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

Analysis of the Causes of Tongue Root Rupture in Chickens and Methods of Prevention and Treatment
Many chicken farmers raise chickens with grain-based feed in economic forests and have achieved good economic benefits. However, because grain-based feed is severely deficient in vitamins, when the number of chickens raised is large and their range of activity is restricted, the flock, unable to get an adequate supply of green fodder, is often prone to tongue root rupture. Affected chickens show poor appetite, emaciation, and drooling; after opening the mouth, the tongue root is found to be ruptured, with no abnormalities seen in other organs. Affected chickens may account for about 15% of the flock. The treatment for this disease is: add poultry multivitamins to the chickens' daily ration and increase the supply of green fodder.

What to Do When Wheat Seedlings Turn Yellow? Common Causes and Control Methods
When wheat grows into the winter and spring seasons, the seedlings often turn yellow or even die, and applying fertilizer alone cannot make them turn green again. There are several types of yellowing in wheat seedlings, and if remedial measures are not taken in time, they can cause serious reductions in wheat yield. Yellowing from pests: yellowing of leaves caused by wheat aphids and wheat mites sucking leaf sap, occurring mainly around the overwintering period. Per 667 sq m, use 65-75 ml of 40% omethoate emulsifiable concentrate mixed with 50 kg of water for spray control. Yellowing from disease: wheat sheath blight damages

Analysis of the Causes of Dead Orchid Seedlings in Chinese Cymbidiums and Prevention Methods
Orchid seedlings develop scorched tips, yellow leaves, yellow leaf sheaths, rotten hearts, rotten roots, and rotten pseudobulbs, and eventually the entire plant dies, causing huge economic losses to investors in fine Chinese cymbidium varieties. Orchid enthusiasts have different opinions, and only when cultivation becomes difficult does one truly understand orchids. Investigation and analysis show the main causes: First, excessive fertilizer. Chinese cymbidium cultivation media should be lean rather than rich; when mixing, do not worry that fertility is insufficient and add too much fertilizer-heavy medium. If the growing soil is found to be too rich, it should be replaced promptly or technically treated. During Chinese cymbidium management, if the plants can grow normally relying on the medium, there is no need for extra

How can spent mushroom substrate be reused? Here are several practical methods
In rural areas, some mushroom growers lack awareness of environmental protection. After the growing season ends, they move the spent substrate out of the mushroom house and let it rot in the open, which both pollutes the environment and wastes a usable resource, which is truly a pity. How can spent mushroom substrate be turned from waste into treasure? Here are 4 methods for reusing spent mushroom substrate that you might want to try. 1. As a substrate for cultivating shaggy ink cap mushrooms (Coprinus comatus). Spent substrate from mushroom cultivation, as long as the mycelium grew well and the substrate was not contaminated by competing microorganisms, can be sun-dried and crushed, then added at 30% to new substrate for cultivating shaggy ink cap mushrooms, and its economic benefit

Dry Pinellia Greenhouse Planting Methods and Technical Key Points
Dry Pinellia, also known as three-leaf pinellia, three-step jump, and hemp jade fruit, is a commonly used Chinese medicinal herb, with wild distribution throughout both northern and southern China. In recent years, due to people's reclamation and utilization of barren hillsides and the extensive use of herbicides in farmland, its ecological environment has been damaged, resources have decreased year by year, and prices have continued to rise. According to surveys, dry Pinellia products are currently scarce in seventeen specialized medicinal herb markets nationwide, supply has fallen short of demand, and the market price has remained firm at 36-42 yuan/kg. Therefore, the market prospects for artificially cultivating dry Pinellia are very broad. In recent years, we

Causes and Control Methods of Peach Gummosis
Peach gummosis is a disease commonly found on peach trees today, and it occurs severely. Especially in poorly managed orchards and those with weakened tree vigor, the incidence of affected trees can reach over 90%. This disease severely weakens tree vigor, affects yield and quality, and in severe cases leads to branch and tree death, threatening the production and development of peach trees. It is also the most troublesome disease for fruit growers. I. Causes. There are two causes of peach gummosis: one is non-infectious pathogens, such as gummosis caused by wounds from mechanical injury, insect and disease damage, frost injury, freezing injury, etc., or gummosis caused by physiological disorders of the tree body due to extensive management, excessive pruning, excessive fruiting, improper fertilization, heavy clay soil, etc. The other is infectious pathogens caused by fungi, with the sexual stage belonging to Ascomycota and the asexual stage belonging to Deuteromycota.
