How to Cleverly Identify Whether Fish Have Eaten Their Fill
1. Pay close attention to how long the fish take to eat at the feeding tray or feeding ground. If, after a certain amount of feed is put in (the normal feeding amount), the fish finish the feed in less than 2 hours, it means the feed is insufficient and some fish have not eaten or have not eaten their fill, so an appropriate amount should be added. If the feeding amount per ten-day period is fixed and the daily feeding amount within the period is the same, but by the end of the period the feed put in is finished by the fish in less than 2 hours, it means the fish have gained weight and the feed amount should be increased. When feeding compound pellet feed, if the feed has already been finished but the school of fish is still swimming rapidly on the surface layer searching for food and is unwilling to sink into the "second layer of water," it indicates the fish have not eaten their fill. If the school of fish has already dispersed from the feeding tray or feeding ground and there is still leftover bait, the fish have eaten more than their fill, and the feeding amount can be appropriately reduced next time.

Clever Use of Garlic Decoction for Preserving Satsuma Mandarin
In the winter of 1985, a preservation experiment on Owari satsuma mandarin (Citrus unshiu 'Owari') was carried out using Chinese herbal medicine treatments. The results showed that dipping the fruit in a 10% garlic decoction for 10 seconds had a good preservative effect. The Chinese herbal medicine formulations tested were: (1) 10% decoction each of Schizonepeta tenuifolia, dandelion, galangal, Sichuan pepper, and zedoary (abbreviated as the five-ingredient mixture); (2) 10% decoction each of garlic, tea seed cake, and Chinese honey locust (abbreviated as the three-ingredient mixture); (3) 10% decoction each of tea seed cake and Chinese honey locust (abbreviated as the tea-honey locust liquid); (4) 10% tea seed cake decoction

Clever inoculation of shiitake mushrooms: master the method to achieve high yields
1. Dense inoculation increases the spawn points on the log segments. More spawn points means a larger area of spawn growth, allowing the mycelium to penetrate deep into the log segments and feed within a shorter time, reducing the chance of contamination by competitor fungi. 2. Deep inoculation: deeper spawn holes hold more spawn, which helps enhance drought resistance and reduces the stimulation of external temperature differences on the spawn blocks at the bottom of the holes. Under constant temperature and humidity, the mycelium inside the spawn blocks germinates quickly, and the survival rate improves. Drilling deeper holes increases the tangential depth of the wood, greatly raising the yield. 3. Early inoculation: under low-temperature conditions, the density and activity of competitor fungi in the air are low,

How to control edible mushroom pests? A few clever methods to teach you
(1) Mix sugar, vinegar, baijiu (Chinese liquor), dichlorvos and water in a ratio of 2:3:4:1:90 to make a sweet-and-sour medicinal solution.
