摘要
通过盆栽对比试验进行施用化肥和腐殖酸复合肥不同用量对水稻产量及品质的影响研究。结果表明:在一定的用量范围内,水稻的株高、分蘖数、生物产量和籽粒产量都以腐殖酸复合肥处理最高;超过适宜用量时,均呈现降低趋势。等养分含量条件下,腐殖酸复合肥水稻籽粒中淀粉、蛋白质含量均高于化肥。施用腐殖酸复合肥水稻籽粒中淀粉含量和产淀粉量均以FM4处理最高;施用化肥其含量均以HF4处理最高。施用腐殖酸复合肥水稻籽粒蛋白质含量以FM2处理最高,产蛋白质量以FM4处理最高;化肥处理中均以HF3处理最高。从提高水稻籽粒产量和品质角度来说,腐殖酸复合肥处理FM3,每盆施用20 g为最佳施肥方案。过量施用含腐殖酸的肥料会抑制水稻的生长,降低氮磷钾肥料的作用。
The effect of different amount of chemical fertilizer and humic acid compound fertilizer on rice yield and quality were studied by pot experiment. The results showed that： In the framework of a certain amount of rice plant height, tillering number, biological yield and grain yield were the highest humic acid compound fertilizer processing; more than appropriate amount of time showed a decrease. Nutrient content in the same conditions, humic acid compound fertilizer in rice grain starch, protein content is higher than the chemical fertilizer. Application of humic acid compound fertilizer in rice grain starch content and starch production volume in order to deal with the highest FM4 ; application of chemical fertilizers are the highest HF4 deal. Application of humic acid compound fertilizer in rice grain protein content to FM2 the highest quality protein production to the highest FM4; fertilizer processing HF3 are the highest. Improve rice grain yield and quality point of view, application 20 g/pots humic acid compound fertilizer is the best Fertilization program. Excessive application of fertilizers containing humic acids inhibit the growth of rice, reduce the role of nitrogen, phosphorus and potassium fertilizers.
