Large flat apricot is an excellent tree species for village and township greening
Large flat apricot is a plant of the genus Prunus in the Rosaceae family and is an economic tree species unique to our country, originating from the Zhangjiakou area of Hebei Province and the suburbs of Beijing. In 2002, Liaozhong County of Shenyang City introduced nearly ten thousand large flat apricot seedlings for trial planting, and since 2006 has carried out large-scale promotion and cultivation; at present, the whole county has planted nearly 2000 mu of large flat apricot, and the growth is good. The excellent characteristics of large flat apricot: strong adaptability: cold-resistant and drought-resistant, tolerant of barren soil. It can grow normally whether in plains, mountains, hills, or sandy, barren, saline-alkali land. Early fruiting and high yield. Long fruiting period: two to three years after planting

What are the key technical points for flat-planting narrow-row dense planting of soybeans?
Key technical points for flat-planting narrow-row dense planting of soybeans: 1. Seed and treatment: For variety selection, choose suitable varieties according to the local ecological type and local conditions. 2. Seed quality: It must reach Grade II improved seed or above under the seed grading standard. 3. Seed treatment: Use seed coating agent for seed dressing, selected according to the types of pests and diseases and soil conditions. 4. Rotation and tillage land preparation: For crop rotation, use a rotation of more than 3 years, do not plant continuously or on adjacent stubble, and the previous crop should mainly be wheat-type crops. For tillage, adopt mainly deep loosening, combining loosening and harrowing, to facilitate drought resistance and moisture conservation. 5

Key Cultivation Techniques for Soybean Deep Loosening, Narrow-Row, Flat Sowing and High-Density Planting
Soybean deep loosening, narrow-row, flat sowing and high-density planting is another "new high-yield cultivation model" following "ridge three" and "large ridge density." It integrates advanced techniques such as deep loosening and rotary tillage for seedbed preparation, uses fertilizer to support density and density to increase yield, increases the canopy leaf area index, and improves light interception rate, achieving cost savings and efficiency gains in soybean production. Over two years, Luobei County promoted and planted 16000 mu in Tuanjie, Fengxiang, Zhaoxing and Taipinggou, with an average yield of 206 kg per mu, a 43% increase over the control.

Introduction to Ruipan 21, a new extremely late-maturing flat peach variety
The fruit is oblate and uniform in size, with an average single-fruit weight of 236 g and a maximum fruit weight of 294 g. The fruit apex is sunken and basically does not split; the suture line is shallow, and the stalk cavity is shallow. The ground color of the skin is yellow-white, with a purplish-red blush covering 1/3 to 1/2 of the fruit surface; the skin is difficult to peel, and the fuzz is thin. The flesh is yellow-white, thicker at the end away from the suture line, with no red streaks beneath the skin and red coloration near the stone. It is a hard-melting type, with relatively abundant juice, few fibers, a sweet flavor, and fairly firm texture, containing 13.5% soluble solids. The stone is relatively small and clings to the flesh (clingstone). In the Beijing area, buds break in late March, flowers bloom in mid-April, and the fruit ripens in late September,

What causes aflatoxin poisoning in pigs
Aflatoxin is a toxin produced by Aspergillus flavus. It is not easily destroyed in the external environment, and ordinary heating and boiling cannot break down the toxin (Bt toxin is only broken down when heated to 268°C to 269°C). It is a liver-cancer-causing substance. Aspergillus flavus is widely distributed in nature and readily parasitizes and multiplies in corn, peanuts, rice, wheat straw, as well as cottonseed cake, soybean cake, wheat bran and rice bran, producing toxins and causing ordinary grains and their by-products to become moldy and spoiled. At present,

Detailed Explanation of the Pathogenic Characteristics of Duck Aflatoxin
(1) Production of aflatoxin Aflatoxin, like other mycotoxins, is one of the metabolic products produced by toxigenic fungi during their growth and reproduction in a substrate. This toxin was discovered in 1960 during the investigation of the cause of "Turkey X disease" that affected 100,000 turkeys in the United Kingdom. The following year, it was further found that peanut meal contaminated with Aspergillus flavus could induce liver cancer in rats, confirming that aflatoxin is a carcinogenic mycotoxin. The main fungi producing aflatoxin are specific strains of Aspergillus flavus and Aspergillus parasiticus, while Aspergillus wentii and

What are the prevention and treatment methods for aflatoxin poisoning in pigs?
1. Cause: Corn, soybeans and cottonseed are all easily infected by Aspergillus flavus. At the suitable temperature of 24°C-30°C and a relative humidity above 80%, it can multiply in large numbers and produce this toxin. When the above seeds and their by-products are used as feed to feed pigs, poisoning can occur after about 15-25 days. 2. Symptoms: In acute cases, pigs may be seen falling to the ground and dying during movement, or dying within two days after symptoms appear. Sick pigs do not eat, the mucous membranes are pale, the hindquarters are weak, walking is unsteady, the feces are dry, and there is bleeding from the rectum. Sometimes sick pigs press their heads against the wall.
