黑龙江省的甜菜生产多分布在西部干旱地区和北部冷凉地区。两大区的自然条件、气候土质差异很大,西部干旱地区积温较高,≥10℃的积温为2400—2800℃,7、8月份平均气温20—23℃,7—9月份昼夜温差在10℃以上,6—9月份日照时数1300小时,降雨量400—500毫米,甜菜生育期可达150天。而北部冷凉地区,积温较低,≥10℃的积温为2200—2400℃,8、9月份昼夜温差大,在11—12℃,降水量在500—550毫米,甜菜生育日数135天左右。由于我省生育期较短,积温不足,采用纸筒育苗移栽技术可提前和延长生育期30—40天,
Beet production in Heilongjiang Province is mainly distributed in the arid areas in the west and cool areas in the north. The natural conditions of both regions have great differences in climate and soil quality. The accumulated temperature in the arid western part of China is relatively high. The accumulated temperature of ≥10 ℃ is 2400-2800 ℃. The average temperature of July and August is 20-23 ℃. The temperature difference between day and night ℃ above, June-September sunshine hours 1300 hours, 400-500 mm rainfall, sugar beet growth period of up to 150 days. In the northern cold area, the accumulated temperature is relatively low. The accumulated temperature of ≥10 ℃ is 2200-2400 ℃. The temperature difference between day and night in August and September is large. The temperature difference between day and night is between 11-12 ℃ and precipitation is between 500 and 550 mm. As a result of the shorter growth period in our province, lack of accumulated temperature, the use of paper tube seedling transplanting technology can advance and extend the growth period of 30-40 days,
