Abstract

The invention discloses a spraying agent for increasing the yield of hybrid rice seed production as well as a preparation method and application thereof. Every liter of the spraying agent comprises the following components: 1 to 3 mmol of methyl dihydrojasmonate, 2 to 6 mmol of gamma-aminobutyric acid, 0.03 to 0.08 mmol of gibberellic acid '920', 0.3 to 0.8 mmol of calcium chloride, 0.05 to 0.15 mmol of sodium nitroprusside and the balance of water. The spraying agent disclosed by the invention can significantly increase the yield level of the hybrid rice seed production in various regional climates and shorten the grouting time of rice ears, and is beneficial to improving the seed quality commercial product indexes such as the germination potential, germination rate and the like of hybridrice species.

Description

technical field [0001] The invention belongs to the technical field of rice seed production, and in particular relates to a spraying agent for improving hybrid rice seed production yield, its preparation method and application. Background technique [0002] China is a big country of hybrid rice, and at the same time, it is also a big country of hybrid rice seed production. The hybrid rice seed production industry plays an important role in my country's grain production, agricultural population employment, seed trade, and the competition and development of seed companies. At present, the yield of hybrid rice seed production in my country is generally 100-150 kg per mu, and there are few high-yield seed production combinations exceeding 200 kg, and the seed production of some hybrid rice combinations with excellent performance is even below 50 kg. The market promotion of excellent hybrid rice combinations is limited. [0003] Since the research on rice flowering regulators wa...
