Cork cultivation techniques for Chinese medicinal materials
Phellodendron (yellow pineapple) is a deciduous tree of Rutaceae. It has the functions of detoxification, diarrhea, fire dampening and so on. Indications of hot and humid diarrhea, jaundice, leaching urine astringent pain, Chibai vaginal discharge, thermal toxic sores, eczema, yin deficiency, night sweats embolism; its delicate wood is the construction and the best raw materials used as furniture, it can be said that Phellodendron is a drug Wood dual-use plants. At present, there is a serious shortage of wild resources in Phellodendron chinense and it has been listed as a national first class key protected plant. The prospects for artificial cultivation are broad. First, nursery 1. Site preparation fertilization Huang Boxi warm and humid climate, wild trees grow more in sheltered mountain valleys, low hillside or near the creek. Fertility and moist humus should be selected for nursery or cultivation. The nursery should deep-flip and apply the base fertilizer to make a 1-1.2-meter-wide, 20-centimeter-high beak. 2. Seeding sowing autumn or spring sowing. The best period for spring sowing is from the Qingming to the valley before the rain; the best period for autumn sowing is before the freezing (ie, November). The washed seeds and sand were mixed and mixed in the ratio of 1:3 and buried in the pit for wintering in the open air. The first 20 days before the spring sowing in the second year, the fine sand was put into the wooden box, and the germination was placed in a warm place. After the seeds were blown, the seeds were sowed. Autumn sowing does not require seed treatment. Live broadcast before freezing. When the seeds are sown, the spacing is 30 cm and the depth is 5 cm. The sowing rate is 4-5 kilograms per 667 square meters, a little repression, pouring enough water at the bottom, and the bed cover straw stays moist. 3. Seedling management after removing 80% of the seedlings shall promptly remove the covering. When the seedling height is 10 cm, the seedlings shall be set at a distance of 15 cm from the seedlings. Weeding shall be done regularly to prevent grassland; timely watering shall keep the soil moist; after the seedlings are set, 667 square meters will be topped with farmyard fertilizer 2000 kg. Second, transplanting 1. Autumn planting or spring planting in the nursery in the year before the freezing was carried out; spring planted in the second year after the nursery spring Qing Ming to Gu Yu. According to the spacing of 1 meter and 2 meters, first dig a pit of 60 centimeters deep, then plant the seedlings, water and soil to ensure the survival, and 667 square meters of 300 seedlings are suitable. 2. Field management After 4-5 years of continuous planting, weeding shall be carried out in time to prevent grassland shortage. Weeding should be performed once every summer and autumn in 2-3 years, and 1 agro-fertilizer should be applied before winter, and 20 kg of fertilizer should be applied to each plant. Intercropping leguminous crops before being grown. In case of drought, water in a timely manner. Pest control, rust is the main disease of the leaves of Phellodendron chinense, the prevention and control method is to spray the enemy rust sodium 400 times during the onset. Spray once every 7 days, even spray 2-3 times; Aphid can use 40% Leko emulsion 2000-3000 times liquid spray. 3. Harvesting and processing Skinning can be carried out 10-15 years after planting. It is generally advisable to perform girdling in May-June, or peel off the bark in combination with logging. Remove old skin and sell it after drying; its wood can be used as a building material; Phellodendron leaves can be used to extract aromatic oils.
