What are the four key rules for giving dogs calcium supplements?
In recent years, many people have begun to pay attention to their own calcium supplementation, and various types of calcium supplement products have entered everyone's life. Since people need to supplement calcium in time to meet the body's calcium needs, do our puppies need calcium supplementation? The answer is yes, and because dogs cannot express for themselves some of the physical discomfort brought on by calcium deficiency, scientifically supplementing calcium for dogs is even more important. Which dogs need calcium supplementation? Dogs of different breeds and body sizes at different

What are the advantages of using extruded floating feed to farm the four major Chinese carps?
Farming grass carp (Ctenopharyngodon idella) with extruded floating complete compound feed has many advantages, such as lowering costs, protecting the aquaculture water environment, and high utilization rate. In countries with advanced aquaculture technology such as the United States and Japan, to meet the needs of the environment and fishery production, floating aquatic feed has been widely used since the 1980s. In recent years, China has also vigorously promoted the use of floating aquatic feed, developing rapidly, and many famous, special and high-quality aquatic products have already used it in large quantities, but in the use of extruded floating fish feed to farm the four major Chinese carps, there is still

New High-Yield Cultivation Technique for Soybeans: "Four Changes and One Addition"
With the traditional tillage and sowing method for growing soybeans, the rows are narrow and the plants too dense, and combined with various other reasons, yields have long hovered around 100-150 kg. Through years of experimental research, we have worked out a new approach that can increase soybean yields by more than 40%, namely the "Four Changes and One Addition" technique. The usual measures for raising soybean yields, besides selecting new high-quality, high-yield varieties, also include paying attention to crop rotation. According to experiments, after many years of continuous cropping, soybeans show slow growth, short plants, yellowing lower leaves, early leaf drop, and few pods with small seeds. Experiments have also proven that continuous cropping (monocropping) for more than 3 years can reduce yields by 20%-30%, or even more, and 2 years of continuous cropping following a one-year break can reduce yields by more than 30%. Therefore, crop rotation and changing to a different crop are of great significance in soybean production. To achieve high-yield and super-high-yield soybean cultivation, the new "Four Changes and One Addition" cultivation technique should be implemented on this basis. The specific methods of "Four Changes and One Addition" are:

Four Disease Prevention and Control Methods for Off-Season Shiitake Mushrooms
For off-season cultivation of shiitake mushrooms, during the high-temperature, high-humidity season from June to September, there are more diseases and contaminant fungi than in winter, but as long as prevention and control measures are appropriate, ideal production results can still be achieved. Log rot disease: in production, Trichoderma (green mold) usually infects first, then forms cross-infection with multiple fungi. Prevention and control measures: strictly and standardly carry out inoculation operations, and do not let mold spores fall into the substrate. Edible mushroom inoculation purification machines are worth promoting; when inoculating, turn on the purification machine for 5 minutes before operating. The effect is similar to conventional formaldehyde fumigation, and it avoids the possibility of formaldehyde residue and irritation to the human body.

Four-spored mushroom cultivation in summer is difficult, but mastering the techniques brings high returns
Summer cultivation of the four-spored mushroom (Agaricus bisporus) is more difficult than that of the common button mushroom. If cultivation techniques are careless, or if the temperature during the fruiting period is too high or too low, failure will result. The high-yield secrets for summer cultivation of the four-spored mushroom are described below: 1. Plant early at the right time. Planting too early means low temperatures in the early stage, which is unfavorable for the growth of summer mushroom mycelium; planting too late means that timely feeding for the autumn mushroom will shorten the harvesting period of the summer mushroom. Therefore, after cleaning the spring mushroom growing room in late April, the summer mushroom compost can be pre-wetted and stacked. 2. Compost fermentation. 1. Compost formula (calculated for 110 sq m). Rice straw 2000 kg, gypsum 7

How to prepare mushroom topdressing liquid? A detailed explanation of four methods
For high mushroom yields, proper topdressing is key. Here are several methods for preparing mushroom topdressing liquid: 1. Mushroom root soup. Collect and wash the mushroom stems and broken mushrooms cut off during harvesting 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 dilute with water to 10-15 kg, which can be sprayed on 30-40 sq m of mushroom beds. Used during the peak fruiting period, it can make mushroom fruiting bodies thick and plump and extend the peak fruiting period. 2. Cow urine. Take fresh cow urine, boil until the foam disappears

Fresh mushrooms are available in all four seasons. How is that achieved?
In Yangpingsi Town, Zoucheng City, Shandong, fresh mushrooms can be eaten all year round, because the mushrooms here all grow in special mushroom houses. Mushroom houses fitted with shade nets can extend the harvest period of button mushrooms (Agaricus bisporus) into summer. And the mushroom houses kept tightly sealed even in the heat of summer are meant to let straw mushrooms (Volvariella volvacea), which love high temperatures, come to market 2 months earlier. Mushroom houses fitted with air conditioning are meant to maintain a constant temperature and humidity, so that enoki mushrooms (Flammulina velutipes) grow like chives - after one crop is cut, another crop follows. Through technological means, the north-south differences in edible fungus cultivation have been changed, and its

Four things to note when harvesting rice, don't overlook these details
The following four points should be noted before and after rice harvest. 1. Drain early. Drain the water in the paddy field as much as possible; if necessary, dig ditches to drain the water in low-lying areas early and dry the field. 2. Harvest at proper maturity. For manual harvesting, do it when more than 95% of the rice husks in the field have turned yellow, the grains have hardened, and the rice grains are translucent. Mechanical harvesting can be a few days later. 3. Mind the method. Manual cutting and drying can increase the 1000-grain weight and raise yield, while the rice grain has good market quality and a high germination rate. When using a combine harvester, it is best

Four key points for fish farming at the start of spring
1. Fertilization: In early spring, when the pond water temperature stabilizes at 8°C to 10°C, start applying additional fertilizer to cultivate natural food organisms in the water. The amount of fertilizer should be determined based on the fertility of the water and the quality of the fertilizer. Generally, apply 60 to 90 kg of human and animal manure per mu, or 100 to 150 kg of livestock manure. If chemical fertilizer is used, follow a nitrogen-to-phosphorus-to-potassium ratio of 1:1:0.5. When applying, first crush it, mix it with water, and splash it evenly over the entire pond. The total amount per mu is 3 to 7 kg, with each application spaced 5 to 10 days apart. Keep the pond water a yellowish-brown or yellow

Four Diseases to Guard Against in Golden Coin Turtle Farming
During the rearing of golden coin turtles, deteriorating pond water, excessive stocking density, mixed rearing of large and small turtles, improper feeding, cold damage and heat damage and other reasons often cause turtles to become ill or die. The four diseases that golden coin turtles are prone to and their prevention and treatment methods are introduced as follows: 1. Red neck disease. Symptoms: This disease mostly occurs in the plum rain season. Red spots appear on the diseased turtle's abdomen, the throat and neck swell, the neck stretches out and cannot be retracted, appetite decreases, and reactions become sluggish. When the condition is severe, there is bleeding from the mouth and nose, intestinal inflammation and erosion, and generalized redness and swelling, without
