摘要
通过不同浓度Cu、Mn、B、Zn和多效唑在马铃薯花蕾期叶面不同浓度喷施结果试验,结果表明:多种微量元素配合对马铃薯的生育性状、生理指标、品质和产量都有明显的影响。随着微量元素用量增加,叶绿素含量和光合速率增加,淀粉含量增加,品质得到改善,产量有明显的增加。微肥处理可提高大中薯率,减少小薯率,提高了商品薯的比率。微量元素和多效唑配合使用,可明显降低植株的株高,茎粗增加,光合速率提高,但对品质没有明显作用。
Different microelements and plant growing regulator（PP333） had been applied to potato leaves in its flowering period. The result showed that ： the coordination of Cu ,Mn, B, Zn play an important role to the growth, Physiological Characteristics and yield of potato. With the increase of microelements amount, the chlorophyll content, rate of photosynthesis, starch content and yield had been increased and the quality had been improved. The coordination dressing of microelements with PP333 could decrease the height of plant, increase stem diameter and rate of photosynthesis, but had no obvious effect to quality.
