Description

Method for breeding large fructus xanthil palace

Technical Field

The invention belongs to the field of introduction, domestication and propagation of plants.

Background

The fructus Xanthii palace (Bowiea volubilis) is a succulent root tuber plant of genus Xanthium (Bowiea) of family Liliaceae. Native to south africa. It features a green large bulb with maximum diameter up to 20 cm, light green surface and lustre. Leaves are degenerated into linear shape, and grown plants are often lost when being seen on the seeding seedlings and young plants. The flower stem grows out from the top end of the bulb, and is wound and climbed to a high place, so that the flower stem looks like fluffy hair and can grow for more than 2 meters. Is one of the representative species of the stem-like succulent plants which are the most popular internationally at present.

At the end of the twentieth century, some succulents fans began to introduce the fructus xanthil palace as a potted ornamental plant, and the plant research institute of the national academy of sciences of Jiangsu province, 2007 began to introduce fructus xanthil palace seedlings from south Africa for a potted introduction and domestication test and then perform cultivation and breeding work of the fructus xanthil palace. The conventional method for breeding the large fructus xanthil comprises seed seedling culture and plant division propagation. The invention provides a novel method for breeding large fructus xanthil palace, which comprises the following steps: the bulb propagation is adopted, so that key technologies of processes of bulb seedling selection, slicing time, an operation method, a culture medium, field planting of bulb buds, bulb bud management and the like are solved, and the method is a rapid method for the fructus xanthii palace propagation.

Disclosure of Invention

The invention aims to solve the problems that seeds of the large fructus xanthil are not easy to obtain, the germination period of the seeds is long, the growth of seedlings is slow and the seedlings are difficult to grow. The above problems can be effectively solved by adopting the large-cocklebur palace bulb propagation.

Selecting seedlings: selecting the Roughage palace seedlings with the seedling age of 3-5 years, and requiring the plants to grow robustly without diseases and insect pests. Cutting flower stems before slicing fructus Xanthii palace bulb, stopping watering, placing in shady and ventilated place, and cutting into pieces when fructus Xanthii palace bulb is slightly dehydrated.

Selection of bulb propagation and cutting time: the time for cutting the bulb of the large fructus xanthil palace is selected to be 7 last ten days after the plum rain season is finished.

The bulb propagation and cutting operation method comprises the following steps: after being cleaned, the cutter is naturally dried and is soaked in 0.5 percent potassium permanganate solution for ten minutes before use. The bulb of the large canna hall is cut along the base part by a sterilized cutter, and then the cut bulb pieces are cut into pieces with the width of about 3 cm along the longitudinal direction. The incision is coated with carbendazim and then placed in a cool and ventilated place.

Planting a substrate: the volume ratio of the matrix is peat soil, red jade soil and plant ash is 1: 1.

Planting bulbil buds: after 10-20 days, callus is formed at the base of the phoma stipulata, certain canna microphylla buds appear, when the diameter of the bulbus buds is about 1 cm, the bulbus buds are taken down, carbendazim is coated on the wound, and the cauliflower is fixedly planted on a prepared substrate.

And (3) managing bulb sprouts: watering once in 7 days in the growing season, watering once in 20 days in winter, wherein the temperature cannot be lower than 8 ℃ and is higher than 40 ℃, and the temperature in the morning in summer is 9: 00 to 4 in the afternoon: 00 the device is shaded by a 60% shading net to enhance ventilation. In 10 months, the leaves and the flower stems of the large fructus xanthii palace begin to grow, and the large fructus xanthii palace bud seedlings grow well. The bulb of the large fructus Xanthii palace of the seedling is 3-5cm after one year.

The invention has the beneficial effects that:

the breeding of the large fructus xanthil palace has two conventional methods at present: the method provides a new propagation method of the large fructus xanthil.

The method for breeding the bulbs is adopted, so that the problems that seeds are not easy to obtain and seedling management is not easy to achieve are solved, the operation is simple and convenient, the popularization is easy, the breeding coefficient is improved, and good economic and social benefits are achieved.

Detailed Description

The following describes a detailed embodiment of the present invention with reference to the accompanying drawings.

Example (b): the method for breeding the bulbus of the fructus xanthil comprises the following steps:

(1) selecting large fructus xanthil seedlings with smooth bulbs, no plant diseases and insect pests and good growth vigor, wherein the large fructus xanthil seedlings are 3-5 years old;

(2) the time for cutting the bulb of the large fructus xanthil palace is selected to be 7 last ten days, the plant of the large fructus xanthil palace is moved to a cool and ventilated place, watering is stopped, and the cutting is carried out when the phosphor stem of the large fructus xanthil palace is slightly dehydrated;

(3) an operation method of the canna edulis bulb cutting block comprises the steps of cutting off a bulb slice of the canna edulis bulb along a base part by using a cutter sterilized by 0.5% potassium permanganate solution, and longitudinally cutting the cut bulb slice into bulb blocks with the width of about 3 cm;

(4) treating large fructus Xanthii palace bulb blocks, and coating carbendazim on cut openings of the cut large fructus Xanthii palace bulb blocks;

(5) placing the treated large-cocklebur bulb blocks in a cool and ventilated place to avoid direct irradiation of sunlight and keep ventilation;

(6) taking down the bulb buds when the bulb buds grow to be about 1 cm in diameter, and coating carbendazim on the wound;

(7) planting a substrate, wherein the volume ratio of the substrate to peat soil to red jade soil to plant ash is 1: 1;

(8) planting the bulbs of the large fructus xanthil in a prepared matrix to ensure that the whole bulbs are exposed outside the matrix;

(9) management of bulb sprouts, 9 am in summer: 00 to 4 in the afternoon: 00, shading by a 60% shading net for strengthening ventilation, wherein the temperature cannot be higher than 40 ℃ in summer, water is poured once in about 7 days in a growing season, water is poured once in about 20 days in winter, and the temperature cannot be lower than 8 ℃ in winter;

(10) in 10 months, the leaves and the flower stems of the large fructus xanthii palace begin to grow, and the large fructus xanthii seedlings grow well. The bulb of the large fructus Xanthii palace is 3-5cm after one year.
