Embodiment 1

[0017] 1. Low-temperature training: plant Zoysia plants in pots or plugs, grow for one month, then carry out low-temperature training, use artificial climate incubator for cultivation, and light at 24°C for 16 hours, with a light intensity of 2000-3000 μmol·m -2 ·s -1 , and then cultivated at 4°C for 8 hours in the dark for 15 to 20 days, and watered normally during this period;

[0018] 2. Building the lawn: plant the Zoysia grass treated with low temperature training on the soil lawn bed according to the conventional method, and it is advisable to plant it from May to August in the northern region.

[0019] 3. N, P, and K fertilization management: apply N, P, and K compound fertilizers twice in June to August, with an interval of 30 days between the two fertilizations. , The weight ratio between K elements is 4:1:6~4:2:7;

[0020] 4. Administration of exogenous hormone ABA (abscisic acid): Administer ABA twice between August and September, with an interval of 15 to 20 days...

Embodiment 2

[0022] 1 Materials and methods

[0023] The excellent Zoysia qingdao of selected character, processing A1 (handling planting by embodiment 1 processing method), processing A2 (do not carry out above-mentioned 1,2,3 process, other planting management is identical with A1), A3 (no Carry out the treatment of the above 1, other establishment management is the same as A1). All three treatments were planted in Beijing in July 2016.

[0024] 1.2 Green period observation

[0025] The selected grass seeds were sown in the experimental field, and the grass species corresponded one by one. During the planting period, unified management was tried, and regular watering and weeding were carried out to ensure that the experimental grasses had the same growth environment, and the growth conditions were almost the same and good. From the early spring of 2017 when the lawn started to turn green to turn yellow in autumn, the green period of different treatments was observed and recorded.

Abstract

The invention discloses a method capable of improving cold resistance zoysia japonica and belongs to the technical field of lawn planting. The method includes: subjecting zoysia japonica to potting orplug planting, culturing in an artificial weather culture box after growing for one month, and allowing illumination at 24 DEG C for 16h, wherein illumination intensity is 2000-3000umol.m-2.s-1; maintaining darkness at 4 DEG C for 8h, and culturing for 15-20d. The green period of zoysia japonica planted by the method can reach more than 220d in Northern regions (like Beijing and Lanzhou where annular minimum air temperature is higher than minus 20 DEG C), and zoysia japonica can winter safely.

Description

technical field [0001] The invention belongs to the technical field of lawn planting, and in particular relates to a method for improving the cold resistance of zoysia grass. Background technique [0002] Zoysia is an important turfgrass species in my country. It is not only an excellent lawn plant and a good soil-fixing and slope-protecting plant, but also has high feeding value. Zoysia plants are warm-land turfgrass species. Because they are extremely resistant to extensive management, they are good ecological turfgrasses. They have also begun to be planted in the north of the Yangtze River in my country. However, because of its poor cold resistance, it is difficult to survive the winter safely in some northern regions. The invention provides a method for effectively improving the cold resistance of Zoysia plants. Contents of the invention [0003] Purpose of the invention: to provide a method for improving the cold resistance of zoysia to solve the problem in the prio...
