在黑龙江省西部松嫩平原上分布着大面积的碳酸盐黑土,自五十年代中期开始试种甜菜以来,这里已初步形成了我省制糖工业原料生产基地。多年的科研试验结果和生产实践经验表明,甜菜是需肥量最多的作物,每生产一吨甜菜块根约需4.5公斤氧,1.6公斤五氧化二磷和5.5公斤氧化钾,因此,施肥是甜菜获得丰产的物质基础。对于甜菜的施肥技术,我们曾设试验区在碳酸盐黑土上进行了田间试验,现根据我们的田间试验结果和有关科研单位在安
A large area of carbonate black soil is distributed on the Songnen Plain in the west of Heilongjiang Province. Since the start of beet trial in the mid-1950s, a raw material production base of sugar industry in our province has been initially formed here. Many years of scientific research and practical experience have shown that sugar beet is the most needed fertilizer and requires about 4.5 kg of oxygen, 1.6 kg of phosphorus pentoxide and 5.5 kg of potassium oxide per tonne of beet root. Therefore, High yield material basis. For beet fertilization technology, we have set up a pilot area in the carbonate black soil field trials, are based on our field test results and the relevant scientific research units in the security
