Overwintering management of Panax notoginseng, Coptis chinensis, Morinda officinalis, and Ligusticum chuanxiong
Panax notoginseng: In winter, when the leaves turn yellow and wither, cut off the above-ground stems and leaves about 3 cm above the ground, collect the dead stems and leaves, remove weeds and diseased plant residues from inside and outside the garden, and burn them all outside the garden to clean the field. Then spray the bed surface with 1:1:200 Bordeaux mixture or 0.2-0.3 degrees Baume lime-sulfur mixture to fully disinfect the soil. If exposed roots are found, add appropriate soil covering. In addition, after cleaning the garden in November, apply 2000 kg of decomposed mixed fertilizer per mu at the plant roots to protect the buds through the winter safely. Before the seedlings emerge

Cotton and lily intercropping planting pattern
Cotton and lily intercropping is a cotton-field intercropping pattern widely used in coastal and riverside dryland sandy loam areas. The two crops affect each other little and are mutually beneficial in fertilizer use, but note that lily cannot be continuously cropped and must be rotated to a different crop. This intercropping pattern generally has a bed width of about 3 m, with cotton planted in wide and narrow rows, the wide row spacing being 140 cm and the narrow row spacing 50 cm, with 4 rows of cotton per bed. In the wide cotton rows, 6 rows of lily are planted, with a row spacing of 20 cm and a plant spacing of 20-25 cm, at 5000-6000 plants per mu. Cotton is raised as seedlings and transplanted, planted separately on both sides of the bed,

Cultivation Methods and Technical Key Points for Intercropping Garlic in Cotton Fields
When garlic is intercropped in cotton fields, each mu can produce 93 kg of lint cotton and 1,300 kg of garlic, with a benefit of about 3,300 yuan per mu. 1. Cotton: Use insect-resistant hybrid cotton varieties such as Kemian No. 3 and Kemian No. 6. Before sowing, deeply plow the land 25 cm, and together with plowing, apply 3,000 kg of decomposed livestock and poultry manure and 60 kg of potassium sulfate compound fertilizer per mu. Broadcast 2-3 kg of 5% phoxim granules per mu to control underground pests. The suitable sowing period for cotton in Pizhou City is around April 3. Seize sunny days to raise seedlings in double-film nutritional pots. Prepare about 3,000 pots per mu of field. After watering the seedbed thoroughly, sow dry seeds, 1 seed per pot. About 0.35 kg of coated cotton seed is needed per mu of field. After full emergence, ventilate promptly to reduce humidity and control pests and diseases, and cultivate strong seedlings. Transplant around May 12 when cotton seedlings are at the 4-leaf stage, using equal-row spacing with a row spacing of 1.2 m and a plant spacing of 33 cm, planting about 1,700 plants per mu. In mid-to-late May, together with hilling, apply 15-20 kg of urea, 50 kg of superphosphate, and 20 kg of potassium chloride per mu. Around July 20, apply flower and boll fertilizer according to cotton growth, with 30 kg of urea and 15 kg of potassium chloride per mu. In early August, apply topdressing for boll development, with 7.5-10 kg of urea per mu. Pay attention to spraying trace element solutions such as boron fertilizer and monopotassium phosphate. Use mepiquat chloride for chemical regulation 4 times: 1-1.5 g per mu at the full bud stage, 2-2.5 g per mu at the early flowering stage, 3-4 g per mu at the full flowering stage, and 3-5 g per mu after topping. Top around August 6. Pay attention to controlling the third generation of cotton bollworm, cotton aphid, mirids, red spider mites, tobacco whitefly, and other pests. Pull up cotton stalks in mid-November.

How to prevent fish from oxygen deprivation in winter? These methods you must master
In winter, although the feeding activity of fish in ponds decreases, they still need a certain amount of dissolved oxygen to maintain slow breathing. The dissolved oxygen in a pond mainly comes from the photosynthesis of phytoplankton and from oxygen in the air dissolving directly into the water. However, in the cold winter, once the pond surface freezes over, oxygen in the air can no longer dissolve into the fish pond. When heavy snow covers the ice surface, sunlight cannot shine directly into the pond water, so the green plants in the water cannot carry out photosynthesis to produce oxygen. Moreover, in winter most fish gather at the bottom of the water,

