How to do a good job of disinfection and sterilization treatment for edible mushroom greenhouses
In edible mushroom cultivation, the most important thing to pay attention to is the problem of disease and pest control, and the essence of the problem, in the final analysis, is actually a matter of prevention. Therefore, in the entire production process of edible mushrooms, always adhering to the principle of "prevention first" is very necessary for every producer. Through hotline consultation content, combined with the actual situation of surveys, the author found that quite a few mushroom farmer friends are very vague about the disinfection (sterilization) and killing (bacteria) treatment of mushroom greenhouses, or even indifferent to it. Some, although already somewhat aware, have treatment measures that

What to Do About Leaf Drop in Golden Privet During the Growing Season? Causes and Control Measures
In 1999, golden privet (Ligustrum × vicaryi) began to be trial-planted in the Hengshui area of Hebei, and the planted area then increased rapidly. However, starting in 2002, a small number of local golden privets began to drop leaves during the growing season, showing patchy bare spots, and the problem kept spreading. By mid-June 2003, spots appeared successively on the leaves of golden privet over a large area; the spots appeared on old leaves later than on young leaves, then progressed to drying up, leaf drop, and the branches gradually dried up from top to bottom, with a small number dying. The dead patchy areas were mostly in the middle of the planting site.

Why don't silkworms spin cocoons? An analysis of common causes
1. Pathological factors. For example, flacherie and soft rot are prone to infecting and causing disease before mounting, destroying the silkworm's silk gland secretion function, or the pathogen produces large amounts of toxic metabolites in the silkworm's body, paralyzing the silkworm's nerves so that it cannot spin silk and form a cocoon; 2. Physiological factors. First, abnormalities of the middle silk gland, mainly caused by rearing temperatures that are too high or too low, leaves that are too tender, or imbalance of the secretory glands, which causes silk gland abnormalities and prevents spinning; second, abnormalities of the anterior silk gland, mainly caused by exposure during rearing to excessive coal gas, fishy odors, alcohol and other harmful gases

Calcium and phosphorus metabolism disorders in geese caused by vitamin D deficiency
Vitamin D (VD) deficiency, calcium or phosphorus deficiency, and an imbalance in the calcium-to-phosphorus ratio can all cause osteoporosis, resulting in rickets in young geese or osteomalacia in adult geese. This disease is a nutritional bone disease that can occur in geese of different ages, and clinically it is often seen in young geese 1-3 weeks of age. The main signs are stunted growth and development, skeletal deformities, limb weakness, weak legs, and even paralysis. When adult geese are affected, egg production decreases or soft-shelled eggs are laid. In addition, this disease can also trigger other diseases, often causing certain economic losses to the goose-raising industry. 1. Dise

Research progress on the mechanisms by which porcine circovirus type 2 infection causes immunosuppression
Circovirus infection is a newly discovered infectious disease. The disease has a relatively high infection rate in pigs and occurs widely throughout the world, having become one of the infectious diseases that seriously affect the development of the pig industry. Circovirus mainly attacks the pig immune system, interfering with and destroying the body's production and maintenance of immune antibodies against disease, resulting in reduced resistance and making pigs susceptible to secondary or concurrent other diseases. In recent years, scholars at home and abroad have conducted a great deal of research on the mechanisms by which porcine circovirus invades the immune system, and certain progress has been made in the virus replication mechanism, its effects on cytokines and lymph

Many Methods for Propagating Goji Berry: A Full Analysis of Commonly Used Propagation Techniques
1. Seed propagation: Spring sowing should be carried out from late March to mid-May, when temperatures rise noticeably. Soak the seeds in 30°C warm water for 24 hours, then rub them, pick out the flesh and skin, take out the sunken seeds, and dry them. Mix the seeds with wet sand at 1:3, then place them indoors at about 20°C to germinate, keeping them moist. When about 30% of the seeds have cracked and shown white, germination is complete. For the nursery site, loam or sandy loam near a water source can be chosen as the seedbed. It requires flat terrain, good drainage, and ample sunlight. Apply 5000 kg of decomposed barnyard manure per mu

Main Problems and Cause Analysis in Pleurotus pulmonarius Cultivation
At present, the cultivation area of Pleurotus pulmonarius in our city has exceeded 50 million bags, making it one of the main edible mushroom varieties cultivated in our city, with good cultivation prospects and benefits. Pleurotus pulmonarius cultivation can be carried out year-round through low-temperature treatment in cold storage. However, due to improper season, variety, culture medium, temperature treatment and water control, phenomena such as failure to fruit or death of mushroom buds often occur. Through years of cultivation practice, we have explored and summarized the above problems for the reference of peers. 1 Variety selection Currently, the main variety cultivated in our city is the Pleurotus pulmonarius series introduced from Taiwan, China by Luoyuan
