不同肥料种类对水稻强化栽培产量及稻米品质的影响

Effect of Different Kinds of Fertilizers on the Yield and Grain Quality in the SRI

通过水稻强化栽培技术中使用不同种类的肥料比较,试验得出:在氮、磷、钾用量相同的情况下,均能提高水稻的分蘖数,其最高分蘖数和成穗率以及增产效果均以“微生物活性肥+有机肥+化肥”的处理最高。施用不同种类肥料对稻米品质的影响各不相同,施用有机肥可提高稻米的加工品质和降低垩白粒率、垩白度,有机肥与化肥配合施用能降低稻米的直链淀粉含量。有机肥、化肥和微生物活性肥料进行合理的搭配使用,比单一施用一种肥料能够更明显地提高水稻产量,改善稻米品质。

By the way of using different kinds of fertilizers in the system of rice intensification,the results have showed: under the same condition of cultivation and management, All fertilizers can enhance the number of tillering of rice. The number of tillering in rice of maximum is treatment 3(organic fertilizer). Maximum effective tiller rate is treatment 6(microbes activity fertilizer+organic fertilizer+fertilizer). The root activity of treatment 6 is the highest on heading stage of rice,,the grain yield of treatment 6is higher than other treatments. Using different kinds fertilizer, the effects of grain quality are different under SRI condition. By applying organic fertilizer, it can improve machining quality of rice (especially increase milled rice and head mill rice.) and decrease the percentage of chalky kernel and chalkiness. It can decrease amylose content of rice that organic fertilizer coordinate using fertilizer. It was obvious to improve grain quality that organic fertilizer coordinated using fertilizer or microbes activity fertilizer coordinated organic fertilizer and fertilizer.
