玉米前期白苗、后期花叶、秃头是缺锌的表现。1982—1983年,我们做了玉米拌种锌肥的试验。第一年在潮土和洪淤黄垆土地试验,增产23.5%;第二年增设了盐碱地(垆土)试验,增产18.9—42.6%。一、试验材料与方法供试玉米品种为中单2号,设拌种与不拌种两个处理,重复5次,随机区组排列,小区面积0.2亩。100毫升水兑2克锌肥,拌玉米种子1斤,凉干播种。管理同大田。二、试验结果与分析锌肥拌种的玉米穗长、穗行数,行粒数、百粒重均优于对照,早熟3—5天,有 Pre-white rice seedlings, late mosaic, bald is the performance of zinc deficiency. From 1982 to 1983, we tested the corn dressing with zinc fertilizer. In the first year, soil and flood silt were planted in land with a yield increase of 23.5%. In the second year, a saline-alkali soil (earth loam) test was added to increase yield by 18.9-42.6%. First, the test materials and methods for the test corn varieties in the single No. 2, set the seed dressing and not mixed seed treatment two, repeated 5 times, randomized block arrangement, the plot area of ​​0.2 acres. 100 ml of water against 2 grams of zinc fertilizer, mix corn seed 1 kg, dry sowing. Management with the field. Second, the test results and analysis Zinc fertilizer dressing corn ear length, the number of rows per ear, grain number, weight per 100 are better than the control, early 3-5 days, there
