Achilles conservation methods
Zip
Cuts out the twigs of the fresh chrysanthemum branch. In the wuhan region, interpolation time is usually around may. The piping matrix can be used in yellow sand, pearl rock or peat soil and sprayed against the matrix and the injection with microbicides such as enzymes and polybice。
I'm a little girl
The first week after the incubation can be filled with more water, which can be gradually reduced to ensure that the chrysanthemum is not abated. It would be preferable to have proper shades to reduce water evaporation. After two to three weeks, the root of the stem can produce a fine new root。
Soil
Arsenals are subject to the choice of border soil rich in decomposed, loosely fertilized, well-drained, sandy soil, with the soil being less acid-neutral. A new soil is needed every year for the chrysanthemum。
Go, change
The upper chrysanthemum is planted in a 12cm calibre, 12 cm high or small plastic basin at a stubble length of about 3 cm。
Let's go
The roots of the basin are growing as pyres grow. How do you figure the right time for a change? At about 20 cm altitude, the pyrethroids are lifted with the soil, and the soil needs to be full enough to change the basin. It's 20 cm caliber and 15 cm altitude。
Water
The ash requires wet, timely and appropriate water。
Water the saplings
The amount of water used varies from plant to plant at different stages of growth. In may-june, the seedling phase at the beginning of the basin should be dryed to promote the growth of the root system. During the month of july-august, high temperatures and dry conditions were observed, and pyres grew to the medium term, with high water consumption and heavy water demand. Late in august and between september and october, temperatures were reduced, and water was needed for the growth and pregnancy of the asyreums. After the mid-term flowering in november, the pelvis is used to keep the flowering season longer, and water is usually poured around noon once a day. When watering, be careful not to splatter the mud to pollute the leaves and flowers, otherwise they will be ill and the flowers will rot。
Fertilizing
The use of urea, compound fertilizer, potassium dihydrophosphate and the nutrients available on the market are optional options for the pursuit of fatty, preferably alternately。
Fertilizers are mainly irrigated and the soil should be kept dry prior to fertilization. After two weeks in the upper basin, fertilization can begin (at concentrations of less than 2 per thousand), with the seeding period dominated by nitrogen fertilizer, with organic fluids, urea and composite fertilization rotating. During the summer seasons of high temperatures and heavy rainfall, conditions are in place to adequately cover the rains, which are not allowed to be fertilized at this stage and should be applied in an ad hoc manner. After the fall, the weather gradually cools and the fertilization concentration can increase gradually and be applied once a week. After the fall, fertilizer is applied mainly on the basis of potassium phosphorus fertilizer, mixed and organic fluid fertilizer is applied on a rotational basis and can be sprayed once a week with a 2-percent potassium phosphate solution in the form of leaf spray. The buds are colored, stop fertilizing. Fertilizer is used to wash leaves with water spray to avoid burns。

The heart is the top of the main branch or the side branch。
