Off-season cultivation of edible fungi is highly profitable, with broad market prospects
So-called off-season cultivation refers to cultivation carried out in seasons when normal growth is not possible. In edible fungi production, this is essentially a matter of timing, that is, cultivation carried out in natural seasons when normal production is not possible through improved facilities and equipment, artificial regulation of conditions and other auxiliary means, and it can also achieve production results similar to those of normal-season production; for example, the relatively typical summer cultivation of enoki mushroom (Flammulina velutipes) and winter cultivation of straw mushroom, and so on. For example, the low-temperature variety enoki mushroom should fruit from November to February, but with facility-based automatic controlled cultivation

Green copper emulsion is highly effective against rice bacterial leaf streak
In an average epidemic year, the control efficacy reaches 85-91%, which is 10-15 percentage points higher than that of Japanese-made chlorothalonil. Method of use: in an average epidemic year, spraying twice is sufficient. The first spray is applied at stages 2-4 of young panicle differentiation in rice; 7 days after treatment the disease tends to stabilize, new acute lesions decrease significantly, and the original lesions stop developing after turning yellow. The second spray is applied 10 days later, using 100 mL of 12% green copper emulsion per mu each time, diluted 500-600 times for spraying. After 20 days, the rice leaf color turns noticeably greener, and the newly emerged flag leaf and the second leaf from the top have no

Poisonous mushrooms are highly dangerous; be on guard against picking and eating them in the wild
In forests, in grassy areas, and beside piles of manure and straw, people often see wild mushrooms pushing up through the ground. Because many people do not know the difference between poisonous and non-poisonous mushrooms, they sometimes pick poisonous mushrooms and take them home to eat. Cases of accidentally eating poisonous mushrooms occur from time to time, and there have even been deaths. For this reason, the relevant authorities remind the public not to blindly pick and eat wild mushrooms, so as to ensure food safety. Recently it has also been found that some farmers' markets are selling poisonous mushrooms. Wild mushrooms that you do not recognize and have never eaten must absolutely not be easily bought and eaten.

Pig eczema is highly prevalent in summer, and farmers must take strict precautions
Pig eczema, also known as pig damp-toxin disease, is mainly caused by pigs living in a damp environment for a long time. It is generally most severe during the high-temperature seasons of summer and autumn. Symptoms: affected pigs mostly develop the disease suddenly; at the beginning, the skin under the jaw, on the abdomen and on both sides of the perineum turns red, with broad bean-sized nodules appearing, and the pigs are restless due to itching. As the condition worsens, blisters and papules appear, and after they rupture they are often accompanied by yellow exudate, scabs and scales. If acute cases are not treated in time, they often become chronic, with the pig's skin becoming thick and rough and itching, and the pigs often rub against walls or trees to relieve the itching, leading to loss of hair over the whole body.

A Highly Effective Method of Using Mirabilite to Treat Pig Eczema
Eczema is a skin disease that occurs frequently in pigs in autumn. Acute and chronic eczema has the main symptoms of erythema, papules, and itching on the skin, and a few cases are accompanied by pustules, exudate, erosion, and scabbing, and it is especially harmful to suckling piglets. Based on practical experience in production, treatment with mirabilite has a highly effective result. Method: according to the size of the pig and the area of the affected part, take 50-200 grams of mirabilite respectively, add 200-500 milliliters of cold boiled water, and after dissolving, apply and rub the affected part, 4-5 times a day, or use a clean towel to dip the liquid and wipe the affected area, for half an hour each day,

Sheep nasal bot fly disease is highly harmful; how should it be prevented and treated?
Sheep nasal bot fly disease is a parasitic disease caused by the bot fly parasitizing the nasal cavity and cranial sinuses of sheep. In recent years, among the flocks raised by farmers in our region, because insufficient attention was paid to the prevention and treatment of bot fly disease, the infection rate of sheep nasal bot fly disease rose sharply, affecting the normal growth and development of sheep and seriously affecting the fattening results of sheep. Through in-depth systematic investigation and study of sheep nasal bot fly disease among farmers and farms, and observation of prevention and treatment, the author achieved relatively good results, now reported as follows: 1. Pathogen

Why is the new cotton line Zhongchang-03 so highly favored?
On an autumn day, although the sky was drizzling and there was a Force 3-4 north wind, it did not dampen the enthusiasm of more than 40 representatives from all over the province who came to Changxinpu Village, Diaodong Cotton Original Seed Farm in Hanchuan City, to observe and inspect the new cotton line Zhongchang-03 on site. Although the representatives' shoes and trouser legs were covered in mud, when they saw the cotton plants loaded with 30-40 large, round bolls, they came into the field excitedly, counting and looking and bustling nonstop. One representative counted nearly 100 bolls on a single cotton plant and was tempted to pull it up by the roots. Kuang Dongping, general manager of the Yangtze River Company of China Cotton Seed Industry under the Cotton Research Institute of the Chinese Academy of Agricultural Sciences,

Foliar feeding of cotton at the late stage is highly effective, and growers should pay attention to it
In the late growth stage of cotton, the root system's ability to absorb nutrients declines markedly. At this time, spraying foliar fertilizer to supplement nutrition has the effects of preventing premature senescence, preventing diseases, promoting large bolls, promoting early maturity and pursuing high quality, with remarkable effects in increasing yield and income. 1. Spray nitrogen fertilizer to prevent premature senescence: In the late stage of cotton, foliar spraying of nitrogen nutrition can keep cotton leaves green, enhance photosynthesis, and prevent nitrogen-loss premature senescence. Mixing nitrogen fertilizer with "regulator 802" makes the effect of enhancing cotton's late growth vigor more obvious and the yield-increasing effect better. From late August to early September

Success in Extracting Highly Effective Anti-Cancer Substance from Cloned Yew
Sichuan University professor demonstrates unique plant transgenic cloning technology, with the next step focused on anti-cancer plants. "We have already used transgenic cloning technology to successfully clone two plants with different genes, and the next step is to apply this technology to cloning the anti-cancer drug paclitaxel." Recently, Professor Wang Li from the Plant Research Laboratory of the College of Life Sciences at Sichuan University showed reporters a transgenic cloning technology little known to outsiders. A plant cloned from a leaf. In the laboratory, Professor Wang pointed to a green plant about 20 cm tall and said: "

What are the highly effective pesticides for controlling rice skipper?
1. Optimal control period: This should be strictly timed to the peak egg-hatching stage and young larval stage of the rice skipper in the field, that is, July 29 to August 6 is the best period for pesticide application. 2. Targets for control: Rice fields with tender green growth, late transplanting and late development, late development after sitting, and seed-production maternal rice fields are all key target fields for control. 3. Protect natural enemy resources, prohibit the application of highly toxic pesticides, increase the parasitism rate of eggs, larvae, and pupae, and achieve pest control through beneficial organisms. 4. Chemical control: For rice skipper, use Qiansheng 8000 at 50 grams per mu, 90%
