What nutrients need to be supplemented during the strawberry fruit-swelling stage?
Strawberries go through multiple growth stages over the course of their entire growth process. Among them, the fruit-swelling stage is one of the most important stages for strawberries, and the growth during the strawberry fruit-swelling stage directly affects the yield and fruit quality of strawberries. If you want the strawberry fruits to swell normally, then nutrient supplementation is crucial. Therefore, during the strawberry fruit-swelling stage, many nutrients need to be supplemented in a timely manner. So which ones specifically? Let's take a look below!
1. Hydrogen and oxygen
Hydrogen, oxygen and other elements are two indispensable nutrients during the strawberry fruit-swelling stage. This is because hydrogen and oxygen are the main elements for synthesizing water, and water is the substance strawberries need most for swelling. When strawberries are swelling, if they lack water, then they definitely cannot swell normally. This leads to various undesirable fruits such as deformed and shrunken strawberries, and hydrogen and oxygen are also important elements that make up organic matter such as sugars and proteins, which is very critical for the growth of strawberries. Therefore, during the strawberry fruit-swelling stage, everyone must be sure to supplement hydrogen and oxygen in a timely manner.
2. Nitrogen
In addition to hydrogen and oxygen, nitrogen is also a very important nutrient during the strawberry fruit-swelling stage. When strawberry fruits are swelling, appropriately supplementing some nitrogen can effectively increase the fruit's sugar content. When the fruits are swelling, the fruit sugar content is generally not very high; usually the sweetness only increases in the later stage of fruit ripening. Therefore, at this time, appropriately controlling nitrogen can effectively increase the sweetness. Nitrogen is also the main element for synthesizing plant hormones, but it must not be used in excess, otherwise it can easily cause strawberries to grow leggy, thereby affecting fruit swelling, so everyone must control the amount of nitrogen used well.
3. Zinc
Zinc is very beneficial for strawberry fruit swelling. Reasonable use can increase the local auxin content of strawberry plants. Zinc has weak mobility, and if applied to the fruits, it can also enhance the metabolic capacity of the fruits, compete for nutrients, and promote better fruit swelling. However, it also needs to be supported by a large amount of organic matter, so as to ensure its fruit-swelling effect. Otherwise, after the fruits swell, phenomena such as hollow fruits may easily appear, or the resistance of the fruits will decrease as a result. However, reasonably spraying zinc fertilizer can, to a certain extent, compensate for seed weakness and avoid the phenomenon of uneven fruit sizes.
4. Magnesium
Magnesium is an indispensable trace element for strawberries during growth. It is also a key component of chlorophyll, and during the photosynthesis and respiration of strawberries, it can activate some enzymes and nucleic acids. If the plant lacks magnesium, then phenomena such as yellowing leaf margins and brown, withered leaves will appear. In the middle and later stages, the spots gradually necrose. Most importantly, magnesium deficiency has a great impact on the quality and yield of strawberries, reducing fruit flavor and causing phenomena such as whitening, so everyone must pay close attention.
The above is a brief introduction to the nutrients that need to be supplemented during the strawberry fruit-swelling stage. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
