How to use foliar fertilizer for grapes, what foliar fertilizer to use on the foliar surface during

The high-efficiency compound nutrition preparation imported from Italy contains high-efficiency chelated calcium, magnesium, copper, iron, manganese, zinc, boron, molybdenum, high-tech active titanium and photosynthetic-promoting substances, which has a very high bioavailability rate and is dozens of times more effective than general chelated trace elements.

Features & Benefits:

1. It is used for yellowing, leaflets, leaf rolls, mosaic leaves caused by physiological diseases, stunted growth and development, and element deficiency.

2. Crops need to be applied in time when they are subjected to adversity stress (such as high temperature, drought, flood, low temperature, bacterial infiltration, etc.). Its special formula makes it unique against viral diseases and other diseases.

3. Make the leaf surface dark green, the root system is strong, promote the differentiation of flower buds, preserve flowers and fruits, promote the expansion (fruit) seeds, and significantly improve the quality while greatly increasing the yield, so that the fruit is full, upright, beautiful in color, and the sugar content is increased.

How to use and dosage:

1.Foliar fertilization:

Vegetables:Dilute 3000 times of liquid at the seedling stage, and dilute 1500-2000 times in the middle and late stages and spray on the front and back of fruits and leaves.

Fruit Trees:Dilute 2000-3000 times and spray on the front and back of fruits and leaves.

2.Drip irrigation, root irrigation:Dilute 2500-3000 times the liquid and apply, the dosage per mu does not exceed 250 grams, and does not exceed three times a year.

3. Chongshi:Dilute 3000-4000 times of the liquid and rinse it with water. The dosage per mu shall not exceed 300 grams, and shall not exceed three times per year.

Notes:

1.The spraying time should avoid high temperatures, and after application, there is no need to apply other trace element foliar fertilizers.

2. This product has strong mixability, and can be applied at the same time with nitrogen, phosphorus, potassium, fungicides, and insecticides, but it is easy to be diluted separately and added, and cannot be mixed directly.

3. This product has super solubility, and it is easy to absorb moisture in the air and produce agglomeration, but it will not have any effect on its quality.

1. Spray once at the young fruit stage and once at the swelling stageSpray selenium-rich foliar fertilizer；Choose a sunny or cloudy day to spray at about 4 o'clock in the afternoon (at this time, the light and temperature are suitable, which is conducive to crop absorption; If sprayed in the scorching sun and high temperature period, the water evaporates quickly, resulting in an increase in fertilizer concentration, crops can not absorb, and even fertilizer damage may occur) foliar spraying of the whole plant, such as rain 24 hours after spraying, and then spray again;

Dosage per mu: about 1-2 bottles, 100-200 times with water for foliar spraying, and drones with water 10-20 times for foliar spraying. Spray 2 times throughout the period.

2. Field management: the same as ordinary orchard management.

1. Spraying needs to be carried out on sunny days, but spraying should be avoided when the sun is exposed to avoid burning crop leaves; If it rains 4 hours after spraying, you need to respray again;

2. Spraying "spraying fu" foliar selenium silicon fertilizer can only be harvested after spraying for at least 7 days;

3. When spraying "spraying fu" foliar selenium silicon fertilizer, it needs to be used separately, and should not be mixed with other foliar fertilizers, pesticides and herbicides, so as not to affect the fertilizer efficiency and possible pesticide damage.

1. Greatly reduce the content of heavy metals in grapes. After application in moderately and mildly polluted land, it can reduce the cadmium uptake of grapes by 20%-50% and the arsenic uptake by 20%-30%.

2. Effectively improve grape yield. Promote the photosynthesis of crops, enhance the growth and development of roots and the effective use of nutrients, and increase the yield of melons and fruits by 10%-20%.

3. Reduce pesticide residues in grapes and inhibit nitrate absorption. Improve the resistance of grapes to stress, diseases and pests.

Hope it helps

Direct spraying is more common. Look at the content and usage. Do not use it indiscriminately, it will cause drug damage.

It should work. <>

Summary. Are you there? Most growers will choose the former to fertilize when they can grasp the concentration and dosage, and the latter special fertilizer is more common in recent years, which fully meets the nutrient needs of grapes in the middle and late stages of growth.

What foliar fertilizer to use on the foliar surface during the grape expansion period.

Are you there? Most growers will choose the former to fertilize when they can grasp the concentration and dosage, and the latter special fertilizer is more common in recent years, which fully meets the nutrient needs of grapes in the middle and late stages of growth.

The dosage of grape foliar fertilizer is generally tens of grams of powder or liquid fertilizer per acre, and the amount of water is about 40 kilograms, which is calculated according to the dilution ratio of the fertilizer used. The number of fertilization, during the grape expansion period, foliar spray top dressing is applied once for more than 10 days, two or three times in a row.

The appearance of many transparent droplet-shaped balls on the grape stem is a nutrient overabundance of grapes that have gathered into nutrient beads, indicating that the grapes are nutrient-rich and do not need to be fertilized.

Sou Lixiang Precautions for grape planting:

The planting thickness is generally more than 80-100, the burial permeability of the clay soil is poor, easy to compact, the grape root system is shallow, the production is weak, the fruit is poor, sometimes the yield is large but the quality is poor, and the planting of Portuguese grapes on heavy clay soil should generally be avoided. Grapes are more salt-resistant plants in fruit trees, and grapes can grow well in places where fruit trees such as apples and pears cannot grow. However, in soils that are too acidic (pH close to 4), growth is significantly poor, and in relatively alkaline soils (pH), yellow leaf disease begins to appear.

Grapes need a lot of nutrients, and nitrogen fertilizer is the main fertilizer in the early stage, and phosphorus and potassium fertilizer increase correspondingly after entering the fruiting period.
