Seed initiator and application method thereof

Abstract

The invention discloses a seed initiator, which comprises the following active components in percentage by weight: 1%-5% of nitric acid rare earth, 0.05%-0.15% of gibberellin GA3, 0.1%-0.5% of vitamin C and the balance being water, wherein seeds are soaked with the initiator prepared from the components for 12 hours at the seed-medicine ratio of (1 to 1) to (1 to 4) and then are dried into original weight at 35 DEG C; the initiator has a good initiation effect on crop seeds after initiating, so that the phenomenon of rotten seeds and seedlings is obviously reduced; the indexes such as the emergence rate, the plant height and the fresh weight are obviously improved, and are obviously superior to those of a single agent of the components and a common initiator; a good synergistic facilitation effect is displayed; the seed initiator is a good initiator applied to the crop seeds; and the initiator is available in active compound, low in cost and convenient to prepare.

Description

technical field [0001] The invention relates to a mixture composed of a growth regulating substance, a nutrient element and an antioxidant for seed treatment, in particular to an initiator for activation and initiation treatment of crop seeds before germination. Background technique [0002] As the starting point of crop growth and development, seeds carry all the genetic genes, and their quality determines the growth and development of plants and the final yield to a large extent. Seed vigor reflects the potential germination and emergence ability of seeds under various conditions, and is an important indicator to measure the quality of seeds. my country is a big food producing country, and seeds play a very important role in the sustainable development of agriculture in our country. How to ensure the high vitality of seeds has become a research hotspot. [0003] When the seed is physiologically mature, its vitality reaches the highest point, and then, life will advance to...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the seed initiators on the market are hormones and inorganic salts, which are not ideal for seed initiation. In this study, growth-regulating substances, nutrient elements and antioxidants were mixed together in proportion to be used as crop seed initiators. Crop seeds have a good triggering effect, significantly reducing the rotten seed rate, and significantly improving the germination rate of seeds, plant height and fresh weight and other indicators
