Grape growth of the most complete fertilization technology, 5 times fertilization critical period should not be missed!

Grape is a fertilizer-loving fruit tree. In a growing season, the content of nitrogen, phosphorus and potassium required by different growth periods is also different. Due to the influence of climate, fertilizer and water and improper management measures, fruit cracking, brown spot and yellow leaf disease often occur in vineyards. How to apply fertilizer reasonably in order to improve the soil conditions of grape growth and lay a good foundation for sustainable high yield and high quality? Mastering the five most important fertilizers in grape growth is the most important lesson for every grape grower!

First, promote budding and fertilize

It is generally applied before grape germination, this time with nitrogen fertilizer (a large number of element water-soluble fertilizer is appropriate), the purpose is to promote neat germination, thick leaves, large and strong inflorescences. If the trees are too strong and the spring is not very dry, the fertilizer and water can be saved this time so as not to cause new shoots to grow.

It is suggested that the balanced water-soluble fertilizer should be used to effectively improve the nutrient imbalance in farmland, especially the best effect on soil de-fertilization, which can meet the nutritional needs of grape during the whole growth period and has a wide range of application. Available nitrogen, phosphorus and potassium can facilitate crop absorption and utilization, rapidly strengthen seedlings, enhance photosynthesis, promote grape branch sprouting, rapid growth, and correct the symptoms of weak crop growth. It is rich in boron, iron, manganese, zinc, copper, molybdenum and other trace elements, which can quickly correct the symptoms of element deficiency in grapevines, improve crop resistance, enhance quality and increase yield. Low salt accumulation, long-term use is not easy to cause soil salinization, does not cause environmental burden on the soil, and ensures the recycling of the soil.

Application suggestion: it can be applied at any time during the vegetative growth period of grapes.

Foliar spraying: dilution 800-1200 times, dosage per mu 20-30g/ times, 7-10 days / time.

Drip irrigation: 1-3kg/ per mu, 15-45kg/ per hectare, 7-10 days per time.

Irrigation: 3-6kg/ times per mu, 45-90kg/ times per hectare, 10-15 days per time.

II. Inflated fat

After the fruit of the grape is set, the fruit is as big as mung bean and applied when it is as big as soybean at night. This time, nitrogen is the main fertilizer, and phosphorus and potash are applied at the same time. High nitrogen compound fertilizer or ordinary three-element compound fertilizer can be applied, and urea and other nitrogen fertilizer can be added as appropriate. This period is when a large amount of fertilizer is needed, which can account for about 50% of the amount of chemical fertilizer applied in the whole year. It is suggested to combine the application of rich eugenol and high potassium humic acid water-soluble fertilizer and Bonlilong high potassium humic acid water-soluble fertilizer, so as to provide sufficient nutrients for grape growth and promote fruit expansion and nutrient accumulation.

In this period, special attention should be paid to the supplement of calcium fertilizer. Calcium is a necessary medium element for crop growth. The lack of calcium often leads to the decrease of crop yield, the decline of quality and the aggravation of diseases. For example, although grape fruit cracking has something to do with overwatering during ripening, the thin skin and poor elastic toughness of grape fruit are also one of the reasons due to the lack of calcium. The imbalance of nutrition after calcium deficiency will also affect the accumulation of sugar, less fruit powder and light flavor; the fruit is easy to soften and fall off and uneven in size, easy to drop and crack, and the storage life and shelf life are shortened.

Burson plasma calcium fertilizer is recommended because of the use of international cutting-edge low-temperature plasma technology, which opens the calcium channel of crops, greatly improves the absorption and utilization of calcium, enhances the stress resistance of crops while replenishing calcium, and effectively enhances the resistance of crops to drought, salt injury, freezing injury, sunburn, diseases and insect pests.

Application suggestion: it is suggested that the foliar should be evenly sprayed with water diluted 1500-2000 times, every 7-10 days, continuously spraying 3-4 times. The concentration of calcium deficiency can be increased appropriately in the period of young fruit and fruit expansion. During drip irrigation, 2000-3000 times dilution can also be applied with water, and the dosage can be adjusted appropriately according to crops.

III. Ripening fertilizer

Do it in two stages. 20-30 days before ripening, high potassium water-soluble fertilizer was applied, and once more fertilizer was applied when the grape berries began to soften and before coloring.

