Embodiment Construction

[0010] Referring to Figure 1, according to the aforementioned technical solutions, use the "Aiduoshou" 10ml packaging solvent produced by Asahi Chemical Industry Co., Ltd. in different stages of rice hybrid seed production, and the spraying concentration of hybrid rice seed production in different growth and development stages As follows: Seed soaking: Soak seeds with 6000 to 7000 times for 12 to 24 hours; Seedling raising: Spray 5000 to 6000 times at the 2.5-3.0 leaf stage of seedlings; 1-2 stages of young ear differentiation: Spray 4000 to 5000 times; Young ear differentiation 5 -6 stage: Spray 3000 to 4000 times; from the earing stage to the beginning of the earing stage: spray 2000 to 3000 times; from the end of the full ear to the early filling stage: spray 2000 to 3000 times; from the end of the filling period to the early ripening stage: spray 5000 times to 6000 times.

[0011] The effects and effects of the spraying concentration used in the above spraying period on ri...

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 a plant growth regulator in 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 production is the fou...
