不同播期对棉花出苗早晚、苗病和生长发育均有不同的影响。在一定播期范围内,播种早晚主要影响出苗和苗期的长短,对现蕾以后的生育进程作用较小。而播种过早,苗病重,生育慢,不利于全苗壮苗,易形成老苗、出现后期早衰;过晚播种,就降低了地膜覆盖的效用。温度是决定播期的主要条件,统计分析表明,膜内外5厘米地温存在着高度的相关性,据此推算,当露地5厘米地温稳定通过11℃时,膜下5厘米地温可达13—14℃,已能满足棉种发芽出苗的要求,可视为棉花地膜覆盖播种适期的温度指标。综合考虑以上因素,结合我省气侯特点,提出棉花地膜覆盖适宜播种期范围为4月5日—15日,一般比露地直播提早5—10天播种为宜。

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。

This experiment was conducted in semiarid Wuqi County where annual rainfall is about 400 mm.The following main research contents are included in the experiment:the aerosowing result of Caragana microphylla,its biological and ecological characteristics,the sowing time and seed quantity and aerosowing technology.The results showed that Caragana microphylla is a suitable species to aerial sowing in the semiarid region.The suitable sowing time was deter- mined in the eve or at the begining of rainy season with seed quantity of O.8-1.2 kg/mu.This experiment provided scientific bases for expediting afforestation of the Loess Plateau.

本试验在年降水量400毫米的半干旱地区吴旗县进行,主要内容有:柠条(Caragana micro-Phyllalam)的飞播效果、生物生态学特性、播种期、播种量和飞播技术等。试验结果表明:柠条是半干旱区适宜飞播的树种,适宜的飞播期在雨季前或雨季开始时,播种量约每亩0.8-1.2公斤。本试验为快速绿化黄土高原,建立人工植被提供了科学依据。
