摘要
试验结果表明 :水稻施用有机 -无机复混肥较常规施肥 :(1)每穴增加分蘖 1～ 2个 ,熟期提前 2～ 3d ;(2 )增强了水稻抗倒伏性和田间光能利用率 ,有利于形成高产群体 ;(3)增加水稻穗长、谷草比和单位面积穗数 ,施量 4 0kg/ 6 6 7m2 比常规施肥增产 8.9% ;(4)改善了稻米的加工品质、外观品质和理化性状 。
The result showed that organic-mineral mixed fertilizer can improve yield and quality of rice. Firstly, compared with conventional fertilizers, one or two tillers were increased in a hole and maturity date was in advance of two or three days. Secondly, organic-mineral fertilizer can enhance the resistance of lodging and efficiency of energy conversion and form a high-yielding colony in paddy. Thirdly, with the improvement of spike length, grain to straw ratio and spike number in unit area, yield per unit area of rice was increased by 8.9% under the condition applied amount of organic-mineral fertilizer was 40kg/667m 2. Finally, improving processing and visual quality and physical and chemical property, organic-mineral fertilizer is an appropriate fertilizer for planting excellent rice.
