枫杨是落叶乔木,生长迅速,10—15年可成大材,是我县“四旁”绿化理想的乡土树种之一,很受群众欢迎.我县城东公社四塘七队于1983年4月上旬播种0.5亩枫杨,由于种子处理不当,播后不见出苗.4月24日,我们与该队签订了技术承包合同,为了提高迟播枫杨种子的发芽率、发芽势和促进苗木快速生长,保证当年培育大苗壮苗,我们根据枫杨的生物学特性,严格技术要求,加强管理,经过几个月的努力,已收到良好的效果.平均苗高1.7米以上,平均地径1.9厘米,最高达2.0米以上,长势喜人,每亩产量11,000株左右.在育苗过程中,着重抓了以下三方面的技术措施.种子催芽处理采取热水浸种催芽法.首先将种子进行筛选,去杂去劣,然后将2倍于种子的热水(约80℃左右)倒入备好的大缸里,边倒种子边用木棒搅拌,待水冷至不烫手为止,捞出浮在水面上的瘪粒种子,其余经浸泡二天
Maple is a deciduous tree, growing rapidly, 10-15 years can be a large timber, is my county “four sides” green one of the ideal native tree species, very popular with the masses. I County East commune four pool of seven teams in April 1983 On the 24th of April, we signed a contract of technology contract with the team. In order to improve the germination rate, germination potential and the rapid growth of seedlings in late spring poplar seed, , To ensure vigorous seedlings nurturing seedlings that year, according to the biological characteristics of Maple, strict technical requirements, and strengthen management, after several months of efforts, has received good results. The average height of 1.7 meters above sea level, the average diameter of 1.9 cm , Up to 2.0 meters above the growth of gratifying, yield about 11,000 per mu. In the process of nursery, focusing on the following three aspects of technical measures .Seed germination to take hot water soaking germination method .Seeds first screening, to miscellaneous To bad, and then 2 times the seeds of hot water (about 80 ℃) into the prepared tank, while the side of the seeds with a stick stirring, until the water until it is not hot, remove and float on the water Deflated seeds, the rest by soaking two days
