Shallow water warming for rice to promote tillering, fertilization with "two preventions" to grow strong seedlings
Due to the impact of unfavorable weather conditions such as low temperatures, frequent rain and insufficient sunlight, rice has been slow to turn green, with yellow leaves, few tillers and delayed growth. For this reason, rice expert Xu Yirong, after an on-site inspection in the Heilongjiang reclamation area, proposed countermeasures such as shallow water warming to promote tillering, fertilization with "two preventions" to grow strong seedlings, and fitness-based disease prevention. First, water layer management must be done well: deep water is a heat-preservation measure, shallow water is a warming measure, and not establishing a water layer is a cooling measure. For plots with deep water formed by rainfall, drainage must be carried out promptly to raise temperature, promote root growth and promote

How to prepare fish? Learn easily with a seven-step method
Preparing fish before eating is crucial. If it is not done properly, it will cause a lot of inconvenience in cooking, and sometimes it will make the fish taste terrible, or even make it impossible to swallow. Now I will teach you the preparation method: Washing after slaughtering a live fish: generally people can smoothly remove the fish's gallbladder, so there is not much of a problem. Nowadays people mostly ask the fish seller to help slaughter the live fish, and they do not necessarily clean it very thoroughly. Thorough washing after bringing it home is very important, so as to avoid a strong fishy smell after the dish is made. Fish gills: be sure to thoroughly gouge out all the gill filaments, to avoid

Why is intercropping tree peony root bark with Gastrodia elata so profitable?
Tree peony root bark (the root bark of the tree peony) and Gastrodia elata are both precious Chinese medicinal herbs. Intercropping Gastrodia elata in tree peony root bark fields is a new high-yield, high-efficiency cultivation model that is worth promoting to herb growers in Chinese medicinal herb growing regions everywhere. The most notable features of intercropping Gastrodia elata in tree peony root bark fields are: first, it makes full use of the land; second, the two are complementary; third, it eliminates the trouble of having to weed the tree peony root bark field frequently. The cultivation method is described below: 1. Planting tree peonies. 1. Site selection: The tree peony field for intercropping Gastrodia elata requires fertile, deep soil, and a slight slope is best.

How can Gastrodia elata in the Changbai Mountains of Jilin be protected from frost damage in years with little snow?
Wild Gastrodia elata in the Changbai Mountains of Jilin is mostly distributed in high-mountain broad-leaved mixed forests at an altitude of 500-2500 m with cool and humid summers, deep winter snow cover, high ground coverage, a thick layer of fallen branches and leaves, a relatively shallow frozen layer, and loose soil. Wild Gastrodia elata suffers frost damage in winters with little snowfall and a thick frozen layer, and cultivated Gastrodia elata also suffers frost damage when cold-protection measures are inadequate. In both 1981 and 1982, heavy snow sealed the ground, with winter snow 80 cm thick; when the snow was broken open, the frozen layer on the ground was found to be only 3 cm, so neither wild nor cultivated

How to prevent and control contaminants in oyster mushroom cultivation? Covering with burnt mud ash is effective
Bed-style cultivation of oyster mushrooms: When bed-style cultivating oyster mushrooms, if contaminants appear sporadically on the surface of the substrate, they can be eliminated by smearing or covering the affected spots with thick quicklime slurry; if contaminants appear in large amounts on the substrate surface, cover the contaminated part with 2-3 cm thick burnt mud ash, making the covered area larger than the contaminated area, and pat it slightly firm to eliminate the contaminants; if contaminant contamination on the substrate surface is severe, cover the entire substrate surface with burnt mud ash and pat it firm, and after a few days the mycelium will resume normal growth. Bag-cultivated oyster mushrooms: first pick out the bags contaminated by unwanted organisms, then in a place with relatively high

