The growth of peach trees is just like that of humans—in every stage, it’s essential to provide adequate nutrients to meet their growth needs. Today, many peach trees have entered the fruit-development stage. If we miss the optimal fertilization period for peach trees, when the fruits begin to color and sweeten, we’ll likely encounter problems such as fruit cracking, small fruit size, and poor fruit quality. So, what trace elements must we ensure are adequately supplied during the fruit-expansion phase? Let’s find out below! Fertilizer supplier Let’s take a quick look!
1. Supplement calcium and magnesium
During fruit coloring and sweetening, the body’s annual calcium absorption and digestion account for as much as 60% of the total calcium intake. Magnesium is a key element that promotes chlorophyll production, leaf photosynthesis, and the metabolic processes responsible for fruit coloring and sweetness. A magnesium deficiency can severely impair the accumulation of nutrients and the successful development and growth of fruit coloring and sweetening.
2. Fill nitrogen
Nitrogen fertilizer is essential for peach tree growth; however, excessive nitrogen application can lead to an overabundance of shoots and branches, resulting in a severe conflict between shoot/branch development and fruit coloring and sweetness, thereby reducing both fruit coloration and sweetness. Moreover, adequate nitrogen supply can enhance the drought resistance of fruit coloration and sweetness, and help minimize the occurrence of abnormal fruit coloration and sweetness, as well as sunken skin and reddened skin on fruits.
3. Supplement potassium
Potassium is a key element for enhancing peach tree flowering and fruit-setting rates, promoting color development, increasing sweetness, improving fruit set, and accelerating fruit coloring. While applying potassium fertilizer as a topdressing, also spray the leaves with an aqueous solution of potassium dihydrogen phosphate, taking into account the specific conditions of the peach trees. If the soil in the plantation is acidic or alkaline, apply an appropriate amount of lime powder to the orchard to neutralize the pH, thereby improving the root system's ability to efficiently absorb calcium from the soil. In addition, it is essential to supplement any deficiencies in nutrients such as iron, zinc, and boron. This will promote better fruit set and growth, ensure uniform fruit coloration, and increase sugar content and flavor intensity.
That’s all above. Fertilizer supplier The editor provides a brief introduction to the importance of supplementing trace elements during the fruit-swelling stage of peach trees, hoping you can learn more about this topic.
