Embodiment Construction

[0027] Below in conjunction with embodiment and accompanying drawing, describe in detail as follows:

[0028] 1. The structural formula of melatonin

[0029] The structural formula of melatonin is shown in formula 1:

[0030]

[0031] Two, the embodiment

[0032] 1. Planting of alfalfa

[0033] A. Disinfection of alfalfa seeds

[0034] The seeds of the commercial alfalfa variety 'Juneng 995' were selected as the material. At room temperature, the alfalfa seeds were soaked in a beaker containing 0.15% (mass) potassium permanganate solution for disinfection for 5 minutes, and then the seeds were taken out and filtered dry. ;

[0035] B. Sowing

[0036] The experimental site is yellow soil with a pH value of 5.5-6.0. Deep plow the ground before sowing, apply superphosphate 35kg / mu and ammonium bicarbonate 45kg / mu as base fertilizer, then use mechanical rotary tillage, and use 3% carbofuran 3kg / mu, 75% dikesone wettable powder 1.5kg Spray evenly into the soil per mu for ...

Abstract

The invention discloses a method of using melatonin to improve acid-aluminum resistance of medicago sativa. The method includes: 1, planting medicago sativa in soil, and performing water irrigation and drainage, seedling fertilizer application and intertilling for weeding according to weather; 2, mixing melatonin and monopotassium phosphate to form a water solution product, wherein melatonin is 150 uml / L, and monopotassium phosphate is 0.35%; 3, when plants of medicago sativa are 10 cm in height, spraying the water solution product to leaves of medicago sativa for two times at spraying frequency of one time per 10 days, wherein 45-55 L of the water solution product is applied in each mu per time. Melatonin is an amine hormone, thereby being nontoxic and harmless to plants and animals, leaf spraying application is low in consumption, quick in action and high in operability, growing of medicago under acid-aluminum stress can be promoted remarkably, chlorophyll content is increased, and yield and quality of medicago sativa are improved.

Description

technical field [0001] The invention relates to pasture production and management, in particular to a method for improving the aluminum tolerance of alfalfa by applying melatonin. Background technique [0002] Acidic soil refers to the soil with a pH value lower than 7.0, and for agricultural production, the soil pH value of the plow layer is lower than 6.6, which is acidic soil. Acidic soil accounts for 40% of the world's arable land, and accounts for about 21% of the land area in my country. It is widely distributed in the southern red-yellow soil area, and with the deterioration of the environment, the area of ​​acidic soil is constantly increasing. Aluminum is the most abundant metal element in the earth's crust, accounting for about 7% of the mass of the earth's crust. Under natural conditions, it exists mainly as aluminosilicates with little bioavailability. In recent years, due to the use of agricultural chemical fertilizers and the impact of acid rain, the soil has...
