Embodiment 1

[0017] Embodiment 1: A kind of method for promoting the germination of Dactylis chinensis seeds, first carry out mechanical cleaning to Dactylis chinensis seeds; Then bury the seeds in the cold sand of 1 ℃~4 ℃ and carry out sand storage for 30 days; After sand storage, use concentration Soak in 200mL / L penicillin solution at room temperature for 18 hours; place the soaked seeds indoors for 5 hours, then heat them to 35°C in a light incubator and place them for 5 hours, repeat this alternately for 24 hours, and pour some water frequently Keep the seeds moist.

[0018] Sow the above-mentioned treated duckweed seeds. The sowing area is in the west of Chongqing, which belongs to the subtropical monsoon humid climate. The annual average climate is about 18°C. ~29°4l′, the annual rainfall is 1099mm, the annual active accumulated temperature is 6383°C, the annual sunshine is 1083h, the relative humidity is 72%, and the annual average temperature is 17°C; the cultivation soil type is ...

Embodiment 2～6

[0019] Embodiments 2-6: Carry out according to the following steps and parameters, and the rest of the operating methods are the same as in Embodiment 1.

[0020]

[0021] The germination potential of the above-mentioned duckweed seeds is 80-85%, the germination rate can reach 85-88%, and the seed germination coefficient is 15.25-16.56; the leaf length of the plant measured 20 days after emergence is 18.12cm-19.36cm. The area is 7.24~7.98cm 2 40 days after emergence, the leaf length of the plant measured was 30.45cm~32.84cm, and the plant leaf area was 12.89~13.67cm 2 .

Abstract

The invention relates to a method for promoting seed germination. According to the invention, a penicillin solution is utilized to carry out seed soaking treatment on cocksfoot seeds, wherein the concentration of the penicillin solution is 100-500 mg / L, and the treatment time is 6-24 hours. The germination rate of the cocksfoot seeds, subsequent growth property and the like are obviously enhanced as compared with the conventional clear water seed soaking, the germinative force of the cocksfoot seeds can reach 75-78%, and the germination rate can reach 78-83%; and the germinated cocksfoot seeds, which are subjected to seed soaking in the penicillin solution, have favorable growth property.

Description

[0001] The application of the present invention is a divisional application with the application number 201210196504.6, the application date of June 14, 2012, and the title of the invention "a method for promoting the germination of Dactylis duckweed seeds". technical field [0002] The invention relates to a method for promoting germination of seeds, in particular to a method for promoting germination of duckweed seeds. Background technique [0003] Dactylis glomerata is a well-known vegetation in the art and is a forage material widely used in animal husbandry, but it also has unique plant physiological characteristics; Dactylis glomerata L. is a perennial Herbs, sparse bushy. The fibrous root system is densely distributed in the soil layer of 10-30 cm, and the depth can reach more than 1 meter. Stem erect or base genuflected, 70-120 cm high (cultivated up to 150 cm or more). Leaves slightly glabrous, usually closed to above the middle, with ridges on the upper part; lig...
