Reasonable selection of Scientific Formula of Pleurotus ostreatus
Pleurotus ostreatus has low requirements for raw materials, and many industrial and agricultural scraps can be used as raw materials. However, whether the ratio of carbon to nitrogen in the culture material is scientific and whether the addition of other excipients is reasonable is a problem that can not be ignored in the production of Pleurotus ostreatus. At present, the bag cultivation of Pleurotus ostreatus mainly uses cotton seed shell as raw material, so the quality of cotton seed shell is directly related to the yield of Pleurotus ostreatus and even whether it can be cultivated successfully. To choose fresh and high-quality cottonseed shell, if you choose moldy and deteriorated cottonseed shell, it will cause miscellaneous bacteria pollution, and even cause cultivation failure. Pesticides or other chemicals should not be added to the culture material.

Propagation of Taxus mairei
Choose a suitable nursery to choose fertile, loose, neutral or slightly acidic soil with good drainage, preferably in woodland or semi-shaded fertile land. Apply enough base fertilizer, rake flat, and prepare the bed for planting. The seeds matured in October and were harvested in time and placed in the mixture of water and fine sand (water / sand ratio 2 ∶ 1). Rub the seeds on the washboard, remove the seed coat, and wear the hard meat seed coat. The dry land without stagnant water and digging pits were selected and stored in the pits mixed with wet river sand at the ratio of 1 ∶ 2. In March of the following year, take out the net seed and use 50 degree liquor and 40% liquor.

Effect of different ratio of fertilization on yield of Rice
The premature senescence of rice from heading to maturity will lead to poor grain filling, increase of blighted grain and decrease of yield. There are many factors leading to premature senescence in the later stage of rice growth. First, improper cultivation and management. The planting density is too high, the plant growth is weak; the early and middle stages of nitrogen fertilizer application, phosphorus and potassium fertilizer and trace element fertilizer application.

Abnormal phenomena and treatment measures in the cultivation of Pleurotus ostreatus in late spring and early summer
Late spring and early summer is a good season for cultivating Pleurotus ostreatus. However, due to improper operation, some mushroom farmers caused abnormal phenomena such as yellowing and necrosis after mushroom emergence, sour and smelly culture material, delayed emergence of mushrooms after mycelium grew full bag, which decreased the success rate, yield and quality, and directly affected the economic benefits. Based on years of production practice and mass experience, the author summarizes the causes of abnormal phenomena and treatment measures as follows. 1. After the mushroom bag comes out, a large number of small mushrooms die in late spring and early summer. Sometimes after the mushroom sticks produce mushrooms, a large number of small mushrooms turn yellow and soft, the base becomes thicker, and then wither and rot.
