我省山楂树近几年发展很快,总面积已达200万亩以上,面积最大的平邑县和费县都达12—13万亩,很多是矮化密植栽培。有些试验地和丰产园,亩产达到3000多公斤,但从面上看还存在一些问题:为了早花早果,只进行拉枝捋枝,大枝乱,小枝密;一缓再缓,光腿现象严重;株行间距小,不利于进园管理;光照不足,产量不高,树体未老先衰。为此,建议在加强土肥水管理的基础上,再注意以下几方面的管理。
Hawthorn in our province developed rapidly in recent years, the total area has reached more than 200 acres, the largest area of Pingyi County and Fei County, up to 12-13 million mu, many are dwarfing close planting.
