劣质枣树高接冬枣后,当年成活率达90%,枣头枝平均生长量125厘米,树冠恢复率80%。第2年开始结果,第4年即可丰产。1.接穗的选择和准备早春萌芽前结合冬剪采集接穗,一般选芽体饱满的1年生发育枝,采后剪去其上的二次枝,每50条捆成1捆,在高燥冷凉的地沟内沙藏,温度保持在6℃左右。2.嫁接方法准备高接的枣园在萌芽前灌1次水,枣树萌芽后开始高接,即在4月下旬到5月中旬。高接时,按照小冠疏散分层形树体结构的要求,选留5～6个主枝,第1层3个,
Poor quality date jujube jujube, then the survival rate of 90%, the average growth of jujube branches 125 cm, crown recovery rate of 80%. The second year results, the first 4 years to yield. 1. Selection and preparation of scion In early spring buds combined with winter shears scion, the general election Bud full of 1 year-old development branch, cut off after its secondary branches, bundled into a bundle of 50, in the high cold Sand trench in the cold trench, the temperature remained at about 6 ℃. 2. Grafting method for the high pick the jujube Park before irrigation in irrigation water, jujube began sprouting high pick, that is, in late April to mid-May. High then, according to the small crown evacuation hierarchical tree structure requirements, choose to stay 5 to 6 main branch, the first layer 3,
