Embodiment 1

[0019] One-year-old seedlings with a seedling height of 30 cm and a ground diameter of 0.4 cm were selected, and planted in February in a container with a size of 30 cm × 30 cm with 100% red core soil as the substrate by weight percentage, and drenched with root-fixing water. Weather conditions and the moisture status of the matrix in the container are sprayed with water, and sterilization and insecticide are routinely sprayed every week to prevent and control diseases and insect pests. After 30 days of planting, choose sunny days to use branch scissors to cut stems to promote germination. The cuts should be smooth, keep the stem height 15 cm, and keep 1 pair of leaves. Spray fungicide and water to moisturize. On the day before cutting in April, drench the matrix with 0.5% potassium permanganate solution in a black nutrition bag with a weight percentage of 100% red heart soil matrix and a size of 10 cm × 14 cm, and then soak the matrix after 4 hours. Be 500 times of liquid spr...

Embodiment 2

[0021] Select 1-year-old seedlings with a seedling height of 35 cm and a ground diameter of 0.5 cm, and plant them in February in a container with a size of 30 cm × 30 cm with 100% yellow core soil as the substrate. Conditions and the moisture status of the matrix in the container are sprayed with water, and sterilization and insecticide are sprayed every week to prevent and control diseases and insect pests. After 30 days of planting, choose sunny days to use branch scissors to cut off the stem to promote germination. The cut should be smooth, keep the stem height 20 cm, keep 1 to 2 pairs of leaves, spray fungicide and water to moisturize. On the day before the cutting in May, the black nutrient bag with a weight percentage of 100% yellow core soil and a size of 10 cm × 14 cm was drenched with a 0.6% potassium permanganate solution, and then used after 4 hours. Percentage by weight is 50% carbendazim wettable powder 800 times of liquid spraying stand-by. Select semi-lignifie...

Embodiment 3

[0023]Select 1-year-old seedlings with a seedling height of 40 cm and a ground diameter of 0.6 cm, and plant them in a container with a size of 30 cm × 30 cm with 100% yellow core soil as the substrate in March, and pour enough rooting water, depending on the weather during the period. Conditions and the moisture status of the matrix in the container are sprayed with water, and sterilization and insecticide are sprayed every week to prevent and control diseases and insect pests. After 30 days of planting, choose sunny days to use branch scissors to cut off the stem to promote germination. The cut should be smooth, keep the stem height 20 cm, keep 2 pairs of leaves, spray fungicide and water to moisturize. On the day before cutting in June, drench the matrix with 0.8% potassium permanganate solution in a black nutrition bag with a weight percentage of 100% yellow heart soil substrate and a size of 10 cm × 14 cm, and then use it 4 hours later. Percentage by weight is 50% carbend...

Abstract

A cutting propagation method of Michelia macclurei includes the steps: stock plant planting and management, cutting medium sterilization, cutting collection, hormone treatment, and cuttage and post-cuttage management. The method is characterized in that high-quality seedlings are transplanted into medium-containing containers to cultivate cutting stock plants, trunks are cut to promote sprouting, cutting medium is sterilized, high-quality cuttings are treated and placed and cultivated in a sun shed, and high-quality cutting seedlings of Michelia macclurei are obtained. The method has the advantages that a cutting propagation method of Michelia macclurei is provided, cuttings are high in quality and availability, few pest and disease damages occur, survival rate is high, the seedlings can be directly taken out of a nursery for foresting, the effective and reliable method is provided for germplasm resource genetic diversity and germplasm resource conservation for Michelia macclurei, the requirements of China for precious tree species resources are met, and great economic benefit and social benefit are achieved.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a cutting propagation method of Huolinan. Background technique [0002] Fire Nan ( Michelia macclurei Dandy ) is an evergreen tree of the genus Michelia in the Magnoliaceae family, with a straight trunk, up to 30 meters high, neat and beautiful tree shape, dense branches and leaves, emerald green, and fragrant flowers. Huolinan is naturally distributed in Guangdong, Guangxi, and Hainan. It likes warm and humid climate and deep acidic soil. It is mostly distributed vertically in hills below 600 meters above sea level. Huolinan is resistant to drought and barrenness, has strong germination ability, rapid growth, and long life (more than 100 years); Huolinan has the characteristics of high yield rate, excellent material, not easy to deform, and free from insects. It is widely used in high-end furniture, handicrafts, industries such as plywood and construction. ...
