酸枣又称五眼果(Choerospo-ndias axillaris(Roxb)Burtt),生长迅速,用途广。临海县白石大队栽植的一块4年生幼林,均高6.7米、胸径6.8厘米,其生长量大大超过同一立地条件的同龄杉木、苦楝等速生树种,是一个理想的荒山造林和四旁绿化树种。但由于种源限制,播种苗不能满足生产需要。1978年进行了酸枣根插育苗试验,收到显著效果。1年生根插苗,平均高210厘米,根径2.4厘米,最高达285厘米,根径3.1厘米,分别比同龄播种苗增长10%和19%。根群亦较播种苗发达。现将方法简介如下:
Jujube, also known as five fruit (Choerospo-ndias axillaris (Roxb) Burtt), rapid growth, wide range of uses. A 4-year-old young plantation planted by the Whitehead Brigade in Linhai County, both 6.7 meters high and 6.8 cm in diameter, has an ideal growth rate for afforestation and afforestation on all sides with the same growth rate of Chinese fir and neem. However, due to provenance, sowing seedlings can not meet production needs. In 1978 carried out the jujube root inserted seedling test, received significant results. One-year-old root seedlings, an average of 210 cm high, 2.4 cm in diameter, up to 285 cm, diameter 3.1 cm, respectively, than the same age sowing seedlings increased by 10% and 19%. Roots also developed than sowing seedlings. Now the method is as follows:
