The latest matters needing attention in strawberry fertilization

Strawberry is a very popular fruit, not only because of its delicate appearance, but also because of its sweet and sour taste, men, women and children like to eat strawberries, so the price of strawberries in the market is still relatively high, the economic benefit is better. If strawberries want to grow well, fertilization is more important, so what should we pay attention to in strawberry fertilization? Let's take a look.

First, whether to apply fertilizer at flowering stage

The main results are as follows: 1. Strawberries may be topdressing at flowering stage, and phosphorus and potassium fertilizers are generally applied, because in the flowering and fruiting period, once there is a lack of water, phosphorus and potassium fertilizers, the cold resistance of strawberries will be reduced, with few flowers and weak buds, affecting flowering and fruiting. Not only the fruit setting rate is low, but also lead to poor coloring, sugar content in summer, extremely easy to rot and deteriorate, not resistant to storage and preservation. Therefore, attention must be paid to the application of phosphorus and potassium fertilizer during the strawberry period to prevent strawberries from affecting yield and quality due to lack of phosphorus and potassium.

2. In the flowering and fruiting period, phosphate and potassium fertilizer must be applied every 15-20 days, each time 40-50 kg of potassium dihydrogen phosphate per mu, or 70-80 kg of rotten bone powder, diluted 80-100 times with water, it can be evenly drenched in the root soil of the plant. In addition, a low concentration of potassium dihydrogen phosphate solution can be sprayed evenly on all leaves, buds, flowers and fruits every 7-10 days.

II. Matters needing attention in fertilization

1. The drip irrigation pipe is laid in the air to prevent the sediment from blocking the drip air or strawberry roots growing into the drip hole, causing blockage.

2. The spacing of drip holes in drip irrigation pipe should be reasonable to ensure that the wet cross section formed by drip holes in drip irrigation can be overlapped.

3, if it is the north greenhouse strawberry topdressing water had better be above 20 degrees, so as not to reduce the low temperature, which is disadvantageous to the root growth.

4. After blooming and fruiting, strawberries should be fertilized every time. They should be watered for 20 minutes before fertilization, and then watered for 10 minutes after fertilization.

5, strawberry throughout the growing period of a single high potassium fertilizer, such as potassium sulfate had better not exceed 3 times.

6. Watering and topdressing should be determined according to the weather, soil fertility and seedling growth.

7. Calcium, boron, iron, magnesium and other trace elements should be supplemented when topdressing.
