Embodiment

[0020] Embodiment: select Zhanhua Dongzao variety to carry out hard branch cutting seedling raising

[0021] 1. Collection and storage of seed strips

[0022] 2 months before germination, collect the jujube first branches that are healthy, well-developed, and free from diseases and insect pests, and cut them into 18-22cm cuttings with 3-4 nodes at the place where the buds are full in the lower part, and cut them horizontally 1cm from the top node. , the lower end is cut into a single horse-ear shape at 2-3cm below the base joint, and 50 pieces are bundled into a bundle; for immediate sand storage, use clean wet river sand in the shade, pave the ground with a thickness of 10cm, and then place the bundled cuttings vertically On the sand surface, after laying out a layer, cover the cuttings with clean wet river sand to fill up the gaps between cuttings, and then cover with a layer of wet river sand with a thickness of 5cm. After placing 5 layers of cuttings repeatedly, the top la...

Abstract

The invention relates to a novel technology for raising hard-rooting fruit tree cutting seedlings, in particular to a jujube tree hardwood cutting seedling raising method. The method mainly comprises the following steps: cutting acquisition and shearing, cutting sand storage, field selection and land preparation, plastic house establishment, high ridge bedding, cutting treatment and cutting, ground film covering, seedling management strengthening and finished product seedling obtaining. By adopting the plastic house, the covering ground film for temperature rise and hormone treatment, the invention has the advantages that the cutting callus formation and rooting are promoted, the survival rate is high, the seedlings can be obtained in the year of cutting, the labor and the time are saved, the period is short, the cost is low, the effect is taken quickly, the yield is high, the jujube tree seedling raising technology is advanced and the rapid development of Chinese jujube trees is certainly promoted.

Description

technical field [0001] The invention relates to a new technique for growing seedlings by cuttage of difficult-to-root fruit trees—a method for raising seedlings by cutting hard branches of jujube trees. Background technique [0002] Jujube has strong adaptability to climate and soil, and is resistant to drought, waterlogging and alkali. It is a famous forest-grain intercropping tree species in the North China Plain. In recent years, with the continuous introduction of new fine jujube varieties, the cultivation area has increased rapidly, especially with the great development of Xinjiang Zaoshu New District, the demand for seedlings is increasing. Jujube is a tree species that is difficult to take root from cuttings. The conventional seedling raising techniques are root tiller seedling raising and grafting seedling raising. The seedling raising period is long and the cost is high, which cannot meet the production needs. Hardwood cuttings are difficult to take root and surviv...
