How is scorpion venom produced? A detailed explanation of its formation process
The medicinal value of scorpions depends mainly on scorpion venom. The poisoning symptoms caused when people are stung by scorpions are also the effect of scorpion venom. The toxicity of scorpion toxin is similar to that of snake toxin and is extremely severe. Scorpion venom acts on frogs, guinea pigs, rabbits and other animals, and can produce poisoning in all of them. Its median lethal dose (LD50) for mice is 1.6 milligrams per kilogram of body weight (male mice) and 1.4 milligrams (female mice). However, its toxicity is destroyed when heated to 100°C for 30 minutes. The pharmacological functions of scorpions depend mainly on scorpion venom. Scorpion venom

A Complete Guide to Management Key Points During the Cotton Yield Formation Period
This year, the light and heat conditions in the early stage were relatively favorable for cotton growth, but the recent low temperature, scant sunlight, and rainy weather have been extremely unfavorable to cotton growth, and boll shedding has increased noticeably. We are currently in the critical period for cotton yield formation. To secure a high cotton yield, the following management measures should be strengthened: 1. Supplemental application of top-covering fertilizer and foliar spraying. For cotton fields with many set bolls and fields showing premature senescence, apply 5-7.5 kg of urea per 667 sq m, or combine this with pest control for foliar spraying. 2. Reasonable pruning and chemical regulation. Due to the recent rain

Detailed Explanation of Key Technical Points for Inducing Bud Formation and Shelf Fruiting of Shiitake Mushrooms
After the substrate bags change color, they enter the fruiting stage. The key management points during the bud induction period are: manually increase the temperature difference and the wet-dry difference, keep the temperature at 15-20°C and the humidity at 85%-90%, combine with ventilation, and apply temperature difference stimulation; after 3-5 days, mushroom buds will appear in large numbers. In winter, bud induction focuses mainly on heat preservation. The methods are: (1) Induce buds on indoor shelves: arrange the substrate bags neatly on the shelves with 2 cm between bags, place 1-2 stoves in the room, keep the temperature at 15-20°C, ventilate 3 times a day for about 1 hour each time, remove coal

Methods and Key Technical Points for Controlling Peach Shoot Growth and Promoting Flower Formation
Many peach growers have called to ask how to stop peach shoot growth and form more flower buds. The main factor affecting flower bud differentiation is the conflict between reproductive growth and vegetative growth. When vegetative growth is too vigorous, it seriously affects reproductive growth, that is, flower bud differentiation. Therefore, during the flower bud differentiation period (late May to before leaf fall), attention must be paid to the balance between the two in order to ensure normal flower bud differentiation. 1. From late May to June, pinch off the shoot tips at the 10-12 leaf position on autumn shoots to promote flower bud differentiation and branching, or spray Shoot Control Ling (Kongshao Ling).
