氮、磷、钾是甘蔗生长发育的三种重要营养元素。其中氨素的营养作用容易表现于甘蔗生长的外观,其增产作用也很大,所以易引起人们的重视。习惯上所谓甘蔗的“缺肥”、或“增产”也常与氮肥的丰歉相提并论,足见氮肥对甘蔗生产的重要性。然而磷肥的作用也不少,它有促进甘蔗幼苗的生长、增加分蘖、伸长节间、增加叶面积、扩大根系的吸收面,从而达到增产蔗茎的作用;磷素还有促进甘蔗成熟、提高早期甘蔗蔗糖份和蔗汁含磷量,有助于制糖工艺过程的澄清,从而提高甘蔗产糖率。可见,甘蔗配施磷素对工、农生产都是有利的。
Nitrogen, phosphorus and potassium are three important nutrients for the growth and development of sugarcane. Nutrient effects of ammonia which is easily manifested in the appearance of sugar cane growth, its production is also a large increase, it is easy to arouse people’s attention. The habit of so-called sugarcane “lack of fat,” or “yield” is often compared with the apology of nitrogen fertilizer, which shows the importance of nitrogen fertilizer on sugar cane production. However, the role of phosphate fertilizer is not less, it has to promote the growth of sugarcane seedlings, increase tillers, elongation internodes, increase leaf area, expand the absorption surface of roots, so as to increase the yield of cane; phosphorus also promote sugar cane maturation, Improve early sugarcane sugar content and sugarcane juice phosphorus content, help clarify the process of sugar, thereby increasing sugar cane yield. Shows that sugar cane with phosphorus on the workers, agricultural production is favorable.
