Study On The Effect Of Corn Seed Coating

This experiment investigates Yuyu 22 corn seed,Xinong seed film coating,and Beinong seed film coating;also investigates the effects of two seed film coating on percentage germination,shoot height and physiology of Yuyu 22 corn seed;investigates field seeding emergence,shoot height,production and seed equality after harvesting in the field.Lastly,the author researches the effects of seed film coating and different pesticide on field seeding emergence,growth and production of corn seed.The results indicate that there is no difference between the effects of two seed film coatings and control on percentage germination,germination index of Yuyu 22 corn seed in the carriage with light culture.As for the Xinong seed film coating,the vigor index,vigorous seed percentage,shoot height,leaf number,and root number are 107.1.93.3.11.0cm.4.9.2.8cm.3.5,As for Beinong seed film coating,the results respectively are 108.4.92.7.11.5cm.5.2.2.7cm. 3.8.The results are better than control.As for two seed film coatings,the root respectively is 4.5cm.4.2cm.The abnormal seeding percentage is 0.9.1.3.These results are also lower than control,but no difference between Xinong seed film coating and Beinong seed film coating.In field,the results indicate that the field seeding emergence for Xinong seed film coating and Beinong seed film coating are 93.3.91.0.The stand establishment are respectively are 94.0.91.0.The results are better than control.Every 10 days,after field seeding emergence about 20 days,the effects of two seed film coatings on leaf number,root number and shoot height are better than control,but there is no difference two seed film coatings and control in the period of drawing out tassel,flowering and spinning,but respectively are earlier than control about 1.6d.1.7d,and 1.3d.2.5d.The results is advantageous to gross culture and early-maturing,also is earlier than control about 2d.There is no difference two seed film coatings and control in the length of tassel,line number in the every tassel,but respectively is higher than control,about 0.9cm.0.7cm,and 08cm.1.0 cm.Line number of every tassel,one thousand of grain,grain emergence,the production of small area and discount in one acreage are better than control.The production of small area and discount acreage are higher than control about 1.1kg.1.08 kg,and 21.1kg.19.5kg.After using the seed film coating,can improve the equality,color,weight,germination of seed,remarkably decrease the occurring frequency of underground pest.Ostrinia furnacalis(Guenee).Aphid.Exserohilum turcicum. Pythium sp.The Beinong seed film coating is better than the Xinong seed film coating,but no difference.Using the different pesticide,The Beinong seed film coating can also improve the percentage of emergence of Yuyu 22 corn,and prevent occurring disease and pest,enhance length and improve seed production.By contrast,considering use value and decreasing prime cost,using seed film coating with 1 to 50,haue better field use value...
