Which of nitrogen fertilizer or potash fertilizer will expand fruit faster? What are the functions of nutrient elements required during fruit expansion? It is understood that nitrogen fertilizer and potassium fertilizer are sources of nutritional supplements during plant growth, and reasonable application can make plants grow more lush. So which one of nitrogen fertilizer or potash fertilizer will expand fruit faster?

At present, there is no special comparison between the two. The plant growth process requires more trace elements and does not rely on a single element to grow.

In comparison, potash fertilizer is faster than nitrogen fertilizer. When the young fruit expands, it needs to be supplemented with an appropriate amount of nitrogen fertilizer to promote growth and provide nutrients. Potassium fertilizer is an urgent need to supplement after the fruit is set. The two fertilizers play an important role in different stages of plant growth and complement each other.

The role of nutrient elements required during fruit expansion

1. The fruit of the second expansion is generally low in sweetness, and the sweetness starts to appear after the color changes. When the young fruit begins to expand, it is necessary to supplement nitrogen, which is the basic element of amino acids and protein. Insufficient nitrogen, when swelling, the protein synthesis of fruit cells is blocked and cell division is also restricted. Nitrogen is also a basic element of plant growth hormone.

Excessive nitrogen will lead to excessive growth of the fruit and reduce the sweetness. Before the fruit turns color, especially when the young fruit expands for the first time, proper nitrogen application is the key.

2. Potassium in plants can regulate the source of metabolism and photosynthetic products. It is an important element to promote fruit expansion and color change. It is beneficial to the accumulation of photosynthetic products in the fruit and can increase the sugar content in the fruit.

3. Calcium can stabilize the structure of the cell wall and participate in the formation of cementation between cells, improve the adhesion between fruit cells and reduce the probability of fruit cracking. Increasing the surface glossiness of the fruit and reducing the occurrence of diseases such as bitter pock have a great effect on increasing the yield and income of the fruit.

4. Boron not only promotes calcium metabolism, but also promotes the transfer of organic matter from the xylem to the phloem. If there is a lack of boron, the photosynthetic products of the leaves will not 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, increase the rate of organic matter accumulation, and promote fruit expansion.
