| 摘 要： | 在青海云杉育苗过程中,通过设立田间对比试验,研究了不同播种期、播种量、苗床高度、遮阳网对产苗量和生长量的影响。结果表明:在不同播期处理中播期4月15日的产苗量和苗高最高,分别为235.53株/m2和7.26cm;在不同播种量处理中播种量12g/m2的产苗量最高,为605.64株/m2,播种量9g/m2的苗高最高,为7.26cm;在不同苗床高度处理中阳畦苗床的产苗量和苗高最高,分别为255.43株/m2和7.34cm;在不同遮阳网处理中网孔(长×宽)0.5cm×0.5cm遮阳网的产苗量和苗高最高,分别为389.42株/m2和7.84cm。综合考虑产苗量、生长量和越冬性后,建议在天祝青海云杉育苗过程中,4月15日播种、9kg/m2的播种量、阳畦苗床播种,网孔(长×宽)0.5cm×0.5cm的遮阳网覆盖有利于提高产苗量和生长量。

| Abstract: | Field contrast test is conducted in grow seedlings of Picea crassifolia kom,and effects of different seedtime,seedling quantity,seedbed height,sunshade nets on amount and growth were studied. The result showed that the highest amount and height of 15 thApril are 235. 53 plant / m^2 and 7. 26 cm in different seedtime treatments; the highest amount of 12 g / m^2 is 605. 64 plant / m^2,the highest height of 9g /m^2 is 7. 26 cm in different seedling quantity treatments; the highest amount and height of 25 cm seedbed are 255. 43 plant / m^2and7. 34 cm in different seedbed treatments; the highest amount and height of（ length × width） 0. 5cm × 0. 5cm sunshade net are 389. 42 plant / m^2 and 7. 84 cm in different sunshade net treatments,the measures of 15 thApril,9kg / m^2,25 cm,0. 5cm × 0. 5cm can improved amount and growth of Picea crassifolia kom in Tianzhu after think amount,growth,and mortality rate. |
