毛白杨是我国特有的优良速生树种之一。但由于扦插难于生根,繁殖较慢。为提高苗木产量和质量,夏邑县王岳楼苗圃从1980年开始,采用了“埋棵连续育苗法”,效果很好,平均每年亩产3-4米高的优良苗木4,000株左右。现将育苗方法简介于下。一、圃地选择与整地作床圃地应选地势平坦,排灌方便,土壤肥沃,病虫害少的沙壤土或壤土。盐碱地和粘重地不宜选用。于秋末冬初进行整地,耕地深30-40厘米,结合耕地每亩施优质农家肥8,000斤左右,碳酸氢铵50-80斤,并进行土壤处理。翌年3月上、中旬浅耕细耙,以备开沟作垄。3月中下
Populus tomentosa is one of the unique fast-growing tree species in our country. However, because cutting is difficult to take root, reproduction is slow. In order to improve seedling yield and quality, Xiayue Wang Yue Lou nursery started from 1980 and adopted the “Buried continuous nursery method”. The effect is very good, with an average of about 4,000 excellent seedlings of 3-4 meters per mu each year. Breeding methods now outlined below. First, the choice of land preparation and land preparation For the bed should be selected flat topography, irrigation and drainage convenience, fertile soil, pests and diseases less soil loam or loam. Saline and sticky ground should not be used. Land preparation will be carried out in late autumn and early winter. The cultivated land is 30-40 cm deep. Combine the cultivated land with 8,000 kg of high-quality farmhouse fertilizer and 50-80 kg of ammonium bicarbonate and soil treatment. The following year in March, mid-shallow tillage harrow to prepare for ditch for the ridge. Middle of March
