Embodiment 1

[0018] Example 1 Large-scale Misty Cutting Seedling Raising of Longevity Flower Single Petal Variety Bromo

[0019] (1) Cultivation of the female parent plant: Plant the seedlings of the longevity flower single-petal variety Bromo in a plastic flowerpot of 120*110mm in the greenhouse on June 18 as the female parent plant, and the cultivation substrate peat soil: volume of perlite Ratio=1:1; After the female parent plant is colonized and survived, spray 1500 times of foliage fertilizer every 7 days, and the foliage fertilizer is N, P 2 o 5 and K 2 O content is 30% for N content, P 2 o 5 Content is 10%, K 2 O content is the foliar fertilizer of 10%, and described percentage is mass fraction. On June 31, the height of the plant reached 15cm±1cm, and the topping began; on July 7, 3 to 4 lateral buds began to emerge. During the growth period, water thoroughly when the surface of the cultivation medium turns white. During the growth period: once a week, use 1500 times liquid o...

Embodiment 2

[0024] Example 2 Large-scale Misty Cutting Seedling Raising of Longevity Flower Double Petal Variety Fiesta

[0025] Embodiment 2 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0026] (1) Cultivation of the female parent plant: the female parent plant of Fiesta was planted on July 4th. After the female parent plants are colonized and survived, spray 1800 times liquid foliar fertilizer every 8 days, and apply 75% chlorothalonil wettable powder to 2000 times liquid; on July 17, the plant height reaches 15cm ± 1cm, start pinching, On July 30, 3-4 lateral buds began to emerge.

[0027] (2) Cutting of cuttings: cut cuttings on August 16.

[0028] (3) Cutting: The mixed fungicide sprayed through the cutting seedbed before cutting is 50% carbendazim of 1500 times liquid and 5% Jinggangmycin water agent of 1500 times liquid mixed in equal volume, and the shading rate is set above the seedbed. 80% shade net.

Embodiment 3

[0031] Example 3 Large-scale cutting propagation of longevity flower double-petal variety Leonardo.

[0032] Embodiment 3 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0033](1) Cultivation of the female parent plant: On April 3, the female parent plant of the double-petalled variety Leonardo was planted. After the female parent plant is colonized and survived, spray 2000 times of liquid foliar fertilizer every 10 days. On April 19, the plant height reaches 15cm ± 1cm, and the topping begins. On April 29, 3-4 lateral buds begin to emerge.

[0034] (2) Cutting of cuttings: cut cuttings on May 14.

[0035] (4) Acquisition of seedlings: It was observed that the longevity flower Leonardo began to root on May 20, and the root system covered the base of the entire cutting on June 3 (14 days after rooting at this time), the seedlings can be harvested and cut The seedling rate reaches 100%. The harvested seedlings are...

Abstract

The invention discloses a jonquil large-scale atomizing cuttage seedling breeding method. The method includes the steps of cultivating mother plants through soilless culture, spraying leaf fertilizer once every 7 to 10 days after the mother plants are planted and survive, and conducting pinching after the mother plants grow to 15 cm+/-1cm high; conducting thorough watering when the surface of a culture medium becomes white in the growing period, and alternately spraying bactericide once a week; dipping in rooting powder during cuttage, keeping the temperature inside an atomizing greenhouse within the range of 25 DEG C to 30 DEG C, controlling the air relative humidity to be 85% or higher, and arranging a sunshade net with the sunshade rate of 80% to 85% above seedbeds, wherein the volume ratio of turf to perlite of the cuttage medium is 1 to 2. By means of the method, the mother plants grow robust, and are high in growing speed and high in cutting slip yield; the seedlings are high in reproduction speed and can be harvested 18-20 days after cuttage, the cuttage planting percent can reach 98% or higher, jonquil seedlings can be produced on a large scale every year, and production cost is low.

Description

technical field [0001] The invention relates to a plant mist cutting seedling raising technology, in particular to a large-scale mist cutting seedling raising method for longevity flowers, which belongs to the technical field of plant propagation. Background technique: [0002] Kalanchoe, also known as Christmas Kalanchoe, Shouxing Flower, etc., is a perennial fleshy perennial herb of the genus Kalanchoe in the Crassulaceae family. Stem erect, plant height 10-40cm. Leaves are opposite, oblong-spoon-shaped, dark green. Panic cymes clustered in clusters. The flower colors are crimson, pink, orange red, yellow, orange yellow and white, etc. There are single flowers and double flowers, and the inflorescences bloom successively, and the flowering period is 2 to 5 months. Kalanchoe is a lovely winter and spring houseplant. It has a long flowering period, is resistant to drought, and is easy to cultivate. In 2012, it was ranked as the sales champion of potted flowers in Aalsmee...
