Tea plants are prone to banjhi (dormant buds) after autumn, so effective prevention and control are very important
Banjhi in tea plants refers to the phenomenon where tea buds are slow to grow, or bud break is delayed with a low sprouting rate and the new shoots produced are rather small. When tea plants are in the banjhi state, it is extremely favorable for flower bud differentiation, causing the tea plants to produce a large number of tea flowers from late October to mid-November, which consumes a great deal of nutrients, directly affects the growth of tea leaves the following year, and accelerates the aging of the plant. Therefore, preventing banjhi in tea plants is very important. To prevent banjhi in tea plants, the tea garden soil should be fully tilled 3-5cm deep in summer and autumn, so as to cut the soil capillaries and

Raccoon Dog Feed and Nutrition, Part One: The Importance of Water
Raccoon dog feed includes animal-based, plant-based and mineral-based feeds as well as synthetically produced products. How feed is supplied and what it is composed of has a great influence on the health, reproduction and fur quality of raccoon dogs. Artificially raised raccoon dogs have no choice whatsoever when it comes to feed, so keepers must rationally formulate and supply feed according to their living habits and their nutritional needs at different biological stages. If feed supply is insufficient during any one of these stages, or if the daily ration is not nutritionally complete or is improperly formulated, it will inevitably affect production results for the entire year. (1) Feed nutrients and their functions

The important role of protein in pigs and the amount to add
Protein is the foundation of all life and also the main component of the pig's body. According to research measurements, protein makes up 15% of the pig's body. It is the basic raw material for all tissues and cells of the pig's body, including muscles, bones, nerves, connective tissue, skin, and blood; it is the main component of skin, hair, meat, milk, bones, and hooves; and it is also an important raw material for the pig's body to form enzymes, hormones, pigments, antibodies, and other biologically active substances. When the diet is deficient in protein, sows are prone to abnormal estrous cycles, difficulty conceiving, fewer piglets born, easy miscarriage, and giving birth to weak

Important breakthrough made in hybrid japonica rice breeding
On the 18th, the reporter learned from the Shanghai Academy of Agricultural Sciences that agricultural scientists in Shanghai have made a breakthrough in hybrid japonica rice breeding in the Yangtze River Basin. Following the acquisition of the first hybrid late japonica rice restorer line in the Yangtze River Basin to obtain national plant variety protection rights, the first southern hybrid late japonica rice combination to pass national variety approval has also been bred. At present, a series of strongly heterotic combinations have become an important support for the "seed source" of hybrid japonica rice in the Yangtze River Basin. Researchers from the Crop Breeding Institute of the Shanghai Academy of Agricultural Sciences used intermediate materials between indica and japonica subspecies as "bridge parents"

What are the principles of watering bonsai? Mastering these few points is very important
1. The principle of watering: "Do not water when dry, water thoroughly when dry" - this is the principle of watering bonsai. It should be noted that when watering, avoid only wetting the surface soil and giving "half-way water," also called "waist-cut water," meaning the amount of water is insufficient and the pot soil is wet on top and dry below. "Half-way water," because the lower part of the pot soil is not moistened, is extremely unfavorable for tree roots to absorb water. In short, when the pot soil is dry, water enough until the pot soil is moist throughout from top to bottom. 2. Watering methods [1] Water according to season: In early spring, tree stumps begin to grow, and the amount of water needed gradually increases, but it should not be too much. When branches and leaves

The Important Role of Montmorillonite in Keeping Crystal Shrimp
Montmorillonite for crystal shrimp is specially used for keeping ornamental crystal shrimp, with a purity of 95-98%, pH 6.5-7.5, and can be placed directly into the tank for use. Montmorillonite for crystal shrimp can stabilize water quality, keep the water at a certain hardness (GH, 4-6) and carbonate hardness (KH, 1-2), and can absorb or inhibit the production of ammonia and organic amines. It is also academically recognized that montmorillonite can serve as the main component of the bacterial culture medium for cultivating nitrifying bacteria. 1 The Efficacy of Montmorillonite for Crystal Shrimp

Raccoon dog feed and nutrition: the importance of water
Raccoon dog feed includes animal-based, plant-based and mineral feeds as well as synthetically produced products. How feed is supplied and what it consists of has a major impact on the raccoon dog's health, reproduction and fur quality. Captive-bred raccoon dogs have no choice whatsoever when it comes to feed, so keepers must rationally formulate and supply feed based on the animal's living habits and its nutritional needs during different biological periods. If feed supply is insufficient during any one of these periods, or if the daily ration is nutritionally incomplete or improperly formulated, it will inevitably affect production results for the entire year.

Disinfection with chickens present is an important measure for green product production
Disinfection with chickens present is an effective measure for preventing and controlling avian influenza and Newcastle disease on large-scale chicken farms. It is especially necessary during periods with more spring winds, and for chicken houses housing flocks of different ages. The specific method of operation: choose an appropriate time. In winter, when temperatures are low, it is best to choose midday when the temperature is high, so the aerosol evaporates quickly, the chickens breathe it in quickly, absorb it quickly, and it takes effect quickly. In spring and summer, when the normal temperature is above 20°C, it is best to choose the afternoon or evening, when the temperature is constant and the aerosol evaporates slowly, so the floating disinfection time inside the house is long.

How do you choose among eight types of turtles? Mastering these selection tips is important
Turtle: The male should have a blackish carapace, a thick, solid tail base, and a long, deep concave plastron; the female should have a short, thick body and a short, thick tail. It is best to choose turtles aged 8 years or older, with the female weighing 350 grams; the male need only have reached the age of gonadal maturity, and the male-to-female ratio is 2:1 to 3:1. Golden coin turtle: When selecting, hold it in your hand and turn it over; its head will extend very long, be even in thickness, and its eyes will move flexibly and look lively. The skin is glossy, the temperament is docile, the gap between the upper and lower shells at the tail is large, and the cloacal opening is broad. Turtles aged 6 years or older are required, with the female weighing 1250 grams to 15
