我省高山林区多采用荫棚育苗、幼苗大部生长较细弱、缓慢,对病害和不良气候的抗力差。我们进行喷灌全光育苗。 一、喷灌全光育苗。 在海拔2600米处,年平均温5.3℃,年降雨量529毫米的南坪林区,采用细致整地、重施底肥,苗床高20厘米。种子用赛力散拌种,每斤用药1克,分床定量、宽幅条播,播种时以锯末混腐熟堆肥代替竹廉覆盖,覆盖厚度1厘米。播种后按每亩用2%硫酸亚铁液1.500—
High mountain forests in our province use shade shed nursery, most of the growth of seedlings more delicate, slow, poor resistance to disease and adverse weather. We carry out sprinkler irrigation seedlings. First, spray all seedlings nursery. In 2600 meters above sea level, the average annual temperature of 5.3 ℃, annual rainfall of 529 mm Nanping forest area, the use of meticulous preparation, re-applied base fertilizer, seedbed height 20 cm. Seed with Saracen bulk species, 1 g per catty medication, sub-bed quantitative, broad-band sowing, sawn mixed rotten composting to replace bamboo cover, covering a thickness of 1 cm. After sowing per acre with 2% ferrous sulfate solution 1.500-
