山核桃是浙江特产,树林寿命长,结果早,一般栽后4~5年结实,10年后进入盛果期,而且其适栽地不与农业争地。山核桃种植投资少,收益大,一般可旱涝保收。但有一些农户因管理不善,导致山核桃产量低,经济效益下降。现简述山核桃丰产技术措施如下。1.改土整地改土可从根本上改变山核桃林生长条件。整地改土要根据原山核桃株行距是否合规格,以及不同树龄,不同地势而定。一般原株行距 Hickory is a specialty of Zhejiang, woods long life, early results, generally 4 to 5 years after transplanting strong, 10 years into the flourishing period, but its suitable land and agricultural competition. Hickory planting less investment, large profits, the general drought and salvo income. However, due to poor management by some farmers, the output of pecan trees is low and their economic benefits are declining. Now outlined Hickory yield technical measures are as follows. 1. Soil improvement Soil improvement can fundamentally change the hickory forest growth conditions. Soil preparation should be based on changes in the original pecan plant spacing specifications, as well as different ages, different topography may be. General original row spacing
