Effect Of Different Planting Ways, Density And Fertilization Amount On Yield And Sugar Content Of Sugar-beet

A series of studies about planting ways, density and fertilization amount is carried out in this paper, agronomic and economic traits of Sugar-beet were investigated and researched in different period, reasonable planting ways, density and fertilization were obtained.The results show that:1. Under the conditions of climate and soil in Qitai County, Xinjiang, the Sugar-beet HI0936 is used as test material. Agronomic and economic traits in both planting mulch relative to live in open field has obvious advantages, The output of mulch cultivation is higher than the outdoor live broadcast 8676.64kg/hm2, live in sugar content is lower than outdoor 0.55 degrees, in terms of sugar yield higher than outdoor live broadcast of 817.17kg/hm2, overall performance is superior to the open country live cropping pattern. Therefore, to obtain high yield in the area, plastic mulching technology is one of the better choice.2. Different planting density on the base of sugar beet plant height of dry matter accumulation Leaf area index, stem diameter has a certain influence, the indicators change over the density. Based on the different development stages of the different planting density treatment of Foliage height, dry matter and cluster height Comparison of leaf area index, by comparison, The density effect is best when about 90000 plants/hm2, the planting density of sugar beet production is highest, to 90978.30kg/hm2, sugar content reaches 15.07%.Therefore, the planting density of 90000 plants/hm2 is optimum density.3.On the basis of drip irrigation using lime better beet special fertilizer, the density test is designed six fertilizer treatments and a blank control.Test the following conclusions:Fertilizer has a great role in promoting on the growth of the plant, the output of the fertilizer treatments were higher than control, the yield of the fertilizer treatments were higher than the black control. Reach on Foliage height, rhizosphere, leaf number, root-shoot ratio, chlorophyll content, dry matter and leaf area index found that in dealing with a 0-100kg/mu (0-1500kg/hm2) of this range, sugar beet yield and root fresh weight per plant.Have a significant positive correlation with the fertilizer rate.Between sugar content and fertilizer have a significant negative correlation. Sugar content to a minimum when the fertilizer rate increase to F. Sugar beet root yield reached the maximum. When fertilizer rate in the 60 kg/mu (900kg/hm2), subsequently fallen slightly,Considering yield and sugar content, the best dosage of Laimujia fertilizer is 60 kg/mu (900kg/hm2).