Fertilization is very important this time. After applying expansive fertilizer, many fruit growers no longer apply ripening fertilizer, or cause fruit color change (commonly known as water pot disease) or lack of fertilizer, grape resistance is poor, easy to get disease, high yield but not good harvest. Or poor coloring, low sugar content, not a good price, and so on. Can be directly applied to functional fertilizer, a large number of elements water-soluble fertilizer color (recommended high phosphorus and high potassium type, while containing trace elements boron and zinc). During this period, it is recommended to use rich eugenol and high potassium water soluble fertilizer and Bonilong Chong Shuo high potassium humic acid water soluble fertilizer.

The high potassium formula of rich and high potassium water-soluble fertilizer is suitable for grape after fruit seding. it can reduce fruit drop, reduce deformed fruit, make the fruit uniform, expand quickly, color quickly, smooth and shiny skin, and increase sweetness. it can not only improve the yield but also improve the quality. Dosage: diluted 1000 to 1500 times. Spray evenly on the front and back of the crop, spraying fertilizer 15 grams per barrel of water (15 liters) for 3 times every 7 to 10 days. The amount of drip irrigation was 1-3kg/ per mu, 7-10 days per time, and that of irrigating application was 3-6kg/ per mu, 10-15 days per time.

On the other hand, Bonilong Chong Shuo high potassium humic acid water-soluble fertilizer can enhance the synthesis and transportation of enzymes to sugar, starch, protein, fat and various vitamins, stimulate the activity of polysaccharides and transform polysaccharides into soluble monosaccharids. so as to improve the sweetness and quality of grape fruit. Dosage: 5kg per mu.

Fourth, "Yuezi Fat"

Refers to the grape harvest, pay close attention to the application of fertilizer, usually a large amount of element water-soluble fertilizer (high nitrogen type) 15 kg, combined with the application of compound microbial fertilizer. The effect of this fertilizer is not only used to restore tree potential, but also to promote flower bud differentiation, laying the foundation for high yield in the following year.

Banglilong compound microbial fertilizer is rich in all kinds of nutrients needed for plant growth, as well as organic matter and a large number of beneficial microorganisms. at the same time, the use of plasma strain activation technology can effectively improve the activity of beneficial bacteria and increase the number of bacteria. regulate the resistance of trees. At the same time, the content of chlorophyll was increased, the leaf color was thick and green, the stem was strong, and the yield was significantly increased. Usage: either irrigation or drip irrigation. 20 kg / mu and 10-15 kg / mu at seedling stage.

5. Overwintering fertilizer

The traditional method is to apply grapes during dormancy. In recent years, it is advocated to apply in August and September, and in the period of green branches and green leaves after grape harvest. At this time is the second peak of grape root growth, can promote grapes to produce a large number of fibrous roots, in order to strengthen the tree momentum, more conducive to overwintering. This time the fertilizer is made of organic fertilizer (if farm manure is used, please be careful that it must be mature! ), apply calcium fertilizer at the same time, or add a small amount of three elements.

According to the peak of grape root growth, root-strengthening products can be applied, such as agricultural plasma preparation root application or root maintenance experts, which can effectively promote grape root growth and improve the absorption and utilization of root nutrients. Its core component, low temperature plasma technology, can significantly improve tree potential and resistance, reduce the occurrence of diseases, and create a good root growth environment for grape growth. The amount of root application type: 1-2 bags per mu (20kg); the amount of root maintenance experts: 1 barrel per mu (5kg).

It is suggested to choose plasma organic fertilizer for the use of organic fertilizer. compared with ordinary organic fertilizer, low temperature plasma technology can activate organic fertilizer and transform difficult-to-use organic matter into active state, so it can improve soil permeability and increase the content of organic matter in soil. significantly improve the absorption and utilization of fertilizers, fundamentally provide nutrient guarantee for crop quality improvement and efficiency, and meet the production needs of organic high-quality agriculture. Dosage: 5-8 bags per mu (40kg)

Note: after each fertilization, should be irrigated once permeable, the amount of water is not the bigger the better, too large, resulting in fertilizer and water loss. After the expansion fertilizer is applied, it should be watered continuously, with an interval of 5-7 days.

In addition, grapes should be watered once before overwintering, and ploughed once after the soil is loose, which is extremely good for anti-freezing.

Understand the most important five fertilization periods in grape growth, master this set of fertilization scheme, and cooperate with fine management, like a tiger with wings, will certainly achieve fruitful results. I believe you can become a master of grape cultivation!
