为考察腐殖酸和锌在减量施肥条件下对水稻生长和产量的影响,开展了田间小区试验。结果表明:直接减施普通复合肥会造成水稻减产;添加腐殖酸可以缓解水稻减产的程度,且随着腐殖酸添加量的增加,缓解作用增大;在添加质量分数3.0%腐殖酸和0.4%一水硫酸锌、减量施肥10%的条件下,可以获得水稻不减产的效果。
In order to investigate the effects of humic acid and zinc on the growth and yield of rice under the condition of reduced fertilization, a field plot experiment is carried out. The results show that directly reducing the application of ordinary compound fertilizers will cause rice yield reduction, while adding humic acid can alleviate the degree of rice yield reduction, and with the increase of humic acid addition, the mitigation effect increases. Under the condition of adding 3.0% of humic acid and 0.4% of zinc sulfate monohydrate by mass fraction and reducing fertilization by 10%, the effect of no reduction in rice yield can be achieved.
