多年来,枣树一直采用根蘖苗造林,不仅产苗量少,根系不完整,造林成活率也低,而且红枣的产量也低。现在山西吕梁地区林科所利用红枣嫩枝扦插育苗获得成功,解决了上述问题。其方法如下:首先,在塑料大棚或温室内铺一层水洗过筛过的河沙,厚约20厘米;选择生长健壮的当年生嫩枝,截成15厘米长的带叶插穗,浸吲哚乙酸3—5秒钟,然后插入沙床;经间歇喷雾使插穗叶面保持一层水膜,棚内温度控制在30℃左右,相对湿度90%以上,基质温度25℃,室内遮光率为80%。约30天幼苗生根后即可出棚炼苗,此时应勤洒水,防止日灼,再过约15天可出圃定植到大田。
Over the years, jujube has been using root tillering afforestation, not only less seedling production, incomplete root system, afforestation survival rate is low, but the jujube production is also low. At present, Luliang Prefecture, Shanxi Branch of the jujube softwood cuttings used to achieve success, solve the above problems. The method is as follows: First, shop in a plastic greenhouse or greenhouse with a layer of washed and screened river sand, about 20 cm thick; choose growing robust annual shoots, cut into 15 cm long cut leaves, dipindole Acetic acid for 3-5 seconds, and then inserted into the sand bed; intermittent spray to cut leaves to maintain a layer of water film, greenhouse temperature control at about 30 ℃, relative humidity above 90%, substrate temperature 25 ℃, the indoor shading rate of 80 %. About 30 days after the rooting of seedlings can shed shed refining, this time should be ground sprinkle water to prevent sunburn, and about 15 days to nursery colonization Daejeon.