Interferon Can Reduce Mortality in Pigs with Blue Ear Disease
Interferon is a class of proteins with antiviral, antitumor and immunomodulatory functions produced by cells induced by various inducers (viruses, bacteria, macromolecules, etc.). To investigate the therapeutic effect of interferon on porcine blue ear disease, we conducted a trial from August to October 2006 on the use of interferon combined with other drugs to treat porcine blue ear disease. The trial is reported as follows. From August to October 2006, at the Animal Clinic of the Huai'an Animal Husbandry and Veterinary Station, 325 pigs confirmed by laboratory diagnosis as having blue ear disease were selected and

Cotton-lily intercropping: a commonly used cotton field intercropping and relay cropping pattern
Cotton-lily intercropping is a cotton field intercropping pattern widely used in dryland sandy loam areas along the coast and along rivers. The two crops have little mutual influence and are mutually beneficial in fertilizer use, but note that lilies cannot be continuously cropped and must be rotated to a different crop. This intercropping pattern generally has a bed width of about 3 m, with cotton planted in wide and narrow rows, wide row spacing 140 cm, narrow row spacing 50 cm, and 4 rows of cotton per bed. In the wide cotton rows, 6 rows of lilies are planted, with row spacing 20 cm and plant spacing 20-25 cm, 5000-6000 plants per mu. Cotton is raised as seedlings and transplanted, planted separately on both sides of the bed, per mu

How to raise rabbits well in winter? Good feeding management is key
Keeping warm: In a low-temperature environment, rabbits lose a lot of heat and grow slowly, which affects their development and reproduction. Therefore, the rabbit hutch should be well maintained, windows sealed tightly, and cracks plugged to keep the hutch warm. Supplementary greens: Feeding green, juicy feed in winter can enhance rabbits' appetite and promote their growth, development and reproduction. Commonly used green, juicy feeds include cabbage, radish, bean sprouts, etc., but the daily feeding amount should not be too large, otherwise it easily causes diarrhea in rabbits. Add night grass: Rabbits have nocturnal habits. In winter, the days are short and the nights are long, so night grass should be added. At the same time, increase

What are the effects and benefits of intercropping Corydalis yanhusuo with garlic
Garlic is a perennial herbaceous plant in the Liliaceae family, and is a familiar vegetable and medicinal material. Garlic contains volatile oils with a pungent taste and odor that have a strong antibacterial effect against many plant pathogenic fungi and bacteria. The pesticide "antibacterial agent 402", modeled on the synthesis of allicin, primarily has a protective effect on plants, and also has a certain therapeutic effect and systemic activity. It strongly inhibits spore germination and mycelial growth of many plant pathogens, and can effectively control downy mildew, as well as black spot, anthracnose, damping-off, red rot, and Fusarium wilt

It's the right time to plant garlic in winter, garlic farmers, don't miss out
1. Choosing and preparing the land. Garlic has string-like roots with a relatively weak ability to absorb water and nutrients, and the bulbs grow and swell in the soil, so for planting garlic you should choose loose soil that is easy to drain and irrigate, rich in organic matter, fertile and soft, and with strong water retention, such as sandy soil; good half-sand half-mud land is beneficial to the root growth of garlic. The planting site generally needs proper deep plowing, sun-whitening, and can be made into high beds or flat beds, with bed width 1-31-7 m and trench width 0-5 m. The bed mud should be broken up and the bed furrows leveled so that drainage and irrigation are convenient. 2. Applying enough base fertilizer. Garlic has a strong tolerance for fertilizer and a relatively high demand for the three elements nitrogen, phosphorus, and potassium, with nitrogen fertilizer as the main one, phosphorus fertilizer secondary, and potassium fertilizer even less important. The base fertilizer is mainly compost; mix garbage, burned soil, plant ash, etc. evenly, add 60 kg of phosphorus fertilizer, 50 kg of potassium fertilizer, or 80 kg of compound fertilizer, mix well and compost until decomposed, and apply 1800-2000 kg of decomposed organic fertilizer per mu, so as to meet the growth needs of garlic. If it is relatively fertile vegetable land, a little less can be applied.

Winter control of rice pests and diseases can yield twice the result with half the effort
In winter, rice pests and diseases are in a dormant state: pests stop feeding and pathogens stop infecting. If farmers seize this favorable opportunity to carry out control, they can achieve twice the result with half the effort. 1. Dispose of diseased rice straw. Diseased straw is the overwintering site for the pathogens of rice bacterial leaf streak, bacterial blight, rice blast and many other diseases, and is the main source of infection the following year. Before the end of March, farmers can compost diseased straw at high temperature, or process it as feed or fuel, which can greatly reduce the number of pathogens. For diseased rice straw that cannot be fully processed before the end of March,
