What kind of soil is white bletilla suitable for planting? When will it be ready?

The planting method of Bletilla striata is simple, but it is necessary to master certain skills for its high yield, especially in soil selection and management techniques. What soil is suitable for Bletilla striata? When will it be ready?

Bletilla prefers warm, damp environments, such as wild valleys and forests. It is slightly hardy and can be cultivated in the open field in the middle and lower reaches of the Yangtze River. Strong negative tolerance, avoid strong light, leaves are easy to wither and yellow when high temperature and drought in summer. It is suitable for sandy loam with good drainage and high humus content. It often grows in wetter stone walls and moss layers, often combined with shrubs, or in forest margins, grass, mountain springs, and under evergreen broad-leaved forests, trees or coniferous forests at an altitude of 3200 meters above sea level. Cultivated in Beijing and Tianjin. The stones grown in Bletilla striata are sandstone, so that Bletilla striata can absorb capillary water and absorb it firmly on it.

Before Bletilla striata seedlings are formed, the seeds must be in contact with the soil.

The production and broadcast of Bletilla striata seeds mainly depends on the wind, but in the process of transmission, due to the dense leaves, a large part of them can not touch the ground, even after landing, they may be attached to the dead leaves and buried in the soil, because the seeds of Bletilla striata can not be in direct contact with the soil, so the survival rate is greatly reduced.

Requirements for soil parent materials

Generally, where the soil is fat and wet, it is suitable for the growth of Bletilla striata seedlings. After molding, the leaves of Bletilla striata are large and the tubers are thick; but compared with the soil with mostly sandy soil and low soil viscosity, the soil is easy to permeate water and fertilizer, which is not conducive to water and fertilizer conservation. Relatively speaking, the humidity, organic matter and decay content are relatively low, such a soil is not conducive to the growth of Bletilla striata, through the analysis that Bletilla striata belongs to neutral soil plants.

According to the introduction and summary of the above two points, Bletilla striata prefers wet but more drought-tolerant mesophytes, which is suitable for red and yellow sandy soils with high organic matter and decaying matter, and the PH value is between 6.57.5.

Planting time of Bletilla striata:

During the harvest from September to October, the tubers with old stalks and buds were selected for planting. In the south, it should be planted as you dig; in the north, the seeds should be stored until the following spring. After harvesting Bletilla striata, it was harvested in October of the 4th year when the stems and leaves were yellow and withered. At this time, the underground tuber has grown into 8-12, quite crowded, too late harvest, poor growth. When digging, first remove the residual stems and dead leaves on the ground, and then carefully dig the tuber with a two-toothed rake to shake off the soil and transport it back for processing.
