What Fertilizers Are Needed For Strawberry Fruit Expansion?

What fertilizers are needed for strawberry fruit expansion?

1. Hydrogen and oxygen Hydrogen and oxygen are two essential elements for the growth of strawberries, especially during the fruit expansion period. Hydrogen and oxygen are the basic substances for the synthesis of water, and water is necessary for strawberries during the fruit expansion period. During the fruit expansion period of strawberries, if there is a lack of water, the strawberries will basically not be able to expand. Moreover, hydrogen and oxygen are also the main elements that constitute various organic substances such as sugar and protein. Therefore, when we fertilize during the fruit expansion period, we must pay attention to replenishing these two elements in time.
2. Nitrogen fertilizer During the fruit expansion period, nitrogen fertilizer should be appropriately supplemented to increase the sweetness of strawberry fruits. When the strawberry fruit swells, its sweetness is not high, and sweetness generally does not appear until the later stages of maturity. During the fruit expansion period, controlling nitrogen fertilizer can effectively increase the sweetness of the fruit. At the same time, nitrogen is also the main element for the synthesis of growth hormones in strawberry plants. Therefore, nitrogen fertilizer should not be too much. If it is too much, it will easily cause the strawberry plants to grow elongated, thus affecting the expansion of the fruit. Controlling the amount of nitrogen fertilizer is the key to ensuring the normal expansion of strawberries.
3. Zinc fertilizer Zinc fertilizer can increase the local auxin content of the plant. Moreover, the transfer ability of zinc is relatively weak. If it is only used on fruits, it can enhance the ability of fruits to snatch nutrients, thereby enhancing the fruit's ability to expand. However, at this time, sufficient organic matter is needed as support to ensure fruit expansion. Otherwise, hollowing may occur after fruit expansion, and the fruit's resistance to the external environment will also be reduced. Spraying zinc fertilizer on the entire plant can increase the overall auxin content. Make up for the weakness of seeds, thereby reducing the phenomenon of large and small fruits.

4. Magnesium fertilizer Magnesium is an important element that makes up chlorophyll, and it is also an indispensable trace element for the growth of strawberries. Magnesium can activate various enzymes and nucleic acids during photosynthesis and respiration of strawberries. Unlike zinc, magnesium can be transferred. If the plant is deficient in magnesium, the old leaves will gradually yellow and wither, turn brown and scorch, and there will be brown spots between the veins. Symptoms will get worse over time. Magnesium deficiency during the fruit expansion period will be very detrimental to the yield and quality of strawberries, and will also cause bleaching, so everyone must pay more attention.
In general, fruit growth is inseparable from fertilizers. Fertilizers contain various elements. Therefore, everyone should also pay attention to the supplement of the above fertilizer elements during the fruit expansion stage of strawberries.
