Embodiment 1

[0024] Embodiment 1, the new application of the product taking BR and strigolactone as active ingredients in improving the resistance of apple rootstock Pingyi sweet tea to acid stress:

[0025] Dilute 0.3mg / mL BR ethanol solution and 0.8mmol / L strigolactone methanol solution at a ratio of 1:1000 with distilled water to prepare 0.3mg / mL BR and 0.8μmol / L strigolactone Aqueous solutions of novel complexes of lactones;

[0026] Sow the Pingyi sweet tea seeds soaked in deionized water for 48 hours in a pot filled with vermiculite, cultivate them in a culture room with a temperature of 25°C and a light intensity of 3000 lux for two weeks, then treat them with semi-culture solution for one week, and then use Complete nutrient solution treatment for one week;

[0027] First, 36 Pingyi sweet tea seedlings with the same growth and four leaves and one heart were selected; then, the selected Pingyi sweet tea seedlings were divided into three groups, named A, B, and C groups, with 12 tre...

Abstract

The invention discloses an application method of a novel compound in improvement of soil acid stress resistance of plants, and relates to the technical field of novel compounds of soil acid stress resistance of plants, and the effective component of the compound is a mixed solution of BR and strigolactones. According to the novel compound for improving soil acid stress resistance of plants and thepreparation method thereof, a product with a certain concentration of BR and strigolactones as effective components is sprayed to roots of plant seedlings or to leaves of the seedlings, plant growthcan be promoted, the acid stress resistance of the plant is enhanced, the growth condition of the plant under acid toxicity stress can be obviously improved, and the acid stress resistance of the plant is obviously improved so that the problem that the yield and quality of crops are reduced due to acid stress is effectively solved.

Description

technical field [0001] The invention relates to an application method of a novel compound in improving plant resistance to soil acid stress. Background technique [0002] Acid stress is one of the important environmental factors affecting plant growth, crop yield and quality. It is imminent to improve the acid stress resistance of cultivated plants, which is of great significance in agricultural production, and the existing methods of improving plant resistance to soil acid stress The application method of this method is cumbersome to operate during application, and has limited effect on improving plant resistance to soil acid stress. Therefore, a novel compound application method in improving plant resistance to soil acid stress is needed to solve the above problems. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides an application method of a novel compound in improving pl...
