Asparagus leaves are beautiful, elegant and exquisite, and potted plants are often placed on bookshelves, desks and coffee tables to beautify the living room. However, due to its rapid growth, its small and beautiful appearance often cannot last long, and it must be remolded. Now the plastic methods are introduced as follows:
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, prevent vines from growing, and make the branches and leaves flat and 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.
The stem of asparagus is climbing. If it is allowed to grow, it will lose its lightness if it can reach several meters high. Measures to shorten asparagus are:
1. For seedlings, it is not allowed to apply more fertilizer in spring and summer when they grow vigorously, but only once a month. The amount of fertilization should not be too large, and the principle of light should be mastered. For old plants, it is best to apply little or no chemical fertilizer, just use the opportunity of changing pots to fill the bottom of pots with fresh soil or apply a little fertilizer. In this way, both young and old plants can maintain a stable growth potential.
2. Pay attention to frequent pruning. Asparagus grows fast, so it is necessary to trim the old branches and dry stems at any time and keep the posture of low bottom. At the same time, cut off the trailing branches in time to keep them tall, beautiful and lush and green.
3. Selection of dwarf asparagus varieties. Short asparagus stems have no tendrils and can be kept small and exquisite.
4. Using chemical dwarfing method. When the new seedlings grow to the height of 100cm, spraying paclobutrazol diluted by 1000 times can effectively control their growth height and increase their ornamental value and time.
5。 When asparagus reaches the seedling stage, it can also be sprayed on the leaves with a proper amount of chlormequat or Sanxi, which also has a good ornamental effect.
