How to treat swine dysentery in winter? Detailed explanation of prevention and treatment methods
Winter dysentery is called porcine epidemic diarrhea in winter. The peak incidence period is from mid-December each year to mid-January of the following year; the disease onset is acute, spreads rapidly, and has a wide epidemic range; the incidence rate is high, the mortality rate is low, and it seriously affects the growth and development of pigs. The incubation period of the disease is generally 12-18 hours. After infection, adult pigs show symptoms of watery diarrhea. The feces are initially grayish-white, gradually becoming yellow-green, with an unbearable foul odor. Abdominal bloating, vomiting, body temperature initially rises to 40degC-41degC, and once the diarrhea passes, the body temperature drops. Thirst and desire to drink. Piglets within 10 days of age suddenly

Detailed Explanation of Key Points for Intercropping Cultivation Techniques of Gastrodia elata
1. Intercropping time. Intercropping Gastrodia elata in tree peony root bark fields should be carried out from late autumn after the tree peony leaves fall to early spring of the following year. This is both the dormant period of the tree peony and the harvest period and optimal planting period of Gastrodia elata. 2. Intercropping method. For tree peony root bark plots used for intercropping Gastrodia elata, choose plots where tree peonies have been planted for more than 1 year. First, prepare Armillaria fungus wood and Gastrodia elata seeds, and also prepare enough leaves for use as filler and mulch, then plant according to the conventional planting method for Gastrodia elata. When planting, first spread a layer of leaves between the rows of the tree peony root bark field, with a thickness of 5 cm to 10 cm

Why is intercropping tree peony root bark with Gastrodia elata so profitable?
Tree peony root bark (the root bark of the tree peony) and Gastrodia elata are both precious Chinese medicinal herbs. Intercropping Gastrodia elata in tree peony root bark fields is a new high-yield, high-efficiency cultivation model that is worth promoting to herb growers in Chinese medicinal herb growing regions everywhere. The most notable features of intercropping Gastrodia elata in tree peony root bark fields are: first, it makes full use of the land; second, the two are complementary; third, it eliminates the trouble of having to weed the tree peony root bark field frequently. The cultivation method is described below: 1. Planting tree peonies. 1. Site selection: The tree peony field for intercropping Gastrodia elata requires fertile, deep soil, and a slight slope is best.

What effect does low winter temperature have on Gastrodia elata
The tubers of Gastrodia elata are buried underground and overwinter in a dormant state; the stable low temperature they can tolerate is 0-5°C. However, if winter temperatures fluctuate frequently, with large swings in temperature difference, sudden warmth followed by sudden cold, Gastrodia elata is prone to cold damage. Therefore, special attention should be paid to cold protection and heat preservation for overwintering Gastrodia elata, especially for box-cultivated Gastrodia elata, which should be covered even more carefully to preserve warmth and prevent cold damage. But Gastrodia elata has a certain low-temperature cycle and requires an appropriate stable low temperature in winter, otherwise its sprouting will be adversely affected.

Winter Management Methods and Technical Key Points for Gastrodia elata in Jilin Province
Jilin Province has a long, cold winter, during which Gastrodia elata is in a dormant state. Preventing freezing damage and rot in Gastrodia elata is the key to achieving a bumper harvest. ① Management of pit-cultivated Gastrodia elata. Pit-cultivated Gastrodia elata usually overwinters outdoors. Before the onset of winter, the soil moisture in the Gastrodia elata pit should be kept at 30%-40%, and excessively wet conditions and water accumulation should be prevented. Drainage ditches should also be dug around the Gastrodia elata pit to prevent snowmelt water from flowing into the pit. Before freezing, cover the Gastrodia elata pit with a 15 cm thick layer of leaves or weeds, then add 20-30 cm of cold-protection

Three things to note when cultivating oyster mushrooms in winter
Mushroom yard selection The ideal site suitable for winter cultivation is a mushroom yard with warming and insulation conditions, such as an indoor mushroom house equipped with warming conditions, a warmer underground mushroom yard, and a raised-bed mushroom yard using plastic greenhouse cultivation, etc. The temperature of this type of mushroom yard can be controlled above normal temperature, which is beneficial to mycelial growth and can also promote earlier fruiting. Usually, for early winter cultivation, an outdoor mushroom yard can be chosen; for late winter cultivation, an indoor mushroom house should be chosen. Strain selection Winter-cultivated oyster mushrooms can be divided into two types according to the fruiting period arrangement: winter cultivation with winter fruiting and winter cultivation with spring fruiting. For the former, low-temperature type varieties

How to prevent deformed mushrooms when growing oyster mushrooms in winter?
When cultivating oyster mushrooms in winter, poor management can easily lead to various deformed mushrooms, reducing their commercial value and thus lowering economic returns. 1. Big-foot mushroom: after the primordia form, the differentiation and development speed of the cap is inconsistent, showing only growth of the stem, thick at the bottom and thin at the top, with no mushroom umbrella forming; the diameter of the cap is smaller than the diameter of the stem, forming a big-foot deformity. The stem of this kind of mushroom is relatively hard, and its commercial value is relatively low. Preventive measures: pay attention to ventilation and reasonable watering. Even during continuous low-temperature weather, during the fruiting period you should still take advantage of the warmer time of day to carry out short periods of ventilation.

Key Cultivation Techniques for Interplanting Oyster Mushrooms in Pear Orchards
After the pears are harvested, the pear orchard has a relatively long fallow period. Using the empty rows between pear trees to grow one season of oyster mushrooms can yield good returns. 1. Choosing the bed site: It is best to choose a pear orchard relatively close to the village, with good soil quality, convenient irrigation and drainage, and smooth transportation. 2. Carefully preparing the beds: The mushroom beds are 8-10 m long and 1.2 m wide. The bed soil should be plowed 15-20 cm deep and carefully prepared so that the soil is loose and free of weeds, loose on top and firm below, forming a ball when squeezed by hand and breaking apart when dropped on the ground. Build a ridge 4-5 cm high around the bed surface to conserve moisture. After the mushroom beds are prepared, dig drainage

Benefits and Cultivation Techniques of Interplanting Oyster Mushrooms in Pear Orchards
After the pear trees are harvested, the pear orchard has a fairly long idle period. Using the empty rows between the pear trees to grow a season of oyster mushrooms can yield good economic, ecological and social benefits. A seedbed of about 10 sq m can produce more than 100 kg of oyster mushrooms, with an income of more than 200 yuan, requiring little input and giving quick returns; it can also increase fertilizer sources, improve the soil, build up soil fertility and raise the phosphorus and potassium content; at the same time it can kill off winter weeds; and it is beneficial for the pear trees' second autumn root growth. To successfully interplant oyster mushrooms in a pear orchard, the following points of cultivation technique should be mastered. 1. Choosing the bed site

Correct methods for winter topdressing of edible mushrooms
(1) Crush poultry manure, add 1.5 times its volume of water, ferment for 10 days, boil for 10 minutes, then dilute with 3 times the amount of water and spray. (2) Boil 10%-30% human or livestock urine or 1% glucose to sterilize, filter, and pour onto the bed surface. (3) Spray with 1% superphosphate, 0.5% urea, 0.2% ammonium sulfate, or compost extract. (4) Chop carrots and cabbage leaves, add water and boil until soft, filter, then dilute with 4-5 times the amount of water and spray. (5) 500 grams of soybean flour, add 25
