Abstract

The invention discloses a compound preparation for relieving corn drought stress as well as a preparation method and application thereof, belonging to the technical field of crop stress-resistant preparation. The compound preparation disclosed by the invention is classified into a seed coating agent and a plant spray agent and contains the components such as trehalose glycolipid, betaine and calcium superphosphate; and the components are uniformly mixed and stirred according to certain proportion. After coating treatment of the seeds according to a suitable proportion, the seed germination can be effectively promoted, the seedling vigor is enhanced, the overall water regime of corn plants under drought stress is relieved, the damage degree of the plants is lightened, and the growth and development of the plants are adjusted so as to improve the corn quality and yield. By adopting the plant spray agent, a little effect of sprinkling irrigation water supply also can be realized; and the trehalose glycolipid also can realize certain inhibitory effect on the pathogenic bacteria of leaves.

Description

technical field [0001] The invention relates to a compound preparation for relieving drought stress of corn, a preparation method and application thereof, and belongs to the technical field of crop stress resistance preparations. Background technique [0002] As the second largest crop in the world, corn is the most important source of food and feed, and one of the major food crops with the largest demand and wide application fields in my country. [0003] The spring sowing corn area in northern China is dominated by the three northeastern provinces, Inner Mongolia and Ningxia. Due to poor weather conditions during sowing, especially drought and water shortage, the germination rate of corn seeds is low and the growth of seedlings is weak, which ultimately affects the yield of corn. Therefore, how to make the maize seeds sown in the northern dry fields have sufficient water and nutrition to promote their germination and seedling growth is the key to increasing the maize yiel...
