Which is faster to expand fruit, nitrogen fertilizer or potash fertilizer?

Nitrogen fertilizer and potassium fertilizer are the sources of nutrition supplement in the process of plant growth, and reasonable application can make plants grow more luxuriantly. Which is faster to expand fruit, nitrogen fertilizer or potassium fertilizer?

Which is faster, nitrogen fertilizer or potash fertilizer?

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

Comparatively speaking, potash fertilizer expands fruit faster than nitrogen fertilizer. When young fruit is enlarged, appropriate amount of nitrogen fertilizer is needed to promote growth and provide nutrition, while potassium fertilizer is an urgent supplement after fruit setting. The two fertilizers play an important role in different stages of plant growth and complement each other.

Second, the role of nutrient elements during fruit expansion.

The main results are as follows: 1. The sweetness of the fruit of the first and second expansion is generally lower, and the sweetness begins to appear after changing color. Nitrogen is needed when the young fruit begins to expand, which is the basic element of amino acids and proteins. Due to nitrogen deficiency, the protein synthesis of fruit cells was blocked and cell division was restricted during expansion. Nitrogen is also the basic constituent element of plant growth hormone.

Excessive nitrogen will lead to excessive growth of fruit and decrease in sweetness. before the fruit changes color, especially when the young fruit expands for the first time, appropriate amount of nitrogen application is the key.

2. Potassium can regulate metabolic sources and photosynthates in plants, which is an important element to promote fruit expansion and color conversion, is conducive to the accumulation of photosynthates to fruit, and can increase the content of sugar in fruit.

3. Calcium can stabilize the structure of cell wall, participate in the formation of intercellular cementing substances, improve the adhesion between fruit cells and reduce the probability of fruit cracking. Improving the glossiness of fruit surface and reducing the occurrence of diseases such as bitter pox disease play an important role in increasing fruit yield and income.

4. Boron can not only promote calcium metabolism, but also promote the transfer of organic matter from xylem to phloem. If boron is deficient, the photosynthates from leaves will not be able to transport to the fruit or roots, 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, thus promoting the expansion of fruit.

In the planting of fruit trees need to be fully taken care of, all kinds of trace elements are indispensable, at the same time can not be given too much, things will be reversed at the extreme.
