| 摘 要： | 以甘蔗品种粤糖00-236为试材,通过盆栽试验,研究了在滴灌施肥条件下钾肥施用分配比例对甘蔗产量和品质的影响。结果表明,在总施钾量相等时,甘蔗不同生长期钾肥分配比例的不同对甘蔗伸长速度、蔗茎产量、干叶重的影响均表现为差异不显著;钾肥施用量不同分配比例中,22.5%~55%~22.5%、30%~50%~20%、20%~60%~20%1、0%~60%~30%四种钾肥分配方式更有利于提高甘蔗蔗糖分、蔗汁蔗糖分和蔗汁锤度。因此,在甘蔗水肥管理中,应注重中、后期的钾素供应,以利于甘蔗糖分的积累和品质的提高。 |

| Abstract: | A pot experiment of planting sugarcane YZ00-236,designed to have nine treatments on varying time distribution potassium application under drip fertigation,was carried out to evaluate the effects of these treatments on the growth,yield and quality of sugarcane.The results showe that on the condition of equal total potassium application,there had no influenced significantly on growth speed,cane yield and total leaf dry matter under different treatment.With the distribution ratio of potassium in seeding and ti... |
