Ecological environment of orchids

Orchid growth must have a certain natural environment, with adaptive environment, orchid growth and development, subtropical monsoon climate, more suitable for orchid growth and development. The vast mountainous and semi-mountainous areas of Jiangsu and Zhejiang abound in orchids in ancient times, and they still thrive today. The adaptation of natural environment is one of the most basic and important conditions for the growth of orchids.

Orchids grow in shady humus soil or weathered gravel soil with good drainage, and the air is humid and ventilated.

According to the ecological habits of orchids growing in the natural environment of Jiangsu and Zhejiang provinces, the requirements for climate can be summarized as follows: like warmth, fear of frost; like humid atmosphere, afraid of damp waterlogging; like sunny weather, afraid of dry wind and sun; like wind and wind, afraid of blocking and muggy. The requirements for soil quality are: humus soil with loose ventilation and good drainage, strong acid soil and clayey soil. In the Yuan Dynasty, Kong Jingzhai summed up the habits of orchids in sixteen words: "like sunny and afraid of the sun, like yin and fear dampness, like secluded and remote, like clumps and fear dense." It's quite incisive. Lu Ting Weng's "Lan Yi Twelve Wings" in the Ming Dynasty can be summarized as ten joys and ten fears: "Happy sun and fear of summer, wind but cold, rain but fear of scrawls, moisture and moisture, dry but coal, soil and thick, fat but turbid, shade and sharp, heat but smoke, joy and quiet, clustering and leaving mother, cultivation and arrogance.

Jiangsu and Zhejiang, the natural climate and geographical environment are the most suitable for orchid cultivation, and it is also the earliest birthplace of orchid cultivation. The most important thing to raise orchids is to create a similar natural environment according to the natural growth habits of orchids. Therefore, in the artificial cultivation of orchids, it is necessary to master the following:

1. Like shade

Orchids mostly grow in the shady mountain forests, green onion pet, dense trees (bushes) block the strong sun, shining on the orchids have some exposure to the sun, orchids grow in a cool place. On the other hand, strong direct light is not conducive to the growth of orchids, resulting in scorched spots of orchid leaves, or even withered yellow.

2. resistance to dryness and dampness

Dry resistance is by no means a love of drying, and a bogey of dampness is by no means not moisturizing. Orchids, like other flowers, also need rain and dew. The places where orchids grow naturally are fresh air, high humidity, easy drainage and moist soil. The key is smooth drainage and no stagnant water. Due to the uneven rainfall throughout the year and the great change of soil water content, the structure of each part of orchid plant also shows the characteristics of drought tolerance. Pseudobulbs and fleshy roots can store and absorb water.

3. Like ventilation

Orchids avoid damp and stuffy most. Orchids grow in the valley wind around the wild stream, the soil is loose and well ventilated. The orchid leaves flutter with the wind and the air is fresh, which is very beneficial to the photosynthesis and respiration of orchids.

4. Fear of pollution

Orchids live in the mountains, fresh air, clean streams, quiet environment, vigorous growth, the most afraid of air pollution, soil pollution, as well as the harm of dust.
