Background
Yichang Machilus is plant of Machilus of Lauraceae, evergreen arbor, slender and short small branch, conic inflorescence, nearly spherical, black fruit and small tip; the fruit stalks are not enlarged. The flowering period is 4 months, and the fruit period is 8 months. China has special species, and is distributed in Hubei, Sichuan, southern Shaanxi and Western Gansu of China. Grown in the sparse forest of hillside or valley with the altitude of about 560 and 1400 meters. Can resist extreme low temperature of-10 ℃ and high temperature of 40 ℃.
Yichang Machilus is an excellent greening tree species, the tree shape is good, the trunk is straight, the tree posture is beautiful, and the green onion is heavy. The leaves are semi-tanned and evergreen in four seasons, and the young shoots are light red in spring and autumn after 3-4 times of young shoots per year. The tree shape, the trunk and the leaves have good landscape effect. The beautiful posture is an important characteristic of the nanmu as a garden tree species, and the nanmu can be reasonably applied according to the external form of the Yichang Machilus in combination with the actual situation when being applied. The Yichang Machilus is widely applied to greening of roads, parks, residential areas and plant areas in the form of planting in solitary, row or group planting.
The Yichang Machilus wood has moderate density, stable wood property, corrosion resistance, light color, fine texture, beautiful luster and light fragrance, is ancient and modern, has no praise and is an excellent product in wood. The added value of the product is higher in deep processing. The leaves can be used for extracting aromatic oil, the oil content of the seeds is high, and the oil can be used for preparing soap and lubricating oil. The Yichang Machilus are planted in large area, the landscape is beautiful, and the Yichang Machilus can also become a green bank. The method is suitable for the Chang Machilus kuntze industry, and for the planting of Chang Machilus kuntze and the deep processing of Machilus kuntze. Can increase income, beautify environment and create new thinking and new fields.
Because of these characteristics of the phoebe machani, recently, the demand for phoebe machani seedlings is large. At present, the cultivation of the Machilus yichang seedling mainly depends on seeding propagation, but the propagation mode is easily influenced by hybridization, so that the self characteristics of the plant line are not easily maintained, and the propagation period is long.

collecting cuttage branches, collecting branches of the photinia changchang in 8 months on a hillside with the altitude of 1200m near a Guanmen mountain laboratory of the Shennong national park, selecting semi-lignified twigs of the current year as cuttage branches, shearing the cuttage branches into 10cm, and reserving a bud point or 2-3 blades; the specific method for cutting the cuttage branches comprises the following steps: cutting the stem of the Machilus wilsonii at the position 1-2cm away from the bud point or the leaf at the upper end of the cuttage branch and vertical to the central line direction of the Machilus wilsonii rhizome; obliquely cutting off the stem of the photinia changii at the lower end of the cuttage branch, and keeping an oblique angle of 15 degrees between the plane of the scissor opening and the central line of the cut rhizome of the photinia changii;
and step three, immersing the lower oblique port of the cuttage branch into a nutrient solution for 2 hours, and then inserting the cuttage branch into nutrient soil.
In the cutting seedling method of the Yichang Machilus, the nutrient soil is prepared by mixing soil and sand according to the volume ratio of 2:1, and the nutrient soil is paved on a seedbed after sterilization. Soil with deep soil layer, rich soil and rich humus is selected around a Shennongjia national park officer mountain laboratory, is uniformly stirred and sterilized according to the volume ratio of 2:1 of the soil to sand, and is paved on a prepared seedbed. The selected soil is exposed to the sun in the burning sun to remove pest eggs in the soil, then carbendazim is sprayed to sterilize, and sand is sterilized by high-pressure steam to avoid the condition that the seedlings are infected with germs.
In the cutting seedling method of the Yichang Machilus, the nutrient solution contains 50mg/L IBA.
In the cutting seedling method of the Yichang Machilus, the length ratio of the overground part to the underground part of the cutting branch is 1: 2.
the cutting seedling method of the Yichang Machilus comprises the following steps:
and step four, watering the cuttage branches after cuttage, not needing to rush too fast, stopping watering when water is found to just seep out of the bottom of the flowerpot, so that each inch of soil in the flowerpot can be moistened by the water, covering a seedbed with a film to keep the moisture after the water is thoroughly watered, and then building a sunshade with the transmittance of 65% on the seedbed.
In the cutting seedling method of the Yichang Machilus, the nutrient soil is laid in flowerpots, 20-30 cutting branches are inserted into each flowerpot, and the distance between every two adjacent cutting branches is 3-5 cm. A plastic flowerpot with four holes at the bottom of a pot with the diameter of 26cm and the height of 20cm is selected for cuttage of Yichang Machilus. Utilize the flowerpot as cuttage and the earlier stage of seedling to cultivate, can make the cuttage branch go on relatively independently in the flowerpot, be difficult to appear infecting the condition of germ, cross infection also is difficult to appear, and the seedling survival rate is high, and simultaneously, flowerpot and seedling are easy to be separated, and the seedling plays the seedling easily, and the root system remains completely, more does benefit to the seedling later stage and grows.
