为探讨甜菜高产栽培途径,1987年于黑龙江省肇州县双井村进行了甜菜大城双行栽培试验,试图从提高亩保苗株数入手,以获甜菜高产高糖。试验地为碳酸盐黑钙土,前茬小麦,伏翻,春整地,春起垅。氮磷肥一次性施入,比例为1:2(纯氮5公斤,纯磷10公斤)。亩施锌肥2公斤,硼砂50克,稀土40克。试验设6个处理,即:①90厘米宽垅,双行,不覆膜; In order to explore the ways of high-yielding sugarbeet cultivation, we conducted a double-row cultivation experiment of sugar beet in 1987 in Shuangjing Village, Zhaozhou County, Heilongjiang Province. Test for the carbonate chernozem, wheat crop before, volt turn, spring preparation, spring 垅. Nitrogen and phosphate fertilizer applied once, the ratio of 1: 2 (5 kg of pure nitrogen, pure phosphorus 10 kg). Km 2 kg of zinc fertilizer, 50 grams of borax, rare earth 40 grams. Experiment set up six treatments, namely: ① 90 cm wide 垅, double line, not covered;
