Plant growth regulator suitable for ryegrass and method for treating seeds of the same

Abstract

The invention discloses a plant growth regulator suitable for ryegrass. The plant growth regulator is composed of uniconazole and an auxin plant growth regulator having a mass ratio of 2-8:6-10. The invention also provides a method for treating seeds of the ryegrass. The method includes the following steps: the seeds of the ryegrass are soaked with a solution containing a plant growth regulator composition; and in the solution containing the plant growth regulator composition, the concentration of the uniconazole is 20 mg / L-80 mg / L, and the concentration of the auxin plant growth regulator is60-100 mg / L. when the seeds of the ryegrass are treated by utilizing the plant growth regulator provided by the invention, the rooting rate of the ryegrass can be significantly increased, and the interaction effect of the uniconazole and an naphthalene acetic acid on growth of seedlings of the ryegrass is significant, and the root-shoot ratio, the number of roots, the root length, the root weight,the number of leaves and the leaf weight of the ryegrass are significantly increased, while the plant height of the ryegrass significantly becomes low.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a plant growth regulator suitable for ryegrass and a method for treating its seeds. Background technique [0002] There are about 10 species of ryegrass belonging to the grass family and the genus Lolium. Ryegrass is an important cultivated pasture and green manure crop. Among them, perennial ryegrass and multiflora ryegrass are cultivated pastures with economic value. Ryegrass has become an excellent forage grass that is generally introduced and cultivated in various places. For example, perennial ryegrass has been widely cultivated in New Zealand, Australia, the United States and the United Kingdom, and is used as forage grass for cattle and sheep. [0003] Ryegrass is also one of the important forage grasses in my country. It is widely distributed in temperate regions. It has the characteristics of fast planting speed, covering ability, resistance to diseases and in...
