promote rice seed germination and regulate seedling
Plant growth regulators used to promote rice seed germination and regulate seedling growth during this period.
Sodium Nitrophenolate （atonik）
It has the effect of breaking rice seed dormancy and promoting germination and root growth. Using Panpan Industy’s sodium nitrophenolate 3-6 mg/L liquid, soaking the seeds of single-season late rice for 48 hours, the germination rate was increased by 27.3%-31.3% compared with the clear water control, the average number of seedlings per plant increased by 0.26-0.56, the width of the stem base and the white root of the seedlings were increased by 0.26-0.56. The number increases. It can be mixed with some fungicides and insecticides during the soaking process, but pay attention to the dosage.
Triacontanol
If the seeds are soaked with 0.1% triacontanol emulsion 1 mg/L, the early rice is soaked for 48 hours, and the middle and late rice are soaked for 24 hours. After soaking, the germination can be accelerated. After the rice seeds were soaked with triacontanol from Panpan Industry, the germination rate was increased by about 2%, and the germination potential was increased by about 8% compared with the control. (Note: Seed soaking can be mixed with bactericides such as acetylallicin.)
Brassinolide
Seed soaking in a 0.01~0.02 mg/brassic lactone solution for 36 h can enhance germination potential and rate, seed vigor, neat germination, and facilitate later growth.
Gibberellic acid （ga3）
Soak the seeds with a 10-50 mg/L gibberellic acid solution for 24 hours before sowing. The ratio of the solution to the seed volume is 1:0.8. During this period, turning several times can improve the germination rate and germination potential of rice, and promote the germination to be neat.
6-benzylamino-purine 6BA
Dilute 100 times with 2% 6-BA solution, that is, soak seeds with 20 mgL liquid, soak the seeds of early rice for 48 hours, and soak the seeds of middle and late rice for 24 hours, then germination can be promoted. Experiments in Jiashan, Haining, Zhejiang, etc., after soaking the seeds of early rice with 6-BA, the germination rate of the seeds was increased by 5% compared with the control (water treatment), and the germination was fast and neat.It is beneficial to improve the quality of seedlings and enhance the resistance to stress; the effect of preventing and controlling rotten seedlings of early rice is 48%, and the rate of seedling formation can be increased by 21.8%, thereby increasing the yield of early rice in the later stage. (Note: It must be used in strict accordance with the specified concentration, and can be mixed with fungicides.)
