Method for regulating chlorophyll content in rice leaves

Abstract

The invention discloses a method for regulating chlorophyll content in rice leaves. The method comprises the steps of conducting germination on rice seeds in deionized water, cultivating rice seedlings with a hydroponic nutrient solution, cultivating the obtained rice seedlings in the hydroponic nutrient solution in which o-dihydroxybenzene is added from the rice seedling stage for regulating thechlorophyll content, stopping the cultivation until the end of the rice tillering preliminary stage, and completing the adjustment of the chlorophyll content of the rice leaves. The method uses the o-dihydroxybenzene as a growth regulator of exogenous crops, and can effectively regulate the content of chlorophyll in the rice leaves, the action period is a critical period of rice vegetative growth(from the rice seedling stage to the tillering preliminary stage), thereby affecting rice biomass and yield, the operation process is simple, the operating conditions required are not high, and the environment protection pressure is alleviated.

Description

technical field [0001] The invention belongs to the field of rice planting, and in particular relates to a method for regulating chlorophyll content in rice leaves. Background technique [0002] Rice is the most widely planted area in the world and one of the most important food crops for human beings, providing food for more than 60% of the world's population. Paddy soil is the largest agricultural soil in the red soil region of southern China, accounting for about 56% of the total cultivated land in the region, and the unique climatic conditions can support the planting of double-cropping rice and winter rotation of rapeseed, which is helpful for saving resources and increasing rice production Play an important role. Continuous cropping obstacles caused by long-term continuous cropping are important factors affecting crop growth. Taking certain measures to alleviate continuous cropping obstacles, promote rice growth, and increase grain production is one of the important w...

Problems solved by technology

However, at present, the method of increasing the chlorophyll content of rice is generally by adjusting the nitrogen level of the plant and the light intensity, but the above method still has certain shortcomings: not only the operation process is complicated, the control conditions are strict, and it is easy to cause environmental pollution and waste of resources.
