Rhododendron lapponicum indoor annual sowing and seedling raising method

Abstract

The invention provides an indoor annual sowing and seedling raising method for rhododendron lapponicum, and belongs to the technical field of plant sowing and seedling raising. The seedling raising method comprises the following steps: collecting seeds; treating a sowing substrate; disinfecting the sowing substrate with a bactericide for later use; sowing: placing the sown seedling raising tray under an indoor growth light source for seedling raising; germination period management: supplementing water to keep the substrate moist in the seed germination process; seedling transplanting and seedling stage management: transplanting seedlings in a seedling raising tray into a hole tray with a seedling raising substrate, planting 1-3 seedlings in each hole, thoroughly watering the seedlings after the seedlings are transplanted, placing the seedlings under an indoor growth light source, keeping sufficient water during seedling raising, and preventing and treating diseases and insect pests; transplanting the seedlings, namely transplanting the seedlings in the hole tray into a planting container with a transplanting substrate, so as to obtain the alpine rhododendron sown seedlings. According to the method, sowing time is not limited, management is convenient, and the seedling rate is increased.

Description

Technical field [0001] The present invention relates to the field of plant seedlings, and more particularly to a seedling seedling method for a high-alpine rhododendron room. Background technique [0002] Alpine Rhododendron generally refers to a rhododendron plant that grows in a high altitude area, mostly evergreen small shrubs, high can be 3 meters. Ye Chang scattered on top of the branches, most of the technologies. Inflorescence, umbrella, has a flower, a variety of flowers, a bell, cylindrical, etc., colorful, from white, yellow, pink, red to purple, mostly flowers in 4-50 result. The sowing of the alpine rhododendron mainly has a large seedlings and sheds. Daejeon seedlings are suitable for large-scale seedlings of seedlings enterprises, and container seedlings are suitable for scientific research and a small amount of nursery. At present, the main problems in the existence of Miao Miao seedlings in the mountains, and the seedbed will choose a flat, water source conditions...

AI Technical Summary

Problems solved by technology

At present, the main problems in the cultivation of alpine Rhododendron large seedlings are as follows: 1. The sowing seedbeds will choose flat and good water conditions, build seedling greenhouses, ridges in the sheds or build seeding ponds for sowing, occupying a large area of ​​agricultural land, and from sowing It will take 1-2 years to transplant seedlings, and it will take up a large area of ​​farmland for a long time to grow seedlings, which makes the cost of raising seedlings high; 2. The large area of ​​field seedlings is large, and it is difficult to control the amount of water and fertilizer when applying water and fertilizers, which not only causes waste, but also produces Agricultural non-point source pollution; 3. Uneven sowing density in field seedling cultivation, which can easily lead to dense distribution of seedlings, easy breeding of diseases and insect pests, difficult management, and low seedling rate

The main problems of container seedling cultivation in the shed are as follows: 1. When the plug is used as the seedling container, 5-10 seeds are sown per hole according to the size of the seeds, and only 640-1280 seeds are sown in each plug, and the sowing amount is small; Rhododendron alpine The seeds are very small, and the length and width of the seeds are measured in millimeters, so it is not easy to handle; and the amount of substrate in each hole is small, the water retention capacity is weak, and the lack of water is easy to affect the germination of the seeds

2. When flower pots are used as seedling containers, the sowing substrate in the flower pot is thicker, the air permeability is poor, and it is easy to accumulate water, which will cause the roots to rot easily at the seedling stage.

Both of the above two seedling raising methods require sowing in spring (March-April). In summer, the temperature in the shed is too high, and in winter, the temperature is low and the light is insufficient. This leads to limited sowing time, concentrated time for transplanting seedlings, and a large demand for manpower input.
