甜菜施氮肥常常是增加产量,降低含糖。生产管理上的策略必须着眼于获最佳产糖量而不是根产量。本研究探讨增加用氮量对提高蔗糖产量,减少茎叶生长和杂质的价值。供试验土地先种玉米消耗尽土壤中的氮。试验地为细沙壤土,三年全氮量为每公 Sugar beet nitrogen fertilizer is often to increase production and reduce sugar. Production management strategy must focus on the best sugar yield rather than the root yield. This study explored the value of increasing nitrogen use to increase sucrose yield and reduce stem and leaf growth and impurities. The first type of corn for test land depleted nitrogen in the soil. Test for the fine sandy loam, three years of total nitrogen for each public
