Fertilizer for increasing sugar content of mandarin oranges and preparation method thereof

Abstract

The invention discloses a fertilizer for increasing the sugar content of mandarin oranges and a preparation method thereof, which relate to the field of fertilizers. The fertilizer comprises the following components in parts by mass: 100-200 parts of nitrogen fertilizer master batch, 20-40 parts of humic acid, 3-10 parts of nano diatomite, 10-20 parts of silicon dioxide, 0.1-2 parts of an inhibitor and 2-10 parts of a stabilizer. According to the fertilizer for increasing the sugar content of the mandarin oranges, the utilization rate of the fertilizer is increased, the soil structure is improved, and the sugar content of the mandarin oranges is increased; humic acid is a macromolecule with an aromatic ring and an alicyclic ring as basic structures, carboxyl, hydroxyl, carbonyl, quinonyl, methoxyl and other functional groups are connected to the ring, the utilization rate of the fertilizer can be obviously increased through the ion exchange and chelating effects of the humic acid, meanwhile, the ion exchange of the humic acid can help soil to be agglomerated into a particle structure, and therefore the porosity and air permeability are improved; the lignite is activated by nitric acid with certain oxidability, macromolecular lignite humic acid can be oxidized into micromolecular lignite humic acid, and the cation exchange capacity can be improved.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a fertilizer for increasing the sugar content of tangerines and a preparation method thereof. Background technique [0002] The sweetness of tangerine is determined by the amount of sugar in its cells, while the accumulation of sugar is closely related to nitrogen, phosphorus, potassium and other trace elements. From the flowering of the fruit tree to one month after the flowering, the cells of the young fruit are in a state of division, and the cells are full of cytoplasm with protein as the main component. After that, the cell division stops and begins to rapidly absorb water and expand, and the cell wall extends outward. At this time, the cytoplasm gradually adheres to the periphery of the cell membrane, and a large vacuole is formed in the center, and the bubble fluid is inside, which is the main place for the fruit to store starch, organic acids and other substances. ...

Problems solved by technology

[0003] However, if too much nitrogen fertilizer is applied, although it is beneficial to the formation of protein, it will increase the cytoplasm in the cell, resulting in the delay of the mononuclear marginal phase of the cytoplasm and the corresponding decrease in the volume of the vacuole, which directly hinders the storage of starch.

At the same time, applying too much nitrogen fertilizer will make the new shoots of fruit trees grow vigorously, consume a large amount of sugar produced by the leaves in growth, reduce the transportation to the fruit, and affect the sweetness of the fruit

[0004] Studies have shown that nitrogen in fertilizers cannot be directly absorbed by plants and needs to be converted into ammonium through hydrolysis and nitrification into nitrate; while urea is usually hydrolyzed in the soil under the action of urease to produce ammonia and carbon dioxide, resulting in ammonia nitrogen At the same time, after a large amount of urea is hydrolyzed, the ammonia dissolved in the water in the soil will increase the pH value of the soil, and a high pH value will lead to the precipitation of mineral elements and reduce the availability of nutrients.

[0005] The publication number is CN108129240A, and the name is a Chinese application for a fertilizer specially used to increase the sweetness of citrus. By adding selenium-rich organic fertilizer and microbial microbial agent to the urea-based compound fertilizer, the balance of various nutrients is maintained, and the increase in While increasing the yield of citrus and the weight of a single citrus, it can also increase the sweetness of citrus. Applying this fertilizer can adjust the effective components of the soil, but it is not easy for plants to absorb, and it is easy to cause the loss of fertility, and frequent fertilization, charged soil clay Ionic combination with fertilizers will cause soil compaction, lower soil air permeability, affect the operation of plant roots, and is not conducive to the accumulation of fruit sugar

And can improve soil structure in all aspects, the fertilizer that is specially used in increasing the sweetness of tangerine has not been reported
