After spring tea is picked, the tea plant branches and stems need even more protection
Whether or not tea plants are managed after the spring tea harvest makes a big difference, because after the spring tea harvest the plant body has already consumed a large amount of nutrients. If management cannot keep up at this time, it will not only affect the yield and quality of summer and autumn tea, but also affect the yield and quality of next year's spring tea. Based on our farm's practical experience, the following key points should be carried out after the spring tea harvest: 1. Reasonable topdressing. According to measurements, producing every 50 kg of dry tea requires absorbing about 2.5-3 kg of nitrogen, 0.9-1.2 kg of phosphorus, and 1.1-1.5 kg of potassium from the soil. Between the tea plants, 30 cm

How to select superior mushroom spawn? Growers need to master these methods
Spawn is the foundation and guarantee for achieving a high yield of edible mushrooms, and the quality of the spawn directly affects the economic benefits of edible mushroom production. When purchasing superior edible mushroom spawn, pay attention to the following aspects. 1. Identify the market and select varieties. Edible mushroom prices differ across regions, seasons, and years. Mushroom growers cannot stick to old rules when selecting varieties; they must adapt to circumstances and start from the following aspects. 1. Choose varieties with good prices, such as "2796" among button mushrooms, oyster mushroom p54 "New Century", small oyster mushrooms, straw mushroom v23, v35, and other varieties. They are usually in short supply and command good prices, can win through price, and are especially suitable for development in suburban areas.

How to Select Young Pigeons? These Selection Tips You Need to Know
The rise and fall of a pigeon loft, from a breeding perspective, depends to a great extent on the selection of young pigeons. The young pigeons produced should be selected. If they are all kept regardless of quality, it not only wastes energy and resources, but also leads to a decline in the overall racing performance of the loft. Conversely, carefully selecting high-quality young pigeons is very beneficial for both breeding and racing. Therefore, pigeon fanciers must pay attention to the selection of young pigeons. How to select young pigeons? 1. Bloodline is the foundation. Based on racing practice, select and keep young pigeons with good bloodlines and outstanding performance from the loft as breeding pigeons for the next generation. For crossbred pigeons, young pigeons with the most outstanding hereditary bloodlines can be selected and kept for competition preparation. In this way, you must clearly identify your own @#@247@#@, which bloodline should serve as the main bloodline, and which ones as the pairing bloodlines. Keep the main bloodline for breeding, and use the crossbred bloodline for competition. 2. When selecting young pigeons, look at body type. For a racing pigeon to win in fierce competition, facing thousands of strong pigeons like a forest, even in a contest decided by a few thousandths of a second, besides having a superior bloodline, appearance, and eyes, the remaining condition is physical fitness. Physical fitness includes body type, and pigeons with a streamlined body type should be selected. Understood from the principles of aerodynamics, streamlined racing pigeons have low flight resistance, good balance, longer sustained flight time, and less physical exertion. Therefore, when selecting any breed, streamlined body type pigeons are the first choice. In terms of overall form: length, width, and thickness, that is, body length, back width, and chest thickness. Judging from the data of winning racing pigeons, most winners in short- and medium-distance races are short and stocky, or short and compact. Such racing pigeons often have strong explosive power but short sustained flight time. This is determined by their body type characteristics. In other words, the body type characteristics of short- and medium-distance pigeon breeds and long-distance and ultra-long-distance pigeon breeds are different. Therefore, when selecting young pigeons, the body type of the young pigeons should be chosen in accordance with the competition category. 3. Selection of young pigeons' eyes. Because they are young pigeons, everyone's method of judging pigeons differs, and some people still cannot see much of anything. But practice tells us that bloodline pigeons with good iris texture, pupil, eye sign, and inner line are beneficial for both breeding and racing. 4. The skeleton of young pigeons is also very important. "Judging bone when releasing" was Zhang Wanzhong's profound theory 300 years ago. Unfortunately, it has still not been taken seriously by all pigeon fanciers to this day. The skeleton is the foundation that constitutes a racing pigeon. The skeleton is the support for all the moving parts of the racing pigeon and for the muscles that produce movement. Only a strong, supple, and solid skeletal structure can provide a suitable support for different muscle groups. When a young pigeon is held in the hand, it should feel hard-supported and solid. The keel should be long, thick, and curved. One end of the pubic bone should tilt slightly upward; the pubic bones should be short, thick, and solid, and close tightly. The humerus should be thick, strong, and hard, and when flapping it is powerful, which can increase the frequency of flapping. 5. Muscles. The large pectoral muscles appear full and strong, giving a sense of firmness and composure. After training and competition, a racing pigeon's fat has all disappeared, and its large pectoral muscles change from soft to elastic. When the pigeon is held in the hand and its wings are spread, the two wings produce a soft and elastic feeling. 6. Feathers. The feathers should have good downy softness, be smooth, glossy in color, with feather barbs as fine as silk, closely arranged into flat and thin elastic feathers, clinging tightly to the whole body, giving a feeling of slipping out of the hand when held. 7. Overall appearance. Young pigeons should have a strong physique and an intelligent, calm, and confident demeanor. They should give a sense of balance. The two legs should not be too long or too straight, nor should they appear too short. Male pigeons should have a natural and poised masculine appearance; female pigeons should have a dignified and elegant feminine appearance. They should be "still as a maiden, moving as a dragon." They should be affectionate toward their owner and highly alert toward strangers. Regarding the selection and views on young pigeons, this is merely my humble opinion. At present, in the pigeon-keeping field, there are no professional schools, no fixed teachers, and no fixed models. One must rely on oneself to learn and explore, and communicate more with fellow pigeon fanciers. Therefore, one should not fear failure or setbacks, nor should one become complacent and stagnate after achieving results. One should humbly learn from others' strengths, understand the merits of other pigeon lines, and introduce good bloodline pigeons at the appropriate time, which will add new vitality to one's own loft and may also produce unexpectedly good results.

