Cutting time of sweet leaf chrysanthemum
There are spring and autumn insertions in cuttings. The spring cut time is from March 20 to the end of April, and the time of autumn insertion is from early September to before the beginning of winter. Generally, large areas are used in autumn.
Sweet chrysanthemum cutting seedbed selection
Generally, sandy loam land with flat land, fertile soil, and convenient discharge irrigation. After digging over the pre -prepared seedbed, the first finishing is made, and then covered with the ground membrane. The purpose is to destroy the pests buried underground to avoid the evaporation of moisture to keep the surface moisture.
Sweet chrysanthemum cutting method
On the precisely sorted seedbed in advance, two sides of the seedbed are fixed with two thin ropes on both sides of the bed, and a small mouth is cut with a knife, and the prepared signs are inserted. In the middle, it is best to keep the distance between the seedlings of 3.5cm and the plant spacing of 1.2cm. After inserting it, pour the multi -bacterial spirit and pour it through the water. If it is sunny, cover the shade net before eight o’clock.
Sweet chrysanthemum cutting management
The first is to replenish water in time. The first few days after cutting is easy to wither, it is necessary to water it.
The second is to spray drugs to prevent diseases. After the first spray, it must be sprayed with a bactericide every two or three days. Once the sick plants are found, they must be pulled out immediately to avoid spreading.
The third is to cover up. Generally speaking, when the highest temperature during the day is 15-28 ° C, there is no need to unveil the shade net before the seedlings are inserted. From the fifth day, the lighting time is gradually increased. When the temperature is relatively high, it is necessary to cover the shade net, and it is only necessary to remove the shade net at around 5 or 6 pm. After that, the shading time is gradually shortened. You can take root in about ten days after inserting the seedlings, and you don’t need to shade after rooting.
Sweet chrysanthemum overwinter management
During the winter, sweet leaf chrysanthemums should take anti -freezing measures on the surviving plant seedlings. When the temperature is lower than 15 ° C, the film should be covered to keep the film insulation. If you are unfortunately encountering the cold current, cover the grass curtain at night to prevent frostbite. It is necessary to use a sunny day to rose to weed to replenish moisture and fertilizer. Note that when inserting seedlings in spring, in order to prevent the temperature from being low, the film must also be covered to improve the survival rate of the plant.
