为探索锌肥在我县滨海淡涂田上的增产效果,1983年,我站在清江公社渡头大队万安塘吴玉龙农户承包的3亩责任田里进行了锌肥对水稻的肥效试验。试验田土壤为浅海沉积物发育的水稻土,质地比较粘重,地下水位较高,pH7.5,亚铁反应和石灰性反应强。以往种植早稻和晚稻僵苗均较严重。试验共分锌肥对连作早、晚稻的肥效以及早稻施用锌肥对后作晚稻的残效三个部分。现将试验结果分述子后。
In 1983, I stood on the 3-mu responsibility field contracted by Wan Yutang Wu Yulong Farmers in Qingjiang Commune to test the fertilization effect of zinc fertilizer on paddy rice. The soil in the experimental field is paddy soil with shallow sea sediments. The texture is relatively sticky, with high groundwater level, pH7.5, ferrous reaction and strong lime reaction. In the past, planting early rice and late rice stiff seedlings were more serious. The experiment was divided into three parts: the effect of zinc fertilizer on continuous and late rice and the effect of zinc fertilizer on late rice for early rice. Now the results of the sub-sub-test.
