近年来,由于土壤微量元素养分供应不足,往往引起一些作物生理病害,或因潜在性缺乏影响农产品质量,造成减产。缺锌症状在某些作物上表现得更为明显,已成为持续增产的限制因素。如小麦、玉米等对锌表现得就比较敏感,可见,开展锌肥应用前景的试验研究,对促进我省农业发展具有十分重要意义。为此,按照国家经委、农牧渔业部的安排部署,由省农牧厅和农科院共同组成协作组,从一九八○年开始,先后在五十多个县、一百四十多个试点,着重就锌肥在小麦、玉米及水稻、芝麻、谷子、大豆等作物上进行了肥效、施用方法、用量、时期的 In recent years, due to lack of nutrient supply of soil trace elements, some crop physiological diseases are often caused, or the potential lack of quality affects the quality of agricultural products, resulting in reduced production. Zinc deficiency symptoms are more pronounced on some crops and have become the limiting factor for continued productivity gains. Such as wheat, corn and other performance of the zinc is more sensitive, we can see that the application of zinc fertilizer prospects for the study of the promotion of agricultural development in our province is of great significance. To this end, in accordance with the arrangements made by the State Economic Commission, the Ministry of Agriculture, Animal Husbandry and Fisheries, the Provincial Department of Agriculture and Animal Husbandry and the Academy of Agricultural Sciences jointly formed a collaborative group that started in 1980 and has served more than 50 counties and over 140 A pilot, focusing on zinc fertilizer in wheat, corn and rice, sesame, millet, soybeans and other crops on the fertilizer, application methods, dosage, period
