Background
The latitude of the grape producing area most suitable for wine in the world is 30-50 degrees of north and south latitude. In China, the soil of the high-quality wine grape producing area in the latitude area is mostly alkaline. The content of trace elements in the alkaline soil is low, which is not beneficial to the growth of the wine grapes. In order to improve the yield and the quality of wine grapes, grapes need to be fertilized, but blind fertilization in wine grape production areas is serious. And usually only the application of macroelement fertilizers is paid attention to, but the application of trace element fertilizers is ignored, so that the trace elements of wine grape trees are deficient. Particularly, under the condition of low temperature in spring, the wine grapes are easy to cause physiological iron deficiency yellowing. Iron deficiency has become a serious nutritional problem threatening the production of wine grapes. The function of the trace elements in the growth and development of the fruits is as important as the major elements such as nitrogen, phosphorus, potassium and the like, and the trace elements cannot be replaced by the major elements. The iron, magnesium and zinc elements are mainly involved in the formation of chlorophyll, which is the most important substance for normal photosynthesis of fruit trees. The proper amount of supplementary Fe, Mg and Zn fertilizer can raise the yield, Vc content, protein and chlorophyll content and leaf photosynthesis of crop obviously.
Researchers and fruit tree growers at home and abroad adopt various methods for correcting the iron deficiency chlorosis of fruit trees, including crown spraying, soil application, strong high-pressure injection and the like, the selected products are mostly ferrous sulfate and chelated iron, although the fertilizer is suitable for soils with different pH types, the fertilizer efficiency is high, but the price is higher, and the generated economic benefit is lower; the more applied iron ethylene diamine tetraacetate has poor stability, cannot be used on calcareous soil, is often used as a foliar spray fertilizer, but can become a persistent organic pollutant to accumulate in the environment under natural conditions, and the improvement effect is not ideal.

The nano silicon material is used as a carrier, various nutrient components are adsorbed on the nano silicon material, and the solubility of the nano silicon material in the amino acid stock solution is higher, so that soluble nutrient substances with high concentration in a conditioner can be ensured, and the storage and transportation cost can be effectively reduced. After being mixed into water, the fertilizer can be uniformly mixed with the water quickly, and substances such as sediment and the like can not be generated, so that the fertilizer is suitable for fertilization modes such as drip irrigation, foliage spraying and the like. And the amino acid stock solution as an organic substance can be absorbed by plants or microorganisms in soil, so that the burden on the soil is avoided.
The following will further illustrate the embodiments of the present invention with reference to examples;
the implementation case is as follows:
and performing a special conditioner field test for yellowing of wine grapes in Ningxia Yinchuan city Lilan wine in 2019 from 5 months to 7 months. The tested grapes are 6-year-old Cabernet Sauvignon (Cabernet Sauvignon), the grapes are planted in the north-south direction, the row length of a test cell is 50 m, the row spacing is 3 m, the plant spacing is 0.6 m, and the shaping mode adopts an upright dragon trunk shape.
In the field test, a random block design is adopted, four treatments of no micro-fertilizer application, chelated iron spraying, ferrous sulfate hole application and conditioner spraying and dripping are combined, and the effect of the conditioner special for wine grape yellowing on the improvement of the wine grape yellowing is determined through the analysis of wine grape chlorophyll, light and light characteristics, yellowing incidence, wine grape root, stem and leaf and iron content indexes in soil.
Treatment 1: no need of applying trace fertilizer
And (3) treatment 2: spraying of chelated iron
And (3) treatment: hole application of ferrous sulfate
And (4) treatment: special conditioner for wine grape yellowing by spraying and dripping

Wherein the spraying concentration of the chelated iron is 0.3 percent, and the dosage per mu is 300 g; and the spraying concentration of the special conditioner is 0.3 percent, the dosage per mu is 300 g, and the spraying concentration is matched with the drip irrigation for 4 kg per mu. The application of the fertilizer according to the application amount can ensure that the growth of the wine grapes respectively achieves the best effect of applying the chelated iron for spraying, the ferrous sulfate and the special conditioner.
TABLE 1 Effect of four treatment regimes on wine grape yellowing
| Treatment of | Chlorophyll content （mg/g） | Photosynthetic Rate (umol ™ Harbin m2/s) | Stomatal conductance (mmol- m2/s) | Intercellular CO2Concentration of (mg/kg) | Transpiration rate (mmol @) m2/s) | Incidence of yellowing （%） |
| Treatment of 1 | 36.36±1.64c | 8.47±0.03c | 0.07±0.01c | 202.00±1.60c | 3.22±0.12b | 20.5± 0.35a |

As can be seen from the table 1, the special conditioner for wine grape yellowing has an obvious effect of increasing the chlorophyll content of wine grapes by 35.70% compared with the condition of not applying micro-fertilizers, and meanwhile, the special conditioner obviously increases the photosynthetic property of the wine grapes, reduces the yellowing rate of a wine grape garden and reduces the yellowing rate from 20.5% to 3.9% compared with the condition of not applying the micro-fertilizers. The yellowing problem of wine grapes can be remarkably improved by combining the spraying and dripping of the special conditioner.
TABLE 2 influence of four treatment modes on the iron content in the wine grape roots, leaves, stems and soil (mg/kg)
| Treatment of | Root of total iron | Total iron of stem | Total iron of leaves | Total iron in soil | Effective iron in soil |
| Process 1 | 146.97±1.73c | 82.75±2.64c | 163.83±2.27c | 1003.00±20.14c | 4.51±0.03c |

As can be seen from Table 2, compared with the treatment without applying the trace element fertilizer, the special conditioner can obviously increase the iron content in the roots, stems, leaves and soil of the wine grapes, particularly the content of the effective iron in the soil is 4mg/kg higher than that of the effective iron in the soil with the chelated iron, the transportation and absorption of the roots and leaves of the wine grapes to the iron are improved, the utilization rate of the iron element in the soil is also improved, and the waste is reduced.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
