摘要
在张家港市开展6组水稻不同用量锌肥试验。结果表明:增施锌肥能显著提高水稻产量,且对穗数、结实率、千粒重等产量构成要素均有显著效果。增产效果水稻土高于潮土、低有效锌含量田块高于高有效锌含量田块。锌肥适宜用量为22.50~30.00 kg/hm^2,水稻产量8 890~8 988 kg/hm^2,水稻效益7 282.5~7 589.0元/hm^2。
The experiment of different dosage zinc fertilizer in 6 groups on rice was carried out in Zhangjiagang City.The results showed that the application of zinc fertilizer could significantly increase rice yield and have significant effcet on panicle number,seed setting rate,grain weight and other yield components. Yield increasing effect of paddy soil was better than fluvo aquic soil ,low zinc content is higher than that of field plots with high zinc content. The suitable dosage of zinc fertilizer was 22.50-30.00 kg/hm^2, the rice yield was 8 890-8 988 kg/hm^2,and rice efficiency was 7 282.5-7 589.0 yuan/hm^2.
