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.

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,

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

What are the three key points for storing Gastrodia elata seeds in winter?
1. Harvesting. From late October to the end of November, while harvesting commercial Gastrodia elata, also harvest the tuberous root seeds. Select fresh, pest- and disease-free, undamaged small white Gastrodia tubers, air-dry them for 1-2 days to remove some moisture, then gather and store them for use as seeds the following year. 2. Temperature. Place the Gastrodia tubers, after some moisture has been air-dried off, in layers inside a wooden box, brick pit, or large earthen basin. Cover each layer with moist sandy soil. First spread a base layer of yellow sand, then place a layer of Gastrodia seeds on top, and repeat this for 4-5 layers. The storage temperature should be kept at 2-5°C. Do not let the temperature

Prevention and Treatment of Common Pig Diseases in Autumn and Winter
With the arrival of autumn and winter, the occurrence and spread of pig diseases differ markedly from summer. First, as temperatures drop, the probability of viral diseases increases greatly (such as swine influenza, transmissible gastroenteritis, classical swine fever, and foot-and-mouth disease in pigs). At the same time, because of the need to keep warm, increased stocking density and poor ventilation lead to frequent outbreaks of respiratory diseases (such as porcine respiratory disease complex, enzootic pneumonia, and porcine reproductive and respiratory syndrome). The occurrence of the above diseases has given rise to many new features in the epidemiology of pig diseases in recent years. This article discusses the autumn and

Prevention and Treatment of Vitamin Deficiency in Pigs in Late Winter and Early Spring
In late winter and early spring, pigs are prone to vitamin deficiency. The main reason is that green fodder is still relatively scarce; in addition, some pig farmers provide a single, unbalanced feed, and the pig houses lack sunlight and ventilation, so pigs are susceptible to vitamin deficiency in spring. The prevention and treatment methods are described below: Vitamin A deficiency. Symptoms: dry skin, dull coat, indigestion, reduced appetite, slow growth. In some cases, vision is weakened and the nerves are disturbed. In severe cases, spasms, circling, unsteady gait, incoordination of movement, and even paralysis of the hindquarters may occur. In sows

Key points for autumn and winter rearing techniques of black carp, grass carp, silver carp and bighead carp broodstock
Broodstock rearing is an important part of the artificial propagation of black carp, grass carp, silver carp and bighead carp. The feeding and management work in autumn and winter directly affects the induced spawning results of the following year, so it must be given full attention. 1. Conditions and clearing of the broodstock pond. The pond for rearing broodstock should not only be close to the spawning pond but also have good water source conditions, and be convenient for irrigation and drainage. The pond bottom should have little mud; for silver carp and bighead carp ponds, a mud depth of 20 cm is sufficient, while black carp and grass carp ponds should contain little or no mud. The area should be 2000-3300 sq m, with a water depth of about 1.5 m. Broodstock rearing
