Embodiment Construction

[0025] 1, technological process of the present invention

[0026] For solving technical problems, the solution provided by the present invention, its technical process is as follows:

[0027] Cool-season turfgrass→Spray heat resistance enhancer (PP 333 +CaCl 2 +SA+CS)→Improve heat resistance

[0028] (1) The above-mentioned cool-season turfgrass is Lexus tall fescue variety (Festuca arundinacea cv.Barlexas), select healthy seeds to sow in plastic pots, the diameter of the plastic pots is 15cm, and the depth is 11cm. Each pot is sown with 100-120 seeds , received natural light at an outdoor temperature of 20±5°C, and carried out appropriate water and fertilizer management, and conducted high temperature stress tests in groups after 30 days;

[0029] (2) The above-mentioned calcium chloride (CaCl 2 ) means: CaCl 2 The aqueous solution, its content is 20mmol / L;

[0030] (3) The above-mentioned paclobutrazol (PP 333 ) and salicylic acid (SA) refer to: the aqueous solution o...

Abstract

The invention belongs to the technical field of plant adversity tolerance auxiliary preparations, specifically relates to a plant heat resistance enhancer, and especially relates to a heat resistance enhancer for cool-season lawn grass and a preparation method thereof. According to the method disclosed by the invention, paclobutrazol, salicylic acid, chitosan and calcium chloride are selected from many chemical reagents and combined with a proper cosolvent to prepare a mixed solution for carrying out spraying treatment on the cool-season lawn grass, and the improvement effect of the mixed solution on the heat resistance of the lawn grass is observed at a high temperature. Compared with a traditional method, the method disclosed by the invention has the advantages that the phenomena of the yellowing and withering, the lowering of chlorophyll, the increasing of malonaldehyde and the low generation speed of free praline of the cool-season lawn grass at a high temperature are better inhibited. The cool-season lawn grass treated by the method disclosed by the invention is capable of keeping dark green and a good state for 15 days and longer under a high-temperature condition (38/30 DEG C, day/night), however, a control group is only capable of keeping a dark green period of about 7 days under the same condition. The method disclosed by the invention is suitable for both large-scale factory reagent production, and common greening units under certain conditions.

Description

1. Technical field [0001] The invention relates to a plant heat resistance enhancer, in particular to a cool-season turfgrass heat resistance enhancer and a preparation method thereof. 2. Background technology [0002] Turfgrass has many functions such as purifying air and water, beautifying the environment, and improving microclimate. It has been paid more and more attention in the process of modern ecological city construction, and is widely used in residential areas, roadsides, industrial parks and other places. Turfgrass can be divided into cool-season and warm-season turfgrass according to the optimum temperature for its growth. The optimum growth temperature of cool-season turfgrass is 15-24℃, which is relatively lower than that of warm-season turfgrass. The cool-season turfgrass has a relatively long green period and is widely used in many areas of our country. Therefore, the problem of oversummering of cool-season turfgrasses has always been a research hotspot and ...
