The warmer spring weather, increased air humidity, and artificial factors such as fertilization can easily cause strawberry growth and affect yield.
Reasons for strong growth: Watering too much: Strawberry absorbs too much water, and its vegetative growth is greatly enhanced. It starts to grow, consumes photosynthetic nutrients and mineral nutrients, and the nutrients allocated to fruits, roots, and flower buds will be relatively reduced. Flower buds are difficult to form, root growth is inhibited, and flowering branches will be extended in the later stages.
Too much nitrogen fertilizer: If too much nitrogen fertilizer is applied, the increase in nitrogen will cause excessive growth, the color will be green, the plant will be soft, and it will be vulnerable to human damage, which will further cause various diseases. The stem is thin, the petiole becomes thin, and it is easy to lodging; too many leaves will also make the ventilation and light transmission worse, and it is easy to make the middle and lower leaves prematurely senescent.
The temperature is higher: The suitable temperature during the day is 23 ~ 25 ℃, and it is 8 ~ 10 ℃ at night, which is conducive to flowering and pollination and fertilization. The temperature began to rise in spring, plant growth speeded up, and combined with ample fertilizer and water, just like strawberry seedlings grew quickly in high temperatures in summer, causing long legs.
The most fundamental reason for the strong solution is excessive fertilizer and water. A large amount of basal fertilizer has been applied before planting. If the water is not controlled at this time, a large amount of nitrogen is absorbed by the plant, and the result is bound to be long. So the easiest and most direct way is to control the moisture and reduce the available nitrogen fertilizer.
Increase the ventilation to reduce the temperature in the shed. At this stage, it is necessary to increase the air outlet on sunny days, increase the ventilation volume, and effectively reduce the temperature in the shed, especially the night temperature. Control the temperature within a reasonable range.
You can add a low concentration of potassium dihydrogen phosphate to increase the thickness of the leaves while carrying out chemical control. Do not spray potassium dihydrogen phosphate during the flowering season. You can apply an appropriate amount of phosphorus and potassium fertilizers to control the growth of 300-500 times.
If the amount of side buds is large, they should be dredged out in time to avoid excessive side buds from wasting nutrients. Generally, 1 to 2 side buds can be left per plant. The ripe strawberries on the plant should be removed in time to avoid affecting the subsequent strawberry growth.
Too dense plants should promptly chop off old leaves, diseased leaves and overly dense overlapping leaves to create an airy and transparent environment for strawberry plants to facilitate their growth.
