Problems solved by technology

Jiang Jian et al. (patent publication number: CN102197727A) proposed that the germination speed and uniformity of bluegrass grass can be improved by He-Ne laser irradiation and variable temperature technology, but the equipment and conditions of general units of this irradiation technology are difficult to meet, and it is difficult to Difficult to apply to actual engineering, lack of an effective method that can be easily applied to ordinary engineering to quickly improve the germination speed and uniformity of Poa annua

Embodiment 1

[0029] A method for rapid germination of seeds in bluegrass lawn establishment, comprising the steps of:

[0030] 1) Remove impurities from the bluegrass seeds, keep the temperature at 25 / 25°C (12h / 12h, the same below), change temperature -10 / 20°C, 24h, change temperature -10 / 20°C, 48h, change temperature -10 / 20°C, 96h , variable temperature-5 / 25℃, 24h, variable temperature-5 / 25℃, 48h, variable temperature-5 / 25℃, 96h, variable temperature-0 / 30℃, 24h, variable temperature-0 / 30℃, 48h, variable temperature-0 / 30℃, after 96h treatment;

[0031] 2) Spread the bluegrass seeds in a special device for pine bark, and adjust to the second gear to loosen the seed coat for 10 minutes, so that the seed coat and germination inhibitors are properly separated from the seeds to facilitate seed imbibition and germination;

[0032] 3) Soak the seeds with 50-300mg / L gibberellin at 4°C for 24 hours after the pine bark is finished, and replace the solution at 4°C every 6 hours, so that the seeds c...

Embodiment 2

[0037] A method for rapid germination of seeds in bluegrass lawn establishment, comprising the steps of:

[0038] 1) Remove impurities from the bluegrass seeds, and treat them for 96 hours at a variable temperature of -5 / 25°C for later use;

[0039] 2) Spread the bluegrass seeds in a special device for pine bark, and adjust to the second gear for 5 minutes, 10 minutes, and 15 minutes for 5 minutes, 10 minutes, and 15 minutes to loosen the seed coat, so that the seed coat and germination inhibitors are properly separated from the seeds to facilitate seed swelling and germination;

[0040] 3) Soak the seeds with 50-300mg / L gibberellin at 4°C for 24 hours after the pine bark is finished, and replace the solution at 4°C every 6 hours, so that the seeds can fully absorb water and absorb hormones to promote germination;

[0041] 4) Filter out the seeds, dry the surface moisture, and add insect repellant for sowing.

[0042] The effect is: the effect of pine bark treatment on the ge...

Embodiment 3

[0045] A method for rapid germination of seeds in bluegrass lawn establishment, comprising the steps of:

[0046] 1) Remove impurities from the bluegrass seeds, and treat them for 96 hours at a variable temperature of -5 / 25°C for later use;

[0047] 2) Spread the bluegrass seeds in a special device for pine bark, and adjust to the second gear to loosen the seed coat for 10 minutes, so that the seed coat and germination inhibitors are properly separated from the seeds to facilitate seed imbibition and germination;

[0048] 3) Soak the seeds with 50-300mg / L gibberellin at 4°C for 6, 12, and 24 hours after loosening the bark, and replace the solution at 4°C every 6 hours to make the seeds fully absorb water and absorb hormones to promote germination;

[0049] 4) Filter out the seeds, dry the surface moisture, and add insect repellant for sowing.

[0050] The effect is: the effect of gibberellin soaking treatment on the germination of bluegrass seeds is as follows: image 3 Show...

Abstract

The invention discloses a quick germinating method for seeds in bluegrass turf establishment. The quick germinating method comprises the following steps: removing impurities from bluegrass seeds, after change-temperature treatment, horizontally tiling the bluegrass seeds in a special seed coat loosening device to loosen the seed coat; putting the coat-loosened seeds into 50-300mg / L gibberellin solution for soaking for 6-24 hours at 4 DEG C; after filtering out the soaked seeds, drying the water on surface by airing, adding an insect repellent agent to perform normal seeding and later-stage management when the seeds are in imbibition state and the moisture content of the seeds is 90-98%. The invention also discloses a special device for the quick germinating method for seeds in bluegrass turf establishment. The quick germinating method has the beneficial effects that the seed dormancy can be quickly broken and the germinating rate can be over 80% within 3-5 days by virtue of performing change-temperature treatment which is simple and easy to operate, soaking and coat loosening on the bluegrass seeds, the emerging of seedlings is in order, the competitive power between the seedlings and the weeds is strengthened, the management difficulties are reduced, the later-stage growth trend of the turf is relatively good, and the bluegrass turf establishment time is greatly reduced.

Description

technical field [0001] The invention relates to the field of seed cultivation, in particular to a method for rapid germination of seeds in bluegrass lawn establishment and a special device thereof. Background technique [0002] Bluegrass (Poa pratensis L.) belongs to the perennial herbaceous plant of the Poaaceae genus. Because of its creeping thin rhizomes, light-loving and shade-tolerant, and strong cold resistance, the leaves are bright and dense, and the plant growth point is short and easy to grow. Its other advantages, in the cold semi-arid and arid environment in northern my country, can usually grow well and survive the winter safely, so it is used as an important grass species for the construction of northern lawns. However, in the actual planting process of the lawn, due to the slow germination speed and irregular germination of bluegrass seeds, it usually takes 15-20 days to germinate, resulting in slow lawn formation and poor competition ability between seedlings ...
