The production of rhododendron for greening is the direction, don't use wild piles.
In view of the phenomenon that some seedling growers use wild cuckoos as rootstocks for engineering modeling cuckoos, Li Yong, secretary general of the cuckoo branch of the China Flower Association, said recently: modeling is an effective way to increase the added value of cuckoos for greening, but the use of wild piles for grafting is not recommended. It is understood that although there are not many nurseries mainly for planting cuckoos for greening projects in China, annual supply has been achieved in many places in the south. Therefore, without being affected by the disaster, the cuckoos used for greening in China are basically saturated.

What to do when shell mushrooms appear?
Because the light is too strong. As a result, the water dispersion of the fruiting body is prone to the occurrence of Pleurotus ostreatus, the stalk is short and thick, the stalk can not be seen from the outside, the cap is underdeveloped, the shape is like a shell, there is no bacterial fold or only the trace of bacterial fold, and the color of the cover turns dark and shiny. Control method: increase the mulch in the mushroom shed. Reduce the amount of ventilation, increase the amount of spraying water, and improve the air relative humidity of the mushroom shed.

How to identify poisonous wild mushrooms (bacteria)
So far, more than 10,000 species of wild mushrooms have been found and recorded in China, including 192 species of poisonous mushrooms and more than 30 species of poisonous mushrooms in Jiangsu and Zhejiang provinces. Wild mushrooms (bacteria) generally grow in the plum rain season and high temperature and humidity climate in summer and autumn, so food poisoning events also occur in this period. Poisonous wild mushrooms (bacteria) often have the following characteristics: (1) high color and lustre. (2) the surface of umbrella-shaped mushroom (bacteria) is fish scale. (3) there are annular protuberances on the mushroom stalk. (4) Mushroom

Control Measures of Mushroom Shed Disease Pests
With the development of vegetable basket project, the demand of edible fungi increased correspondingly, but pests in mushroom shed caused great obstacles to the development of edible fungi. In order to alleviate this contradiction, the main pests in mushroom shed and their control methods are introduced. 1. Mushroom fly larvae, also known as maggots, mainly feed on fruiting bodies to cause tunnels and affect quality, and the wounds caused are also easily infected by germs and rotted. Different methods should be adopted to control mushroom flies at different stages. A large number of maggots occur in front of this mushroom, and dichlorvos can be used according to 0.90 kg/

How can Pleurotus ostreatus cover soil be high-yielding?
After the Jinfu mushroom strain is full, it can be buried in the soil in 5 days. The strain bag is about 10 cm wide or has a cross section of about 10 cm. The buried soil is 8 cm deep, and the bag is placed horizontally, opposite to each other, 5 cm apart between the bags, 4 in a row, 40 in a group, and then covered with soil. Cover the bag 3 cm, the soil should be granular, not easy to be too fine, the day before the soil cover, it is best to adjust the soil to semi-dry and semi-wet. The moisture of the soil should be adjusted for two days, and all the soil should be moistened, and the water should be carried out under the aerated condition of the mushroom room. Don't spray door water. Cover soil to transfer water
