叶面喷施锌肥对湘康玉2号产量的影响
|
摘要
为了探明湘康玉2号在慈利县适宜的锌肥施用量,研究采用随机区组试验设计,以喷施清水为对照,比较叶面喷施不同浓度的硫酸锌处理对湘康玉2号产量的影响。结果表明:与对照相比,叶面喷施锌肥对湘康玉2号的生育期没有影响,但是有效增加了玉米的穗长、穗粗、行粒数和百粒重,从而提高单株产量。湘康玉2号的产量随着叶面喷施锌肥用量的增加呈先增加后降低趋势,当锌肥施用量为0.22%时增产效果最显著,增产率达9.29%,具有一定的推广价值。
In order to find out the suitable amount of zinc fertilizer for Xiangkangyu No.2 in Cili County, a randomized block experiment was conducted to compare the effects of foliar spraying with different concentrations of zinc sulfate on the yield of Xiangkangyu No.2. The results showed that foliar spraying of zinc fertilizer had no effect on the growth period of Xiangkangyu No.2, but it effectively increased ear length, ear diameter, grain number per row and 100-grain weight of maize, thus increasing the yield per plant. The yield of Xiangkangyu No.2 increased first and then decreased with the increase of zinc fertilizer application rate. When the application rate of zinc fertilizer was 0.22%, the yield increase was the most significant, and the yield increase reached 9.29%, which had certain popularization value.
