What are the control methods for underground pests of licorice?
The main underground pests at the seedling emergence stage of licorice are mole crickets and the Oriental beetle (He's Oriental chelifer), while at the mature plant stage the main ones are click beetles, scarab beetles, cutworms and darkling beetles, which cause serious damage. After wild licorice is damaged by underground pests, because the wild root head is deep below the soil surface, it is mainly the underground stem that is eaten and damaged, and after damage the adventitious buds can grow rapidly and regenerate, so the whole plant does not die. In contrast, what is mainly eaten and damaged in cultivated licorice is the root, and the plants are young and small with weak recovery ability; accompanied by rot infection, this often leads to the whole plant rotting and dying.

Detailed Explanation of Gastrodia Planting Methods and Key Technical Points
① Asexual propagation cultivation method: The planting method that uses the tubers of Gastrodia as propagation material is called the asexual cultivation method. ② Active fungal wood plus new wood companion planting method: Dig pits according to the specific conditions of the planting site. The pit width should be 6-8 cm wider than the length of the fungal wood. The pit length is not fixed; it is suitable if 5-20 pieces of fungal wood can be placed. The pit depth depends on local conditions. Loosen the pit bottom by 6-10 cm and shape it into a slope, then the fungal wood can be laid out and Gastrodia planted. ③ Sexual propagation method: The planting method that uses seeds as propagation material is called the sexual propagation cultivation method. The white-headed hemp and rice hemp produced by seed propagation are used as seed tubers. They have strong vitality, are not easily degraded, and have a large propagation coefficient, making this an important approach for cultivating Gastrodia.

Fertilization Methods for Gastrodia: Can Diammonium Phosphate, Superphosphate, and Ammonium Nitrate Be Applied?
Yes, they can be applied. This is because all three fertilizers are acidic fertilizers and can increase soil acidity. In terms of their properties, they suit the growth and development requirements of Armillaria mellea and Gastrodia; in terms of composition, all three fertilizers contain phosphorus and nitrogen components; in theory, Armillaria mellea requires a certain amount of phosphorus and nitrogen during its growth and development. During the growth and development of Gastrodia, as it absorbs water from the substrate, it can take up some trace elements and phosphorus along with the water. Therefore, when cultivating Gastrodia, applying an appropriate amount of acidic fertilizer can increase Gastrodia yield. According to Dan Cunzhi and Wang Yingkui, Gastrodia specialists in Wangjiayuan Village, Siping Township, Danfeng County, Shanxi Province

How do Gastrodia elata cultivation methods affect Gastrodia elata yield?
Choosing good planting methods for the tubers is also one of the important measures for increasing Gastrodia elata yield. Box cultivation and pit cultivation of Gastrodia elata overwintered in double-layer plastic sheds can significantly increase yield. Because the double-layer plastic shed uses sunlight as its energy source, it greatly increases Gastrodia elata yield. According to trials by the Institute of Special Animal and Plant Sciences of the Chinese Academy of Agricultural Sciences, using a double-layer plastic shed to overwinter box-cultivated Gastrodia elata inside the shed, Shaanxi seed stock increased in weight by 27.4 times, and local Jilin seed stock increased in weight by 99.8 times. If there is heating equipment indoors, using wide-mouth bottles and plastic bags to cultivate Gastrodia elata

What are the methods for selecting Gastrodia elata fungus strains and Gastrodia elata seeds?
1. Armillaria mellea: Some Armillaria mellea varieties are high-yielding and high-quality, while some varieties instead harm and feed on Gastrodia elata, so farmers must be cautious when introducing strains. Our company promotes the Armillaria mellea a-9 variety, selected by the Institute of Medicinal Plant Development, Chinese Academy of Medical Sciences, from numerous varieties at home and abroad. Large-scale application and promotion have shown that this variety has strong vitality, dense branching, a high colonization rate, high yield, and high quality, making it the preferred superior variety for cultivating Gastrodia elata. 2. Germination fungus: The germination of Gastrodia elata seeds must rely on the infection of the embryo by fungal hyphae of a Mycena species to provide

Cultivation Methods and Technical Key Points for Gastrodia Seed Material
Gastrodia cannot nourish itself; it must rely on a symbiotic relationship with Armillaria mellea (honey fungus) to obtain nutrients for reproduction and growth. The parasitic Armillaria mellea can grow on about 200 species of tree trees, especially broadleaf forests. Generally, Armillaria mellea grows from the roots of cut trees, bamboo, or burned trees and bamboo, as well as dead trees fallen in the forest. Armillaria mellea must grow vigorously under certain moist conditions; soil moisture content should be no less than 45%-50%, and relative air humidity of 75%-80% is suitable. Armillaria mellea can also be cultured artificially, but the spawn must first be

How to Grow Honeysuckle? A Complete Guide to Methods and Techniques
I. Cultivation Methods (1) Seed propagation. Seeds collected in autumn can be sown immediately or stored until early April of the following year. Both broadcasting and drilling are acceptable. Apply 750-1000 kg of farmyard manure per mu as base fertilizer. Before sowing, soak the seeds in 25°C warm water for 24 hours to promote germination, and sow after the seeds show white sprouts. When the seedlings are about 6 cm tall, combine intertillage weeding and thinning with 1 topdressing of 10% urea solution. When the seedlings are 10 cm tall, spray 1 application of 200-fold Bordeaux mixture; they can be lifted from the nursery and transplanted in 30-36 days.

How to plant honeysuckle? Planting methods and key technical points
I. Planting method: Use sunny barren slopes, sandy land, terrace edges, and riverside sites to plant honeysuckle. Apply 2000-3000 kg of organic fertilizer per mu. Layering can be done in both spring and autumn; in autumn, late August to mid-October is best. Choose strong 1-2 year old branches for layering, 50-80 cm long; after covering with soil, tread it firm, leaving 2/5 of the layer exposed above the soil surface, and water promptly in case of severe drought. Honeysuckle begins to root in 15 days, and is then transplanted for field planting in the following spring or autumn. II. Field management (1) Cultivation and weeding. Cultivate and weed 3

Goji Berry Transplanting Methods and Key Field Management Techniques
1. Transplanting can be done every year from leaf fall in autumn and winter until before bud break the following spring. Among these, March to April in spring is best. After digging up the seedlings, remove the excessively long fine roots, plant 1 seedling per hole, then return soil into the hole; when the hole is half filled, gently lift the seedling upward so its roots spread out, then fill the hole with soil, water thoroughly to settle the roots, and firm the soil. Then cover with another layer of loose soil 10 cm above the ground. 2. Field management (1) Intertillage and weeding, and turning and sunning the soil. Intertillage and weeding are generally carried out 3 times per year: the 1st in early May, the 2nd in early
