Seven methods of applying nutrient solutions to increase oyster mushroom yields
1. Sucrose and calcium carbonate phosphate mixed solution: sucrose 1%, calcium carbonate 1%, potassium dihydrogen phosphate 0.1%. Use when the mycelium has covered the mushroom bed and before fruiting bodies appear. 2. Urea and citric acid mixed solution: urea 0.5%, citric acid 0.1%, adjust pH to 7 with sodium hydroxide. Use after the first flush of mushrooms is harvested. Using it after the second flush is not effective and instead hinders oyster mushroom growth. 3. Sugar, urea and citric acid mixed solution: sucrose, citric acid and urea 1% each, adjust pH to 7. Same

Control Methods and Technical Key Points for Physiological Diseases of Oyster Mushrooms
Oyster mushrooms have the characteristics of wide adaptability, strong stress resistance, a wide range of cultivation material sources, simple cultivation techniques, and high economic benefits. In recent years, oyster mushroom production has developed rapidly in our county, but in production, various non-infectious physiological diseases often occur due to poor management, causing yield reductions and directly affecting the economic benefits of oyster mushroom production. Based on many years of production practice experience, we have summarized the symptoms and control techniques of several main physiological diseases that commonly occur in oyster mushroom production. 1. Excessive mycelial growth In oyster mushroom production, excessive mycelial growth often causes the mycelium to become dense

A Detailed Guide to the Prevention and Control of Pests and Diseases on Japanese Honeysuckle (Lonicera japonica)
Anthracnose occurs frequently in summer and can be controlled by drenching with a 500-1000 times dilution of wettable Dexon powder. For rust, spray a 200-250 times dilution of the technical-grade dithianon sodium (you may add 50-100 g of washing powder to 50 kg of the spray solution as a sticker). Insect pests include aphids, longhorn beetles and others; aphids can be sprayed with a 4000 times dilution of 10% imidacloprid, while longhorn beetles can be sprayed with a 500 times dilution of duomeike (methomyl). Note, however, that toxic pesticides must never be used on Japanese honeysuckle during the bud stage.

Pinellia ternata pest and disease control methods and key technical points
(1) Root rot: This disease is prone to occur in hot seasons when water accumulates in the field. After onset, the underground tubers rot, and the aboveground parts then collapse and die. Control methods mainly focus on drainage, removing diseased plants and treating the diseased holes with 5% lime water or pouring it on the roots; alternatively, soak seeds in 0.5%-2% lime water for 12-30 hours at sowing time. (2) Viral disease: Manifested as leaf curling and mosaic, mostly occurring in spring and summer. After onset, diseased plants should be pulled up and burned, and the area disinfected with lime. (3) Red hawk moth: With

What are the pest and disease control methods for Codonopsis pilosula?
Codonopsis pilosula is a commonly used traditional Chinese medicine. It is widely cultivated in northern China, and its roots are used medicinally. It has functions such as tonifying qi and nourishing blood, harmonizing the spleen and stomach, and promoting fluid production and clearing the lungs. It is mainly used to treat various qi deficiency conditions such as shortness of breath and weakness, thirst due to fluid damage, weakness of the spleen and stomach, loss of appetite, loose and watery stools, cough and asthma due to lung deficiency, weakness after febrile disease, and prolapse of the anus due to qi deficiency. It has a very wide range of uses. The pest and disease control methods are introduced as follows: 1. Root rot often begins to occur during the high-temperature and high-humidity period from May to June in summer. It mainly occurs in Codonopsis pilosula plants that have been growing for more than 2 years. In the early stage of the disease, the lateral roots near the ground

Detailed Explanation of Methods and Techniques for Angelica Pest and Disease Control
Root rot: Soak seedlings in 1:1:150 Bordeaux mixture, disinfect and insecticide-treat the soil: burn and fumigate the soil more in seedling beds. Brown spot: Pay attention to field sanitation, promptly remove diseased leaves, and in the middle and late stages spray 1:1:150 Bordeaux mixture once every 7 days. Pests: Mainly green peach aphid, commonly known as "oil worm." It multiplies in large numbers during May, densely gathering on the undersides of leaves of new shoots and tender leaves of angelica to suck sap, causing heart leaves and tender leaves to thicken, curl into a fist-like shape, and the plant to become stunted. Control methods: Clear weeds around the field to reduce opportunities for aphid migration; when aphids occur

Methods for the prevention and control of Angelica sinensis pests and diseases and key technical points
(1) For stem nematode disease (má kǒu bìng), the peak periods of occurrence are in mid-April, mid-June, early September and early November after transplanting; it damages the roots, and an abundance of soil-dwelling pests favours its occurrence. Control methods: ① Per mu, use 3 kg of 3911 granules mixed evenly with 15 kg of fine soil, or 0.5 kg of 20% methyl isofenphos emulsifiable concentrate mixed with 2.5 kg of water and sprayed onto 15 kg of soil and mixed evenly, then broadcast and turn into the soil; ② Regularly drench the roots with a broad-spectrum, long-lasting insecticide; per mu use 250 g of 40% carbendazim suspension concentrate or 600 g of thiophanate-methyl plus

Licorice Pest and Disease Control Methods and Key Technical Points
(1) Rust disease: After infection by fungi, yellow-brown blister-like lesions appear on the underside of leaves; when they rupture, brown powder is released, which consists of the pathogen's telial and urediniospore stacks; in August and September, dark brown telial stacks form. Control methods: Gather diseased plants and burn them. In the early stage, spray 0.3-0.4 degrees Baumé lime sulfur mixture or 97% dithianon sodium 400-fold solution. (2) Brown spot disease: After infection by fungi, round and irregular lesions appear on leaves, with a grayish-brown center and brown edges; gray-black mold-like growth occurs on both the front and back of the lesions. Control

What are the common pests and diseases of licorice (Glycyrrhiza) and their control methods?
(1) Rust: in the early stage of the disease, spray with 25% triadimefon wettable powder at 1000 times dilution or 97% dinocap at 300 times dilution for control, once every 7-10 days, for a total of 2-3 sprays. (2) Brown spot: spray once with 1:1 Bordeaux mixture before the disease occurs; in the early stage of the disease, choose 70% thiophanate-methyl wettable powder at 2000 times dilution or 75% chlorothalonil at 500 times dilution for spray control, once every 7-10 days, for a total of 2 sprays. (3) Aphids: during the occurrence period, spray-kill with 40% dimethoate emulsifiable concentrate at 1500 times dilution.
