How to store Gastrodia elata seeds for safe overwintering
The seeds can be stored in a pit dug inside a cellar. First dig a pit in the cellar; the size of the pit depends on the amount of seeds, and the pit depth is 45-50 cm. The vegetative propagation stems should be removed from the seeds, and they should be air-dried for 1-2 days before being put into the cellar. Sand with a moisture content of 20% should be chosen as the filling material. Sand that is too wet or too dry is harmful to the seeds. After the pit is dug, place a layer (3 cm thick) of sand with grains ranging in size from millet to sorghum at the bottom, lay out one layer of seeds, and arrange 4-5 layers of seeds in total, with the topmost layer covered by 5-6 cm of sand. Each layer of seeds must be laid out singly, with no contact between

Characteristics of the groundcover-type Dianthus variety and its planting and care methods
Groundcover Dianthus is a perennial herbaceous plant in the genus Dianthus of the family Caryophyllaceae, native to the United States and Japan. It was introduced to China in the early 1990s, and after more than ten years of cultivation, more dwarfed superior varieties have been bred. This variety blooms around May Day, with a flowering period of more than 50 days, and is both a flowering plant and a replacement variety for lawns. Groundcover Dianthus is a cold-hardy variety; in cultivation trials in Shandong, Shanxi, Hebei and other places, it can endure short-term low temperatures of minus 25°C to 30°C in the depths of winter. Under heavy snow cover, the leaves show no signs of freeze damage. Groundcover Dianthus is suit

Fox and raccoon dog mange mite disease must be carefully guarded against in autumn and winter, never be overlooked
In the current season, the breeding of fur animals is entering the fur growth period. In addition to meeting the various nutrients required for fur growth, special attention should be paid to the occurrence of external parasitic diseases. Zhaoyuan Farm has 100,000 foxes and raccoon dogs in stock and has rich experience in the prevention and treatment of lice and mange mite disease. The precautions are introduced as follows: Pay attention to observation. Skin diseases such as lice and mange mite disease cause great harm to fur animal breeding. They should attract sufficient attention from the vast number of breeding farms and breeders. Especially in the current winter fur growth season, inspecting and preventing mange mite disease is work that breeders must not neglect before pelting.

Why can flying snakes fly? Scientists uncover the mystery
You may find it hard to imagine how snakes, which have neither wings nor wing-membrane-like appendages, can "fly" like birds. Yet scientists have found that some snakes not only fly, but are masters of flight. Flying snakes generate power by shaking their ribs. Jack Socha of the University of Chicago in the United States has been studying snakes' flying ability for 8 years. Recently, Socha revealed in a professional journal the reason flying snakes are so good at flying. He said: "Although flying snakes lack wing-membrane-like appendages,

What are the easily overlooked problems in the process of selecting and retaining replacement gilts?
(1) The selection and retention procedure is unreasonable, and the selection process is simplified: In some pig farms, the selection and retention process for replacement gilts is very simple, with no fixed procedure. It is only after the breeding pigs finish testing that a simple evaluation is made and they are selected and retained. This can easily lead to an imbalance in the number of animals retained from each bloodline and a decline in the production performance of breeding pigs. Therefore, the selection and retention of replacement gilts must rely on a fixed procedure. Generally, the selection and retention of replacement gilts must go through three processes: primary selection, intermediate selection and final selection. Primary selection is when moving from the farrowing stage to the rearing stage, determining a candidate group 4 times the number to be retained for breeding; intermediate selection refers to the period from nursery to fattening

Key Techniques for Three-Membrane Covered Cultivation of Winter-Spring Potatoes
Three-membrane covered cultivation techniques for winter-spring potatoes (large arch shed, small arch shed, plastic film). Generally, sprouting is promoted and sowing is done in December, and harvest takes place at the end of March the following year. Each mu can yield about 3500-4000 kg of potatoes. It reaches the market one month earlier than early-spring plastic film covered potatoes, and the economic benefits are very significant. The cultivation techniques are as follows: 1. Site selection, shed construction specifications and planting specifications (1) Site selection and shed construction specifications. Choose plots with loose soil, sufficient water sources, and convenient drainage and irrigation to build sheds. Large arch sheds are generally 60 m long

Overwintering management of Panax notoginseng, Coptis chinensis, Morinda officinalis, and Ligusticum chuanxiong
Panax notoginseng: In winter, when the leaves turn yellow and wither, cut off the above-ground stems and leaves about 3 cm above the ground, collect the dead stems and leaves, remove weeds and diseased plant residues from inside and outside the garden, and burn them all outside the garden to clean the field. Then spray the bed surface with 1:1:200 Bordeaux mixture or 0.2-0.3 degrees Baume lime-sulfur mixture to fully disinfect the soil. If exposed roots are found, add appropriate soil covering. In addition, after cleaning the garden in November, apply 2000 kg of decomposed mixed fertilizer per mu at the plant roots to protect the buds through the winter safely. Before the seedlings emerge

Technical Service Information for Tea Plant Frost Resistance and Post-Disaster Recovery
I. Remedial measures for tea plants after a disaster: 1. Scientific pruning: Because tea gardens with different varieties, different altitudes, and different slope aspects have different degrees of frost damage to their tea plants, generally tea gardens with large-leaf varieties, high altitude, and north-facing slopes suffer more severe frost damage to the tea plants. Timely and reasonable pruning should be carried out according to the degree of frost damage. After the temperature rises and stabilizes, observe the frost damage to the tea plants. For lighter frost damage, use light pruning, that is, cut about 3 cm below the leaf surface. For more severe frost damage, carry out deep pruning, cutting off 1/2-1/3 of the plant. For particularly severe frost damage
