1983年连湖农场大面积甜菜单产达到8066斤,部分超过万斤。现就该场甜菜高产栽培技术加以总结。一、选地轮作甜菜的主根入土可达2米,侧根长1米多,是需水需肥较多的作物。过沙、过粘、土层过浅,盐碱过重的田,不宜种植甜菜。甜菜不能“重茬”,重茬地减产30%、含糖率降至13%,连作3年减产54%,含糖量仅有10%。应实行四至五年以上轮作,并注意合理倒茬,以菜地、瓜地或小麦作为前茬比较理想。1980年该场试种甜菜613亩,末重视选地,单产只有3670斤;1981年在麦茬地上种植588亩、单产5182斤;1982年第5生产
In 1983, a large area of Lake Farm yield of sugar beet 8066 pounds, some more than kilos. Now on the field beet cultivation techniques to be summed up. First, the rotation of the main root beet selection of up to 2 meters, lateral root length of more than 1 meter, is the water needs more fertilizer crops. Over the sand, too sticky, too shallow soil, saline-alkali fields, should not be planted beets. Beet can not be “stubble”, crop reduction 30%, sugar content dropped to 13%, even crop 3 years 54% reduction in sugar content of only 10%. Should be implemented four to five years of crop rotation, and pay attention to reasonable stubble, to vegetable, melon or wheat as the former crop is ideal. In 1980, the field planted 613 acres of beets, at the end of the selection, yield of only 3670 pounds; 1981 planted 588 acres of wheat stubble, yield 5182 pounds; 1982 fifth production
