大枣素有木本粮食之称。抗旱耐瘠薄,且经济价值高,是干旱丘陵区造林首选树种。但由于该区水源缺乏,干旱少雨,大枣大苗移栽成活率低,投资大,因此于1997年用营养杯酸枣亩造林10公顷,1998年全部进行大枣嫁接,成活率97%,不仅造林投资少,且幼树生长势良好。一、营养杯苗培育 1997年春,培育营养杯酸枣苗。营养杯用塑料薄膜制成直径6—8厘米,高15厘米的容器,底部打孔,栽植时要破袋。也可用旧报纸制作,底部不打孔。栽植时不用破袋。营养土用2份菜园土,1份细沙土,1份腐熟有机肥充分混匀过筛后制成。将营养土装入营养杯中,墩实,营养土距杯口2厘米为宜,然后将杯整齐地摆 Jujube vegetarian known as woody food. Drought-resistant barren, and high economic value, is the preferred species of afforestation in arid hilly areas. However, due to the lack of water and drought in the area, the transplanting of jujube seedlings has a low survival rate and a large investment. Therefore, 10 hectares of acacia were planted in 1997 with jujube nutrition cup. In 1998, all jujube grafts were grafted with a survival rate of 97% Little investment, and saplings grow well. First, the nutrition cup seedling cultivation The spring of 1997, cultivating cup nutrition jujube seedlings. Nutritional cup made of plastic film diameter 6-8 cm, 15 cm high container, the bottom of the hole, planting bags to be broken. Also available in old newspapers, the bottom is not perforated. Do not break bags when planting. Nutritional soil with 2 parts of garden soil, a fine sand, a rotten organic fertilizer fully mixed sieve made. Nutritional soil into the nutrition cup, pier solid, nutrient soil from the cup mouth 2 cm is appropriate, and then the cup neatly placed
