马铃薯硼肥肥效试验研究

An Experiment on Effect of Boron Fertilizer on Potato

试验研究了硼肥不同施用量和不同施用方法对马铃薯产量、马铃薯块茎淀粉含量以及块茎剖面特征的影响。结果表明:基施硼肥9.0、18.0 kg/hm2,追施(喷施浓度0.10%)硼肥均有利于植株对土壤0～20 cm氮、钾肥的吸收;旋耕撒施硼肥18.0 kg/hm2作基肥,对提高马铃薯单株产量有一定作用,较不施硼肥处理增产4 375.5 kg/hm2,增产18.99%。

An experiment was made on the effects of different application amount and different application methods of boron fertilizer on the yield of potato,the starch content and the profile feature of potato tubers.The result showed that the base boron fertilizer of 9.0 and 18.0 kg/hm2 and the topdressing（concentration 0.10%） boron fertilizer were beneficial to the plant’s absorption of nitrogen and potash fertilizer in 0 ~ 20 cm soil.The rotary tillage application of boron fertilizer 18.0 kg/hm2 as base fertilizer had certain effect on upgrading the single plant yield of the potato with a 18.99% increase of the yield,namely 4 375.5 kg/hm2 compared with the control.
