近几年,我国苗木需求量相对减少,苗木需求的质量却越来越高,苗木产品结构性余缺并存的现象依然十分严重。苗木生产如何适应市场需求,减小余缺并存的矛盾,有针对性的加强冬季苗圃管理,及时培育当前需求的苗木,填补市场空白,是冬季苗圃管理的重点。当前,我国北方有较大需求且市场紧缺、价格较高的苗木是干直圆满、无死结伤疤、有二级以上分枝全冠帽圆的大规格一级苗。如米径12~20cm的国槐、白蜡、法桐、元宝枫、栾树、垂柳、银杏等乔木,地径6~10cm的高干樱花、
In recent years, the relative reduction in demand for seedlings in our country, the quality of the demand for seedlings is getting higher and higher, the phenomenon of the coexistence of structural defects in seedling products is still very serious. How to adapt to the market demand seedling production, reducing the contradiction of the coexistence of the remaining, targeted to enhance the management of winter nurseries, timely nurturing the current needs of seedlings to fill the gaps in the market, winter nursery management focus. At present, there is a big demand and the market is scarce in the north of our country. The seedlings with higher price are perfect, no dead knot scars and large-sized first-class seedlings of more than two branches with full crown caps. Such as the diameter of 12 ~ 20cm Sophora japonica, ash, Fatong, Acer truncatum, Golden Luan tree, weeping willow, ginkgo and other trees, ground diameter of 6 ~ 10cm high dry cherry,
