The fruit has been stabilized, the citrus has entered a rapid expansion period, the fruit is the same every day, go to the orchard every day, look at the fruit of this tree, the heart is beautiful, but take a closer look, see some coarse peel fruit, inevitably lack of beauty, more worried about the end of the year if the peel is not smooth and delicate, there is no good price how to do?
The peel of the orange is somewhat coarse
Go home and lie on the bed, brush the mobile phone, find vibrato, WeChat circle of friends / video number, there are always people who say that spraying calcium in addition to puffing, but also peeling, want to try, but a little hesitant? Can calcium fertilizer really pull the skin? Therefore, this article will unveil for everyone, whether calcium fertilizer can peel, fine skin, improve coarse peel fruit!
Answer: Calcium does improve the coarse peel fruit. From the following two aspects for everyone to analyze
From the anatomical morphology of the peel
The dissection of the peel was observed, and the degree of disorder and intercellular space of the peel cells in the coarse peel of the coarse peel fruit were significantly greater than that of the smooth fruit in the same part of the same period, and calcium could be improved.
As the fruit continues to develop, the cell arrangement of the middle peel will become more and more loose, and air gaps will appear. Generally from the flowering began to approach the end of the oil cell (peel bulging oil cell) cell layer also began to appear loose arrangement, accompanied by fruit expansion, the middle peel in accordance with the order from the inside to the outside of the cell arrangement disorder and gap become larger phenomenon, but the coarse skin of the large fruit is more chaotic, the gap is larger, so the coarse skin late floating skin is serious. Morphologically, the cells of the coarse peel fruit are more slender, while the light peel fruit is mainly a smaller diameter round.
Is it more difficult to understand, you can combine the following peel anatomy diagram to see Oh ~
Calcium will form the mesmeral layer of the plant cell wall in the form of calcium pectinate, so that cells and cells can be connected to form tissues, and the organs or individuals of the plant have a certain mechanical strength, improving the loose arrangement of the cell layer and the large gap, so it can improve the coarse peel fruit.
Analyze from the perspective of nutrition
Taking the pear as an example, the nutrient content of the fruit, leaves and soil is measured for analysis.
First measure the fruit, in July, the ratio of normal fruit calcium content to crude peel fruit calcium content is 4.755:1, that is, the coarse peel fruit calcium is very low, significantly lower than the normal fruit calcium content in the same month. When the fruit continues to expand, in September, the ratio of normal fruit calcium content to crude peel fruit calcium content is 3.870:1, and the difference between crude peel fruit calcium content and normal fruit is still significant. The calcium content in both July and September coarse-skinned fruits was significantly lower than that of normal fruits, and the production of coarse-skinned fruits was associated with the extreme lack of calcium content in coarse-skinned fruits. Then the whole nitrogen in the coarse peel fruit is higher than that of the normal fruit.
Measuring the leaves next to the fruit, the leaves of the coarse peel fruit nitrogen, phosphorus and potassium are not significantly different from the normal fruit, but the calcium is also lower than that of the normal fruit.
Finally, the soil measurements showed that the available potassium content in each layer of the coarse-skinned orchard was significantly higher than that of the normal orchard, and the exchange calcium content in the coarse-skinned orchard was not significantly different from that of the normal orchard, that is, there was no lack of exchangeable calcium in the soil. It may be that the competitive absorption of potassium causes inhibition of calcium absorption in the tree and thus produces coarse peel fruit. However, our citrus crop area, especially the soil sample analysis of Guilin, found that the soil in Guilin is indeed very calcium-deficient.
This coarse skin is somewhat deformed, in addition to calcium, it is necessary to supplement boron to improve
So from the above analysis, we draw two conclusions like this:
1. The calcium content of the fruit part of the coarse peel fruit is significantly lower than that of the normal fruit
2. The lack of calcium in the fruit site may be related to too much potassium use, and it may also be a lack of calcium in the soil.
So it's feasible to improve the coarse peel fruit by supplementing with calcium, not nonsense is true, and in either case, leaf spray calcium fertilizer is effective.
Whether from the anatomical morphology of the peel or from the perspective of nutrient analysis, calcium can indeed improve the coarse peel fruit.
From the above data, we also know that whether it is because of nitrogen fertilizer, potassium fertilizer supplementation, or because the fruit is missing calcium, leaf spray calcium fertilizer, is useful for the improvement of coarse peel fruit. We also have practical examples to illustrate the problem, as shown in the following figure:
Fluid calcium was used last year and this year to improve the peel, which is fine and smooth

The peel is coarse, but it can also be improved! The fruit farmer spent 60 pieces of 2500 pounds of water, the effect is obvious, and the experiment is shared

Good results Fluid Calcium Amino-Sugar Alcohol Calcium ¥120 Purchase
Of course, the lack of calcium orchards or to take advantage of the current high potassium fertilizer time, supplement the trace elements, in addition to calcium, it is recommended that magnesium and boron also supplemented together, according to 119 orchards, for 3 consecutive years of investigation, basically all orchards in Guilin, there is a widespread lack of calcium, magnesium and boron. Calcium supplementation is not only to improve the coarse peel fruit, after all, the calcium in the plant is only 20% in the fruit, and the branches and roots need 80% of the calcium (calcium also helps the production of capillaries), which is a large demand. We suggest that at this stage, we can root leach polypeptide double enzyme in trace elements + batian fruit high potassium fertilizer, expanding fruit calcium supplementation to restore tree potential.
Among the many calcium fertilizers, we recommend that you use fluid calcium amino-sugar alcohol calcium at this stage, because the double chelating technology, in addition to the good effect, can also supplement amino acids, which helps the old ripening of the late summer shoots now, and is more conducive to the expansion of the fruit, that is, the puffed fruit and the fine skin.
Of course, if the orchard is too deficient in calcium, afraid of cracked fruits, etc., in order to be able to supplement a large amount of calcium, you can also use calcium, magnesium and boron essence, and the three are better supplemented together.
Then, after the fruit is completely stabilized, you can use the macroalgae pure calcium containing nitrogen, phosphorus and potassium and seaweed (5 liters is only 150 yuan).
Calcium + seaweed + nitrogen, phosphorus and potassium 5 liters 150 yuan ¥150 purchase
June is the period of rapid expansion of the fruit, the cell space begins to gradually increase, the cell arrangement is disordered, and the expansion of the fruit at this time is mainly the increase and thickening of the volume of the middle peel cells. Therefore, fluid calcium is now sprayed, and the roots are sprayed with chelated calcium, which accelerates the expansion of the fruit and weakens the production of the coarse peel fruit.
At present, this stage of coarse peel fruit more, but some orchard peel slightly coarser is a normal phenomenon, the later stage will slowly become thinner, until the thinnest coloring period, no special treatment, but some too thick or early to make plans, really rest assured, the same spray does not matter, anyway now the fruit expansion period is also the absorption peak of calcium fertilizer, you can spray fluid calcium / calcium magnesium boron essence / macroalgae pure calcium.
Wo citrus, at present, this needs to worry, seize the time to spray fluid calcium
Wo citrus currently peel so there is no need to worry
