65,438+0. From planting to flowering, the absorption of nitrogen, phosphorus and potassium accounted for 20%, 65,438+06% and 65,438+04% of the total absorption in the whole growth period, respectively.
2. The first, second and third inflorescences are the first peak of strawberry production from flowering to fruit expansion and maturity, accounting for more than ss% of the total output and absorbing more nutrients;
3. The second peak of strawberry fertilizer absorption is from the end of the first harvest to the end of the whole harvest. In the second and third stages of fertilizer absorption, the characteristics of promoting tillage are similar to those in the open field, and the absorption of phosphorus and potassium fertilizer, especially potassium, increases. To sum up, hormone-free bird's nest water-soluble fertilizer can be used, and foreign double technologies can decompose nutritional macromolecules into small molecules, which are more easily absorbed by crops. Bird's nest water-soluble fertilizer is easy to absorb, and its absorption and utilization rate can reach 80%.
