Problems solved by technology

In many literatures, high temperature stress can cause different degrees of damage to plant cell membranes, and the selectivity of cell membranes will be lost or reduced.
At the same time, in order to solve this problem, scholars have found in some studies that the use of plant growth regulators can deal with the growth and development of seedlings, control vigorous growth and promote weakness, and achieve the purpose of strong seedlings, but the specific steps and implementation methods are still under development. In the process of research and exploration
[0003] At present, there are still technical problems such as slow growth rate in high temperature weather and low oversummering rate in the planting process of duckweed in the low-altitude areas of southwest China, which need to be solved urgently

Abstract

The invention provides a cultivation method for improving the summer-over rate of dactylis glomerata. The method comprises the steps of matrix preparation, seeding, treatment after germination, transplanting and the like. By means of the method, the dactylis glomerata can quickly grows in the planting process, the plant height is quickly increased, 14 days after treatment cultivation, the plant height can reach 48.2 centimeters, the leaf length is quickly increased, and 14 days after cultivation, the leaf length can reach 43 centimeters; the leaf width is quickly increased, and 14 days after cultivation, the leaf width can reach 0.7 centimeter. The tiller number is large and can reach 5; the chlorophyll content is high and can be up to 46.72 mg / g; the summer-over rate is high. The method is simple, reliable and worthy of market application and popularization.

Description

technical field [0001] The invention mainly relates to the field of cultivation technology, in particular to a cultivation method for improving the oversummer rate of Dactylis chinensis. Background technique [0002] Dactylis glomerata L. originated from Europe, North Africa and temperate Asia. It is an important perennial herbage in the genus Dactylis glomerata, and it is also an important herbage widely cultivated in the world. There are abundant germplasm resources of wild duckweed widely distributed in the temperate zone of our country, and many fine germplasms have been domesticated and utilized and contain rich and excellent genetic resources, which have great potential for development and utilization. With the deepening of research on the utilization of forage grass, the research and application of duckweed began in northern my country. Dactylis chinensis likes a mild and humid climate, and the temperature between day and night is 12 to 22°C, which is the most suitab...
