锌肥对崇明水稻的增产效果研究
Study on the effect of zinc fertilizer on rice yield in Chongming County
摘要
Abstract
According to the second general survey of soil and the survey result of zinc deficiency in paddy field soil in Chongming area,experiments of additional application of zinc fertilizer were carried out in direct-seed rice field and in raising seedlings in trays to study the effect of zinc fertilizer on the rice yield. The multiple location experiments for many years showed that under adequate application rates of N, P and K fertilizers,additional application of zinc fertilizer could improve the agronomic characters,effective tillering and seed-setting rate of rice,and significantly increase the rice yield and economic benefit. Under direct-seed rice field, the optimal application rate of zinc fertilizer was 30 kg/hm2; and under raising seedlings in trays, the optimal concentration of zinc fertilizer solution was 2％. The rice yield increment produced by additional application of zinc fertilizer to direct-seed rice field could reach up to 19.17％ and was higher than that by additional application of zinc fertilizer solution in raising seedlings in trays, but the latter was easier in operation.关键词
