How to prevent and control garlic leaf blight? These methods you need to master
Control measures for garlic leaf blight: 1) Promptly remove damaged leaves and flower stalks; 2) Strengthen field management, plant at a reasonable density, drain promptly after rain, and improve the host's disease resistance; 3) Starting at the early stage of the disease, spray 75% chlorothalonil wettable powder at 600 times dilution, or 50% iprodione wettable powder at 1500 times dilution, 64% oxadixyl-mancozeb wettable powder at 500 times dilution, 50% copper sulfate-ammonium salt wettable powder at 500 times dilution, 60% fosetyl-aluminum wettable powder at 500 times dilution, 14% copper ammonia complex aqueous solution at 300 times dilution, 1:1

Detailed Guide to Garlic Storage Techniques: Master the Correct Preservation Methods
Optimal storage temperature: 0°C. Relative humidity: above 95% RH. Garlic shows no chilling injury; as long as it is kept above freezing point (close to 0°C), the lower the temperature, the longer the storage life. Like other leafy vegetables, garlic also requires relatively high humidity to avoid dehydration and wilting, which cause losses. Although topped garlic has a smaller leaf area and loses less weight than whole-stem garlic, storage above 0°C often leads to rot from wound infection, and the leaves tend to yellow, shortening the storage period. Therefore, topped garlic must be sold within a short time and cannot be stored long-term.

How to manage garlic before winter? These technical points must be mastered
1. Topdressing. Garlic has a high fertilizer demand. In addition to applying sufficient base fertilizer, at the 3-leaf stage, fertilizer must be applied once, with 2000-2500 kg of diluted manure water per mu, or 20-25 kg of ammonium bicarbonate mixed with 2000-2500 kg of water for drenching. When applying chemical fertilizer, it must not directly touch the garlic leaves to avoid burning. 2. Intertillage and hilling. Combined with topdressing, carry out intertillage and hilling once, banking fine soil from between the rows up to the base of the garlic seedlings, which can both prevent fertilizer volatilization and preserve soil moisture and prevent freezing. 3. Drought prevention. Garlic is afraid of drought, and drought will affect

Stocking fish fingerlings in early spring requires care; mastering the method is key
Fingerling quality For fingerlings of the same species and age, the specifications should be uniform, with little difference in body length and body weight, thick back muscle, bright color, intact scales and fin rays, normal activity, and strong upstream-swimming ability. After being taken out of the water and placed in a basin, the gill cover should not open, the tail should not bend, and the fish should keep jumping, with no wounds or parasites on the body surface. Fingerling disinfection Some farmers do not disinfect fingerlings at all when stocking them, resulting in a high disease rate, and drug treatment is not ideal. In fact, as long as fingerling disinfection is done well, it often achieves twice the result with half the effort in preventing fish diseases. Fingerlings

How can the efficacy of fishery drugs be improved? Master these five methods
Improve the binder The binder must be highly sticky, otherwise the drug will easily disperse and be lost in the water. Standard wheat flour is a relatively good binder material. For swallowing fish, it is best to make pelleted medicated bait or ball-shaped medicated bait for feeding. Add a feeding attractant Fish have a keen sense of smell; even if 1 gram of alanine is dissolved in 1 million liters of water, fish can still detect it. For example, if strongly aromatic Chinese herbal medicines such as star anise and Angelica dahurica are ground into fine powder to make a feeding attractant, and mixed into fishery drugs at a ratio of 10%-20%, or added to roasted soybean powder, wheat flour, etc., all have obvious feeding-attractant effects

How to safely overwinter shiitake mushrooms through summer? These management points must be mastered
The quality of summer management for shiitake mushrooms directly affects yield and profitability. Doing a good job of summer management is a key step in shiitake mushroom production, and two methods can be used: indoor and outdoor. I. Indoor spawn running for summer survival (1) Minimize the number of shiitake bags indoors and the number of bag layers. Stack two bags in a cross pattern, with no more than 5 layers at most, and keep the spacing between stacks at more than 20 cm to facilitate ventilation and heat dissipation. (2) Build a shade canopy outside the window so that sunlight does not shine directly onto the window or indoors. (3) In hot weather, close doors and windows at 7 a.m. to prevent outside hot air from entering indoors, and in the evening

How to master the dehydration step in shiitake mushroom processing
Dehydrated shiitake mushrooms with good commercial value have bright yellow gills, a plump shape, uniform size and a rich aroma. To process good shiitake mushrooms, mastering the "dehydration step" is crucial. 1. Timely harvesting: this is the basis for ensuring the finished mushrooms have bright color. The main reason shiitake mushrooms become discolored during drying is that the mushroom bodies are injured before drying. To overcome this shortcoming and enhance the mushroom bodies' resistance to external pressure, timely harvesting is very important. They should be harvested when the partial veil has fully split and the cap has curled upward like a gong. Do not spray water in the 4 hours before harvest; harvest using the "twist-harvest method",

How to manage azaleas during the bud stage? Master these key points
Azaleas prefer a cool and humid climate, and require acidic soil rich in humus, loose, moist, with a pH value between 5.5-5.6. They have certain requirements for light, are not tolerant of exposure to the sun, and are best cared for under semi-shade conditions. The bud stage refers to the period from the beginning of bud formation to the opening of most flowers, generally 90-120 days. The length of this period is greatly related to humidity and care. To make the flowers bloom well and for a long time, attention must be paid to bud stage management. The key points are as follows: 1. Light

How to care for azaleas during the bud stage? Master these key points
Azalea bud-stage care refers to the growth stage after buds appear, when most buds begin to enlarge, up to just before flowering, generally about 90-120 days. However, the length of this growth period is closely related to temperature: the lower the temperature, the longer the period, and vice versa. If you want the azalea to bloom on schedule, bud care is especially important. The main techniques of bud care are briefly introduced below: 1. Suitable temperature. Azaleas are especially sensitive to temperature during the bud-care period, so it is most suitable to place the pot in a moderate-temperature greenhouse for care.

How to raise blue foxes? Master these four breeding techniques
This year, in Pulandian City, Liaoning Province, 10 specialized blue fox farming households averaged more than 8 cubs per litter, more than 40% higher than the local female foxes' litter size. In the survey, it was learned that skilled fox farmer Cai Yu achieved high results in mating rate, pregnancy rate, whelping rate, survival rate and economic benefit, with a cumulative average of 10.4 cubs per litter over 3 years. Because the blue foxes he raised were pure in breed and excellent in quality, his breeding foxes and fur sold well. His main experience consists of 4 techniques: introducing fine breeds. The breeding male and female foxes raised by Cai Yu were all purchased from the fur animal experimental breeding base of the Special Products Research Institute of the Chinese Academy of Agricultural Sciences in Zuojia, Jilin
