作者于东北农学院学报1978年第3期(内部发行)报导了1977年增甘磷对甜菜催熟增糖效果的试验。为进一步验证其对块根,茎叶产量和含糖率的效应,1978年进行了重复试验,并增加了高氮条件下喷施增甘磷的处理。鉴于增甘磷研制已转入中试阶段,于1979年进行了增甘磷药效的生产鉴定试验。现将试验结果一併报告如后。 The author reported in Northeast Agricultural University in 1978 No. 3 (internal distribution) reported in 1977 increased Gan phosphorus phosphorus in sugar beet ripening test. In order to further verify its effects on tuber, stem and leaf yield and sugar content, repeated tests were carried out in 1978 and the treatments with increasing phosphorus were added under high nitrogen conditions. In view of Gan Gan phosphorus development has been transferred to the pilot stage, in 1979 Gan Gan phosphorus efficacy of the production appraisal test. The test results are reported later.
