Embodiment Construction

[0010] Referring to Fig. 1, according to the aforementioned technical solutions, the spraying concentration is as follows for the different growth and development stages of hybrid rice seed production: soaking seeds: soaking seeds with 6000 to 7000 times for 12 to 24 hours; raising seedlings: at the 2.5 to 3.0 leaf stage of seedlings, Spray 5,000 to 6,000 times; Spray 4,000 to 5,000 times for the 1st and 2nd stages of young panicle differentiation; Spray 3,000 to 4,000 times for the 5th to 6th stage of young panicle differentiation; times; from the end of full ear to the beginning of filling: spray 2000 to 3000 times; from the end of filling to the early stage of wax ripening: spray 5000 to 6000 times.

[0011] The effects and effects of the spraying concentration used in the above spraying period on rice seed production are: Seed soaking: promote seed germination and rooting, improve seed germination rate and seedling rate; seedling raising: increase root, tiller, and stem bas...

Abstract

A method for applying the plant growth regulator "Aiduoshou" to produce hybrid rice seeds for improving quality and increasing yield to optimal effect is disclosed, and it features that it is dissolved in solvent with different proportions for different stages of rice growth.

Description

technical field [0001] The invention relates to a method for using a plant growth regulator, and further refers to a method for using the "Aiduoshou" plant growth regulator to spray hybrid rice seed production. Background technique [0002] "Aiduoshou" is an epoch-making high-tech product of Asahi Chemical Industry Co., Ltd. in Japan. It was officially registered as a plant growth regulator in the Ministry of Agriculture of China in December 1992 (PD165-92). Over the past few years, the company has guided farmers in our country to use the product with "How to Use the Epoch-making New Pesticide "Aiduoshou"" (hereinafter referred to as "Use Method"). However, the problems in this "Method of Use" are: ① only 66 kinds of crops are used, which is very incomplete. Among them, there are many small crops and few large crops, which does not conform to the actual situation in China. Especially because China is the kingdom of rice, the birthplace of hybrid rice, and hybrid rice seed p...
