在生产实践中,农民对微肥有了逐步的认识,但在施肥技术上存在着问题,为了避免滥施、偏施的弊端、现将常用的12种微肥使用量及施肥中应注意的事项做一总结。 一、微肥使用量 (一)锌肥(硫酸锌):碱性肥,适应于任何作物。 1.基施:每亩1公斤;2.带肥下种:每亩250克;3.浸种:用0.02％～0.1％浓度浸泡种子12小时;4.拌种:按每公斤种子5～6克拌水均匀;5.叶面喷施:常量0.1％,每亩约100克,微量0.4～0.5％,每亩约150克。 (二)锰肥(硫酸锰):酸性肥,适应
In the practice of production, the farmers have got a gradual understanding of the micro-fertilizer, but there are some problems in the fertilization technology. In order to avoid the disadvantages of over-exerting and over-exerting, we should pay more attention to the amount of 12 kinds of micro- A summary of the matter. First, the amount of fertilizer (a) zinc fertilizer (zinc sulfate): alkaline fertilizer, adapted to any crop. 1. Basal: 1 kg per acre; 2. With fertilizer under: 250 grams per mu; 3. Soaking: soaking seeds with 0.02% ~ 0.1% concentration for 12 hours; 4. Seed dressing: 5 to 6 Grams of water evenly; 5 foliar spray: constant 0.1%, about 100 grams per mu, trace 0.4 to 0.5%, about 150 grams per mu. (B) manganese fertilizer (manganese sulfate): acid fertilizer, adaptation
