1, pot control method: the size ratio of flowerpot to plant should be 1: 3, which can limit the growth of root system and keep the plant size unchanged.
2. Remove the growing point: When the new bud grows to 2-3 cm, remove the growing point, which can promote the regeneration of branches and leaves on the stem, control them not to grow vines, and make the branches and leaves flat and the plant shape full.
3. Using the phototaxis of asparagus: rotating the direction of flowerpot in time can correct the growth shape of branches and leaves and keep the plant type unchanged.
4. Object shading method: that is, press the branches and leaves with cardboard or shade the sun, so that when the branches and leaves grow, they will rotate or bend to shade when they meet objects, thus achieving the purpose of modeling.
5. Comprehensive application of several modeling methods:
(1) Tower: Choose 2-3 tall, straight and beautiful stems as the main peak, remove all the growing points on the stems, and set the height to 30-35 cm. 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-clump 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 shape them into tower asparagus in the growth process.
(3) Natural style: The natural growth of asparagus is the main plant type, and the basic methods such as picking growing points, covering things and using its phototaxis are still used to stretch the branches and leaves, giving people a natural aesthetic feeling.
It should be noted that the shaping of asparagus must be combined with fertilizer control and water control. That is, when the room temperature is 15- 18℃, water it once a week to keep the soil moist (it is advisable to press it with your fingers). Not fertilized or less fertilized.
