Propagation management of potted cliff chrysanthemum

Propagation management of potted cliff chrysanthemum

Cliff chrysanthemum is a kind of chrysanthemum pruning planting method, making use of the characteristics of many branches, soft branches and close flowering, imitating the natural posture of wild chrysanthemum hanging in the mountains, the branches show a drooping cliff shape, and the bamboo frame is used to induce forward, timely coring, so that it has a soft and curved trunk line, with uniform distribution of side branches, narrow front and rear width, full flowers, consistent florescence, and winning by length, up to more than 10 meters. Because of the different plant morphology, cliff chrysanthemum can be divided into two types: one is to prune the plant to shield-shaped, which is called forward drooping type, also known as Kanto type, and the other is trimmed to "Zhi" shape [Yoshanhua Yao].

Cliff chrysanthemum flowers covered with branches, green leaves, from a distance like dragons exploring the sea, close view just like a golden waterfall; because the plant is unique, elegant style, especially arranged in rockery streams; clear streams show the reflection of cliff chrysanthemum, very poetic.

I. seed selection and reproduction

1. The variety of small chrysanthemum should be selected, such as tough stem, long internodes, many branches, fast growth, dense flowering, prosperous growth, obvious apical advantage and strong disease resistance; the flower color depends on the need, and the bright color is better. White, yellow and red are more commonly selected; 'Button White', 'handful of Snow', 'macaroni Yellow', 'Mantianxing' and 'Button Yellow' are often selected.

two。 Cutting propagation is often used for propagation, and cutting materials are mostly selected from the root parts of old plants with strong growth, tough stems and easy to branch, to pick new foot buds, and the two foot buds had better be picked together and planted in the pot. The cutting time often varies according to the specifications of the nursery; for example, when coming out of the nursery, the length of the crown is required to be more than 3 meters, mostly from November to December of last year, 1 meter long from January to February of that year, and 0.5 meters long from April to May of the same year.

The so-called foot bud refers to the new bud from the root of the mother plant, cut 5cm from the top and transplanted to a pot with a caliber of 15cm after 10 to 15 days; if the foot bud is short and stout, it can be dug up with the root and planted directly in a small basin; after planting, it should be placed in a ventilated and transparent place, and light fertilizer (mainly potash fertilizer and nitrogen fertilizer) should be applied on time to promote its growth.

2. Turning basin and planting

1. Before planting, you usually need to turn the pot once, especially when the length of the chrysanthemum is more than 1 meter, and then plant it. The cultivated soil should choose the loam rich in organic matter, and sometimes some sawdust can be mixed to facilitate its drainage and ventilation. When the breeding seedlings grow to 15 cm to 20 cm, they can be transplanted into a pot with a diameter of about 20 cm and 25 cm. Appropriate base fertilizer should be added when turning the basin to increase its growth.

Fertilizers with a nitrogen, phosphorus and potassium ratio of 20-10-20 are commonly used for fertilization; calcium and magnesium fertilizers are occasionally applied to promote the healthy growth of the plant; when the plant grows to 20-25 cm, a bamboo branch is inserted at its base, tilting slightly toward the sunshine, and the main branch is gently tied along the bamboo branch, one place every 1-3 nodes; when the plant grows to 40-50 cm, it is planted in a pot with a diameter of 30-40 cm. At this time, the bottom of the basin should be covered with a layer of gravel or rubble of 4cm or 5cm, and appropriate base fertilizer should be added to the bottom and periphery; at the same time, a pre-compiled bamboo pad should be inserted into the basin at the same time, and the length and shape of the bamboo pad should be determined according to the idea.

The main branch of the cliff chrysanthemum is gently tied to the bamboo piece in the middle of the bamboo mat every 4 to 5 nodes, so that the main branch can grow along the direction of the bamboo mat; when the cliff chrysanthemum crown grows to a certain weight, wooden strips can be added under the bamboo mat to prevent the bamboo mat from sinking. so that the cliff chrysanthemum is hurt.

III. Management

1. Coring and reshaping side branches are important steps in cultivating cliff chrysanthemum. In order to cultivate a beautiful cliff chrysanthemum, the key is to leave 6 leaves at the base of the plant, 4 leaves to 5 leaves in the middle, and 2 leaves to 3 leaves at the top, and 2 leaves to 3 leaves in the secondary branches regenerated later. This repeated several times, so that the lateral branches can quickly grow into small lateral branches, so repeated growth, can make cliff chrysanthemum branches and leaves luxuriant and plump, flowers numerous, attractive.

As the cliff chrysanthemum plant can be more than 1 meter long, the upper and lower parts of flowers bloom for different times, affecting its ornamental value. The purpose of plastic surgery is to make the flowers bloom at the same time, neat and beautiful. Plastic surgery is usually done in September, usually at the base, then in the middle, and finally at the end. When the buds are formed, the buds with uneven or protruding surfaces should be cut off at the right time. When the flowers bloom, the flowers will fill the branches and the green leaves will accompany them at the right time, so you can get the best cliff chrysanthemum.

two。 Watering and fertilizing water are very important for the growth of cliff chrysanthemum, especially in the growth stage, watering should be properly watered every morning; the amount of water should be maintained for one day, and a sprayer is used to spray on the leaves at night to increase air humidity and restore vitality to the leaves that do not grow well. After White Dew, appropriate amount of water should be watered before evening, otherwise the differentiation of flower buds will be affected. Cliff chrysanthemum is usually not allowed to water in the hot sun, so as not to damage leaves and flower buds; overcast and rainy weather should depend on the basin soil conditions, or less watering, or no watering; in case of continuous rainy days, the stagnant water in the basin should be removed in time. [Jishan Huayao]

Fertilization should be diligent, less, refined, more keys; each time to change the basin, it is appropriate to apply base fertilizer, in order to consolidate the root. Nitrogen fertilizer and potassium fertilizer solution should be used for topdressing after the Mid-Autumn Festival to facilitate absorption. After each coring, nitrogen fertilizer with a concentration of 0.3%-0.6% should be applied to promote the formation of leaf buds and flower buds; after the formation of flower buds, a mixture of potash fertilizer and phosphate fertilizer of the same concentration should be applied, spraying the leaf surface every 5 days for 3 to 5 times; after the flower buds are transparent, they will no longer apply fertilizer to keep the potted soil moist.

3. Cliff chrysanthemum with light and ventilation is a positive plant with happy sunshine, so the pot should be placed in a place with sufficient sunshine and good ventilation, otherwise it will not only grow poorly, but also prone to diseases and insect pests.

Sometimes, the light should be increased to more than 14 hours a day between August of the planting year and March of the following year, in order to restrain the emergence of buds in the same year, so that the flowering time can be uniform; if the natural light cannot reach 14 hours, the light should be replenished artificially to make up for the lack of natural light. The cliff chrysanthemum does not need shade except in the afternoon when the hot sun is hot.

4. The common diseases of cliff chrysanthemum include black spot, rust and leaf spot. 75% chlorothalonil 50 times 800 times solution and 50% thiophanate 1000 times solution can be used alternately once a week to obtain good control effect.

Insect pests include curly worms, aphids, red spiders, cabbage insects, etc., and can also be killed by spraying 1500-2000 times of cypermethrin and 1500-2000 times of omethoate.
