Problems solved by technology

[0003] The development of my country's animal husbandry is very rapid. There are more and more large-scale farms, and the degree of intensification is getting higher and higher. However, in terms of raw material supply, the supply is far from meeting the needs of the development of animal husbandry.
This gap is particularly large in pasture production

Embodiment 1

[0015] Embodiment 1: A simple and effective method for promoting seed germination. First, the seeds of Dactylis chinensis are mechanically cleaned; then the seeds are buried in cold sand at 1°C to 4°C for 27 days; 100mL / L penicillin solution, soak 15 pieces at room temperature; put the soaked seeds indoors for 5 hours, then heat them to 35°C for 5 hours in a light incubator, repeat this alternately for 24 hours, and often water some Water keeps the seeds moist.

[0016] 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 sandy loam, and the soil pH value is 6.9. State nitrogen 16.0ppm, available phosphorus 12.5ppm, av...

Embodiment 2～6

[0017] 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.

[0018] Example

[0019] 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 simple and effective 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] The development of my country's animal husbandry is very rapid. There are more and more large-scale large-scale farms, and the degree of intensification is getting higher and higher. However, in terms of raw material supply, the supply is far from meeting the needs of the development of animal husbandry. Especially in pasture production, this gap is particularly large. So how to increase the pasture yield on the basis of the existing planting area is an important problem that needs to be solved urgently. Dactylis is a well-know...
