Description

Bupleurum cultivation method

Technical Field

The invention relates to a method for cultivating medicinal plants, in particular to a method for cultivating bupleurum.

Background

Radix bupleuri is a common Chinese medicinal material. Has long application history, and has the functions of relieving fever, soothing liver and invigorating yang. It is a common herb in the home. Bupleurum root is wild.

Detailed Description

Embodiment 1, a method for cultivating bupleurum includes land selection and preparation, propagation, field management, pest control, harvesting and processing, and bamboo is planted according to the following method:

2. propagation, namely seed propagation, and two propagation methods are adopted; (1) seed selection and seedling raising: seeds are picked from the plants more than 2 years old, full and mature seeds are selected, 1000 times of carbendazim is used for soaking the seeds for 10 to 15 minutes before the seeds are planted, or soaking the seeds in water at 60-65 deg.C for 2 hr, sowing or drilling in late 3 months on the prepared furrow surface, making grooves on the surface of the furrow, uniformly spreading the seeds on the surface of the furrow, drilling, ditching and spreading the seeds according to the line spacing of 10 cm, covering the seeds with the screened fine compost and fine soil in a mixed manner, wherein the thickness is 0.5-1 cm, then watering small water, and covering the wheat straws to preserve soil moisture; or covering with mulching film, transplanting when the root head is 2-3 mm long and the root is 5-6 cm long before and after 5 months, watering the seedbed before transplanting, then digging out seedlings, selecting strong seedlings without germs, planting at any time, planting the seedlings with the row spacing of 25 cm and the plant spacing of 10 cm in a zigzag manner at fixed planting acupuncture points, and watering immediately after planting; (2) directly sowing seeds, namely sowing seeds in spring from 3 late ten days to 4 middle ten days in the spring, sowing seeds in autumn for 10 months, sowing seeds on the prepared furrow surface according to the row spacing of 10 cm multiplied by 25 cm, wherein the sowing amount is 650-700 g/667 square meters, applying 3000 kg of compost or 20 kg of calcium superphosphate every 667 square meters before sowing, slightly suppressing after sowing, covering soil for 0.5-1 cm, and covering a small amount of wheat straws or rice husks on a seedbed for preventing ground drying so as to be beneficial to the growth of seedlings;

3. field management, (1) soil loosening and weeding: the seedlings generally emerge in 30-35 days in spring sowing, and do not emerge in the current year in autumn sowing; radix bupleuri is weak in seedling stage, and weeds should be removed timely, and the weeds should be removed every 10 days for 1 time until 7 months. Weeding is combined, and soil loosening is carried out; (2) fertilizing: 150-200 kg of liquid dung can be applied to 667 square meters, or the fertilizer is applied outside the root by using 1% calcium superphosphate solution, every: spraying for 1 time in 10-15 days, and continuously spraying for 2-3 times, thereby increasing the yield. Not to apply too much nitrogen fertilizer; (3) removing tillers and picking buds, enabling overground parts of radix bupleuri to grow vigorously, enabling half of 1 year plants to bolt and flower, enabling 2 years plants to bolt and flower, enabling flowers to last for 40-50 days (from 8 th to 10 th), and timely removing newly grown buds and flower shoots in order to promote root growth; (4) and irrigation and drainage: proper water spraying is needed in the seedling stage to keep the humidity, irrigation is not needed in the growth period except for drought, and drainage of stagnant water is needed in 7-9 months of rainy season;

4. and (3) pest control: root rot, and soil disinfection before planting; a root rot nematode disease control method is characterized in that 80% dibromochloropropane missible oil is diluted by 100-150 times for 1-1.5 kg per 667 square meters during soil preparation, and sowing is carried out after application for half a month; the aphid control method comprises the following steps: spraying 1500-2000 times of 40% dimethoate emulsifiable solution 1 time every 7 days for 2-3 times; the prevention and treatment method of the yellow butterfly comprises the following steps: artificially catching adults, or spraying 200 times of the liquid of the green insect fungus to prevent and control larvae;
