What nutrients need to be supplemented during the strawberry fruit-swelling stage?
Strawberries go through multiple growth stages throughout their entire growth process. Among them, the fruit-swelling stage is one of the most important stages for strawberries. The growth during the strawberry fruit-swelling stage directly affects the strawberry's yield and fruit quality. And if you want the strawberry fruit to expand normally, then nutrient supplementation is very crucial. Therefore, during the strawberry fruit-swelling stage, there are many nutrients that need to be supplemented in a timely manner. So which ones specifically? Let's take a look below!
1. Hydrogen and oxygen
Hydrogen and oxygen 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 most needed for strawberry fruit swelling. When strawberries are swelling, if they lack water, they definitely cannot expand normally. This leads to deformed, small, and other poor-quality fruits in strawberries. Moreover, hydrogen and oxygen are also important elements that make up organic matter such as sugars and proteins, and are very crucial to strawberry growth. Therefore, during the strawberry fruit-swelling stage, everyone must pay attention to timely supplementation of hydrogen and oxygen.
2. Nitrogen
Besides 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 fruit sugar content. When 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, nitrogen should be properly controlled to effectively increase sweetness. Nitrogen is also a main element for synthesizing plant hormones, but it must not be used excessively, otherwise it can easily cause strawberries to grow leggy, thereby affecting fruit swelling. Therefore, everyone must control the amount of nitrogen used well.
3. Zinc
The zinc element is very beneficial to strawberry fruit swelling. Reasonable use can increase the local auxin content of strawberry plants. The mobility of zinc is not strong. If applied to the fruit, it can also enhance the fruit's metabolic capacity, compete for nutrients, and promote better fruit swelling. However, it also needs the support of a large amount of organic matter to ensure its fruit-swelling effect. Otherwise, after the fruit swells, hollow fruits and similar phenomena are likely to appear, or the fruit's resistance will also decline 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 strawberry growth. It is also a key component of chlorophyll. During strawberry photosynthesis and respiration, 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 will have a great impact on strawberry quality and yield, reducing fruit flavor and causing whitening and other phenomena, 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's all for today's introduction. This article is for reference only, and we hope it can help everyone!
