去年8月,河北省农科院组团到日本国红富士苹果主产区长野县,着重研修了提高富士苹果果实品质的技术措施,现将有关技术介绍如下: 一、增大果个技术 1、培肥地力。日本把培肥果园地力作为土壤管理的主要内容,土壤有机质含量一般在5%～10%之间,最高的地块可达15%以上。培肥地力的方法是通过行间种植绿肥植物,定期刈割,树下覆盖。秋季果园撒施羊粪、鸡粪等加工后的专用复合肥。 2、合理修剪。日本的富士苹果全部利用中、短果枝结果。适量轻剪,配合回缩,及时更新衰老枝组和结果枝,使结果枝龄处于2～4年生状态,并使结果部位集中于大技干
In August last year, Hebei Academy of Agricultural Sciences organized a delegation to Nagano, the main producing area of Red Fuji apple in Japan. It focused on the technical measures to improve the fruit quality of Fuji apples. The relevant technologies are introduced as follows: Fertility fertility. As the main content of soil management in Japan, soil fertility orchard fertility is generally between 5% and 10%, with the highest plots reaching more than 15%. The method of fertilizing soil fertility is to plant green manure plants in rows with regular cutting and under tree cover. Autumn orchard spread sheep manure, chicken manure and other processed special compound fertilizer. 2, reasonable pruning. Japan’s Fuji Apple all use of short and short fruit results. The amount of light shear, with the retraction, the timely update of the aging branch group and the results of branches, so that the results of the branch age in 2 to 4 years of state, and the results of the site focused on the big technical
