摘 要:通过对胡桃楸进行早播扣棚育苗试验研究,结果表明:胡桃楸早播扣棚育苗技术克服常规育苗出苗不整齐、倒春寒引起枯梢现象;该项技术比常规育苗能延长生长期45d,地径生长量提高23.28%,苗高生长量提高64.44%,侧根数提高40%,侧根长提高8.3%。Seedling-raising experiments of early-sowed J uglans mandshurica by covering plastic greenhouses were conducted.Result shows that this technology can overcome irregular emergence,late spring causes dieback phe-nomenon;the growing season,ground diameter ,lateral number and lateral length is increased by 45 d,23.28%, 64.44%,40% and 8.3% ,respectively than that by adopting conventional seedling-raising by adopting this technolo-gy.
