Generally, bluegrass should be potted once every 2-3 years, from March to April every year, or in the middle of10-1. When dividing the pots, the soil in the pots should be dry. If it is wet mud, it is inconvenient to operate, and it is easy to break roots and get injured. After the mother plant is turned out, gently remove the soil, wipe it according to the natural plant, trim the broken roots and residual leaves, and be careful not to touch the leaf buds and fleshy roots. Then wash the roots with clear water and put them in the shade. When the roots turn white and dry, they can be split into pots. If the weather is getting wetter and wetter, the bluegrass must be exposed to the sun for about 10 minutes, which is beneficial to the growth of bluegrass.
2. Soil selection of bluegrass cultivation methods.
When planting bluegrass, it is best to use slightly acidic soil, and it is best to use earthenware pots or Yixing earthenware pots for planting flowerpots, which is beneficial for the aerial roots of bluegrass to breathe in plant flowerpots. When planting, it is necessary to cover the hole at the bottom of the basin with mussels and brown slices. , and thicken sand, cinder and charcoal into steamed bread, accounting for about 1/3 of the capacity. Add culture soil about 3-5 cm thick. Then put the bluegrass into the pot, densely arrange the roots, add the mixed fine soil until it is 2~3 cm away from the pot, and lift the bluegrass slightly. The height should be based on the level of the upper end of the pseudobulb and the soil surface, not too shallow or too deep.
3. Cultivation methods of aquatic plants
It is very important to water bluegrass reasonably when planting. When watering, water bluegrass with clean and slightly acidic water. When watering, you should look at different plants. 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 are watered once, you should see that the soil in the basin is dry and the plants turn white by about one centimeter. In the breeding period, in order to improve the air humidity of bluegrass, we can add water from the rich potted materials on the basin surface to keep bluegrass and pseudobulb moist. When the whole basin is not dry enough, water it again and thoroughly.
4. Fertilization of Poa pratensis cultivation methods
In order to better promote the growth of Poa pratensis, fertilization is very important. When fertilizing it, you can use organic fertilizer. Organic fertilizer, that is, farmyard manure, should be thin and can be applied once every ten days. If other inorganic fertilizers are used, they need to be used according to their instructions. Lamian Noodles grass can be topdressing foliar fertilizer in the growing period. When turning over pots and changing soil, its base fertilizer is very important, but the fertilizer can't touch the roots of bluegrass. You can add a proper amount of base fertilizer to the soil. If there is too much fertilizer, it will burn the roots of bluegrass and produce black spots. If it is properly fertilized, it will grow strong seedlings and flowers. When applying fertilizer to Poa pratensis, it is required that the amount is small, clear and light, and the principle of thin fertilizer and diligent application is achieved.
5. Matters needing attention in cultivation methods of Poa pratensis
When the pot soil of bluegrass is dry and the watering time is prolonged, the tip of bluegrass is often burnt. This phenomenon is also a signal to water, but it is too late, because the leaves of blue grass are hurt by sharbat, which is incurable.
When it is not early in summer and spring, the climate is relatively dry, so you must water more when watering, water more when it is dry after autumn, and water less when it is rainy in summer. Be sure to water more on days with strong hot air and less on days with frequent wet winds.
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.
