Astragalus adsurgens can improve the soil structure and change its physical and chemical properties. Thus, the goal of improving and bettering soil, as well as promoting the plant yield can be attained.

本试验于1980-1985年在半干旱的陕西省吴旗县沙打旺飞播区进行。试验结果表明:沙打旺从兴盛到衰败,出现一快速演替系列,其重要值有明显的变化。第3-5年沙打旺生长繁茂,草地内天然草受抑制。沙打旺能利用发达的根系,充分利用土壤水分。衰败沙打旺草地水分渗透速率比天然草地和农地快,上层土壤含水量恢复较好,这样,其它植物在衰败地上长得更好。沙打旺可改良土壤结构、改变土壤理化性质,达到改土培肥,促进植物增产的目的。

The process of the formation of Pinus tabulaeformis stand by aerial sowing can be divided into three stages:stage of emergene (the sowing year), survival stage of seeding (2-4 year after sowing) and stage of the formation bf stand(5-9 year after sowing).The seedlings just coming up out of the ground are very fragile in the stage of emergence,so they are subject to damage.The seedlings in the survival stage of seedling grow slowly,and tran- splanting of them at this time is most suitable.The growth of seedlings...

The process of the formation of Pinus tabulaeformis stand by aerial sowing can be divided into three stages:stage of emergene (the sowing year), survival stage of seeding (2-4 year after sowing) and stage of the formation bf stand(5-9 year after sowing).The seedlings just coming up out of the ground are very fragile in the stage of emergence,so they are subject to damage.The seedlings in the survival stage of seedling grow slowly,and tran- splanting of them at this time is most suitable.The growth of seedlings speeds up in the stage of the formation of stand,They gradually form stand on the area with more seedlings.But the canopy must be thin for the seedlings of P. tabulaeformis distributed under the stand of Populus davidiana for the sake of speeding the process of the formation of stand.The practice showed that the forest area may account for about 30%of the total sown area,so long as the Suitable sown area and sowing time are chosen.

飞播油松成林过程可分为三个阶段,即出苗阶段、成苗阶段和成林阶段。出苗阶段(飞播当年),幼苗很不稳定,易遭损害,成苗阶段(2-4年),幼苗生长缓慢,这时进行移苗最为适宜;成林阶段(5-9年),幼苗生长加快,分布较多地段开始郁闭成林,但对山杨林下的幼苗,必须疏开上层林冠,以加快油松成林过程。实践表明,只要播区、播期选择适宜,该区飞播油松成林面积可望占30%左右。
