甘蔗是热带、亚热带地区的主要经济作物之一,由于其生育期长、肥料用量大,许多蔗农对甘蔗粗放管理,施肥时间及施肥量更掌握不住,影响产量的提高。现介绍如下几种施肥技术:1、亩产蔗茎5吨,需吸收纯氮(N)10～11.5千克,磷(P_2O_5)7.5～9千克,钾(K_2O)11.5～13.5千克。以有机肥为主,配施化肥。施肥原则为:施足基肥,早施分蘖肥,猛攻伸长肥,适量追施长粗肥,补施壮尾肥。一般亩施纯氮(N)15～20千克,磷(P_2O_5)5～7.5千克,钾(K_2O)5～10千克,其中磷、钾肥宜作基肥、种肥。
Sugarcane is one of the main cash crops in the tropical and subtropical regions. Due to its long growth period and large amount of fertilizer, many sugar cane farmers can not control the extensive management of sugarcane, the time of fertilization and the amount of fertilizer application, thus affecting the yield increase. Here are the introduction of the following fertilization techniques: 1, 5 tons of cane per mu yield, the need to absorb pure nitrogen (N) 10 ~ 11.5 kg, phosphorus (P_2O_5) 7.5 ~ 9 kg, potassium (K_2O) 11.5 ~ 13.5 kg. Mainly organic fertilizer, with fertilizer. The principle of fertilization: Shizujifei, as early tiller fertilizer, fierce extension of fat, the amount of topdressing coarse fat, fill Shi Zhu fat. General Mushi nitrogen (N) 15 to 20 kg, phosphorus (P_2O_5) 5 to 7.5 kg, potassium (K_2O) 5 to 10 kg, of which phosphorus, potassium fertilizer should be used as a base fertilizer, kind of fertilizer.
