How to Store and Keep Sweet Potatoes Fresh? A Full Breakdown of the Technical Points
Sweet potato (Ipomoea batatas) is a traditional product of Shanting District. Since 2000, 3 townships in this district have processed sweet potato jujube for foreign trade companies every year, with an annual processing volume of 1.6 million kg of sweet potato jujube, and have thus developed a set of sweet potato cellar storage and preservation techniques with very good results. The key technical points are introduced as follows: 1. Cellar. Choose a place with relatively high terrain and soil mainly of red loam to build the cellar. The depth of the cellar is preferably about 3 m, and the two storage chambers for sweet potatoes should be no less than 1.8 m in height and no less than 2.5 m in length and width.

Key points of adlay cultivation techniques, a full analysis of planting methods
Adlay has a wide range of uses and can be used both as medicine and food. It is a top-grade tonic, and one of the treasures in eight-treasure porridge is adlay kernels. Adlay is also a rare raw material for handicrafts. Adlay bead curtains strung from it are beautiful and elegant, a brilliant sight among hanging curtains. 1. Seed treatment. Before sowing, choose sunny weather, spread the seeds evenly on the floor to dry, and turn them often, drying them for 1-2 days. Put the dried seeds into cold water and soak them for 10-16 hours so they fully absorb water, which helps germination. Dress the seeds with 20% thiophanate,

How to raise pullets for egg production successfully? Detailed explanation of key technical measures
When chicks are 7 weeks old, they are moved into the growing house and enter the growing stage. Whether this stage is successful or not largely determines the physique and laying performance of laying hens after sexual maturity. Therefore, to raise high-yielding replacement laying hens that meet breed requirements, the key link is to do a good job in the feeding and management of growing chickens. 1. Do a good job in disinfecting the environment inside and outside the chicken house to create a relatively safe living environment for the flock. Many diseases on laying hen farms are caused by horizontal transmission. Therefore, disinfecting the chicken house, the surrounding environment, and the chickens themselves to cut off the links of horizontal disease transmission is an effective way to control disease occurrence and reduce chicken deaths. The specific technical measures taken are: ① Two weeks before introducing the chickens, first thoroughly clean and wash the chicken house, then wash and disinfect it with disinfectants such as Baidusha or Aidifu. ② Use formalin plus potassium permanganate for fumigation disinfection at a ratio of 30 ml plus 15 g, keep it sealed for 1-2 days, and pay attention to increasing the temperature and humidity of the chicken house to improve the disinfection effect. ③ One day before introducing the chickens, spray disinfect once with Youlüjing or iodine preparation disinfectant, and disinfect the floor with a 1%-2% caustic soda solution. ④ After introducing the chickens, carry out disinfecting with chickens present 1-2 times per week, alternating disinfectants to avoid the emergence of drug resistance. In seasons with frequent disease, disinfect 2-3 times per week. In hot summer, disinfect once a day, which can also play a certain role in preventing heatstroke and cooling.

Biotech pigs capable of producing a cerebral thrombosis treatment drug have been successfully bred by South Korean scientists
South Korean scientists have successfully bred "biopigs" that produce a cerebral thrombosis (cerebral hemorrhage) treatment drug through their urine. The South Korean Rural Development Administration recently stated: "By injecting the genetic gene for treating cerebral thrombosis (TPA) into pig fertilized eggs, we successfully bred 4 pigs that can excrete cerebral thrombosis treatment substances through their milk and urine." South Korea has become the world's second country after the United States to breed, through genetic modification, animals capable of producing cerebral thrombosis treatment substances. The United States, in 1997, through genetic modification technology,

Many Methods for Propagating Goji Berry: A Full Analysis of Commonly Used Propagation Techniques
1. Seed propagation: Spring sowing should be carried out from late March to mid-May, when temperatures rise noticeably. Soak the seeds in 30°C warm water for 24 hours, then rub them, pick out the flesh and skin, take out the sunken seeds, and dry them. Mix the seeds with wet sand at 1:3, then place them indoors at about 20°C to germinate, keeping them moist. When about 30% of the seeds have cracked and shown white, germination is complete. For the nursery site, loam or sandy loam near a water source can be chosen as the seedbed. It requires flat terrain, good drainage, and ample sunlight. Apply 5000 kg of decomposed barnyard manure per mu

Why do mushrooms sporadically appear before the mycelium has fully spread
Normally, after the mycelium has fully spread, fruiting begins after a few days of recovery. But sometimes fruiting bodies appear when the mycelium has only spread through 2/3, or even 1/2, of the mushroom log, which is abnormal. Some people advertise that their spawn produces mushrooms before the mycelium has fully spread as a superior "early-maturing, high-yielding spawn," but that is deceptive nonsense; in reality, when this happens, it is a sign of spawn degeneration. There are also external factors, such as: (1) using too much spawn, so old spawn blocks produce mushrooms. (2) packing the substrate too tightly, and the cultivation bag

Full process detailed explanation of the processing technology for Baizhi mushroom strips
I. Origin of the name: Baizhi mushroom strips, whose full name is "Siwei Baizhi mushroom strips," are named after the beef tripe-like food. They are made by cutting oyster mushroom caps into long mushroom strips 0.5-1 cm wide, resembling white beef tripe, and the flavor is mildly salty, mildly spicy, mildly sweet, and mildly sour as a ready-to-eat food or convenience food. II. Process flow: rinse oyster mushrooms -> shred and rinse -> color protection and blanching -> cool and fill jars -> pour in broth and seal -> sterilize and cool. III. Basic operating procedure: (1) Shred the caps. Harvest large oyster mushrooms at less than 80% maturity,

Garlic-Ginger Intercropping Brings Good Returns: A Full Analysis of the Planting Advantages
In the history of Zhucheng City, Shandong Province, ginger was mostly grown as a sole crop. Trials and demonstrations of garlic-ginger intercropping began in the 1980s and achieved relatively good economic returns. However, because the intercropping techniques were not fully matched, for example no intercropping rows were left, the intercropped ginger bulbs became smaller, and some even failed to meet export standards, which dampened ginger growers' enthusiasm for intercropping. In order to explore the cultivation techniques for garlic-ginger intercropping, the author carried out multiple trials and survey analyses from 1992 to 1995 in Chengguan Town, Lubiao Township and other places, and summarized a matched set of techniques suitable for local garlic-ginger intercropping. After extension, a double

How to control thrips in scallion fields? A full analysis of control methods
Thrips are one of the important pests damaging Welsh onions. Adult and nymph thrips use their rasping-sucking mouthparts to damage the plant's heart leaves, tender leaves and tender buds, sucking sap, causing many fine, densely packed, continuous silvery-white streaks to form on the leaves, with leaf tips drying up, and in severe cases making the leaves unfit for consumption, greatly affecting the yield and quality of Welsh onions. The thrips damaging Welsh onions mainly include onion thrips, tobacco thrips and rice thrips, etc. They often occur mixed together, and their peak damage period is from May to September. Thrips are tiny, ranging from light yellow to dark brown, and this insect can
