Use of planting materials. According to the experience of cultivation in various places, orchids can grow well no matter what plant materials (including soilless culture) are slightly acidic. The problem is that different plant materials should adopt different management methods. It is best to use pottery pots or Yixing pottery pots for flowerpots, because orchids are aerial rooting plants, and the ventilation of flowerpots is very beneficial to the growth of orchids.

Rational watering is the key to raising orchids. The water for watering orchids should be clean and slightly acidic, and never water sewage with germs. The method of watering varies from plant to plant. Loose mountain mud contains enough water, and granular soil and rocky volcanic rocks absorb enough water, but there is no water accumulation; After different plants were watered once, the surface of the basin was dry and the plants turned white by about one centimeter. In order to raise the temperature, water can be sprayed on the surface of the pot to increase the water content of the planting materials in the upper abundant pot, so that the bluegrass and the pseudobulbous roots can be kept moist to a certain extent, and then the whole pot can be watered before it is completely dried.

Fertilization of Poa pratensis On the basis of mastering watering, fertilization becomes more and more important in order to promote the better growth of Poa pratensis. Organic fertilizer, that is, farm manure, should be diluted every ten days, and other inorganic fertilizers (fertilizers) should be used according to the instructions. Foliage fertilizer can be topdressing outside the roots during the growth period of orchids. Base fertilizer is also very important. When turning over the pots and changing the soil, a proper amount of base fertilizer can be added without touching the orchid roots. Too much fertilizer can easily burn orchid roots and produce black spots. If fertilized properly, it can grow strong seedlings and flowers. Orchid fertilization is generally required to be small, thin and light, and it is really thin and diligent.

Insect diseases are easy to prevent, but fungal diseases are difficult to treat. If pests such as scale insects are found in bluegrass, they can be sprayed according to the instructions, and it is best to use them together, 2~4 times a year. General bacterial diseases can also be treated as black spots. According to the instructions, fungicides such as chlorhexidine, methyl butyl mustard and chlorothalonil can be used. During the growth period of 15~20 days, regular cross treatment and preventive spraying can be carried out. If Balasi soft rot (rotten coccidiosis) is found, it is an incurable disease of orchids. Once found, it can be removed in time. Therefore, when buying bluegrass, we must pay attention to the fact that we must buy diseased grass with lower price at home, which will affect other valuable bluegrass.
