Abstract

The invention discloses a plant growth regulator for enhancing drought resistance of rice. The plant growth regulator comprises ferrous chloride and salicylic acid derivatives, wherein a mass ratio of the ferrous chloride to salicylic acid derivatives is 1:(0.5-2). The invention further discloses a dosage form of the plant growth regulator. Experimental results show that the plant growth regulator disclosed by the invention can achieve the effects of improving the chlorophyll content at the later stage of the rice, increasing the functional leaf-area index, improving the photosynthetic properties at the later stage of the rice, improving the photosynthetic efficiency, effectively reducing malondialdehyde content in the leaves, slowing down ageing of rice leaves, increasing dry matter accumulation, promoting milking and increasing the yield.

Description

technical field [0001] The invention relates to the field of agricultural plant growth regulators, in particular to a plant growth regulator for enhancing the drought resistance of rice. Background technique [0002] Rice is an important food crop in my country, and it is also the crop that consumes the most water. Traditionally, it is mainly planted in paddy fields flooded with water (field water layer 3-10cm). my country is one of the 13 water-poor countries in the world, and it is also a large agricultural country. Agricultural water consumption accounts for 70-80% of the total water consumption, especially in arid and semi-arid areas. The agricultural water consumption reaches more than 90%, while the total water consumption of rice fields accounts for More than 65%. Therefore, drought caused by water shortage is the main factor limiting rice production. China's water and land resources are unevenly distributed in time and space, with more water and less land in the sou...
