How to Control the Prosperity of Strawberries in Early Spring

Recently, the temperature has risen rapidly, and the growth rate of strawberries has begun to accelerate. At this time, water and fertilizer management should adhere to the principle of "promoting the combination of control and focusing on control". If the fertilizer and water are not properly managed, one will cause the plants to become weak and prematurely aging, and the other will cause the strawberry plants to grow vigorously. Both of these situations will cause the total output of strawberries to decrease and affect the profit. Therefore, in the early spring season, our management should be classified according to the situation of seedlings.

What adverse effects will the prosperous spring bring to strawberries?

1. The emergence of prosperous plants, flowering and fruit setting will be greatly affected. Many friends have broken strawberry stubble after spring starts. Therefore, we must control them before prosperous growth. Once they grow, it is difficult to control them back.

2. The production of strawberry has dropped sharply. The vigorous plants have less fruit and small flowers.

3. Strawberry plants have young and tender leaves, slender stems, poor resistance to stress, and easily induce diseases such as gray mold and powdery mildew.

Therefore, the purpose of controlling prosperity is to adjust the balance of vegetative growth and reproductive growth of strawberries, so that strawberries have more flowers and more fruit.

What are the reasons for the prosperous growth of strawberries in spring?

1. The temperature rises. In spring, the temperature warms up and the absorption capacity of strawberry roots increases, resulting in faster growth of strawberry plants.

2. Sufficient fertilizer and water. This period is the strawberry fruiting period and cropping period, and the supply of water and fertilizer in the shed is relatively sufficient.

3. Especially for strawberries in the stubble period, when most of the strawberry fruits in the previous stubble are removed, the burden on the strawberry plant is suddenly reduced, and the nutrients will quickly flow back to the stems and leaves, which is manifested by elongated stems, lighter leaves, and new growth. The leaves are big and thin.

For plants that grow well and tend to grow, we must take "control" measures to prevent them from flourishing due to increased temperature and sufficient fertilizer and water.

One is to control the temperature. Due to the increase in the outside temperature, the temperature inside the shed is relatively high and the temperature difference between day and night is reduced. If sufficient water is added, it is easy to promote the growth of plants. Therefore, the temperature in the shed can be controlled by the following two steps in the near future:

1. Normally, the temperature can be adjusted by opening the air vent early and closing the air vent at night.

2. If the temperature rises rapidly at noon on a sunny day, a large vent should be opened to increase the ventilation in the shed. If the temperature in the shed reaches 28°C, the down vent can be opened. Can effectively reduce the temperature in the shed.

The temperature in the shed during the day should be controlled within 25°C. Especially at night, the temperature should not be high. Try to increase the temperature difference between day and night. Keep the temperature in the shed at about 5℃ at night. To promote the differentiation of the next flower buds.

The second is to control water and fertilizer. Do not arbitrarily increase the amount of water and fertilizer to expand the fruit, especially the moisture and nitrogen fertilizer should be properly controlled to ensure that the water and nutrients in the soil are enough to expand the fruit.
