Abstract

The invention relates to a composite preparation for improving heat resistance of crops and a preparation method and application thereof. The composite preparation of improving heat resistance of crops is prepared from trehalose glycolipid and glucosamine. The invention further discloses the preparation method and application of the composite preparation for improving heat resistance of crops. The composite preparation for improving heat resistance of crops is prepared into a spray agent according to appropriate proportions to be sprayed to leaves, the activity of reactive oxygen scavenging enzymes SOD, POD, CAT and APX in plants can be effectively improved, MDA content is reduced, the plant damage degree is reduced, plant growth and development are adjusted, and therefore crop quality and yield are improved.

Description

technical field [0001] The invention relates to a compound preparation for improving the heat resistance of crops, a preparation method and application thereof, and belongs to the technical field of crop stress resistance preparations. Background technique [0002] With atmospheric CO 2 With the increase of concentration, the global average temperature will increase day by day in the future. High temperatures have adverse effects on plant growth, survival and yield. Wheat is a temperate crop, and the optimum temperature for its growth is 17-23°C. Wheat is widely grown all over the world and is a very important food crop. According to statistics, about 35% of the world's population takes wheat as a staple food. Wheat accounts for the vast majority of the more than 5.84 billion hectares of arable land in the world. Wheat is also an excellent fodder for livestock, but due to its importance to humans, only a small portion of wheat is used for livestock feed. Wheat is also ...
