Description

Method for promoting hybrid orchid to grow seedlings in inclined planting mode

[ technical field ] A method for producing a semiconductor device

The invention relates to a method for promoting seedlings to grow by obliquely planting hybrid orchid.

[ background of the invention ]

The Cymbidium hybridum (Cymbidium hybridum) is a new orchid species bred by hybridization of traditional Chinese Cymbidium and Cymbidium hybridum, has the characteristics of unique delicate fragrance and elegance of the Chinese Cymbidium, large and numerous Cymbidium hybridum flowers, bright colors, flowers and arrows coming out of the Cymbidium and inflorescence, is favored by people, becomes a new orchid product with the most development potential in the orchid market, the annual outgoing quantity of seedlings in Taiwan area reaches 4000-5000 thousands of plants, and the annual output of commodity flowers is about 3000 thousands of pots.

Although the cultivation history is not long in China, the planting area, the scale and the yield are increased year by year, and the product becomes an important member in the overnight. At present, the domestic production of the hybrid orchid is mainly focused on the places such as Guangdong, Fujian, Yunnan and the like, the market quantity of the hybrid orchid in 2015 is about 500 thousands of pots in the period of only one night, the market demand of practitioners is predicted, the effective demand of the hybrid orchid in China is about 2000 thousands of pots, the market seedling gap is large, particularly, high-quality seedlings are not in supply and meet the demand, and how to improve the seedling emergence rate of the hybrid orchid is a technical problem of the majority of orchid lovers at present.

At present, no domestic research report about promoting early seedling and improving seedling rate of hybrid orchid by adopting an oblique cultivation method is found, so that a new oblique cultivation method of hybrid orchid is needed to be provided, the seedling growth of hybrid orchid is promoted, and the production value, economic benefit and social benefit of hybrid orchid are further improved.

[ summary of the invention ]

The technical problem to be solved by the invention is to provide a method for promoting the seedlings of hybrid orchid by oblique cultivation, which is simple and feasible, the seedlings of hybrid orchid by oblique cultivation are early in seedling growing time, the germination and seedling growing rate is high, and the grown seedlings are strong, so that the production value, economic benefit and social benefit of hybrid orchid are improved.

The invention is realized by the following steps:

a method for promoting oblique cultivation of hybrid orchid to grow seedlings comprises the following steps:

(1) oblique planting season: the temperature is stabilized above 15 ℃ in the late spring, early summer and daytime;

(2) oblique planting and dividing plants: dividing plants according to the road of mature plants of the hybrid orchid, dividing 1 pseudobulb into 1 plant, and dividing a single plant;

(3) soaking and disinfecting: soaking the pseudobulb and the root in a methyl thiomycin solution of 800-1000 times for 20-30 minutes, taking out and drying;

(4) preparing a matrix: mixing 3-5 mm small pieces of bark, coconut pieces and small stones which are soaked in clear water according to the volume ratio of 1:2:1 to obtain a planting matrix;

(5) oblique planting angle: obliquely planting the blue plants by inclining the blue plants at 30-60 degrees;

(6) oblique planting depth, namely covering half of the pseudobulb with the matrix;

(7) oblique planting: the side of the seedling faces the sun direction, and the obliquely planted orchid plants face the opposite direction; .

(8) And (3) illumination control: shading by using a shading net with the concentration of 60-70% 7-10 days before planting, and increasing illumination in the later period, wherein the illumination intensity is controlled to be 30000-60000 lux;

(9) fertilizer management: and (3) not applying fertilizer within 7-10 days after planting, additionally applying a slow release fertilizer with the N, P, K ratio of 14:14:14 at the later stage, 5-6 g per pot, and spraying a foliar fertilizer with the concentration of 1000-2000 times and the N, P, K ratio of 1:1:1 every 7-10 days.

The invention has the following advantages:

the method is simple and easy to implement, the hybrid orchid obliquely planted has the advantages that the sprouting time is short (8 days earlier than that of the conventional upright planting), the sprouting rate is high (the sprouting rate reaches 92 percent and is improved by 60 percent compared with that of the conventional upright planting), the grown seedlings are strong, and the production of the hybrid orchid is facilitated.

[ detailed description ] embodiments

The present invention will be further described with reference to the following examples.

Examples

Selecting the hybrid orchid plants which are stable at the temperature of more than 15 ℃ in the late spring, early summer and daytime, dividing 1 pseudobulb into 1 plant according to the road of the hybrid orchid mature plants, dividing a single plant, then putting the pseudobulbs and the roots of the orchid plants in 800-1000 times of methylthiomycin solution for soaking for 20-30 minutes for disinfection, taking out and airing. And (3) soaking 3-5 mm small pieces of bark, coconut pieces and small stones in clear water, and mixing according to the volume ratio of 1:2:1 to prepare the matrix.

The planting method comprises the steps of inclining the orchid plants by inclining 30-60 degrees backward, covering half of the pseudobulb with the substrate, enabling the surface of the seedlings to face the sun, and placing the obliquely planted orchid plants in the opposite direction.

Shading by using a 60-70% shading net 7-10 days after planting without applying fertilizer; and (3) increasing illumination at the later stage, controlling the intensity at 30000-60000 lux, additionally applying N, P, K slow-release fertilizer with the proportion of 14:14:14, 5-6 g per pot, and simultaneously spraying N, P, K foliar fertilizer with the concentration of 1000-2000 times of that of 1:1:1 every 7-10 days.

The experiment is divided into an oblique cultivation experiment group and a conventional upright cultivation control group, the experiment group uses the division and management method, the control group uses a conventional upright cultivation method, and the difference from the experiment group is that (1) the cultivation medium uses conventional small pieces of bark, coconut pieces and small stones, and the medium is prepared by mixing according to the volume ratio of 1:1: 1; (2) the planting method adopts the conventional upright cultivation of blue plants; (3) the planted orchid plants are placed conventionally without direction requirements; (4) shading with a shading net of 70-80% in 4 weeks before conventional cultivation, and controlling the illumination intensity at 15000-30000 lux. The management of other control groups is consistent with that of the test group, 50 plants are treated in each test group, repeated for 3 times, and randomly arranged in groups.

The average sprout time and the sprout proportion in 3 months of 2 test treatments are observed and recorded, and the test results are shown in table 1:

TABLE 1 cultivation of hybrid orchid in slant

Test method	Time to sprout (d)	Rate of New seedling (%)
			Oblique planting	26	92
Conventional upright Cultivation (CK)	34	32

The test results in table 1 show that the hybrid orchid obliquely planted is early in sprout time, the sprout rate is as high as 92% and 60% higher than that of the conventional upright planting, and the grown seedlings are strong, so that the production of the hybrid orchid is promoted, and the production value, economic benefit and social benefit of the hybrid orchid are improved.
