What are the main diseases of Coprinus comatus? What is the method of pollution-free prevention and control?

Coprinus comatus, known as Maotou Ghost Umbrella, is a large fungus. Mushroom has delicate meat, delicious taste and rich nutrition, and has a variety of medicinal functions. It can be cultivated with crop straw, cottonseed hull, sawdust and other edible fungi waste. It is easy to cultivate and has high yield, so it can be used as a new project in industrialization. It is very suitable to be popularized in the adjustment of rural industrial structure. In the specific planting process, what are the main diseases of Coprinus comatus? What is the method of pollution-free prevention and control?

1. Planting time of Coprinus comatus

Coprinus comatus is a kind of straw rot dung native bacteria with strong adaptability, which belongs to constant temperature and medium temperature mushroom. The suitable temperature for mycelial growth is 23-28 ℃, and the suitable temperature for fruiting body is 15-18 ℃. It can be cultivated in spring and autumn, generally from June to August, from late September to December, and from November to February in spring. The cultivated species need to be heated properly and mushroom can be produced from April to June.

Second, what are the main diseases of Coprinus comatus?

1. Chicken claw fungus

This kind of fungus is a kind of serious parasitic pathogenic fungus, which mainly occurs in the period of self-body formation and growth, because its fruiting body is like chicken feet and is named Chicken claw fungus. In the process of mycelial growth of Coprinus comatus, it is disturbed by the pathogenic hyphae in the soil, and the two combine and grow to produce Pleurotus ostreatus.

2. Brown spot

Brown spot is mainly harmful to Coprinus comatus, and the surface tissue of autophagosomes will not go deep into Daojun's meat. when the disease occurs, brown spots will appear on the cap or stalk of the fruiting body, and with the continuous development and expansion of the disease, the whole fruiting body turns brown.

3. Rot disease

Rot is a common bacterial disease, which mainly harms the posture of Coprinus comatus. At this time, the posture of the disease turns brown at the initial stage of body formation, which leads to the black and rotten cover, leaving only the stalk. In the environment of high temperature, high humidity and poor ventilation, the incidence of the disease is relatively high, and in summer, because it is out-of-season cultivation, it is also easy to be infected with the disease.

Third, what is the pollution-free control method of Coprinus comatus?

1. Agricultural prevention and control methods

The first is to create a suitable fertility environment. During the period of mushroom production, we should pay attention to control the temperature and air humidity of the mushroom production site, ensure that the mushroom production site has good ventilation conditions, and avoid diseases caused by high temperature and humidity. At the same time, properly spraying nutrients (such as Enfei, Pleurotus ostreatus, etc.) to improve the disease resistance of Coprinus comatus mycelium; timely clean up mushroom root and dead mushroom, rotten mushroom, diseased mushroom to avoid the occurrence of infectious diseases. The second is rotation planting. Rotation planting with local crops requires a rotation of crops every two or three years to avoid repeated cropping.

2. Physical prevention and control methods

One is the protection of facilities. The ventilation is closed with an anti-insect net to reduce the occurrence of diseases and insect pests. The second is to set up insecticidal lamps to trap and kill pests, such as frequency vibrating insecticidal lamps, black lights and double-wave lamps.

3. Chemical control methods.

Coprinus comatus has been harvested edible fungi for many times in succession. In order to ensure that the products are safe and pollution-free, the following requirements should be followed when applying pesticides: first, in strict accordance with the safe interval, concentration and application method, they should be harvested first and then applied; second, 7 days before harvest, the use of chemical insecticides is strictly prohibited; third, alternate use of pesticides should be used alternately as far as possible to control diseases and insect pests. At the same time, the use of chemical pesticides must meet the production standards of pollution-free agricultural products. According to the growth of Coprinus comatus and the occurrence of diseases and insect pests, pesticides should be used reasonably and safely in order to achieve the effect of control.
