在毛主席革命路线指引下,几年来,我队在贺兰山麓把酸枣改造为大枣,取得一定成绩。1977年收红枣4000多斤。几年累计产量达三万多斤,支援兄弟单位枣接穗一万余根,为发展农业、改变山区面貌作了一些工作。真是“酸枣接大枣,废物变成宝”。枣树耐干旱,在山地、沙滩都能生长。大枣营养丰富,果实含碳水化合物73％,蛋白质3.3％,脂肪O.4％,和钙、磷、镁等多种营养物质。还可入中药,治病强身。枣花蜜多而浓,是重要的蜜源植物。现将酸枣接大枣的几个问题简述如下: 一、枣树枝干的构造酸枣和大枣是鼠李科,酸枣为灌木,大枣为落叶乔木或小乔木。因其亲缘关系很近,嫁接成活率高,愈合良好,生长旺盛。 Under the guidance of Chairman Mao’s revolutionary line, in the past few years, my team transformed Jujube into jujube at the foothills of Helan and achieved some success. In 1977 received jujube 4000 kilos. In recent years, the cumulative output reached more than 30,000 kilos, supporting more than 10,000 root jujube scions. As a result, some work was done to develop agriculture and change the landscape of the mountainous areas. Really “jujube pick jujube, waste into treasure.” Jujube drought-resistant, in the mountains, the beach can grow. Jujube nutritious, fruit containing carbohydrates 73%, protein 3.3%, fat O.4%, and calcium, phosphorus, magnesium and other nutrients. Can also be Chinese medicine, physical therapy. Jujube honey and more concentrated, is an important honey plant. Jujube now pick jujube several problems are summarized as follows: First, the jujube stem structure jujube and jujube rouse Branch, jujube shrub, jujube deciduous trees or small trees. Because of their close relatives, grafting survival rate, healing well, vigorous growth.
