Embodiment 1

[0035] Example 1 Effects of different plant growth regulators on ryegrass seed germination and seedling quality

[0036] experiment material:

[0037] Multiflora ryegrass tested variety: "Changjiang No. 2" (provided by Sichuan Agricultural University);

[0038] Test agents: α-naphthaleneacetic acid (ie naphthaleneacetic acid); 5% uniconazole wettable powder.

[0039] Test design:

[0040] The experiment was carried out at the teaching farm of Sichuan Agricultural University, using sand culture pots, and the seeds were sown on November 4, 2013. The experiment adopts a two-factor completely random design, A factor is the concentration of uniconazole, and 5 levels are set, respectively A 0 : 0mg / L, A1 : 20mg / L, A 2 : 40mg / L, A 3 : 60mg / L, A 4 : 80mg / L; B factor is the concentration of naphthaleneacetic acid, set 2 levels, respectively B 0 : 0mg / L, B 1 : 100mg / L. Each plant growth regulator solution was configured according to the experimental design and was ready for use...

Embodiment 2

[0071] Example 2 Treatment of ryegrass multiflora seeds with a plant growth regulator composition

[0072] experiment material:

[0073] Multiflora ryegrass tested variety: "Changjiang No. 2" (provided by Sichuan Agricultural University);

[0074] The configuration of the solution containing the plant growth regulator composition:

[0075] Plant growth regulator composition: according to the mass ratio of 4:10, take uniconazole and indole butyric acid, and mix them uniformly to obtain the product. Configure the amount of the solution containing the plant growth regulator composition according to actual needs, so that the concentration of uniconazole is 40 mg / L, and the concentration of indole butyric acid is 100 mg / L.

[0076] experiment method:

[0077] The experiment was carried out at the teaching farm of Sichuan Agricultural University. Sand culture pots were used to plant selected seeds with plump seeds and intact embryos in 0.2% HgC. l2 (mass volume percentage) for 5...

Embodiment 3

[0082] Example 3 Treatment of ryegrass multiflora seeds with a plant growth regulator composition

[0083] experiment material:

[0084] Multiflora ryegrass tested variety: "Changjiang No. 2" (provided by Sichuan Agricultural University);

[0085] The configuration of the solution containing the plant growth regulator composition:

[0086]The plant growth regulator composition: take uniconazole, indole acetic acid and indole butyric acid according to the mass ratio of 8:3:3, and mix them uniformly to obtain the product. Configure the amount of the solution containing the plant growth regulator composition according to actual needs, so that the concentration of uniconazole is 80 mg / L, the concentration of indole acetic acid is 30 mg / L, and the concentration of indole butyric acid is 30 mg / L. The configuration method is: dissolve with 95% ethanol first, and then dilute with distilled water to the desired concentration.

Abstract

The invention belongs to the technical field of plant propagation and discloses a plant growth regulator composition for ryegrasses. The plant growth regulator composition is prepared from uniconazole and an auxin plant growth regulator with the mass ratio of (2-8) to (6-10). When being used for treating ryegrass seeds, the plant growth regulator composition can remarkably increase the rooting rate of the ryegrasses, and the interaction effect of the uniconazole and the auxin plant growth regulator on the growth of ryegrass seedlings is remarkable, the quality of the ryegrass seedlings is remarkably improved, the sprouting and the growth of the ryegrasses are facilitated, the lodging resistance and the severe environment resistance of the ryegrasses are improved and the plant growth regulator composition is beneficial to the promotion and the application of the ryegrasses.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, in particular to a plant growth regulator composition suitable for ryegrass. 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 (L. perenne) and multi-flowered ryegrass (L. multiflorum) are cultivated grasses 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] The morphological characteristics of ryegrass are: perennial, with thin and thin rhizomes. Culms tufted, 30-90 cm high, with 3-4 nodes, soft, rooting on basal nodes. The ligule is about 2mm long; the le...
