摘要
研究硫酸锌在不同土壤类型、施锌量、稻作类型和施用方式下的施用效果。结果表明,施用硫酸锌可提高水稻抗逆性,增产效果明显,施用硫酸锌产量平均为460.96kg/666.7m2,比对照增产35.23kg,增加8.28%,纯增收37.46元。不同土壤类型增产效果不同;水稻硫酸锌最佳经济施用量为1.1kg/666.7m2;稻作类型以早稻优于单季稻,单季稻优于双季稻;施用方式以基肥优于追肥。
Experiments of the effects brought by fertilizing ZnSO4 in different types of soil,to different types of rice and in different ways of fertilizing have been made.The results show that ZnSO4 can improve the rice ability to resist drought and coldness with an evidently increased production of 460.96kg/666.7m2 at an average level.In contrast to that before fertilizing ZnSO4,the production has increased by 8.28% ,equally to $ 35.46.Usually the increase in production varies with the different types of soil.The best application of ZnSO4 to rice is 1.1kg/666.7m2.The early season rice is superior to the single cropping,also the single cropping of rice is superior to the double cropping.For the ways to applying fertilizer,the base manuare is better than the top application.
