苏北滨海地区属暖温带气候。年平均温度13℃,无霜期218天,秋季晴朗凉爽,昼夜温差大。年日照2,278—2,314小时,年降水量934—976毫米,土壤为滨海盐碱土,酸碱度(PH值)为8—8.2。经二十余年脱盐改土,现大部分土地为轻碱土,土壤质地为重粘性土和部分粘砂土。 上述气候与土壤条件基本适于甜菜生长。东辛农场1971年试种甜菜以来,产质量逐年提高。71年亩产块根275斤,含糖率16%;77年4,O00亩甜菜,亩产块根1,876斤,含糖率18.5—19%。小糖厂加工期达5个月。因此,苏北滨海地区,若能根据自然特点,土壤条件和耕作轮作制度的要求,采取综合的高产栽培技术措施,发展甜菜生产的前景是十分广阔的。
North Jiangsu coastal area is a warm temperate climate. The average annual temperature of 13 ℃, frost-free period of 218 days, sunny autumn cool, large temperature difference between day and night. The annual 2,278-2,314 hours of sunshine, the annual rainfall of 934-976 mm, the soil is coastal saline soil, pH (PH value) of 8-8.2. After more than 20 years of desalination and soil improvement, most of the land is now lightly alkaline, with heavy clay and some sticky sand. The above climate and soil conditions are basically suitable for sugar beet growth. East Xin farm since 1971 planted beet, the quality of production increased year by year. 71 mu of tuber root 275 kg, sugar content 16%; 77 years 4, O00 acres of sugar beet, 1,876 pounds per mu root tuber, sugar content 18.5-19%. Small sugar factory processing period of 5 months. Therefore, the coastal areas of northern Jiangsu should have comprehensive high-yielding cultivation techniques and measures based on their natural characteristics, soil conditions and crop rotation system. The prospects for developing beet production are very broad.
