Four precautions for wheat seed dressing before sowing that you must remember
If the chemical seed dressing before wheat sowing is not operated correctly, it will not only fail to prevent diseases and pests, but may also lead to slow and uneven emergence of wheat, and even affect the normal growth of wheat seedlings. In general, the following 4 points should be noted when dressing wheat seeds with chemicals before sowing: determine the type of pesticide according to the local occurrence of pests and diseases. If the local pest infestation at the wheat seedling stage is very mild and the disease occurrence is severe, only a fungicide seed dressing is needed, and no insecticide is necessary; if pests and diseases occur together, both an insecticide seed dressing and a fungicide seed dressing should be used; if

What are the prevention and control methods for chicken embryos dying before pipping?
During incubation, it is very common for normally developed chicken embryos to be suffocated before pipping due to various factors such as an overly hard eggshell, limited space for the chick embryo's head to move, or its beak tip being too far from the eggshell. So, how can this phenomenon be prevented? 1. Turning the eggs. The first 10 days of incubation are the critical period for blastoderm positioning. To ensure the embryo's eye spot and head develop along the blunt-end shell edge of the hatching egg, so as to help the chick's beak tip pip the shell, the eggs should be turned frequently during this stage. During operation, the blunt end of the hatching egg should be kept facing up

How to distinguish true from false before introducing fragrant flower locust?
Nursery stock identification methods Currently the fake and inferior fragrant flower locust nursery stock sold on the market generally falls into the following four types: (1) Red flower black locust substituted for fragrant flower locust. The red flower black locust and the fragrant flower locust both have papilionaceous purplish-red corollas; the red flower black locust blooms once a year, bears pods, and is grafted using black locust as rootstock. The fragrant flower locust blooms twice a year, does not bear pods, and is propagated from root segments. (2) Aged root stock. Perennial fragrant flower locust root stock, due to aging, has an extremely low germination rate. According to trial plantings, fragrant flower locust root stock over two years old is not suitable for use as planting material, and even less should it be sold on the market

Detailed Explanation of Key Management Techniques Before and After Jujube Orchard Harvest
I. Care and Management Before Harvest 1. Preventing fruit drop. When jujube trees enter the ripening stage and up to the pre-harvest period, strong winds and heavy rain often cause fruit drop. Therefore, for jujube trees bearing many fruits, support poles should be set up for stabilization, and measures such as pulling and propping branches should be used to strengthen tree stability and reduce fruit drop caused by strong winds. 2. Adjusting unbalanced crowns. For jujube trees with unbalanced crowns where branches are lacking or there is space, inner-canopy branches and water sprouts can be pulled outward to fill the space, thereby adjusting the unbalanced crown and expanding the fruiting area. 3. Shallow hoeing to conserve soil moisture. Before harvest, for jujube orchard plots where soil moisture is particularly poor

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

What preparatory work should be done before sowing cotton?
I. Do a good job of pre-sowing preparation. Land preparation: for directly sown cotton fields, timely harrowing and smoothing should be done during the suitable moisture period to preserve soil moisture, so that the topsoil is loose and the subsoil is firm. 1. Deep plowing and land preparation: the plowing time for cotton fields can be divided into winter plowing and spring plowing, and winter plowing is better than spring plowing. Winter plowing should be deeper, generally 20-30 cm. Spring plowing should be appropriately shallower, generally 13-16 cm is suitable; after plowing, the land should be finely prepared, so that the topsoil is loose and the subsoil is firm, the soil is loose, and water is stored and moisture is preserved. 2. Apply sufficient base fertilizer: applying sufficient base fertilizer and building up soil fertility is the foundation for high cotton yields. The amount of base fertilizer applied should be determined according to yield, soil fertility and fertilizer

What are the pond-clearing methods? Remember these five before stocking fish fry
Before stocking fish fry, the aquaculture pond must be cleared to kill various predatory small wild trash fish, harmful aquatic animals and plants, parasite eggs, pathogenic bacteria, etc., creating a good environment for the growth of adult fish. The following five pond-clearing methods are introduced: 1. Clearing the pond with quicklime. When carrying out drainage pond clearing (that is, draining the pond water to a depth of 5-10 cm of remaining water before clearing), use 60-70 kg of quicklime per mu of pond; when clearing without draining, use 125-150 kg per mu of pond for every meter of water depth (200 ppm).

What are the precautions for spraying pesticides before fruit ripens
Pesticides that are prohibited include 1605, methyl 1605, fenitrothion, monocrotophos, methamidophos, trithion, omethoate, zinc phosphide, aluminum phosphide, carbofuran, asomate, chlordimeform, aldicarb, lindane and other pesticides. Dicofol also cannot be used on fruit trees because it contains high-residue DDT. Note the safety interval: the last spraying must be no less than 7 days before harvest for the following pesticides: 50% dichlorvos emulsifiable concentrate, 40% dimethoate emulsifiable concentrate, 50% carbendazim wettable powder, 50% iprodione wettable powder, 20% dinocap wettable

What are the precautions before and after a dog gives birth?
Pregnant dogs mostly give birth between the middle of the night and dawn. The time from delivering the first puppy to delivering the last one is sometimes quite long. Usually, after the first puppy is born, the second is born 15-20 minutes later, and the third 20 minutes after that... From the first puppy to the last one often takes half a day, and sometimes even longer. Therefore, the bedding cloth and sleeping straw should be replaced only after delivery is complete. The pregnant dog tosses and turns in her sleeping spot, arching her back with her abdomen enlarged. She also begins to strain, and this is labor pain. So-called labor pain means pain for a few minutes, then a pause for a few minutes.

What preparations should be made before first aid for a dog?
As your dog grows older, you may need to learn some emergency response measures for sudden accidents, such as it suddenly getting injured or falling ill. When you find that your dog has suddenly been injured at some unknown moment, do not panic. Remember that the purpose of any first aid measure is to stabilize the injured dog temporarily before the veterinarian arrives. Before starting, the owner must first determine whether the dog's life is in danger. If you find that the dog has stopped breathing, has no pulse or heartbeat, is bleeding continuously, or has been poisoned, you must immediately give the dog first aid. During the process, the dog may appear