What to do when oyster mushrooms grow contaminant fungi? Covering with mud and sand can prevent and control it
Contaminant fungal infections often occur during oyster mushroom cultivation, and are especially severe in hot seasons, causing reduced yields in mild cases and total crop loss in severe cases. Most of these contaminant fungi are aerobic and tolerant of high temperatures and high humidity. Covering with mud and sand can prevent and control them. The specific techniques are introduced below: 1. Prevention and control of contaminant fungi in bed-cultivated oyster mushrooms. When contaminant fungal contamination appears in large-bed oyster mushroom cultivation, the cause of contamination should first be identified. Common causes include sudden high temperatures, water entering the substrate, unclean surrounding environment, insect pests, etc. Based on the specific situation, remove the source of contamination, then treat the contaminated oyster mushrooms as follows: if contaminant fungi appear sporadically on the substrate surface, smear or cover the affected area with thick lime slurry. When a large amount of contaminant fungi appears, dig up mud and sand from more than 30 cm below the ground surface, crush it, add 2% lime powder and mix thoroughly, remove the plastic film, and cover the contaminated part of the substrate surface with the lime-mixed mud and sand to a thickness of 2-3 cm. The covered area should be slightly larger than the contaminated area, and the mud and sand should be patted slightly firm. When the substrate surface is severely contaminated, the entire bed surface should be covered with mud and sand, then covered with a plastic film that has been washed clean with disinfectant solution, and routine management should be resumed. After a few days, the mycelium will resume growth.

Detailed processing method for soy-sauce-flavored oyster mushrooms, with production steps
Select oyster mushrooms at 7-8 maturity, remove the mushroom stems, and wash clean. Using a ratio of 5 kg salt per 100 kg fresh mushrooms, place them in a vat and salt-cure for 3 days, then take them out, drain off the brine, add 10 kg salt to the vat and cure again, take them out after 7-10 days, drain off the brine, then add an appropriate amount of salt for a third curing. At this point the brine has reached 22 degrees Be, becoming a salted base that can be stored long term. Soak every 100 kg of salted base in 400 kg clean water for 8 hours, take out, drain off the water, soak in light fragrant sweet sauce for 8 hours, remove, and drain

Do not use cottonseed hulls with a high content of cottonseed kernels directly for cultivating oyster mushrooms
Cottonseed hulls consist of the hulls left after the kernels are removed from cottonseed, the short cotton lint attached to the hulls, and a small amount of broken cottonseed kernels. Cottonseed hulls are rich in nitrogen, phosphorus, potassium, cellulose and lignin, with a carbon-to-nitrogen ratio of 79-85:1, are slightly alkaline, loose outside and dense inside, have good air permeability and strong water retention, and are a top-grade material for edible mushroom cultivation. However, cottonseed hulls contain toxic substances, and after sterilization under high pressure or normal pressure they release aldehydes, ketones and acids, and these toxic substances inhibit mycelial growth, delay pinning, and cause undesirable outcomes such as small mushrooms and poor mushroom quality.

Detailed Explanation of Key Techniques for Raising Snakes Without Hibernation in Winter
Snakes have the habit of hibernating. In southern regions, snakes generally enter hibernation in November each year, lasting about half a year, which is unfavorable for the benefits of snake farming during the cold winter and spring seasons. How can this shortcoming be overcome? The best approach is to create the following conditions so that snakes do not hibernate during the cold season and continue to eat and gain weight. 1. Create a good heated room. The heated room should be sealed on all four sides, maintaining an indoor temperature between 20°C and 28°C, so as to accommodate the snake's internal body temperature. The heating room facilities are as follows: ① Use a coal stove to make a fire, with exhaust gas discharged outside. If building one to hold

High economic returns from intercropping apricot trees with Chinese medicinal herbs
In recent years, farmers in the rural areas around Luoyang, Henan, have adopted the "forest-medicinal herb intercropping" method to plant trees and grow medicinal herbs, becoming wealthy through both the "forest" and the "medicinal herbs." The soil in the Luoyang area is very high in potassium, so the kernel apricot, a potassium-loving plant, finds the necessary soil conditions to grow there. Moreover, the light, heat and moisture conditions here all suit the growth requirements of kernel apricot. Kernel apricot is cold-tolerant, light-loving and tolerant of poor soil, making it suitable for planting on semi-arid hilly slopes. After planting, kernel apricot can bloom and bear fruit in two to three years, and in four to five
