摘要
甜菜大垄栽培垄高沟深,有利于调节土壤水分、降低土壤容重、增加土壤孔隙度、改善土壤的物理性状.垄距为99cm双行种植能够提前播种期和提高苗期土壤地温.比单行种植增加密度20％,增强了光合作用的能力.促进植株生育。提高块根产量24.3％、含糖率0.2度、产糖量25.6％.经济效益较好。
The cultivation in high ridge wide row in very favourable for regulating coil moisture, decreasing the volume weight of soil, increasing the soil porosity and improving physical characters, because the row ridge is very high and the ditch very deep. When the row space at 99 cm and double lines in a row the sowing dates could be in advanced, and the soil temperature could be increased in seedling stage, the plant density increased 20% than single line in a row, photosynthesis increased, promoting the growth of sugarbeet, root yield increased 24.3%, sugar content 0.2%, sugar yield 25.6% and got better economic benefits.
