Detailed Explanation of Key Technical Points for Autumn Management of Fingerlings
Autumn water temperatures are suitable, making it the peak season for fingerling growth. The following tasks should be carried out well in autumn fingerling management. 1. Timely pond clearing. After 2 to 3 months of fingerling cultivation, pond water quality tends to deteriorate, natural food organisms decrease, and harmful substances such as hydrogen sulfide and pathogenic bacteria increase. After the beginning of autumn, fingerlings should be transferred to ponds that have been cleared and disinfected for cultivation, purifying the aquaculture environment. 2. Scientific feeding. Autumn climate is suitable, fingerlings have a large food intake and grow rapidly, so feed supply must be guaranteed. For grass carp fingerlings as the main species, with silver carp

What are the key technical points for autumn management of fingerlings?
In autumn, the weather turns cold and then warm again, and the water temperature is suitable. This is the peak season for fingerling growth. Doing a good job of autumn fingerling management is a direct means of improving economic returns. The author believes that the following tasks should be done well in autumn fingerling management techniques. 1. Clear the pond in time. Generally speaking, for ponds that have been used to raise fingerlings for 23 months, the water quality will deteriorate, natural feed will decrease, and harmful substances such as hydrogen sulfide and pathogenic bacteria will increase. After the beginning of autumn, fingerlings should be transferred to ponds that have been cleared and disinfected for cultivation. In places where there are difficulties in water source and pond turnover, all fingerlings can be transferred out for temporary holding,

How to skillfully manage late-season wheat? These technical points must be mastered
Ensure sufficient soil moisture and base fertilizer. For late-season wheat, never rush to sow by seizing moisture; on the premise of ensuring adequate soil moisture, apply heavy base fertilizer, and where conditions permit, apply 3-5 cubic meters of high-quality farmyard manure per mu; at the same time, according to yield requirements, mix 2/3 of the total nitrogen, phosphorus and potassium chemical fertilizers invested throughout the growth period with farmyard manure, spread them on the surface and plow them into the soil. Choose the right variety and increase the seeding rate. Late-season wheat is suitable for semi-winter varieties, which can be selected according to local conditions. At the same time, determine the actual number of days of late sowing according to local autumn temperatures. Generally, it is advisable to increase the seeding rate by 0.5 kg for each day of delayed sowing, and never

Key Technical Points for Late-Stage Management of Mature Prickly Ash Orchards
I. Strengthen management during the flowering and fruiting stages. (1) Boron spraying at flowering: During the full-bloom stage of prickly ash, spray 1-2 times with a 0.3% borax solution, which can noticeably increase the fruit-setting rate. (2) Use of prickly ash reddening agent: Applying a reddening agent can promote coloring of prickly ash and increase yield. 7-10 days before harvesting prickly ash, spray the trees 1-2 times with a 200-fold dilution of the reddening agent, so that the ripening period of prickly ash becomes relatively more concentrated, picking efficiency increases by an average of more than 2 times, the peel is bright in color, the peel yield rate increases by 3.3%, and the yield per plant increases by 23%. (3) Timely

How to Process Feed for Mink and Foxes? A Detailed Explanation of the Technical Points
Fur animals such as mink and foxes have well-developed canine teeth, a short digestive tract, a small stomach volume, no cecum, and fast food passage through the digestive tract; moreover, their digestive glands secrete little amylase and more lipase. Therefore, their feed should be based mainly on animal-based feed, and especially animal protein feed should account for a very large proportion of the diet. Thus, the feed processing and preparation methods for mink and foxes have distinct characteristics, which are introduced below: 1. Material selection. Large pieces of fat should be removed from meat feed, the gallbladder and thyroid should be removed from livestock and poultry offal, and lumps, impurities or foreign matter should be picked out of dried animal powder and grain powder.
