Points to note when raising pigs in summer: do not throw cold water on the pigs
In summer, when the temperature is high, pigs often pant loudly from the heat. Some farmers, worried that the pigs will fall ill from the heat, throw cold water on the pigs, hoping to cool them down and make them feel more comfortable, not realizing that this is harmful and does no good. Pigs pant from the heat because their sweating is poor, so the heat in their bodies cannot be released for the time being. If cold water is thrown on a pig at this time, the strong cold stimulation makes the sweat pores all over the pig's body contract sharply, the release of body heat is blocked, and the body temperature instead rises abruptly; in mild cases the pig develops a high fever and inflammation of the lungs, and in severe cases it

What to Do When Fish Eggs Grow Mold? Cause Analysis and Prevention Methods
[Prevention and Control] 1. Add a few drops of gentamicin or a few drops of malachite green solution into the hatching tank to effectively prevent the fish eggs from growing mold. 2. Use a pipette to promptly remove the whitened fish eggs to prevent the mold from spreading. 3. Improve the water quality of the hatching water, such as raising the water temperature or using circulating water filtration equipment, to shorten the fish egg hatching time and reduce the chance of mold infection.

Master the correct method when earthing up ginger to avoid damaging the roots
Ginger needs to be earthed up several times during its growth period. It is understood that the mechanical earthing-up machine used locally in Anqiu causes more serious root damage to ginger than manual earthing up, because the furrow bottom formed by the earthing-up machine is about 20 cm wide and the ridge height is 40 cm, while manual earthing up with a hoe leaves a furrow bottom of about 10 cm and a ridge height of around 35 cm. "When the earthing-up method cannot be changed, excessive root damage can be avoided by adjusting the growth direction of the underground ginger tubers, that is, when sowing the seed ginger, deliberately place the seed ginger perpendicular to the planting row, so that the daughter ginger and granddaughter ginger are also perpendicular to the planting row. By the time of earthing up, the entire ginger tuber is then perpendicular to the planting row, while the fleshy roots, lateral roots and fibrous roots caused by earthing up extend along the direction of the planting row, so they will not be damaged too much during earthing up. If the underground seed ginger is sown parallel to the planting row, too many roots will be damaged during earthing up." said Liu Shinian of Qianyulin, Linghe Town, Anqiu City.

What to do when eggplant seedlings grow leggy? Learn this traditional method to control it
Identify the "leggy" plants, count down from the top of the seedling stem, and at the internode below the third leaf, gently pinch with two fingers to make it give a "pop" and release water, so that the vascular tissue is temporarily damaged and cannot transport nutrients upward, causing the seedling to "sit" and stop growing. After 3-5 days, once the pinched wound heals into a "knob," normal growth resumes. At this point, the weak seedlings, small seedlings, weak branches and small branches around it that were not "pinched" are all growing, and most catch up with the original "leggy" seedlings that were "sat" into sturdy seedlings, making the vegetable seedlings across the whole garden grow uniformly, achieving high yield and quality.

How should cuttings be treated when propagating yew (Taxus) from cuttings?
When propagating yew from cuttings, the method for treating the cuttings is: cut branches at least 15 cm long as cuttings, remove the lower leaves, girdle the base of the branch to make a wound 0.5 to 1 cm wide, wait until nodular growth forms around the wound, then cut the branch off below the girdled part, and soak the basal end in 100 ppm indoleacetic acid or phenylacetic acid for 3 hours, or soak it in a 200 ppm ABT No. 2 rooting powder solution for 8 to 10 hours.

What to Do When Shell Mushrooms Appear? Detailed Explanation of Prevention and Control Methods
Due to excessively strong light, the fruiting bodies lose water rapidly and shell mushrooms are prone to develop: the stipe is short and thick, and the stipe cannot be seen from the outside; the cap is underdeveloped and shell-shaped in appearance, with no gills or only traces of gills, and the cap color turns darker and glossy. Prevention and control methods: add more covering material to the mushroom shed. Reduce ventilation, increase water spraying, and raise the relative air humidity in the mushroom shed.

What to do when mushrooms grow from the sides of the bag and many are deformed
During sterilization, the bags press against one another, the round bags become deformed, and gaps form between the substrate and the bag, providing air and space for the mycelium to knot together. Add low temperature, light stimulation and mechanical stimulation (such as turning the bags over), and the mycelium on the sides of the bag knots to form primordia, which develop into fruiting bodies. Because of the restriction of the plastic bag, these mushrooms are all deformed. When this happens, pinch and press the mushroom buds promptly to stop their growth, so as to avoid wasting more nutrients. The fruiting bodies are small and the marketable rate is low:

When is the most suitable time to harvest wine cap mushrooms?
The wine cap mushroom (Stropharia rugosoannulata) is larger than common edible mushrooms. A common edible mushroom weighs about 10 grams per cap, while a wine cap mushroom weighs around 60 grams, with the heaviest reaching up to 2500 grams, and a diameter of 5-40 cm. It should be harvested in a timely manner according to its maturity and market demand. From pinning, that is, the appearance of the white primordium, to maturity, the fruiting body takes about 5-10 days, varying with temperature. At low temperatures it grows slowly, but the mushroom body is thick and fleshy and the cap is not prone to opening. Conversely, at high temperatures it presents a small cap shape and opens easily. Throughout the entire growing period, 3 flushes can be harvested.

What technical principles should be followed when thinning flowers and fruit on pear trees?
Thinning flowers and fruit is, on the basis of winter pruning, the regulation of flowers and fruit on trees that still have too many flowers or have set too much fruit; this is a means of achieving a reasonable crop load; its main functions: first, to overcome biennial bearing and stabilize both yield and tree vigor; second, to ensure that the current year's fruit is large and uniform, so that every fruit left on the tree develops into a qualified, high-quality marketable fruit and few culls are produced; third, to form a sufficient number of flower buds for the following year's crop and maintain strong vigor. Trees that are not thinned or that carry an excessive fruit load very easily develop biennial bearing. The essence of biennial bearing is that the fruit

Which six diseases should be prevented when keeping dogs in spring?
Spring is a period of high incidence for various dog diseases. Therefore, it is very important to do a good job in the prevention and treatment of dog diseases in spring. Specifically, the prevention and treatment of the following six diseases should be carried out well. 1. Rabies Rabies, commonly known as mad dog disease and hydrophobia, is an acute, contact zoonotic disease caused by rabies virus, mainly invading the central nervous system. Preventive measures: The principle of prevention is mainly to do a good job in "prevention, inspection, elimination, and treatment." 1. Prevention: Make sure vaccination is done well. Dilute each bottle of vaccine with 10 ml of sterile water. After fully dissolving, inject 1 ml subcutaneously or intramuscularly into each dog.
