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

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"

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

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

How important is the rearing environment in chicken farming?
With the deepening of agricultural industrial structure adjustment and the internal structural adjustment of the livestock industry, the construction of breeding communities has developed rapidly, but because most poultry farmers do not have sufficient understanding of the rearing environment for chickens, the rearing efficiency of chickens is relatively poor. Several key issues in broiler rearing are briefly discussed below. 1 The harm of poor ventilation. Because broilers grow quickly, have vigorous metabolism, and are raised at high density, as the chickens continue to grow, the amount of fresh air needed increases more and more, more and more feces are excreted, and more and more harmful gases are produced.

4 Important Life Habits You Must Know for Raccoon Dog Farming
The raccoon dog's life habits have the following four characteristics. (1) Gregariousness: wild raccoon dogs usually live in pairs in dens, with 1 male and 1 female per den, though there are also cases of 1 male with multiple females or 1 female with multiple males. The parents and pups of neighboring dens usually play and frolic together, and mother raccoon dogs sometimes even nurse each other's young indiscriminately. Under domestic conditions, this characteristic can be used to group weaned pups into groups of 10~20 and raise them together in pens. (2) Nocturnal: this characteristic is very obvious in wild raccoon dogs. They sleep in their dens during the day and come out around dusk and dawn to move about and
