New Rapid Propagation Technology for Hybrid Gastrodia: Detailed Explanation of Two Methods
I. Potted Breeding Method for Gastrodia Arrow Bud Mother Corms (Using Yidu Red Gastrodia as an Example) 1. Potted Seedling Cultivation: Around Qingming Festival, when room temperature stabilizes above 15°C, select fresh, robust, plump-budded, undamaged high-mountain wild red gastrodia arrow bud mother corms weighing 100-150 g (labeled Wild Red) and plains-cultivated red gastrodia arrow bud mother corms (labeled Domestic Red). Plant them separately in river sand in plastic washbasins or enamel basins, evenly placing 4 arrow bud mother corms (plants) per basin, with arrow buds (parrot-beak tips) facing upward and 3-5 cm from the basin edge, covering with 5-

Damage Caused by Cutworms to Reishi Mushrooms and Its Control Methods
Cutworms belong to the order Lepidoptera, family Noctuidae. They are not only an important pest of agricultural and forestry crops, but also a common pest in the cultivation of edible fungi such as reishi mushroom, silver ear fungus, wood ear fungus, and oyster mushroom. They are widely distributed, but the degree of damage varies. They occur more frequently in outdoor open-field sunken-bed cultivation and plastic greenhouses. Damage characteristics: The larvae feed on the mycelium of reishi mushrooms, inhibiting mycelial growth and affecting fruiting body formation, which reduces reishi mushroom yield and lowers quality. Morphological characteristics: Adult body length 16-23 mm, wingspan 42-54 mm

Pinellia ternata cultivation techniques (part two): detailed planting methods
(1) Propagation methods Pinellia ternata is mainly propagated by tubers and bulbils, and can also be propagated by seeds. ① Tuber propagation After Pinellia ternata has been cultivated for 2 years, the underground tubers can be dug up after the stems fall over in June, August and October each year. Select small tubers about 0.5 cm in transverse diameter that are robust and free from pests and diseases as seed. Mix the seed tubers with semi-dry, semi-moist fine sandy soil, store them in a ventilated and cool place, and take them out for planting in the winter of the same year or the spring of the next year. Planting in the spring of the next year is preferable. With a row spacing of 15 cm, open furrows 10 cm wide and about 5 cm deep, and arrange two staggered rows in each
