The first element that can expand fruit is combined, that is, hydrogen oxygen h, O

We all know that these two often synthesize water. Water is an indispensable part of expansion. If there is water shortage when the fruit is expanded, then the expansion of the fruit will be impossible to talk about. By enriching the fruit with water, the fruit will become delicious and juicy. Many fruits contain a lot of water. This is also the source of the saying of fruit. At the same time, hydrogen and oxygen also make up sugar and protein And so on fruit many kinds of organic matter, therefore is must two important elements.



Second element: carbon C

As we all know, organic matter is basically composed of carbon, and sugar, protein, fiber and other substances are all structured with carbon. Therefore, carbon supplement is of great significance to the expansion of fruit, and has a better effect on improving the flavor and sweetness of fruit. 1、 To ensure the quality of leaves and smooth photosynthesis. 2、 At the same time, humic acid, amino acid polypeptide, sugar alcohol, seaweed extract, etc. are added to increase the absorption of small molecule carbon.

The third element: nitrogen n




In many cases, expansion and sweetness increase are two different concepts. Generally, the sweetness of the expanded fruit is relatively low, but the sweetness begins to appear in the later stage of maturity. Then the expanded fruit needs nitrogen supplement. The structural significance of nitrogen is to form amino acids and protein construction. If the nitrogen is insufficient, the fruit cells begin to appear incomplete when the fruit is expanded Cell membrane and nitrogen are also the elements of plant growth hormone synthesis. But when nitrogen is excessive, the fruit will grow in vain, which will lead to the decrease of fruit expansion. The key to fruit expansion is to master the appropriate amount of nitrogen.

The fourth element: Zinc



The use of zinc can increase the content of local indoleacetic acid in plants. At the same time, the transfer ability of zinc is not strong. If it is only used on the fruit, it can enhance the fruit as a metabolic active part to compete for nutrition and play a better role in expanding the fruit, but at this time, it must have enough organics as support, so as to play a better and more effective expansion Otherwise, the risk of cavitation or fruit resistance to external environment will decrease after the fruit enlargement. However, when the total zinc spray occurs, the content of indole acetic acid will increase to a certain extent, and the fruit swelling will be significantly different. At the same time, the use of zinc can make up for the disadvantage of the seed to a certain extent. After using zinc, the core grape can improve the ability of grabbing each fruit as a whole, which can obviously prevent the formation of large and small fruits.

The fifth element: potassium K

Potassium basically regulates the overall solubility of crops in plants, and can regulate the relationship between metabolism source and sink. Originally, it has a conflicting role with zinc. However, potassium is the balance between regulation source and sink of photosynthesis, which is conducive to the accumulation of photosynthesis materials to fruits, but it should be based on the next element.

The sixth element: Boron B



Boron is a very wonderful element in many times. If there is a lack of boron, the sugar produced by photosynthesis on the leaves will not be transported from the leaves to the fruits or roots, resulting in the lack of fruit content, so it is also the basis of organic matter that can play a better role.

Seventh Element: calcium CA

Calcium, as the second messenger, participates in the regulation of cell division. At the same time, the role of calcium as a basic element cannot be ignored. Calcium can stabilize the cell wall, improve the pectin adhesion between fruit cells, and prevent the cell wall from disintegrating and the carbon shelf from scattering when the fruit expands. It also plays an important role in preventing cell separation. Calcium plays an important role in growth As for potential, to some extent, it can control the advantage of the top, and it is also very good to prevent excessive growth.

Eighth element: magnesium mg



Most of the time, people are unfamiliar with magnesium. But the first function of magnesium is to form chlorophyll, but it must be completed by combining nitrogen, carbon and water. The increase of chlorophyll is only to provide organic matters more effectively. However, another function of magnesium is on seeds. Many crops can see a phenomenon that magnesium deficiency will be more serious after seed formation. In some seedless fruits, the degree of magnesium deficiency is lighter than that of seeded fruits Many, such as seedless watermelon.

As we all know, the sweetness of fruit is achieved by potassium, but the seedless watermelon has no seed, so the transfer of magnesium to seed is not obvious, so magnesium deficiency is not serious. However, after seed formation, when magnesium deficiency occurs, the leaves of seeded watermelon immediately show magnesium deficiency. If potassium deficiency occurs at this time, the sweetness of fruit will be obvious on seeded watermelon Lower. There are also grapes. Seeded grapes will suffer from magnesium deficiency after seed formation. In serious cases, their leaves will turn yellow, but their fruits are still very sweet, because they do not lack potassium. When magnesium is enough, magnesium can be transferred to multiple parts, but when magnesium is insufficient, magnesium will be limited in the supply of seed formation, because seed is the purpose of plant growth, not fruit Blade.

Why are the ninth and tenth elements mentioned together? The two elements are sulfur and phosphorus s and P



Phosphorus is the main element of energy material, mainly forming ATP. The movement speed of phosphorus in plant body should be more active among all elements. After ATP is formed from leaves, it will supply energy material for root system to absorb nutrition and synthesize amino acids. At this time, it will be very important. Sulfur is to improve the speed of photosynthesis, synthesize protein and make protein have The activity of enzyme determines the metabolic rate of the whole organism. One is to provide energy for the synthesis of sugar and amino acid, the other is to improve the activity of protein and enzyme, and to cooperate with each other for better expansion. If there is no phosphorus movement, then the plant will lose all the power, but when there is excessive phosphorus, it will lead to the premature phenomenon of the fruit without the completion of the expansion, and the fruit fiber will increase seriously.

Phosphorus is not a quality element, but it is a necessary element for energy transfer in many cases. Appropriate phosphorus is very important. Excessive phosphorus will fix trace elements such as calcium. After the enzyme activity of sulfur is increased, the speed of synthesis of organic compounds is increased. At this time, it is conducive to accumulation. It will be more obvious to strengthen each other through potassium and boron. However, after the application of sulfur on the base fertilizer, there is no need for additional supplement in the growth season, because the compound fertilizer and water-soluble fertilizer you use generally contain sulfur.

Other elements also play a great role in photosynthesis, such as iron, but relatively weak for swelling, mainly in the aspect of leaf green preservation and prevention of early yellow senescence, so they are not included. Many elements are indispensable, but they are interrelated in different aspects. Elements that are not mentioned do not mean that they have no effect, but they are not as direct as the above 10 elements in expanding.

However, the expansion of some crops, in addition to the above 10 elements, is not enough. For example, peanut, soybean, cucumber, tomato and other crops, if molybdenum fertilizer is used, the expansion effect will be very obvious. However, molybdenum fertilizer is expensive and few farmers are willing to invest heavily. Therefore, it has not been widely used.
