Heat resistance enhancer for cool-season lawn grass and preparation method thereof

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 ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the problems that the cool-season turfgrass is difficult to oversummer and have low heat resistance, and prolong the green period of the cool-season turfgrass by using a heat-resistant anti-resistance agent, thereby improving the quality of the cool-season turfgrass. Heat-resistant summer ability, the key technical problems it mainly solves are:
