Effects Of Different Amendments And Planting Methods On Sugar Beet Growth In Saline Alkali Soil

Beet is one of the main raw materials for sugar production in China.Inner Mongolia is one of the three major sugar beet production areas in the country.Liangcheng County of Wulanchabu is one of the important beets in Inner Mongolia.This paper focuses on the cultivation methods,planting density,different saline-alkali soil amendments,and the amount of modifier used in the production of sugar beet field in saline land in Liangcheng County.A total of four experiments were conducted:experiment one,comparative study of tube nursery seedling transplanted film planting and paper tube nursery seedling direct seeding;experiment two,comparative study of different planting densities;experiment three,effects of four modifiers on beet plantation in saline-alkali land and economic benefit analysis;experiment 4,the effect of different dosages of Formula 1 modifier(desulfurized gypsum:humic acid=3:1)on saline land beet.Through investigation and analysis of the main growth dynamic indexes,yield and sugar content of sugar beet in four periods,the following conclusions are drawn:1.Haofeng's soil conditioning agent had the best effect.Sugar beet yield was11310kg/hm~2 higher than that of the blank control,and the yield increase rate was21.11%.The economic benefit of formula 1 was greater than that of Fufeng soil conditioner,and formula 1 was better than blank control.The income increased by4467.1 yuan/hm~2,the increase rate was 17.21%,and the Fengfeng soil conditioner increased by 3494.7 yuan/hm~2 over the blank control,with an increase rate of 13.47%.2.From the perspective of economic efficiency and environmental protection,the benefit is the highest when 200 kg of formula 1 improver is applied per mu,which is 4705.2 yuan/hm~2 higher than the blank control,and the increase rate is 17.75%.3.The paper tube nursery transplanted film has obvious advantages over the paper tube nursery direct seeding,and the indexes of plant height,leaf area index and dry matter quality are all significantly improved.The yield is increased by 9447kg/hm~2,the increase rate is 15.57%,and the sugar content is increased by 0.74%,but the difference is not significant.4.The yield is the highest when the plant spacing is 30cm on the basis of a row spacing of 50cm,that is,when the planting density is about 66667 plants/hm~2,the yield is 62655kg/hm2,and the sugar content is also kept at a high level,the rate of sugar is 15.06%.
