水稻产量和施肥效果差异—以吉林省为例
Difference of Yield and Fertilization Effect of Rice the Case of Jilin Province
摘要
Abstract
In order to investigate the difference of yield and fertilization efficiency of rice in different cities of Jilin Province,field experiments of soil test and formulated fertilization project from 2005 to 2013 were carried out with typical types of rice in Jilin Province to analyze the effect of increasing yield and nitrogen fertilizer efficiency on rice yield in different cities with three treatments:no fertilizer (N0P0K0),only phosphorus and potassium fertilizer (N0PK) and balanced fertilizer (NPK).The results showed that the rice yields of different cities had remarkable differences,which ranged from 4.0 t · hm-2 to 7.8 t · hm-2 when there was no fertilizer application;increasing yield rates with N0PK treatment and NPK treatment were 10.3％ ～ 30.4％ (except for Liaoyuan) and 35.4％ ～ 109.0％,respectively.Fertilizer application had notable increasing yield effects for Jilin and Changchun,and nitrogen fertilizer significantly affected rice yield for Tonghua and Yanbian.Nitrogen use efficiency in Jilin Province was 16.4％ ～ 32.7％,and was higher in Jilin and Siping;partial fertilizer productivity of nitrogen was 52.5 ～ 76 kg· kg-1 in Jilin Province and that was the highest in Songyuan.Jilin Province was divided into three fertilization regions of west region,middle region and east region according to soil basic physical and chemical characteristics,yield and fertilizer use efficiency.Therefore,balanced fertilization is the best fertilization way to increase rice yield.Moreover,to setup fertilizer partition on the basis of the differences of soil fertility,rice yield and fertilizer use efficiency of different regions and to optimize fertilizer rate are an effective way to realize precise fertilizer and improve the rice yield and fertilizer effect.The study provides a theoretical basis and practical guidance for the high yield of rice and high efficiency management of fertilization in different cities in Jilin Province.关键词
