Embodiment 1

[0021] The invention provides a special cultivation medium for rhododendron container seedlings, which is composed of peat, green plant waste fermentation products, pine scales and yellow sand. The volume ratio of the peat to the cultivation medium is 20-30%. The volume ratio of waste fermentation products to the cultivation medium is 30-40%, the volume ratio of the pine scales to the cultivation medium is 30-40%, and the volume ratio of the yellow sand to the cultivation medium is 0-10%.

[0022] Further, the green plant waste fermentation product complies with the relevant regulations of "Technical Regulations for Disposal and Application of Green Plant Waste" (GB / T 31755-2015), wherein pH≤7.0, EC≤500μs / m.

[0023] Further, the length of the fibers in the peat is 0-70mm, pH5.5-6.0, EC less than 150μs / m.

[0024] Further, the pine scales are naturally stacked for more than 6 months after crushing, the particle size is ≤15 mm, the pH is 5.0-6.0, and the EC is ≤150 μs / m.

Embodiment 2

[0031] Embodiment 2: formula medium of the present invention implements comparative test

[0032] The seedlings used in the test are the annual cutting seedlings of Rhododendron, and the cultivation medium is prepared according to the formula (Table 1)) (volume ratio), mixed evenly and placed for 1 month, then potted, fertilized, and maintained according to conventional methods. According to the cultivation requirements of Rhododendron, 8 kinds of media were prepared in the experiment, including No. 6 medium, the high-quality medium commonly used in Rhododendron cultivation, peat: pine scale 3:1. After one and a half years of cultivation, the plant height, crown width, branch number, chlorophyll and leaf area of ​​Rhododendron in different cultivation media were counted and analyzed statistically (Table 1). According to the statistical analysis results, the growth advantage of rhododendron cultivated by the formula medium of the present invention is obvious, and the growth ind...

Embodiment 3

[0035] Embodiment 3: mycorrhizal preparation inoculation implements comparative test

[0036]The test is based on the cultivation medium of the present invention, and 3 rhododendron varieties are selected as the inoculation test object, wherein 2 are spring azalea varieties and 1 summer azalea variety. After inoculation for 1 year, investigate the growth indicators of 3 varieties, and the results are shown in the table 2. It can be seen from the results that the plant height of 'Shuangji Taohong' decreased after inoculation, and the crown width, number of branches, and leaf area all increased in the inoculation treatment; Indexes were all increased in the inoculation treatment. The number of branches and leaf area of ​​the three varieties increased significantly after inoculation, which were 16.9-35.9% and 7.8-23.5% higher than those of the control plants without inoculation. The plants after inoculation are more plump and compact.

Abstract

The invention relates to a cultivation medium special for rhododendron container seedlings. The cultivation medium is prepared from peat, a green plant waste fermented product, pine scales and yellow sand, in the cultivation medium, volume ratios of the peat, the green plant waste fermented product, the pine scales and the yellow sand are 20-30%, 30-40%, 30-40% and 0-10% respectively. The invention further provides a method of cultivating the rhododendron container seedlings. The step of preparing the cultivation medium includes the substeps that rhododendron is put into a pot according to a conventional method, mycorrhiza fungus liquid microbial inoculum is sprayed around a root system, the plant height of rhododendron is 15-20 cm, the flower pot is inoculated with 10 ml of the microbial inoculums, and earth covering curing is carried out after inoculation; after inoculation of the rhododendron seedlings is completed, slow-release particle fertilizer is applied into the flower pot, and curing is carried out. Cyclic utilization of the green waste can be promoted, the usage amount of the natural peat is reduced, the use ratio of fertilizer is increased, and plants of the cultivated rhododendron container seedlings are higher in fullness.

Description

Technical field: [0001] The invention belongs to the field of botany and relates to a rhododendron, in particular to a special cultivation medium for rhododendron container seedlings and a cultivation method thereof. Background technique: [0002] Rhododendron (Rhododendron) is a general term for plants of the genus Rhododendron in the family Rhododendron. Rhododendrons often bloom luxuriantly, with bright colors and high ornamental value. They are not only important potted flowers, but also indispensable flowers and trees in gardens. They occupy a large proportion in the flower and tree market. [0003] Rhododendrons have weak root systems, so seedlings should not be sold bare-rooted, and ground-planted seedlings sold with soil balls will cause serious damage to the topsoil of the soil. Therefore, container seedling cultivation is the trend of Rhododendron cultivation. Rhododendron has high requirements on the cultivation medium, and potted plants need to use acidic medium...
