为了落实伟大领袖毛主席关于“备战、备荒、为人民”的指示,认真贯彻“以粮为纲,全面发展”的方针,近年来,张家口地区万全县板山大队以阶级斗争为纲,坚持党的基本路线,深入开展“农业学大寨”的群众运动,在搞好粮食生产的同时,除利用野生酸枣嫁接大枣外,还用酸枣核播种育苗获得成功。现将其具体作法介绍如下。一、种子处理:秋季采集野生酸枣,沤于缸中,3-5天后将果肉和果皮搓掉,淘洗干净。每百斤酸枣可取核65-70斤。将枣核浸泡于冷水中,每天换水1次,约浸泡3-5天。经常检查,如核内潮湿即可捞出进行秋播。另一种方法是把淘洗干净的枣核种子,置于不会冻裂的容器(木盒或木桶) 内,或在地上挖坑进行冰冻处理,翌年春季开冻后取出种子,拌以湿砂,湿度要比处理其它种子较大,砂与种的比例为2:1或3:1,拌好后置于阴凉地方待播。 In order to implement Chairman Mao’s guiding principle of “preparing for war, preparing for famine and serving the people” and conscientiously implement the principle of “taking grain as the key link and all-round development”, in recent years, the Banchuan Brigade of Wanquan County in Zhangjiakou region has taken the class struggle as the key link and upheld the party Depth development of the “agricultural learning Dazhai” mass movement, do a good job in food production at the same time, in addition to the use of wild jujube grafted jujube, but also with the jujube seed sowing success. Now its specific practices are as follows. First, the seed treatment: Wild collected wild jujube, 沤 in the tank, rub the flesh and peel 3-5 days later, wash clean. Per kilogram of jujube desirable nuclear 65-70 pounds. Soak the jujube in cold water, changing the water every day for about 3-5 days. Often check, such as the inner nuclear wet fish out for autumn. Another method is to pan clean the jujube seed, placed in a container (wooden box or barrel) will not be frozen, or pitted on the ground for freezing, the spring of the following year after the spring to remove the seeds, mix Wet sand, humidity greater than the treatment of other seeds, sand and species ratio of 2: 1 or 3: 1, mix well placed in a cool place to be broadcast.
