鲁北冬枣是黄河三角洲地区稀有的宝贵果品资源。为加快冬枣业的发展,我们自1997年始进行了早果栽培技术试验。试验园设在丁庄镇王道村,面积1.2hm~2,属盐化潮土类型,pH值8.2,水浇条件良好,栽植密度1m×2m。密植园第1年结果株率80％,平均株产0.2kg,最高株产0.6kg,每666.7m~2产量达66.6kg;第2年所有植株均挂果,平均株产0.8kg,666.7m~2产量达266.4kg;1999年,666.7m~2产量达到482.4kg。早实丰产效果显著。
Lubei jujube is rare in the Yellow River Delta region of precious fruit resources. In order to speed up the development of winter jujube industry, we started since 1997, early fruit cultivation techniques. The test garden is located in Wangdao Village, Dingzhuang Town, with an area of 1.2hm ~ 2. It belongs to saline soil and has a pH value of 8.2. The watering conditions are good and the planting density is 1m × 2m. In the first year of the plantation, the plant yield was 80%, the average yield was 0.2kg, the highest yield was 0.6kg, and the yield per 666.7m ~ 2 was 66.6kg. In the second year, all the plants were fruiting, with an average yield of 0.8kg and 666.7m ~ 2 production reached 266.4kg; in 1999, 666.7m ~ 2 production reached 482.4kg. Early fruit yield significant results.
