板栗育苗措施比较研究

采用大田秋末冬初畦播覆膜和未覆膜2种措施培育板栗苗木，在相同管理条件下，出苗时间覆膜早于未覆膜；出苗率覆膜高于未覆膜；年终生长量苗高、地径生长粗度、苗木整齐度、成苗率、等级和质量均大于未覆膜。通过对2种不同育苗措施的调查分析，结果表明，对板栗育苗覆膜，能明显提高苗木等级和质量，建议大力推广该法育苗，为林业生态建设和社会经济发展，提供优质壮苗。

Comparative Research on Chestnut Breeding

Two ways to produce chestnut seedlings during late fall and early winter were compared: to sow with poly film cover after and without plastic film cover after. Under the same conditions, the former treatment contributed earlier and higher germination and had a higher annual growth, bigger ground stem diameter, and evener germination than the latter treatment. To show chestnuts with poly film covered after proves to be effective to upgrade the seedling quality and standards.
