1, environment selection

The choice of environment is more important. As long as we master the growth law of orchids and provide or create environmental conditions close to orchids, Cymbidium hybridum is suitable for planting all over the country.

2. Planting materials

The use of plant 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.

Second, the cultivation techniques

1, water:

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.

2, fertilization:

On the basis of mastering watering, fertilization becomes more and more important in order to promote the better growth of Kentucky Bluegrass. 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, during the growth period of 15 ~ 20 days, fungicides such as propargite, methylbenzene and chlorothalonil can be used for regular cross-treatment and preventive spraying.

Other preventive measures

Bluegrass is a light-loving plant, but it should also avoid strong light when it is illuminated, so it should be shaded according to its growth habits, and the shading amount can reach 70%.

Bluegrass is a light-loving plant, but it doesn't mean it doesn't need sunlight. If you grow in a dark place for a long time, the accumulation of organic matter is limited and cannot meet the needs of growth, which will affect the differentiation of flower buds, and naturally you will not spend or spend less in the coming year.

If pests such as scale insects are found in bluegrass, they can be sprayed by oxidizing fruits or killing enemies according to the instructions, and it is best to use them together, 2 ~ 4 times a year. During its growing period, it can be treated and sprayed regularly every 15-20 days. If the bluegrass planted at home has coccidiosis, it is urgent to remove it in time, because this disease is a terminal disease in bluegrass and can be cured without harm.
