摘  要:
红砂播种出苗比较困难。采用对比法,探索民勤荒漠区红砂种子露田种子育苗过程中播种量、播种深度、播种时间、播种方式、覆盖材料和灌水量等措施对种子出苗和幼苗生长的影响。结果表明:红砂露地膜上穴播以6月上旬、90~120粒/穴,播深0.5 cm、覆盖细河沙加覆白色保湿布出苗效果最佳,加覆白色保湿布后出苗期间漫灌3次,出苗穴率可达55%左右;苗木生长期以漫灌3~5次为佳,当年苗高可达15 cm。

摘  要:
Seedling emergence of Reaumuria songorica is difficult.The effects of sowing quantity,sowing depth,sowing time,sowing method,covering material and irrigation amount on seed emergence and seedling growth of Reaumuria songorica in Minqin desert area were studied,using a comparative analytical method.The results showed that the best hole sowing method was 90-120 grains/holein early June,0.5 cm deep sowing,mulching fine river sand and mulching with white moisture-retaining cloth.Besides,flooding irrigation 3 times during the emergence period after mulching white moisture-retaining cloth,the rate of seedling emergence was about 55%,and the best time for seedling growth was during 3~5 times of flood irrigation,and the seedling height could reach 15 cm in the same year.
