In the production of strawberry, when several batches of fruit are picked, the soil often has insufficient nutrient supply. The fertilization in the habitual soil can not meet the high-yield and high-quality needs of strawberries. The rate of fruit-fruit is often decreased, and the fruit and deformed fruit are increased. The reduction in shape and shape has seriously affected the yield and quality of strawberries. Practice has proved that the use of foliar multiple top dressing in the flowering period is an effective way to reduce the yield and quality of small fruit and deformed fruit.
Strawberry foliar topdressing has the advantages of low cost, high fertilizer utilization rate, fast fertilizer efficiency, high product quality and low return on investment. Strawberry leaf top dressing operation technology is:
1. Choosing the leaf-seeding fertilizer should be targeted. According to the crop and soil fertility status, the nutrient elements and the number of times of application should be supplemented. The local use of leaf fertilizer is accustomed to potassium dihydrogen phosphate plus urea, superphosphate and urea, and compound fertilizer. , boron fertilizer and Greenway 18, Tianyuan nutrient solution and other commercial liquid fertilizer.
2, control the concentration and dosage to prevent waste and fertilizer damage, must control the concentration and dosage, the relevant fertilizer use concentration should be controlled: urea 0.3% -0.5%, superphosphate 2% -4%, potassium dihydrogen phosphate 0.25-0.4%, boron fertilizer 0.05-0.1%, Greenway 18 days, Tianyuan nutrient solution and other 500-800 times liquid. Generally, the fertilizer is 30-40 kg.
3. Master the timing of leaf surface chasing. The main use of this county is: spraying the green gerient 18 nutrient solution before the flowering, spraying the boron fertilizer during the flowering period, spraying the potassium dihydrogen phosphate plus urea when the fruit is swollen, or Calcium phosphate plus urea, or liquid nutrient solution such as Tianyuan nutrient solution. At the same time, it is better to choose 2-3 in the afternoon on sunny days, and the cultivation in open field should be around 4 o'clock. Once every 10-15 days, even spray 2-3 times.
4. Grasp the spraying part. When spraying, be sure to spray the front and back sides evenly, and do not leak the spray, do not re-spray, the stems and leaves are not wet.
It is worth noting that it should be sprayed at noon or rainy and windy weather; in cold winter, the water used for fertilizer should be adjusted to the temperature close to the shed as much as possible; after the strawberry shed in the greenhouse, the door and window should be opened at appropriate time and in moderation. The shed film is ventilated to reduce the humidity in the shed.
