马铃薯微肥拌种与叶面喷施增产效果的研究

为探讨马铃薯高产栽培中的配套措施,试验筛选并研究了两种微肥在马铃薯种植上进行拌种与叶面喷施试验。结果表明:微肥拌种与叶面喷施有利于种薯切块后伤口愈合,能提前出苗、开花,缩短生育期,提高大薯率,增产明显。大西北牌多元微肥拌种与叶面喷施每667 m2增收251.9元,稀土旱地宝增收210.1元。

Increasing Potato Yield by Seed Dressing and Foliage Application of Trace-element Fertilizer

Two trace-elements fertilizers,"Daxibei" multi-trace-elements fertilizer and rare earth "Handibao",were used in seed dressing and foliage application in this research in order to investigate their effects on potato yield.The fertilizers used in seed dressing and foliage application benefited potatoes on wound healing of cut seeds,early emergence and flowering,shortening the growth duration,increasing the large percentage of large and medium-sized potato tubers,and increasing the yield.On the basis of 667 m2 of land,"Daxibei" multi-trace-elements fertilizer used in seed dressing and foliage application increased the income by 251.9 Yuan,while for rare earth "Handibao",the income increase was by 210.1 Yuan.
