三亚天涯区南红农场水稻锌肥肥效试验

Effect of Zinc Fertilizer on Rice in Nanhong Farm of Tianya District in Sanya City

为研究在三亚市土壤类型下施用锌肥对水稻的影响,以提高水稻锌含量,本试验设置两个处理,处理1不施锌肥(常规施肥),处理2在处理1的基础上底施ZnSO_(4).H_(2)0_(2).54 kg/667m^(2),每个处理均设置3次重复.测试分析各处理水稻产量、籽粒与茎秆锌含量、水稻养分含量、锌肥的肥料利用率.结果表明:与处理1(不施锌肥)相比,处理2的产量提高4.61%;籽粒与茎秆的全锌含量较处理1差异显著,分别提高180.8%、136.3%;锌肥利用率为31.54%;此外,处理2的籽粒全氮、全钾、茎秆全钾含量相较处理1分别提高了37.5%、39.1%、40.0%.说明施锌肥的处理水稻籽粒与茎秆的锌含量显著增加.

To study the effects of zinc fertilizer application on rice under soil types in Sanya city,and promote the yield of rice in Sanya city.Two different treatments were set up in this study,treatment one was not applying zinc fertilizer(conven-tional fertilization),treatment two was applying 2.54 kg·667m^(-2) ZnSO_(4).H_(2)O on the basis of treatment one,and each treatment was set up three times.Rice yield,grain and stem zinc content,effects of zinc fertilizer on rice nutrient content and fertilizer utilization rate of zinc fertilizer were tested and analyzed.The results showed that compared with no zinc fertilizer,the yield of treatment 2 increased by 4.61%;The total zinc content of grain and stem in treatment 2 was significantly higher than that in treatment 1 by 180.8%and 136.3%,respectively.The utilization rate of zinc fertilizer was 31.54%.In addition,the contents of total nitrogen (N)in grain,total potassium(K)and total potassium(K)in stem in treatment 2 were increased by 37.5%,39.1%and 40%,Under this test conditions,the total zinc content of grain and stem statistically increased.
