为提高核桃树的育苗效率,加快核桃良种苗木的生产。2010年以来,我们在沁阳市四星林果合作社的核桃苗圃基地,开展了利用青皮核桃直接育苗试验,取得了出芽率90%以上,嫁接成活率90%以上,当年出苗,当年嫁接,翌年冬季出圃,平均苗高达到80厘米,最高可达200厘米,栽后第2年即可结果的良好效果。为大面积生产性培育核桃优良苗木提供了技术参考。现将核桃树快速育苗新技术总结如下。1苗圃地选择应选择光照充足,地势平坦,排灌方便,交通比较便利的地块,要求土壤疏松肥沃,壤土、沙壤土均可,
To improve the nursery efficiency of walnut trees, speed up the production of walnut seedlings. Since 2010, we have carried out the direct seedling experiment using peel of walnut in Qinyang City based on the base of walnut nursery in Qinyang City, and achieved budding rate of over 90% and grafting survival rate of over 90%. In the same year, Winter nursery, the average seedling height of 80 cm, up to 200 cm, 2 years after planting can result in good results. For large-scale production of walnut fine nursery stock provides a technical reference. Walnut tree is now a fast seedling new technology is summarized as follows. 1 nursery to choose a sufficient choice of light, flat terrain, irrigation and drainage convenience, traffic more convenient land, requires loose and fertile soil, loam, sandy loam can be,
