1, short-cut pruning
If asparagus stems are too long, they can be trimmed properly. Prepare a sterilized sharp knife, cut off the long branches and cut off some long branches.
2. Selection and control of water and fertilizer
Water and fertilizer should be controlled when asparagus is still a seedling. Newly planted asparagus can be properly fertilized. When it is stable, it is necessary to control fertilizer and water in the spring and summer growing season, and the fertilizer solution can be used once a month, and the amount of fertilization should not be too large. We should master the principle of thinness. There is also water control. The water must be dried before watering. The water must be dry to the degree of separation of basin and soil, and the water control should be moderate. Therefore, foliar spraying should be strengthened during the water control period.
Recommended plastic methods for asparagus:
1, Tower: Choose 2~3 tall and beautiful stems as the main peaks, remove all the growing points on the stems, and set the height to 30-35cm. The remaining branches and new stems should not be higher than the main peak. For new shoots, the growing point can be determined according to the thickness of their stems. If its stem is thicker than the main peak, it should be picked; If it is thinner than the main peak, there is no need to pick it and let it grow. At the same time, it is necessary to constantly adjust the plant morphology by using the object occlusion method and its own phototaxis.
2. Double-cluster type: plant two asparagus plants, one high and one low, with a height of about 30 cm and a minimum of about 18 cm, and then grow into a tower asparagus.
3. Natural style: The plant type of asparagus grows naturally, and the basic methods such as picking growing points, covering things and using its phototaxis are still used to stretch branches and leaves, giving people a natural aesthetic feeling.
