Rhododendron delavayi float seedling method

Abstract

The invention discloses a Rhododendron delavayi float seedling method, comprising the following steps: (1) constructing a float seedling pool: selecting a site, constructing a pool and building a shed; (2) preparing seedling substrate: firstly crushing muck and laterite, then adding fine sand, pearlite and plant ash, and mixing evenly in the process of preparing the seeding substrate, wherein the substrate comprises the muck, laterite, fine sand, pearlite and plant ash according to the volume ratio of 5:1:2:1.7:0.3; and sterilizing the well-mixed substrate (using fumigation), adding 10% of water to evenly wet, regulating the PH value of the substrate to be 5.5-6.0 (FeSO4 is used to decrease the PH value of the substrate when the substrate is alkaline, and NaOH solution is used to increase the PH value of the substrate when the substrate is acidic); (3) panning and sowing the substrate; and (4) preparing the Rhododendron delavayi float seedling nutrient solution. By adopting the flowerflow seedling substrate and nutrient solution provided by the invention to perform Rhododendron delavayi float seedling, the seed budding is neat, and the cultured seedling has favorable growth with no plant diseases and insect pests and strong resistance, thus being suitable for large-scale industrialized production of fine quality plantlets.

Description

technical field [0001] The invention relates to the floating seedling raising technology of flowers, in particular to the lantana flower industrialized production seedling raising technology. Background technique [0002] In recent years, alpine rhododendron, as a new species in the flower market, has become increasingly popular and sought after by people. Lantana is one of the native alpine rhododendrons produced in western Yunnan. Its leaves are evergreen, its flowers are red and bright like fire, and its flowers are plump and round. It is a good garden landscape plant and potted plant. [0003] At present, the industrial development of lantana is still in its infancy, and whether the seedlings can be produced on a large scale is one of the keys restricting its industrial development. Lantana can produce a large number of seeds under natural conditions, so a large number of lantana seeds can be collected and seeded to breed seedlings. According to the existing literature...

Problems solved by technology

According to the existing literature reports, in the laboratory, if the conventional sowing method is adopted, the germination rate of lantana flower in the petri dish is about 52%, if certain chemical and physical means are used to store or soak the seeds, although lantana flower The highest germination rate can reach 92%, but the cost and process are greatly increased, and the germination in the laboratory is only based on the breakthrough of the seed coat by the radicle, which does not represent the final emergence rate; and in production, if the lantana is directly The flower seeds are sown in the seedbed, and the emergence rate is only about 45%, which increases the workload of subsequent thinning and transplanting, and increases the cost.
