Key Techniques for Overwintering Management of Panax notoginseng Seedling Fields
Panax notoginseng is a perennial herbaceous plant. Once winter arrives, its above-ground parts all die back. At this time, the above-ground parts should be cut off 3 cm above the ground, and all dead branches, fallen leaves, diseased plants and weeds in the field should be cleared away and burned outside the field. The soil should be thoroughly sprayed and disinfected with 0.2-0.3 degrees Baume lime-sulfur mixture, and then a layer of decomposed farmyard manure should be applied at about 1500 kg per mu to keep warm and prevent freezing. If exposed roots are found, soil should be banked up when the winter fertilizer is applied, and finally a layer of grass should be spread on top to ensure the buds overwinter safely.

How to Prevent and Control Common Diseases in Pigs in Winter and Spring
This disease is an infectious disease of piglets caused by Salmonella. Piglets aged 1-4 months have high morbidity and mortality rates. The disease occurs in endemic or sporadic form, often in cold, changeable weather and rainy seasons. Poor environmental hygiene and reduced resistance of piglets can induce this disease. Symptoms and lesions: In the initial acute onset, it is similar to swine fever and requires comprehensive judgment combined with other examinations. The typical symptom is persistent diarrhea with a chronic course, and some piglets also show pneumonia symptoms. Lesions: Acute cases often die of shock, with purple congestion at the extremities and systemic septic

How to prevent diarrhea in pigs in winter? These measures need to be mastered
1. Strengthen feeding management. The feed quality should be good, and mold and spoilage should be prevented, so that sows do not transmit it to piglets through colostrum and cause them to have diarrhea. Pay attention to keeping the pig herd warm during the cold season from late autumn to early spring. 2. Strengthen immunization. Pregnant sows should be injected with the vaccine for this disease 45 days and 15 days before farrowing respectively, and then ensure that piglets receive enough colostrum so that they obtain relatively high antibodies. 3. Pay attention to hygiene and disinfection. Strictly prohibit the entry of outside vehicles, purify the air, avoid infection by viruses and bacteria, and reduce pigs

The best time for fattening geese is at the turn of autumn and winter.
Goslings raised in spring and summer grow into medium geese by late autumn and early winter. After medium geese are selected and evaluated, those that cannot be kept for breeding should be transferred to the fattening period in good time, to promote fast growth and weight gain, so the geese can be fattened in winter and sold on the market. The advantages of doing this: first, the weather in winter is cold, so after geese are slaughtered, they are not prone to spoilage and are easy to store; second, this is also when the Spring Festival approaches, when demand from the market and the public is large, sales channels are broad, prices are high, and the economic benefits of raising geese are good. The rapid fattening methods for geese are as follows: the fattening feed formula is 30% dried sweet potato, 40% corn,

Autumn and winter nourishment is not the same as fish and meat medicinal diets
Autumn and winter nourishment ≠ fish and meat medicinal diets! Chinese people have had the custom of nourishing the body in autumn and winter since ancient times. With social development and rising living standards, autumn and winter nourishment is no longer simply equated with ginseng plus astragalus, and the way of nourishing should change. A balanced diet is the foundation. We all know that protein, carbohydrates, fat, vitamins and minerals are all nutrients the human body needs. However, many people's daily diets are very unbalanced, with unreasonable combinations of meat and vegetables, too little grains and coarse grains, and too much meat. Combined with a lack of exercise, this has led to steadily rising incidence rates of high blood pressure, diabetes and obesity.

High-yield cultivation technique for three successive crops intercropped in jujube orchards
The jujube tree (Ziziphus jujuba) has relatively strong growth adaptability and is a tree species that prefers warmth and light. When the spring temperature reaches 13-15°C, it begins to sprout branches; when the monthly average temperature is above 17°C, flower buds begin to differentiate; when it is above 2O°C, it flowers; the suitable temperature for fruit ripening is 18-22°C; when the temperature drops to 15°C, it begins to shed leaves. Because of its characteristics of late sprouting, early leaf fall, and little shading, it is suitable for intercropping with grain, cotton, and vegetables, and the economic benefits are very considerable. The following introduces the high-yield technique for interplanting three successive crops in one year in a jujube orchard. 1. Key points of jujube cultivation techniques

How to grow jujube intercropped with cotton? Detailed key points of orchard-style cultivation
In the Aksu region, a three-dimensional planting method of orchard-style jujube-cotton intercropping is practiced, which both promotes the growth of young jujube trees and ensures the yield of intercropped cotton, making it a relatively good cultivation model for improving planting economic benefits. 1. Cultivation indicators 1. Cotton The suitable variety is Zhongmian 35, with an average harvested plant number of 11,000-12,000 plants/667 sq m, 5.5-6 bolls per plant, 5.0-5.5 g per boll, a lint percentage of 38%-40%, a pre-frost flower rate of >=85%, and a lint cotton yield per 667 sq m of

Key Technical Points for Winter Management of Agaricus bisporus
In the Yangtze River basin and the northern provinces, such as Shanghai, Zhejiang, Jiangsu, Sichuan, Anhui and other provinces and municipalities as well as the Northeast region, because of the cold winter, the temperature in the mushroom houses is all below 5°C, which is not suitable for mycelial growth; the mycelium is in a dormant state and cannot supply the nutrients needed for fruiting body growth, therefore, mushrooms will not grow either. Generally from late December to early March of the following year, the mushrooms are in the overwintering stage. Doing a good job of overwintering management is a necessary condition for obtaining a high yield of spring mushrooms. (1) Preparatory work before overwintering ① After the autumn mushroom harvest ends, first of all, do a good job of tidying the bed surface

Detailed Explanation of Key Management Techniques for Angelica sinensis During the Overwintering Period
For directly sown Angelica sinensis (Chinese angelica), in combination with topdressing before winter, cover the seedlings with manure-enriched soil or add a layer of fine soil about 1 cm thick over the seedlings to protect them from frost damage; for seedling-raised and transplanted Angelica sinensis, seedling storage work must be done well in winter; for seed-bearing Angelica sinensis, in order to improve seed yield and quality, before harvest, robust and uniform seedlings grown on high mountains or mid-mountain slopes must be selected for seed production. Afterwards, cut off the aboveground parts of the seed-bearing plants, remove all weeds, let them overwinter naturally, and keep watch frequently to prevent livestock from entering and trampling them, which would cause gaps in the seedlings. In early spring of the following year, if weeds are seen growing, they can be pulled out by hand; at this time, the root system covers the soil surface, so hoeing for weed control and fertilization must not be used, to avoid cutting the root system and hindering plant growth.
