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 200mg / L penicillin solution, soak at room temperature for 18 hours; put the soaked seeds indoors for 5 hours, then heat them to 35°C for 5 hours in a light incubator, and repeat this alternately for 24 hours. Seeds are kept 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 sandy loam, and the soil pH value is 6.9. Sta...

Embodiment 2～8

[0019] Embodiments 2-8: 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 provides a method for promoting orchardgrass seed germination... The method comprises the step of adopting penicillin solution to carry out soaking treatment on orchardgrass seeds, wherein the concentration of the penicillin solution is 100mg / L-500mg / L and the treatment time is 6-24 hours. In comparison with the ordinary seed soaking using clean water, the germination percentage, the follow-up growth performance and the like of the orchardgrass seed are improved significantly; the germinative force of the orchardgrass seed can be 75-78%; the germination percentage can be 78-83%;and the orchardgrass seed subjected to seed soaking using the penicillin solution is good in growth performance after germination.

Description

technical field [0001] The invention relates to a method for promoting germination of seeds, in particular to a method for promoting germination of duckweed seeds. Background technique [0002] Forage is an indispensable part of animal husbandry, and it is also an important bottleneck hindering the development of animal husbandry. The shortage of forage supply has intensified. In the past ten years, my country's animal husbandry has developed very rapidly. There are more and more large-scale farms, and the degree of intensification is getting higher and higher. need. 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. [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 ...
