Embodiment 1

[0018] A vigor optimizer for improving the vigor of hybrid rice seeds, comprising trace elements, inducers, brassinolides and gibberellins, the quality of the trace elements, inducers, brassinolides and gibberellins The ratio is 10.0:3.5:5.25:2.25.

[0019] Wherein, the trace elements include Mg, Mn, Zn, Ca and rare earth elements, and the trace elements exist in the form of chelates of corresponding elements. The content of Mg in the activity optimizer is 15g / L, the content of Mn is 15g / L, the content of Zn is 75g / L, the content of Ca is 7.5g / L, and the content of rare earth elements is 1.5g / L, and The total content of Mg, Mn, Zn, Ca and rare elements is ≥100g / L.

[0020] The applicant conducted relevant experiments in a hybrid rice seed production test base in Suining County in 2016. The test base is located in a hilly area with a large temperature difference between day and night, and the average daily temperature is about 27°C. During the test, the cultivation method com...

Abstract

The invention relates to a vigor optimizer for improving vigor of hybrid rice seeds and an application method. The vigor optimizer includes trace elements, abscisic acid, brassinolide and gibberellin,and the mass ratio of trace elements, abscisic acid, brassinolide and gibberellin is 10.0:3.0-4.0:5.0-5.5:2.0-2.5. The application of the vigor optimizer can effectively balance various trace elements in the seed inclusions and increase their content, improve the resistance of the seed development process to external adverse environments, optimize seed filling and greatly promote seed vigor formation, the seed emergence rate and germination potential are improved by 1-5%, and the vigor index is increased by about 10%.

Description

technical field [0001] The invention relates to hybrid rice seed production technology, in particular to a vigor optimizer for improving hybrid rice seed vigor and a use method thereof. Background technique [0002] Seed vigor is a comprehensive indicator, which refers to the comprehensive performance of seeds in terms of germination, emergence, and seedling capacity and characteristics, that is, seeds with high vitality germinate early, have a high rate of emergence and seedling growth, and have strong adaptability to harsh environmental conditions. In addition to being affected by individual development status and seed genetic characteristics, seed vigor is also affected by many external factors, including seed development conditions (nutritional conditions, maternal vitality, planting density, light, temperature, water and air conditions), and harvest time and Post-harvest seed drying measures, all of the above are limiting factors affecting the level of seed vigor.
