Nitrogen Fertilizer or Potassium Fertilizer: Which One Makes Fruit Swell Faster? Choose Fertilizer This Way During the Fruit-Swelling Period

Nitrogen fertilizer and potassium fertilizer are sources of nutrient supplementation during plant growth; rational application can make plants grow more luxuriantly. Nitrogen fertilizer or potassium fertilizer: which one makes fruit swell faster?

1. Nitrogen fertilizer or potassium fertilizer: which one makes fruit swell faster

Currently the two have not been specifically compared; the plant growth process requires relatively many trace elements, and plants do not grow relying on a single element.

Comparatively speaking, potassium fertilizer makes fruit swell faster than nitrogen fertilizer. When young fruit is swelling, an appropriate amount of nitrogen fertilizer needs to be supplemented to promote growth and provide nutrition, while potassium fertilizer is a substance urgently needed for supplementation after fruit set; the two fertilizers play important roles at different stages of plant growth and complement each other.

2. The role of the nutrient elements required during the fruit-swelling period

1. Fruit from the first and second fruit-swelling stages generally has relatively low sweetness, and sweetness only begins to appear after color change. When young fruit begins to swell, nitrogen element needs to be supplemented; nitrogen is the basic element of amino acids and proteins. If nitrogen is insufficient, during swelling the protein synthesis of fruit cells is blocked, and cell division is also restricted. Nitrogen is also a basic constituent element of plant growth hormones.

Excess nitrogen will cause excessive fruit growth and lead to decreased sweetness; before the fruit changes color, especially during the first swelling of young fruit, applying an appropriate amount of nitrogen is the key.

2. Potassium can regulate the metabolic source and photosynthetic products in the plant body; it is an important element that promotes fruit swelling and color change, is conducive to the accumulation of photosynthetic products in the fruit, and can increase the sugar content in the fruit.

3. Calcium can stabilize the cell wall structure, and at the same time participates in the formation of intercellular cementing substances, improves the adhesion between fruit cells, and reduces the probability of fruit cracking. It improves the glossiness of the fruit surface and reduces the occurrence of diseases such as bitter pit, playing a great role in increasing the yield and income of the fruit.

4. Boron can not only promote the metabolism of calcium, but also promote the transfer of organic matter from the xylem to the phloem. If boron is deficient, then the photosynthetic products of the leaves will be unable to be transported to the fruit or root system, resulting in a lack of dry matter in the fruit.

5. Magnesium is the main component of chlorophyll; sufficient magnesium can promote photosynthesis and increase the accumulation rate of organic matter, thereby promoting fruit swelling.

When growing fruit trees, all aspects need to be taken into comprehensive account; none of the various trace elements can be lacking, and at the same time they must not be given too much, for extremes meet.
