摘　　要：以 1年生美国黑核桃实生苗、嫁接苗和定植 3年的种子树、采穗树为试验材料 ,在生长期喷施不同倍数的OPAL液肥 ,结果表明 :采穗树、种子树平均树高比对照分别提高了 2 6 .13%和4 6 .15 % ;胸径比对照分别提高了 37.36 %和 2 4 .4 8% ;产穗量比对照提高了 2 8.97% ;果实饱满度比对照提高 2 0 .6 8% ;1年生实生苗、嫁接苗平均苗高比对照分别提高 2 8%和 31.82 % ,地径比对照分别提高 18.4 9%和 14 .2 8%。OPAL Liquid fertilizers with different concentrations were sprayed on 1-yr-old satus seedlings and grafting seedlings, 3-yr-old field planting seed trees and pick-off stachys tree of Juglans nigra;. The results showed that mean tree heights of pick-off stachys trees and seed trees were raised by 26.13% and 46.15% respectively, compared with the contrast, and plumpness of fruit was increased by 20.68%, while the seedling heights of 1-yr-old satus seedlings and grafting seedlings were raised by 28% and 31.82% respectively and ground diameters were raised by 18.49 and 14.28% respectively, compared with the contrast. It was concluded that spraying OPAL liquid fertilizer could produce positive effect on growth and development of American Black Walnut.
