Embodiment 1

[0018] Embodiment 1: (the alleviating application of a kind of compound preparation to the growth of rapeseed in the process of salt stress)

[0019] The application of a compound regulator of melatonin and brassinosteroids in alleviating rapeseed stress, the steps are:

[0020] 1. Test treatment: Attach a layer of nylon mesh to a rectangular (22cmх15cmх7cm) plastic box, tighten it with a rubber band, and place it in a hydroponic box (52cmх32cmх14cm) filled with 1 / 4 nutrient solution to ensure that the liquid surface is just in contact to the nylon mesh. Select plump and uniform seeds, arrange them on nylon nets, place them in a culture room at 25°C, and cultivate them in 16 / 8h light and dark for 6 or 7 or 8 days. Then select the rapeseed seedlings with the same growing potential, insert them into a plastic plate with holes, and continue cultivating the roots by immersing them in Hoagland (Hoagland) nutrient solution. After 4 or 5 or 6 days, when the rapeseed seedlings grow 2...

Abstract

The invention discloses application of a composite regulating agent of melatonin and brassinolide to relief of the rape salt damage stress. The application comprises the steps of: a, experimental treatment: attaching a layer of nylon net to a rectangular plastic box, tightening the rectangular plastic box with a rubber band, placing the rectangular plastic box in a water culture box filled with 1 / 4 nutrient solution, arranging seeds on the nylon net, placing the rectangular plastic box in a culture room, carrying out light-dark culture, then selecting rape seedlings which are consistent in growth vigor, clamping the rape seedlings into a plastic board with holes, immersing roots of the rape seedlings into the nutrient solution to carry out culture, and waiting for the rape seedlings to grow to true leaves; b, measurement of physiological indices: after treatment, respectively measuring a plant height, a leave area, a fresh weight of an overground part and a fresh weight of an underground part of rape plants, then carrying out green removing, and after drying to a constant weight, weighing a dry weight of the rape plants; c, data processing; d, application of a composite preparation of melatonin and brassinolide. The application promotes growth of the rape plants and accumulation (the overground dry weight and the underground dry weight) of dry matter, and is simple and easy to operate, non-toxic and harmless and high in stability.

Description

technical field [0001] The invention belongs to the field of agricultural plant production, and more specifically relates to the application of a plant growth regulator in alleviating the salt stress of rapeseed, which widely participates in various physiological processes of plants, and can promote rooting, growth, seedling raising, strong seedlings, and seedling preservation. , Improve quality, increase yield, especially play an important role in regulating plant growth and development and its response to adversity. In this study, a compound preparation of melatonin and brassinolide was used to alleviate the damage of rapeseed caused by salt stress and endow rapeseed with the ability to resist adverse environments. Background technique [0002] The adaptation of crops to adversity is restricted by two factors: genetic characteristics and physiological conditions in crops, and the latter is closely related to hormones in crops. The use of plant growth regulators to enhance...
