Cerebella cultivars

First, the breeding and cultivation of borneol

Dragon's beetles use Daejeon cuttings to survive more than 80% of the seedlings, and November is the best. The dwarf forest branching operations can be harvested year after year for continuous use, and the processing is pollution-free.

1. Cutting method

The cutting sites can be selected from the margins of forests or forests with good microclimate. The cutting bed can be made into bricks with a height of 60 cm in the east, 40 cm in the west and 315 meters in width (depending on the terrain). In the center of the bed, a deep 40 cm deep and 40 cm wide was communicated to the seedbed, and the gully was filled with gravel to form a turtleback. Inserted into red soil alluvial soil, 20 to 25 cm thick. Disinfect with 0.2% potassium permanganate one week before cutting and cover it with a film. A 2-meter-high fixed shade shed is set on the insertion bed, and the light transmittance is about 30% to 40%. For ease of transplanting, nutrient cuttings can also be used.

The cutting time is from March to early April in the south. Prematurely, due to low temperature, the incision at the base of the cuttings becomes dark, which unfavorably heals and roots. If the temperature is too late, the cuttings can not be healed and the nutrition is consumed, which is also not conducive to healing and rooting. Cuttings are best used for 2 to 3 years of borneol seedlings. The base of the cuttings was cut into smooth and flat mouths by the joints, and the top was cut off from the section 0.13 to 0.15 cm with a slanting mouth, leaving one bud per leaf. Cuttings before cuttings were soaked with β-butyric acid or β-naphthaleneacetic acid.

The cuttings are 3 to 4 cm apart and the spacing is 10 to 12 cm. The cuttings are inserted into the soil. Press tightly after insertion, spray water wet, and cover the plastic film. Spray 2 to 4 times daily before healing, healed to rooting period 1 to 3 times a day, rainy days can be carried out every other day. Seedbed should pay attention to ventilation, air humidity control in more than 80%, the temperature should be controlled below 29 °C.

When the cuttings grow 3 to 4 new leaves, the plastic film can be removed timely for normal management of seedlings. Usually we should pay attention to weeding and insect control, and spray water in time when drought occurs. In early March of the following year, when the seedlings grow to a height of 40-60 cm, they can be excavated and planted.

2. Tissue culture method

Take the young shoots of the larvae after harvesting, cleanse them with washing, and rinse with tap water several times. Under aseptic conditions, immersed in 70% ethanol for 30 minutes, then sterilized in 0.1% Hg solution for 7 to 10 minutes, washed repeatedly with sterile water several times, and cut about 0.5 cm buds with a scalpel as the culture. material.

The above culture materials were placed on MS medium with 0.8% agar and mass fraction of 3% sucrose at a temperature of 25°C to 2°C, and the stems were thickened for about one week, and a certain amount of healing occurred at the incisions. Injured tissue, axillary buds proliferate and begin to sprout. About 1 month later, adventitious shoots can be elongated to 2 to 3 cm. Subsequent cultures were carried out in the corresponding culture medium to induce clustered shoots and roots. Before transplanting, the root culture medium was washed and planted in plastic seedling trays filled with rock and sprayed with fresh water. After 1 week, the nutrient solution can be sprayed to gradually enhance the light. After 3 weeks, the seedlings were transplanted into the soil to grow into strong borneol plantlets.

Second, the cultivation and management of borneol

The borneol forests should be built on low-lying hills or hills of red soil, and should have better water sources for irrigation. After the forest land is selected, all the shrubs shall be removed to remove all shrub weeds, and planting holes with a depth of not less than 30 cm shall be digged at a spacing of 1 meter and 1 meter. Each hole can be properly applied farmyard manure and a small amount of calcium magnesium phosphate fertilizer as a base fertilizer. Seedlings are one-year-old borneol and strong seedlings, planted in early March. After planting, nursery should be carried out in a timely manner to eradicate the breeding shrub weeds at any time, and 0.2 kg of compound fertilizer and urea can be applied to each plant during the growing season. Volcanic water spray in time, and cover mango, dry grass and other moisturizing. In the year of planting (or leap year), the main buds of the main shoots can be removed, causing the base to sprout and produce branches, dwarfing the tree. Camphor tree diseases and insect pests are dominated by scale insects, cockroach bees, and cockroaches. 90% trichlorfon or 80% dichlorvos or 40% dimethoate emulsion can be sprayed with 2000 times.

From the second year of colonization, harvesting is conducted every year from July to December to extract volatile oil. After harvesting, the forest should be cleared of miscellaneous trees in time, and weeding, ripping, and fertilizing operations should be carried out so that Lironopsis eucalyptus can continue to sprout.
