Culture method for improving shade tolerance of herbaceous plants of gramineae

Abstract

The invention discloses a culture method for improving the shade tolerance of herbaceous plants of gramineae. The culture method comprises the following steps: (1) firstly, planting young seedlings of herbaceous plants of gramineae into a greenhouse, and controlling light, temperature and soil humidity after the seedlings are survived; (2) sequentially carrying out culture under the conditions of 29% of shade, 56% of shade, 77% of shade and 91% of shade, wherein the seedlings are cultured under the condition of 77% of shade for two seasons and are cultured under the rest conditions for one season; and (3) carrying out selfing to set fruits in each season, selecting healthy seeds for germinating and emerging, then, planting the seedlings into the greenhouse, and culturing the seedlings under the next shade condition after the seedlings are survived. Compared with the prior art, the culture method has the advantages that the forbidden zone that grass seeds of the gramineae grow under a high-shade condition is broken, the cultured grass seeds can be used for landscaping as well as water and soil conservation under the high-shade condition such as a forest land and a highway interchange, not only can a great deal of land be saved, but also the demand for seeds for greening can be met.

Description

technical field [0001] The invention relates to a cultivation method for improving the shade tolerance performance of gramineous herbaceous plants, which belongs to the cultivation method of grass plants. Background technique [0002] With the increase of my country's population and the rapid development of urban and rural construction, on the one hand, the land area is rapidly reduced, and on the other hand, the construction of urban landscape green spaces is developing rapidly, requiring a large number of lawns for greening. However, the shade-tolerant rate of gramineous herbaceous plants at home and abroad is low, generally the maximum shade-tolerant rate is below 65%, it is difficult to adapt to the environment under long-term sun-shading conditions, and the application is greatly restricted. Contents of the invention [0003] Purpose of the invention: In order to overcome the above-mentioned technical defects, the purpose of the present invention is to provide a culti...
