1. Crop demand nutrients are comprehensive, trace elements are synergistic, indispensable, but not easy to excess, excessive nitrogen is not resistant to storage and transportation, excessive phosphorus, small fruit, unfavorable color change, will also affect the thickness of the peel, excessive potassium early color change, excessive trace elements lead to poisoning!
2. There will be a fight between many elements, usually we do not need to use a single element, different nutrients are not independently regulated, but through collaborative regulation to achieve the balance of different nutrients of crops, that is, nutrient synergy (1+1>2)!
3. The most important thing is whether we can absorb the fertilizer applied to the soil, or how much the utilization rate is questionable, the biggest impact is the PH value, too acid and alkali are not good, in the past, the fertilizer was used to increase the yield significantly, now there is no more fertilizer, mainly the utilization rate is lower!
4. How to improve the utilization rate of fertilizer, the simple way is to use humic acid to improve the soil water and fertilizer retention capacity, amino acids, seaweed, fungal agents and other roots to promote the improvement of the soil!
5.成功经验，膨果期转色期做到全面均衡营养使用大量元素水溶肥加寡糖钙镁，能满足草莓所有养分需求，而且各种元素搭配相对平衡不浪费，也是我摸索出最好的配方，一组10亩地，回报高！
6. Wrong approach, excessive fertilization, partial fertilization, not paying attention to regulating the soil, too wasteful, heartache!
7. Foliar fertilizer is very important, especially for controlling the vigor, promoting flowering, and swelling is very obvious!
