Physical treatment method for improving seed germination rate of Wuling eremochloa ophiuroides

Abstract

The invention relates to the technical field of plant seed treatment, in particular to a physical treatment method for improving the seed germination rate of Wuling eremochloa ophiuroides. The methodcomprises the following steps: disinfecting seeds of Wuling eremochloa ophiuroides with a H2O2 solution with a mass concentration of 10%, and enabling the seeds to be completely immersed in the disinfectant; soaking the seeds for 10min; freezing the seeds of Wuling eremochloa ophiuroides at subzero 18 DEG C for 40min-50min; rinsing the seeds with distilled water, placing the seeds on a germinationbed, incubating the seeds in a set illumination incubator, and keeping filter paper moist. The method is easy to operate and low in cost, and is applied to the lawn construction of eremochloa ophiuroides; the seed germination rate can be significantly improved for the Wuling eremochloa ophiuroides; the seeds are not damaged after treatment, and the germinated eremochloa ophiuroides is not liableto mildew.

Description

technical field [0001] The invention relates to the technical field of plant seed treatment, in particular to a physical treatment method for improving the germination rate of Pseudomonas wulingensis seeds. Background technique [0002] Lawn is widely used in urban and rural greening, slope greening, environmental governance, etc. It has become the "skin" of the city and an important part of modern life. However, there are problems such as large water consumption and high maintenance costs in the construction of lawns in our country. Most of the existing lawn greening is at the cost of high energy consumption. Eremochloa ophiuroides is a warm-season turfgrass that originated in southern my country. It is also known as "Chinese turfgrass". It has the characteristics of less water and fertilizer requirements, extensive management tolerance, and strong stress resistance. my country's main lawn grass is pruned more than 8 times a year, and it needs to be watered once every 10 d...

AI Technical Summary

Problems solved by technology

This shortcoming has the following disadvantages: 1. The germination rate of False Grass is limited by low temperature treatment; 2. It is difficult for small enterprises and self-employed to plant False Grass lawns at a low temperature of -18°C; 3. 1. Since the seeds have not been sterilized, the germinated seeds are prone to mildew; 4. The target of the technology is the wild Pseudomonas, because the dormancy and firmness of the seeds of different materials and varieties of Pseudomonas are different, the same technology will germinate them The impact on the germination rate is also different. It is necessary to develop a special physical treatment method for improving the germination rate of Wuling pseudo-Jiancao

The shortcoming of this method has: 1, if scrape seed coat manually, efficiency is very low, can not satisfy the needs of large-scale establishment and planting false thrift grass lawn; But at present there is no machinery for specially processing the seeds of Pseudomonas spp., which causes the embryos of the seeds to be damaged in the process of scratching the seed coat, which seriously affects the germination rate and the growth of the subsequent Pseudomonas spp.; Inconsistent with material seed germination rate
