Effects of Nutrient Elements in Fruit Setting Stage
1. The secondary fruit setting is generally lower in sweetness, and the sweetness begins to appear after the color changes. Nitrogen needs to be supplemented when the young fruit begins to set. Nitrogen is the basic element of amino acids and proteins.
Insufficient nitrogen, during fruit setting, the protein synthesis of fruit cells is blocked, and cell division is also limited. Nitrogen is also the basic building block of plant growth hormones.
Excessive nitrogen will lead to excessive fruit growth and reduce the sweetness. Before the fruit turns color, especially when the young fruit setting for the first time, it is the key to apply nitrogen in moderation.
2. Potassium can regulate metabolic sources and photosynthetic products in plants. It is an important element to promote fruit setting and color change when the young fruit setting. It is conducive to the accumulation of photosynthetic products in fruits and can increase the content of sugars in fruits.
3. Calcium can stabilize the cell wall structure, and during the fruit setting participate in the formation of intercellular cementitious substances, improve the adhesion between fruit cells, and reduce the probability of fruit cracking. Improving fruit surface gloss and reducing the occurrence of bitter pox and other diseases have a great effect on increasing fruit production and income.
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, the photosynthetic products of the leaves will not be able to be transported to the fruit or the root system, resulting in a lack of dry matter in the fruit.
5. Magnesium is the main component of chlorophyll. A sufficient amount of magnesium can promote photosynthesis and increase the accumulation rate of organic matter, thereby promoting the fruit setting.
