Problems solved by technology

However, due to the fact that the current plant growth promoters are easy to decompose or are toxic to humans, protective measures need to be taken during use

Embodiment 1

[0023] Embodiment 1: the application of melatonin in promoting the growth of rapeseed

[0024] Rapeseed seeds were sown in seedling trays, and after two weeks of cultivation, seedlings of uniform size were selected for pot experiments, and each pot was filled with humus and perlite with a mass ratio of 1:2;

[0025] After the potted plant continued to be cultivated for one week, two true leaves grew, and the aqueous solution of melatonin with a concentration of 50 μmol / L was watered, and each potted plant was watered with 100 mL;

[0026] At the same time, set up a control group (CK) - irrigate with 100mL distilled water;

[0027] The watering time is twice a week, once on Monday and Thursday at 18:00 pm;

[0028] Continue to treat for 4 weeks, the total number of times of watering is 8 times, and after the last time of watering for 12 hours, the growth-related parameters are measured;

[0029] Each treatment group selected 10 rapeseed plants, which were divided into two par...

Abstract

The invention discloses novel application of melatonin to promotion of plant growth. A product with the melatonin as an active ingredient specifically can be a water solution of melatonin or an agriculturally acceptable carrier or solvent processed to be in an existing known form through a known method. The concentration of the water solution of melatonin specifically can be 10-100 micro mol / L, preferably 50 micro mol / L. A plant specifically can be a plant seedling, preferably a rape seedling. A method for promoting the plant growth specifically can comprise the following steps: irrigating soil for plant growth with the product with the melatonin as the active ingredient. The melatonin is endogenous metabolite, can be biodegraded while increasing the yield, is nontoxic, safe and free of residue to a human body, and can be used for production of lands for growing field crops and facility agriculture.

Description

technical field [0001] The invention relates to a new application of melatonin in promoting plant growth. Background technique [0002] Melatonin (N-acetyl-5-methoxytryptamine), as a broad-spectrum physiological regulator, exists in most biological organisms. Studies have shown that melatonin can improve plant stress resistance (drought, high temperature, cold damage, etc.), and regulate plant circadian rhythm and photoperiod. Melatonin itself is an endogenous metabolite, can be biodegraded, and is non-toxic, safe, and residue-free to the human body, and can be used in the production of field and facility agriculture. [0003] In recent years, due to the extensive use of chemical fertilizers, soil fertility has decreased and cultivated land resources have been destroyed, which has had a negative impact on the sustainable development of agriculture. Plant growth promoters can promote the division and growth of plant cells and increase the yield of plants at an appropriate c...
