我场有十五年生本地早(构头橙砧)2273株,生势旺盛,但大部不结果,少数结果的产量也不高。我们曾采用停施氮肥,摘除六月梢,利用水平枝或下垂枝等方法均未收到效果。1973年试用环剥及结扎法处理,有效地促使不结果本地早开花结果了,一般单株产果30—50斤,最高一株80斤。我们环剥90株,结扎30株,共120株,总产4500斤,外销率70%以上;而未处理的仍然结果极少或不结果。具体做法;环剥:一般在4—6月间进行,以盛花期较适时。主要在侧枝上选择3—5厘米直径的大
There are 2273 local early (Anvil anvil) horns in my field of 15 years old, which are experiencing strong growth but most of them are not fruitful yet the yield of a few results is not high. We used to stop nitrogen fertilizer, removal of June shoots, the use of horizontal branches or drooping branches and other methods have not received any results. 1973 trial girdling and ligation method to effectively promote fruitless local results early flowering, the general fruit yield of 30-50 kg per plant, a maximum of 80 kg. We girdle 90 strains, ligation 30, a total of 120 strains, a total output of 4500 pounds, the export rate of 70% or more; and untreated still with little or no result. Specific practices; Girdling: usually carried out between April and June, in order to flowering more timely. Mainly selected in the collateral 3-5 cm in diameter
