2022年t．The main results were as follows： 1．The effect of storage on the seed of maize under different temperatures
No differences in CK after the contrast experiment of new maize seed dressing of maize seeds and seed germination rate，root length and seedling length．According to the measured data and comparing significant differences among processing data， there was no big difference on seed germination rate，root length and shoot length of after new maize seed mix and CK，and the overall results showed consistently，Can draw new maize seed coating on maize seeds phytotoxicy conclusion．At the same time comparison experiment in 1 0 DEG C，1 5 DEG C and 20 DEG C temperature
stored for 2 months after the new seed dressing of maize seed in germination rate，root length and differences in seedling length and data processing showed that the storage temperature was 20 DEGC when maize seed germination rate，root length and
seedling length ratio under 10 DEGC storage ofmaize seed of7．5％higher，and
1．29cm 0．92cm，than in 1 5 DEGC storage of maize seed 0．5％，0．5 cm and 0．59cm， Can be to get by new type of maize seed coating agent in 20 DEG C storage of maize seed growth better promoting effect．

2．Comparison of different years maize seed
The test compared Lu’an，Rui Sheng，Manshuai，Nongda No．1 and Nongda No．2 seed coating agents which used to Longping 206 maize seed production in 20 1 4 and 20 1 2 with the impact of the germination rate，plant height and the dry weight and SO on．Obtained a conclusion that on maize growth and development will be different
through the use of different maize seed agents to maize seed coating treatment．Using different maize seed agents to 20 1 4 maize seed，it is higher than 20 12 maize seed with
