How to grow strawberries?
Strawberry planting management method:

1. The fertilizer absorption of strawberry in open cultivation can be divided into four stages:

1. During the four-month growth period from planting to natural dormancy, the absorption of nutrients is relatively low due to plant dormancy. According to the analysis of plant dry matter, the absorption ratio of nitrogen, phosphorus and potassium in this period is 1: 0.34: 0.3, and the most nitrogen is absorbed.

2. After the natural dormancy was released, the plants grew vigorously, and the nutrient absorption increased compared with the previous stage. The absorption ratio of nitrogen, phosphorus and potassium in this stage was 1: 0.26: 0.65.

3. From the budding stage to the flowering and fruit-setting stage, with the increase of air temperature and soil temperature, the plant entered the vigorous growth stage, during which the absorption and consumption of nutrients reached the peak, and the absorption rate of nitrogen, phosphorus and potassium was 1: 0.28: 0.93, and the absorption rate of potassium further increased.

4. From flowering to fruit setting, the proportion of nitrogen absorbed by plants decreased, the amount of phosphorus and potassium absorbed increased, and nitrogen, phosphorus and potassium were absorbed. The ratio is 1: 0.37: 1.72, and the absorption rate of potassium reaches the peak.

2. Fertilizer absorption of strawberry cultivated in greenhouse can be divided into three stages:

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%.
