锌是植物不可缺少的微量元素之一。锌素营养状况的好坏,对农作物生长发育影响很大。特别是水稻、玉米、小麦等作物,生长中缺锌时就会引起生理性病害。据调查,近年来我县土壤已程度不同地出现缺锌的症状。为此,我们从1982年开始,连续二年在县良种场,各区、社农技站、组的共15个点,449 .9亩面积上 (锌肥推广面积2995 .5亩),进行施锌试验示范,已初步显示出锌肥的增产效果。一、锌肥试验示范概况 1982年,在县良种场
Zinc is one of the essential trace elements in plants. Zinc nutritional status is good or bad, a great impact on crop growth and development. Especially rice, corn, wheat and other crops, the growth of zinc deficiency can cause physiological diseases. According to the survey, in recent years, the soil in our county has different degrees of zinc deficiency symptoms. To this end, we started in 1982, for two consecutive years in the county seed market, the district, social science and technology station, a total of 15 points, 449 .9 acres of area (zinc fertilizer area of 2995.5 acres), Shi Zinc test demonstration, has shown an initial increase of zinc fertilizer production. First, the Zinc Fertilizer Experimental Demonstration In 1982, in the county seed field
