摘要
柿在秋季采用稻草、麦秸和地膜覆盖实生播种育苗,出苗期和苗木质量都好于不覆盖裸地播种育苗。其中,地膜覆盖的出苗期比未覆盖(CK)提早20d,出苗率、苗木高度、苗木粗度和苗木根系长度分别比CK平均提高33.0%、33.1cm、0.29cm和9.1cm。该项新技术大幅度提高了出苗率,降低了育苗成本,建议在生产中推广。
Based on some previous experiments, this paper made a comparison between the plastic film covering technique and straw coveting technique in seeding and seedling culture ofDiospyros kaki Linn in autumn .It concludes that using plastic films to cover the seeds of Diospyros kaki Linn could improve the germinating rate 33%, the germination time could be advanced 20d, and the rootstock, height and root length of the seedlings could be increased to 33.1 cm,0.29cm, 9.1 cm.The seedling culture cost could be, greatly reduced. So we propose to spread the plastic film covering technique.
