Abstract

The invention provides a compound preparation for improving osmotic stress resistance of rice seedlings, a preparation method and application thereof. The compound preparation is composed of ammoniumgluconate and small molecular organic acid potassium, wherein the organic acid potassium is potassium formate, potassium acetate or potassium propionate. The compound preparation of the invention caneffectively improve the osmotic stress resistance of rice seedlings, improve the drought resistance of the rice seedlings and promote the growth of the rice seedlings.

Description

technical field [0001] The invention relates to a compound preparation for improving rice seedling resistance to osmotic stress, a preparation method and application thereof, and belongs to the technical field of crop drought stress resistance. Background technique [0002] my country is one of the countries with severe water shortages in the world. The per capita possession of water resources ranks 109th in the world, and it is listed as one of the 13 countries with severe water shortages in the world. The arid area accounts for more than 1 / 2 of the country's land area. The rainfall is 50-250 mm, and the soil moisture is very lacking. Due to the drought, the growth of crops has a huge loss every year. Drought is the most important abiotic stress factor affecting agricultural and forestry production, and osmotic stress caused by drought is one of the important causes of crop damage. [0003] my country's agricultural water use accounts for about 70% of the total water. Rice...
