1988～1990年期间,在全省不同生态区的马铃薯、甘薯及甜菜上进行试验示范,明确了膨大素对3种作物的处理时间和使用方法。马铃薯种薯块喷雾并闷种24小时比对照增产26.21％,出苗后60～80天喷雾比对照增产10.78～17.61％,切干率(每50公斤鲜薯的烘干重)增加0.56～1.36个百分点,薯干产量提高15.48～34.98％,甘薯生育期喷雾1次比对照增产9.87％,浸根加喷雾增产32.57％;甜菜生长期喷雾较对照增产10～15％,且含糖量增加0.35。经变量分析,达显著或极显著水平。
From 1988 to 1990, experiments and demonstrations were carried out on potatoes, sweet potatoes and sugar beet in different ecological regions of the province, and the treatment time and the use method of three kinds of crops by the bulking elements were clarified. The yield of potato tubers increased by 26.21% compared with the control at 24 hours after spraying and then increased by 10.78 ~ 17.61% at 60 ~ 80 days after emergence. The cutting rate (drying weight per 50 kg fresh potato) increased by 0.56 ~ 1.36 percentage points , The increase of dry matter output was 15.48 ~ 34.98%, the yield of sweet potato was 9.87% more than that of the control one time and 32.57% when the root was sprayed and the spray was increased. The spray yield of beet was 10 ~ 15% higher than that of the control and the sugar content increased 0.35%. By variable analysis, significant or very significant level was reached.
