Prevention and treatment of common diseases of Pleurotus ostreatus
In cloudy days, lack of light and high relative humidity in the mushroom shed, Pleurotus ostreatus is extremely prone to two complications: soft rot and bacterial spot disease. So how can we prevent and cure this complication? according to our practical experience, we specially introduce the following comprehensive prevention and control methods to mushroom farmers. 1. Breeding disease-resistant varieties and cultivating strong hyphae to improve the disease resistance of Pleurotus ostreatus. Such as: Hebei without spores, Jiangsu wild wind, etc., the mycelium growth is snow-white, the fruiting body has strong disease resistance and high yield. 2. Increase ventilation and purify the air environment. 3. Use sewers to replenish water

What if Pleurotus ostreatus grows green mold?
Recently, Li Zhibao, a grower of Pleurotus ostreatus in Zhumiao Village, Nancheng Town, Xiajin County, Shandong Province, called to consult: the market of Pleurotus ostreatus is good this year, with a wholesale price of 1.50 yuan / jin. He suddenly invested 20000 jin of materials to cultivate Pleurotus ostreatus, but now there are some green things growing on Pleurotus ostreatus cultivation bags. Experienced people say it's green mold. I don't know what to do. The author's reply is as follows: green mold is the main disease in the cultivation of edible fungi, which mainly occurs on the fungus mass without bacteria or the culture material without thorough disinfection. It is easy to breed green mold in the environment with high acidity and humidity. Its spores spread in the air.

The reason for the poor growth of Pleurotus ostreatus
Some Pleurotus ostreatus growers write to say that their Pleurotus ostreatus is not growing well and want to know what the problem is. Here are some analysis and reminders on some problems often seen in cultivation: the first reason may be that the ambient temperature and material temperature are not right. If the temperature range of mushroom production is higher or lower than that of the cultivated varieties, there will be no mushroom emergence or the phenomenon that the mushroom will no longer produce normally after a tide of mushroom turning to tide. The second reason is the poor ventilation of the mushroom shed. Poor oxygen supply and high carbon dioxide concentration are not conducive to mushroom production, and will increase when severe hypoxia occurs.

Discussion on cultivation techniques of Cotton at Seedling stage
Cotton is grown in more than 100 countries in the world. Asia is the largest cotton producing continent in the world, accounting for 70% of the world's output. China is the largest cotton producer in the world. In recent years, the annual cotton planting area is generally stable at more than 75 million mu, with a total lint output of more than 6.5 million tons. Hubei Province is one of the seven major cotton producing areas in Dian, with a perennial cotton planting area of about 7 million mu and a total lint output of about 500000 tons. Huangmei has a perennial cotton planting area of about 210000 mu. The total output of lint is about 23000 tons, and the planting area and output are among the top 10 in the province.

Control of cotton seedling diseases in spring
In recent years, due to the low temperature in spring, direct seeding cotton seedling diseases occurred seriously, resulting in a large number of dead cotton seedlings. In order to improve the economic benefit of cotton farmers and reduce the losses caused by diseases, several diseases symptoms and control methods of cotton seedling are introduced as follows: 1. Symptoms of cotton seedling damage 1. Anthracnose: Both leaves and stems can be affected. After the seedlings were damaged, reddish brown fusiform stripes appeared at the base of the stem, longitudinal cracks, and serious disease spots expanded brown, black, and rotten, resulting in the death of seedlings. When the weather is wet, the spots produce an orange sticky substance

Control measures of Cotton Seedling Diseases in Binzhou City
There are many kinds of diseases in cotton seedling stage. The most serious diseases in cotton seedling stage in our city are blight, anthracnose and red rot. In recent years, especially the first two diseases are more serious than in previous years. Doing a good job in the prevention and control of cotton seedling diseases is the key to the increase of cotton production and income in our city. At present, the key to the prevention and control of cotton seedling diseases is to implement the plant protection policy of "prevention first, comprehensive control". 1 symptoms of cotton seedling disease 1.1 the obvious symptom of blight in the field is the growth of cotton seedling root and near-ground stem base.

Experience in High-yield cultivation of Cotton
First, before sowing, you should first buy improved cotton seeds, advocate changing cotton seeds every year, and never be cheap, and use second-or third-generation cotton seeds, because the output of self-retained seeds will be reduced by about 10% every year. Use about 1.5 kilograms of seeds per mu, dry the seeds before sowing, the cumulative drying time is not less than 30 hours, and constantly turn over. Be careful not to spread it directly on the cement floor, brick floor or metal plate. Before sowing, the soil moisture must be made and preserved in time so that the soil moisture can be planted. Second, scientific fertilization and adequate base fertilizer, generally applying high-quality farm manure per mu.

Cotton tubule at high yield seedling stage
Cotton seedling management is very important, which is directly related to whether cotton can build a good shelf for high yield and adjust the reasonable transformation from vegetative growth to reproductive growth. Seedling management principles are: first grasp the whole seedling, on this basis to cultivate strong seedlings, promote early seedling. Seedling management points are: timely check seedlings after sowing, found rotten buds, rotten seeds, should be timely replanting. Thinning and fixing seedlings can be carried out twice. After the first time, keep strong seedlings, pull out weak seedlings and sick seedlings. The second time was carried out at 1~2 true leaves, and the seedlings were fixed at the three-leaf stage, when the stem base had lignified and the resistance was
