我县是长红枣的重要产区之一,但多年来由于管理粗放,产量低而质量差,为提高产量和质量,我们从1983—1985年进行了技术开发试验。 试验分设在刘家峪、毫山、杨家庄三村,共有枣树2万株,树龄15—30年生。张家峪为壤土,pH7.2.有机质含量0.7%;毫山为沙土,pH5.8,有机质含量0.28%;杨家 Our county is one of the important producing areas for long jujube. However, due to extensive management, low output and poor quality over the years, we conducted technological development experiments from 1983 to 1985 to improve production and quality. The experiment is divided into Liujiayu, Moushan, Yangjiazhuang three villages, a total of jujube 20,000, age 15-30 years old. Zhangjiayu loam, pH7.2. Organic matter content of 0.7%; mound Hill as sand, pH5.8, organic matter content of 0.28%; Yang
