What are the digestive physiological characteristics of donkeys? Read this article to understand
Digestive physiological characteristics of donkeys: Donkeys have hard, well-developed teeth and flexible upper and lower lips, suitable for chewing coarse and hard feed. Donkeys have well-developed salivary glands; every 1 kg of forage can be softened and digested by 4 times its amount in saliva. The donkey's stomach is small, only equivalent to one-fifteenth that of a cow of the same size. The cardiac sphincter of the donkey's stomach is well-developed, while the vomiting nerve is underdeveloped, so it is not easy to feed feed that ferments and produces gas, to avoid gastric dilation. Chyme stays in the stomach for a short time; when the chyme in the donkey's stomach reaches two-thirds, as feeding continues, the stomach contents are continuously

High-yield cultivation method of cutting oyster mushroom blocks into pieces, standing them upright and covering with soil
Mushroom farmers in Dongkan Town, Binhai County, Jiangsu Province, through years of oyster mushroom cultivation practice, worked out the six-character high-yield formula for oyster mushrooms of "cutting into blocks, standing upright, covering with soil", which increased the oyster mushroom yield per mu by more than 2000 jin compared with the past, with an increase rate of about 30%, and at the same time, production costs dropped greatly. Their high-yield experience mainly consists of three steps: "cutting into blocks, standing upright, covering with soil". The so-called "cutting into blocks" means that at the end of harvesting the second flush of mushrooms in furrow-bed cultivation, the dead mushrooms, stipes and the like remaining on the bed surface are cleaned up, and a sharp knife is used to cut the cultivation substrate into multiple pieces of about 50 cm

How to control the jujube bud weevil? Understanding its life habits is key
The jujube bud weevil belongs to the order Coleoptera, family Curculionidae. It occurs in Henan, Hebei, Shanxi, Liaoning and other famous jujube-producing areas, mainly harming jujube, apple, pear and other fruit trees. The jujube bud weevil emerges from the soil in early spring and first damages the young buds of jujube trees. It is the earliest pest to appear on jujube trees. When the population density is high, it can eat all the jujube leaves, causing a second flush of buds and resulting in reduced yield or total crop failure. The adult is dark gray or earth-yellow, with a black head, two curved elytra that are 2 times as long as wide, and a silvery-gray ventral surface. The eggs are milky white, turning brown later, oblong,

How to control the Japanese wax scale on goldenrain tree? First understand its occurrence pattern
The Japanese wax scale (Ceroplastes japonicus Gr.) belongs to the order Homoptera, family Coccidae. Also known as the Japanese wax scale and the jujube armored wax scale, commonly called the jujube louse. When it breaks out over large areas on goldenrain trees, in severe cases the entire tree's branches and leaves are covered with the insects, and female insects attached to the twigs look like snow from a distance. The nymphs suck sap on the leaves, and their excrement covers the whole tree, weakening the tree's vigor and seriously affecting the landscaping appearance. Through two years of investigation and study, the occurrence pattern of this pest was clarified, and a satisfactory control method was found. This pest

For high garlic yields, understanding its fertilizer requirements is key
Garlic is a bulb crop with a high fertilizer demand that is also relatively tolerant of heavy fertilization. It is best grown in sandy loam soil rich in organic matter, with a loose and fertile topsoil, complete nutrition, good water and fertilizer retention, and good aeration. According to research: for every 1000 kg of fresh garlic produced, 4.5-5 kg of nitrogen, 1.1-1.3 kg of phosphorus, and 4.1-4.7 kg of potassium are required, in a ratio of 3:1:3. Therefore, on the basis of fully understanding garlic's growth characteristics and fertilizer requirements, applying scientific fertilization is the key to achieving high-quality, high-yield garlic. According to garlic's growth characteristics and

Detailed Explanation of Key Points for Standardized Garlic Cultivation Techniques
1. Garlic field site selection. Choose second-category fields with loose, fertile soil, abundant water, convenient drainage and irrigation, and suitable for garlic-rice rotation for garlic cultivation. 2. Careful land preparation. After the previous crop is harvested, plow while there is still moisture in the soil, or use a rotary tiller to prepare the land when the field is half-dry, making beds 2 m wide, with bed width 1.5-1.8 m, complete with three ditches, ditch depth 0.2 m, ditch width 0.3 m, and carefully prepare the land to achieve level beds, fine soil, and both drainage and irrigation capability. 3. Apply sufficient base fertilizer. Apply 50 loads of farmyard manure per mu, 75 kg of potassium sulfate compound fertilizer, and 50 kg of ammonium bicarbonate, spread evenly before land preparation

Detailed Explanation of Key Techniques for Achieving a Full Stand of Cotton from a Single Sowing
The technique of achieving a full stand of cotton from a single sowing has been a technical issue of concern to our cotton farmers and technicians for many years. It involves many factors - soil temperature, soil moisture, sowing methods, seed quality and treatment - all of which are key to achieving a full stand from a single sowing. Therefore, we discuss with cotton farmers how to achieve a full stand of cotton from a single sowing with strong seedlings and early development. I. Pre-sowing preparation. Preparation before sowing is the prerequisite and foundation for a full stand from a single sowing. As the saying goes, "Troops and horses move only after provisions are ready" and "Ten months of pregnancy, one day of delivery" - both illustrate the importance of preparation. Pre-sowing moisture building: by
