万县地区现有枇杷树约16万株,面积约3,000亩,其中结果树仅约2.5万株。近两年,我们对实生幼龄枇杷树进行了环割促花,初步摸索出一套有效的技术措施。使实生5年枇杷树单株平均花穗率达18.1%,最大花穗率达39.4%,最大单稳果数达14粒。这套促花技术的要点如下: 1.处理对象:应选择有较多贮备营养物质的生长健壮树,一般是主干圈长已达15厘米左右,分枝已达3级以上的实生幼树。 2.处理时期:以6月中旬至下旬期间处理的促花效果明显,4、5两个月中旬处理的效果不佳。 3.处理方法:凡主干环割1圈或2圈(相距
There are about 160,000 loquat trees in Wanxian area with an area of about 3,000 mu, of which about 25,000 trees are the result trees. In the past two years, we have carried out ring cutting and flower promotion on young live loquat trees, and initially explored a set of effective technical measures. The average spike rate per plant of eriobotrya japonica was 18.1% in 5 years. The maximum spike rate was 39.4% and the maximum number of single stabs was 14. This set of flower techniques are as follows: 1. The object of treatment: Should choose to have more storage of robust growth of healthy nutrients in the tree, usually trunk length has reached about 15 cm, branches have reached more than 3 seedlings. 2. Processing period: The flowering effect was obvious from mid-June to late treatment, and the effect of treatment in mid-April and April was not good. 3. Treatment: Where the main ring around a circle or 2 laps (apart