What role do carbohydrates play for pigs? What pig farmers need to know
Carbohydrates are composed of three elements: carbon, hydrogen and oxygen. They are the main component of plants, accounting for about 70%-80% of all nutrients in plants, and are the main energy source in pig feed. After carbohydrates enter the pig's body, they are transformed into energy through a series of changes, providing heat energy for the pig's various life activities. The carbohydrates remaining after meeting daily energy consumption can be converted into fat in the pig's body and stored as an energy reserve, to be used when hungry. The pig's fat and leaf fat are this reserve of surplus energy. Pigs have a strong ability to convert carbohydrates eaten into fat, and when a large amount of carbohydrates is eaten, body fat increases quickly as well, so feeding pigs with feed rich in carbohydrates (such as corn, rice, sweet potato, potato) makes it easy to convert into body fat. When raising lean-meat pigs, carbohydrates should be supplied reasonably, especially in the late fattening stage, when the feeding amount of such feed should be appropriately reduced to prevent the pig from becoming too fat.

Three things to avoid when feeding vegetables to rabbits; rabbit keepers need to know this in advance
First, avoid using vegetables that have been piled up and turned yellow. Feeding rabbits with vegetables that have been piled up and turned yellow will cause nitrite poisoning in rabbits, and in severe cases can lead to death. Therefore, when feeding rabbits with vegetables, always make sure they are fresh, and do not feed too much at a time; it is best to feed them together with other feed. Second, avoid cruciferous vegetables. Cruciferous vegetables contain sinigrin, which can produce some toxins that promote thyroid enlargement and severely damage the rabbit's liver and kidneys. Third, avoid vegetables damaged by pests. Feeding rabbits with vegetables infested by aphids, cabbage caterpillars, and the like

Chestnut gall wasps need targeted control this year, and chestnut growers should pay attention
The chestnut gall wasp, also known as the chestnut tumor wasp, is a major insect pest damaging chestnut trees. It occurs almost every year in chestnut-producing areas in China, but this year the outbreak is especially severe. Large trees, especially old unpruned trees, have reached a 100% damage rate. Controlling the chestnut gall wasp brooks no delay. The chestnut gall wasp has one generation per year and overwinters as first-instar larvae inside infested chestnut buds. In the Yanshan mountainous area, overwintering larvae begin to move and feed during the bud-break period in mid-April and grow rapidly. In early May, during the shoot-sprouting and leaf-unfolding period, galls begin to form. The galls are mostly at the tips of new shoots or

Do rabbit droppings need to be cleaned up every day? A detailed explanation of rabbit dropping cleaning frequency
Teacher Xu Shangjin, a rabbit-raising expert from Heilongjiang, China, said he discovered that rabbit droppings have a thin film on the outside, and about ten minutes after the droppings fall onto the dropping board, this thin film dries up. If you do not break it, the droppings do not smell or give off odor! If you insist on a system of cleaning the droppings once every day, it will inevitably cause the dropping pellets to break and release foul and unusual odors. In addition, it also shows that cleaning droppings inside the rabbit house every day will inevitably affect the rabbits' rest. If rabbits do not rest well, they will not grow well. Therefore, cleaning droppings every day is not recommended, and at the same time it is strictly forbidden to
