Noteworthy specific germplasm of wild apricot (Prunus sibirica) in Chaoyang, Liaoning
Abstract: We surveyed apricot germplasm resources in Chaoyang City, Liaoning Province, and identified 11 specific germplasms, including 3 kernel-use germplasms, 4 landscaping germplasms, and 4 germplasms pending further identification. These new germplasms not only enrich the apricot germplasm resources of Liaoning Province, but also lay a material foundation for breeding new cultivars. Keywords: apricot germplasm, kernel use, landscaping. Chaoyang City, Liaoning Province is one of the main apricot production areas in China, with a long history of apricot cultivation. In the past, local wild apricots were mostly propagated by seed, and the genetic differences of wild apricot at the three levels of individual, stand and provenance were fully differentiated and accumulated.

What should be noted when cultivating shiitake mushrooms off-season?
Shiitake mushrooms cultivated off-season can usually fruit in spring; such shiitake mushrooms are of good quality, fetch a high price, and have a good market. To develop shiitake cultivation in the future, the number of off-season crops must be increased, so that supplies are available to the market year-round and economic returns can also be raised. The principles and methods of off-season cultivation are basically the same as those of spring cultivation, but the following four points should be noted: 1. Inoculation season: inoculation should be carried out when the local average temperature is steadily below 10°C. 2. During the spawn-running process, the temperature requirement of 7-13°C should be met as much as possible; spawn running can be carried out in a greenhouse or a single-board machine room (referring to a room with a temperature of 0-13°C).

Seven points to note for preventing miscarriage in doe deer
Miscarriage prevention for deer should begin at mating and end at fawning. To ensure rapid fetal development in deer, the following tasks should be done well for miscarriage prevention. 1. Prevent inbreeding. Inbreeding increases the chances of embryo death and the birth of deformed deer. It also easily causes low viability in fawns, leading to reduced productivity. 2. Strengthen the taming of deer, enhance their docility, and prevent mechanical miscarriage. 3. Improve the living environment of doe deer. Promptly clear snow and ice from the deer shed. Prevent deer from slipping and suffering miscarriage.

What nutritional points should be noted when raising piglets in spring and summer?
From March to June, temperatures gradually rise, which is exactly a favorable period for developing pig production. Four issues should be noted in feeding. First, pay attention to temperature changes. In spring and summer, temperatures vary greatly, there is more rain, and humidity is relatively high. Pigs prefer a dry environment, have little fat tissue, and piglets are prone to feeling cold. Therefore, the temperature inside the shed and the dry environment of the pen should be maintained. Second, pay attention to increasing protein feed. Especially for piglets that have undergone long-distance transport, because they are stimulated by wind, cold, and the bumps of vehicles and boats, some piglets

Things to note when potting and repotting azaleas
Azaleas should be potted once the cuttings have taken root. For pots, clay pots with good permeability are best, purple sand pots come second, and glazed pots and porcelain pots are the worst. When potting, pay attention to choosing the size of the pot, and never use a large pot for a small seedling. If the pot is too large, the potting soil stays wet for a long time, aeration will be poor, and at the same time the roots can easily fail to reach the pot wall, affecting the development of the seedlings. Generally, for rooted cuttings you can choose a clay pot with a diameter of about 10 cm, and after one year repot into a flower pot of about 15 cm. When potting, pay attention to making a good drainage layer: first cover the drainage hole with a piece of tile, then put

What issues should be noted when harvesting sweet potatoes?
Sweet potato is a vegetatively propagated vegetative body, with no obvious maturity standard or harvest period, but harvesting too early or too late affects the yield, seed retention, storage, processing and utilization, and crop rotation of sweet potatoes. Harvesting too early will significantly reduce the yield of sweet potatoes; harvesting too late, sweet potatoes are often affected by low-temperature chilling injury, are not resistant to storage, and the drying rate declines. Therefore, sweet potatoes must be harvested at the right time. The suitable harvest period for sweet potatoes should be determined according to climatic conditions, safe storage time, and the arrangement of the following crop. When the ground temperature is around 18°C, the weight increase of sweet potatoes is very small; when the ground temperature is

What should be noted when advancing the cotton sowing date?
Can the cotton sowing date really be advanced? Based on many years of cotton sowing practice, the lessons in this regard are very profound. It is true that using plastic film mulching for nutrient-pot seedling raising can also allow sowing in mid-to-late March and produce cotton seedlings in early April, and large-scale demonstrations have been carried out in production, but the result is that management is very difficult, and it is also hard to ensure full stands and strong seedlings. First, cold waves are frequent in early to mid-April, temperature fluctuations are large, north winds occur many times, and it is very difficult to judge when to uncover and cover the seedbed film; second, if continuous rainy weather occurs, it is difficult to ventilate the cotton seedlings on the seedbed, which very easily leads to spindly seedlings and causes cotton seedlings to lodge; third, low temperature and rain also easily induce diseases such as damping-off, anthracnose, and seedling blight, causing patches of dead seedlings in the seedbed; fourth, early sowing prolongs the seedling age of cotton seedlings, forcing them to be transplanted into the field too early. When early-transplanted cotton seedlings encounter cold waves, missing plants and broken rows often result from dead seedlings, generally 10%-20% missing plants, and in severe cases 30%-50% missing plants. In recent years, many new varieties have been introduced in cotton production, especially hybrid insect-resistant cotton, which is relatively expensive. If the area of missing plants is too large, it will not only cause economic losses, but also make it difficult to achieve one sowing, one transplanting, and one full stand of cotton. The planned cotton field area often cannot be realized, and it is even harder to ensure that excellent cotton seed is planted to achieve a high and bumper harvest.

What should be noted when giving injections to a sick turtle?
For captive-bred turtles that fall ill, treatment methods such as oral medication, injections, applying medicine, or even medicated baths can be used. Among these, injecting the medicinal solution directly into the turtle's body works fastest and most effectively. However, turtles have a shell for protection and more bone than flesh, so the following points must be noted when injecting a turtle, otherwise it is easy to cause harm to the turtle. 1. Choose the correct injection site. The leg muscles of the turtle's front and hind limbs are relatively plump, so intramuscular injections are generally given there. When injecting, the needle should preferably enter at a 45° angle to the limb; too large an angle will damage the fascia or bone

What are the key points to note for garlic planting in 2010
The garlic planting area in Eryuan County has remained at around 50,000 mu year-round. Thanks to the unique natural climate conditions and cultivation techniques, the garlic produced there bolts early, reaches the market early, and has a high rate of single-clove garlic. Garlic cultivation yields high output value and good returns, and the garlic industry plays a positive role in increasing farmers' income and helping them prosper. In order to promote the healthy and steady development of the garlic industry and effectively protect the interests of the broad community of garlic farmers, in accordance with the provisions of the Seed Law, the Measures for the Administration of Crop Seed Labels, and the Measures for the Supervision and Administration of Quantitatively Packaged Commodities, and in conjunction with Dali Prefecture Agricultural Office Document
