在长期栽培条件的影响下,金丝小枣一般需要15年生左右方能进入开甲结果期,加之多习惯于稀植,因而造成了小枣结果迟、产量低、受益晚。目前,全省枣树平均单株产量仅6斤左右,沧州地区小枣平均单株产量也不超过8斤。为解决金丝小枣生产中存在的问题,我们于1977年开始了小枣矮化密植试验研究,取得较好的效果。1980年四年生小枣树亩产鲜枣414斤,相当于全省枣树平均亩产的两倍;1981年亩产鲜枣943.5斤,较1980年增产128％。现将丰产栽培技术简介如下:
Under the influence of long-term cultivation conditions, Jizo jujube generally takes about 15 years to enter the fruiting period, coupled with more accustomed to thin planting, resulting in the jujube results late, low yield, benefit late. At present, the province’s average yield of jujube only about 6 kg, jujube Cangzhou average yield per plant does not exceed 8 pounds. In order to solve the problems existing in the production of Watkins jujube, we started the experiment of jujube dwarfing close planting in 1977, and achieved good results. In 1980, jujube tree jujube yield 414 kg per mu, equivalent to twice the average yield of jujube trees in the province. In 1981, mu yield of fresh dates 943.5 kg, an increase of 128% over 1980. Now the high yield cultivation techniques are as follows:
