九三垦区气候条件对甜菜生长和糖分积累有利,是黑龙江省著名的高糖区。但含糖波动幅度较大。1991年10～11月份菜丝含糖仅14.3度,比1985～1991年平均含糖还低1.9度。含糖高低是诸因素造成的,这里仅从品种、栽培技术方面对低糖原因做以浅析。一、低糖原因。1.种植密度不足,单株营养面积大,造成个体过大,含糖率下降。据调查,尖山农场3队在同一地块
The climate conditions of Jiusan Reclamation Area are good for beet growth and sugar accumulation, and are the famous high-sugar areas in Heilongjiang Province. However, the volatility of sugars larger. From October to November 1991, the sugarcane sweetener only 14.3 degrees, 1.9 degrees lower than the average sugar content of 1985 to 1991. The level of sugar is caused by various factors, here only from the species, cultivation techniques to analyze the causes of low sugar. First, the reasons for low sugar. 1 planting density is not enough, single plant large area of nutrition, resulting in individuals too large, the sugar rate decreased. According to the survey, Jianshan Farm 3 teams in the same plot
