Selection Of High-quality Waxy Maize Varieties,quality Analysis And Cultivation Technology Research

At present,people’s life is getting better and better,the requirements for diet structure and food taste are getting higher and higher,fresh waxy corn because of its smooth taste,sticky and delicious characteristics,gradually into the public vision,become a delicacy on the table,planting area is also increasing.However,there are many kinds of waxy corn,requiring higher planting technology and scientific fertilization treatment,many farmers lack relevant planting experience,do not master the corresponding supporting planting technology of new varieties of waxy corn,so that the yield of fresh waxy corn is low,the economic benefits are reduced,so it is necessary to increase efforts to promote supporting cultivation technology,improve the yield of fresh waxy corn,and ensure the quality of fresh waxy corn.In this paper,Jinuo 34 was used as the experimental material to study its supporting cultivation technology.In this paper,the yield traits,phenological period,ear traits and field resistance of 14 different waxy maize varieties were compared,and the excellent waxy maize variety Jinuo 34 was screened,and it was found that it could achieve higher yields and show higher resistance and quality when planted in this region.In the second year,using Jinuo 34 as the test material,the planting density and topdressing nitrogen fertilizer test and the growth dynamic test of the plant were tested,and the following test conclusions were made:(1)Results of screening test of new waxy maize varieties: Fuljin Nuo 976,Wannuo 2017 and Jinuo 34 are recommended to continue to promote planting in Jilin Province due to their high fresh ear yield and good field traits;However,the fresh ears of Huangjiao No.1,Tonggluo No.3,Tonggluo No.1,Starglut 44 and Jinong Nuo No.8 have low yields,and the field characteristics of Nuo 1607,Zhonggluo 336,Jiuhuo No.6,Jingke Nuo 617 and Jinong Nuo No.25 are average,and it is not recommended to continue to promote planting.(2)Experimental results of planting density and topdressing nitrogen fertilizer of Jinuo 34:With the increase of nitrogen application level,there was a trend of extension in each growth period of waxy maize.The planting density and fertilization amount do not affect the fresh food quality of waxy maize.The optimal planting density of Jilin Province was 60,000 plants/hm2,and 300 kg/hm2 of nitrogen fertilizer was topdressed.The yield traits under each density treatment and each topdressing treatment were very different,and the yield traits under the combined effect of the two were very significant.(3)The results of the dynamic growth test of Jinuo 34 plants: the plant stem thickness,plant height,dry matter weight,fresh hundred grains,leaf number and crude starch content of fruit ear grain showed "S" type linear changes in Jinuo 34;Before and after the corn flour period,the leaf area index of maize plants changed greatly.The water content of grain showed a gradual decrease with the extension of the growth period.The content of crude starch showed a gradual increase with the extension of the growth period.The soluble sugar content,grain filling rate and protein content all showed parabolic changes.
