枣是我国的重要果树,集中产区的产品收益常占农业总收入的40～60％,对产区经济具有重要意义。然而,目前多数产区平均株产鲜枣仅5kg左右,仅及丰产她片的20～25％。为了尽快提高我国枣树生产水平,作者以多年调查研究资料为基础,全面分析了我国枣区的低产原因,将近年山东、河北、河南、湖南等省大面积增产技术和山西、安徽等省丰产技术研究综合成一套适于我国南、北方枣区应用的增产技术,供各枣区参考应用。这套技术在一些枣区大面积应用,三年中,投资不多,树势普遍由弱转强,产量增长2～4倍,平均单株产量上升到30～40kg以上,表现出良好的效果。
Jujube is an important fruit tree in China. The yield of the products in the concentrated producing areas often accounts for 40-60% of the total agricultural income, which is of great significance to the economy of producing areas. However, at present, the average yield of fresh jujube in most producing areas is only about 5 kg, only 20 to 25% of the high-yielding tablets. In order to improve jujube tree production in China as soon as possible, the author based on years of investigation and research data, a comprehensive analysis of the reasons for the low yield of jujube region in our country in recent years, Shandong, Hebei, Henan, Hunan and other provinces large-scale production technology and Shanxi, Anhui Province, Technology research into a set of integrated into the southern and northern regions of China jujube application of production technology for reference for the jujube area. This technique has been applied extensively in some jujube regions. In the three years, the investment is small and the shrub vigor generally changes from weak to strong, with the output increasing 2 to 4 times. The average yield per plant has risen to more than 30 to 40 kg, showing good results .
