What are the comprehensive utilization methods for fish processing by-products?
The fish heads, tails, minced meat, scales, skin, viscera, bones, and gall bladders left over from fish processing contain large amounts of protein, amino acids, trace elements, and vitamins. Using these protein resources, various deeply processed products can be made, including soluble edible fish protein powder, liquid fish protein feed, fish scale glue, fish skin glue, bone paste, fish protein calcium candy, bile pigment calcium salt, and bile salts. Comprehensive utilization of fish processing by-products can lower the cost of main products and increase the added value of aquatic products; it can also protect the environment, reduce wastewater and waste emissions, and achieve higher economic, ecological, and social benefits.

Detailed Explanation of Immunization Programs for Common Pig Diseases
I. Immunization program for growing-finishing pigs (1) 1 day of age: super-immunization with attenuated classical swine fever vaccine; before the piglet consumes colostrum after birth, inject one dose of attenuated classical swine fever vaccine first, and let the piglet consume colostrum 1-2 hours later; this is suitable for farms where classical swine fever frequently occurs; (2) 7-15 days of age: enzootic pneumonia vaccine; (3) 10 days of age: infectious atrophic rhinitis vaccine, intramuscular or subcutaneous injection; (4) 10-15 days of age: piglet edema vaccine; (5) 20 days of age: intramuscular injection of classical swine fever vaccine; (6) 25-

A new late japonica rice variety Xiushui 110 achieves source-sink optimization through morphological type innovation
Xiushui 110 was bred by the Yao Haigen project team of the Jiaxing Academy of Agricultural Sciences in Zhejiang Province using the hybridization method, with the combination Jia 59 Tianza/Bing 95-13. In 2001 it passed variety approval by the Shanghai Municipal Variety Approval Committee, and in 2002 it passed variety approval by the Zhejiang Provincial Variety Approval Committee. In 2004 it received a post-variety subsidy from the Ministry of Science and Technology and the Ministry of Agriculture for the selection and breeding of new high-quality specialized crop varieties and research on breeding technology. In 2004 it won the first prize of the Zhejiang Provincial Science and Technology Award. 1 Morphological type innovation, achieving source-sink optimization

Fertilization Methods and Technical Key Points for Azaleas
Azalea roots are delicate and tender, so fertilizer must be fully composted before use. Generally, fertilizer that has been composted for more than 1 year and fully fermented is most suitable. Five points should be noted when fertilizing: Feed according to the seedling. Seedlings cannot be fertilized; after 4 months, a well-composted, extremely dilute liquid manure can begin to be applied; after the plants are established and transplanted separately in the following spring, more nitrogen and potassium fertilizer should be applied to accelerate vegetative growth. At 2-3 years, during the mature stage, more phosphorus fertilizer should be added to achieve a high flowering rate and large, brightly colored flowers. In the old-age stage, more nitrogen fertilizer can be applied to promote renewal of branches and leaves, rejuvenate the plant body, and extend the plant's lifespan. Fertilize at the right time. In early

How to fertilize spider plants? Master these fertilization techniques for more vigorous growth
Spider plant, known as the "air flower," when its pot is placed on a balcony or railing, can beautifully complement other potted flowers above and below. Spider plant is also a natural purifier, able to remove harmful substances from the air. Research shows that spider plant can absorb more than 80% of harmful gases indoors, with an extremely strong ability to absorb formaldehyde. An engineer from the Indoor Environment Monitoring Center of the China Decoration Association believes that spider plant is one of the most suitable plants for placement in living rooms. Spider plant is a foliage plant that is relatively tolerant of fertilizer; if fertilizer and water are insufficient, it easily develops scorched tips and ages, with leaves turning yellow, losing

There are many varieties of orchids, and their fertilization methods differ.
Orchids have large, brightly colored flowers and a blooming period that lasts for months, making them a mainstream variety of New Year flowers in recent years. Because there are so many varieties of orchids, the fertilization methods for several main varieties are introduced below. 1. Cymbidium orchids The following three methods can be used for fertilizing Cymbidium orchids: First, mix the fertilizer in the correct proportion with the growing medium to support plant growth and development. Second, mix the fertilizer in the correct proportion into a solution and pour it into the growing medium in several applications. Third, make the fertilizer in the correct proportion into solid granules or fertilizer blocks and apply them to the surface of the growing medium. Apply more fertilizer during seasons with abundant sunlight to ensure vigorous plant growth.

Cultivation Techniques and Utilization Methods of the Chinese Parasol Tree
As an ancient native tree species, the Chinese parasol tree is mostly planted in courtyards, and it has a legendary quality because of the tale of the Chinese parasol tree attracting the phoenix. However, it is rarely used as a timber tree; according to records, its wood is used to make boxes and musical instruments. I. About the beautiful legend.

What are the traditional fertilization methods for increasing the yield of edible fungi?
When edible fungi reach the middle and late stages of fruiting, a large amount of nutrients has basically been consumed. In order to strengthen the aftergrowth of fruiting, appropriate topdressing fertilizer must be applied, which can increase the yield. Mushroom growers are advised to adopt the following measures, which will have a very good yield-increasing effect. 1. Apply mushroom soup: Collect and wash the mushroom stems and broken mushrooms cut off during harvest and processing, cut them into thin slices, add 1—1.5 kg of water per kg of material, boil for 15 minutes, take the filtered juice and add 10—15 kg of water, and spray it on mushroom trays or fungus bags. Using it at the peak of fruiting can make the fruiting bodies thick and extend

Emergency supplementary fertilization for cotton to promote plant recovery and regrowth
Yang Xiushen, a researcher at the Industrial Crops Research Institute of the Provincial Academy of Agricultural Sciences, said that since July, our province has been repeatedly hit by torrential rains, and the flooding has caused widespread inundation of farmland, inflicting severe damage on cotton. Draining water and reducing waterlogging, and emergency supplementary fertilization to promote recovery are the critical priorities of the current disaster relief and remediation effort. At the same time, weeds must be removed promptly, the soil loosened, and earth hilled up around the roots, and replanting and supplemental planting should be carried out according to the conditions of each field. Emergency removal of standing water in the fields must seize the time and adopt all necessary and possible means to quickly drain the standing water, reduce the impact of waterlogging on cotton growth and development, and lower the mortality rate of cotton seedlings. For low-lying areas, especially secondary
