What kind of fertilizer do you use to grow grapes? Fertilization methods and matters needing attention of 6 grapevines

In the early stage of grapevine, nitrogen fertilizer was mainly applied, and phosphorus and potassium fertilizer increased correspondingly after entering the fruiting stage, which required about 80-150kg of nitrogen, phosphorus and potassium per hectare except organic fertilizer, which should be properly adjusted according to the variety, yield, tree potential and soil fertility of grapevines, basic fertilizer was applied after winter, and topdressing fertilizer was applied before shade bud, before flowering and during fruit expansion.

In fact, we all know that no matter what is planted, fertilizer is essential for its high yield, but fertilization is also very fastidious, and the fertilizer needed for each plant is different. if improper fertilization not only can not increase production, but will also lead to the death of plants!

What kind of fertilizer is used to grow grapes

In order to obtain high yield, grape needs a lot of nutrients, mainly nitrogen fertilizer in the early stage, and phosphorus and potassium fertilizer increase correspondingly after entering the fruiting period. In addition to organic fertilizer, it also needs about 80-150kg of nitrogen, phosphorus and potassium per hectare, which is adjusted according to the variety, yield, tree potential and soil fertility of grapes. The basal fertilizer was mainly applied after the beginning of winter, with 30,000 kg of chicken and duck manure, 3750kg of cake fertilizer and 3750kg of superphosphate per hectare. Topdressing was applied before shade bud, before flowering and during fruit expansion period, and Zhuangguotiling was sprayed timely. Nitrogen fertilizer was mainly used in the early stage to promote branch growth and flower ear development, and phosphorus and potassium fertilizer was applied to improve quality during fruit expansion period.

Spraying 0. 5% fertilizer outside the root. 3% urea and 0. 5%. 2% potassium dihydrogen phosphate can promote fruit expansion and ripening. In order to produce high quality grapes, the garden needs irrigation facilities to avoid drastic changes in soil dryness and humidity. Generally speaking, more water is needed in budding stage and young fruit growth period, and timely irrigation is needed in case of drought.

The fertilization method is mainly based on solid inorganic fertilizer. According to the needs of grape growth and development, urea is applied 3 times (2 times less than soil cultivation) in the first year of planting, 50 g / plant each time, and 100 g / plant each time. The annual application of urea and ternary compound fertilizer is about 9 kg per mu and 12 kg per mu, which is 5 and 4 times of topdressing per mu, respectively. Among them, the supplement of trace elements adopts the method of foliar spraying, which is combined with spraying about 2-3 times a year.

Due to the vigorous growth and huge root system of grape cultivated in substrate, the ability of resistance to diseases and insect pests was greatly improved. drugs were used about 3-4 times in the first year of planting, as a result, 5 times less drugs were used in the whole growing season of that year. The scaffolding used in grape soilless cultivation is better than the trellis, because the surface of the trellis is short, the grapes grow vigorously, and the fruit setting is not as good as the scaffolding. From the experimental results, the small X shaping with flat shed is not only easy to achieve high yield in the early stage, but also easy to improve the quality.

How to apply fertilizer to grow grapes

1, base fertilizer: mainly organic fertilizer, the amount generally accounts for about 60% of the total fertilizer per mu, stable manure or compost 3000-5000kg per mu, if you choose dried chicken manure sold on the market, the dosage is 700-1000kg, can also be accompanied by the addition of 30kg compound fertilizer, it should be noted that the organic fertilizer must be mature.

2. Topdressing is mainly carried out in the growing period to promote plant growth and fruit development.

3. Sprouting fertilizer: it was applied before the germination of early spring buds, mainly quick-acting nitrogen fertilizer, and irrigated immediately after topdressing to promote sprouting neatly. Urea or mature human feces and urine can be applied, urea 0.1-0.4 kg / plant, and human fecal-urine fertilizer 8-10 kg / plant.

4. Pre-anthesis fertilizer: fertilizing 7-10 days before flowering, it is appropriate to choose nitrogen, phosphorus and potassium compound fertilizer, 0.1-0.15 kg / plant.

5. Fruit expansion fertilizer: in this period, the combination of available nitrogen fertilizer and compound fertilizer should be achieved, urea 0.1-0.5 kg / plant, nitrogen, phosphorus and potassium compound fertilizer 0.1-0.5 kg / plant.

6. fertilizer for increasing color and sugar: refers to the fertilizer applied before or at the initial stage of fruit color change, mainly phosphorus and potassium fertilizer. Potassium sulfate 0.2-0.4 kg / plant can be selected.

Matters needing attention for fertilization of grapes in autumn

1. The base fertilizer must be fully mature before it can be applied, otherwise it is likely to cause root burning, especially chicken manure and sheep manure.

2. Avoid harming the sturdy roots when opening ditches.

3. The lack of elements, especially some trace elements, can be properly added according to the soil conditions in the garden.

4. Water thoroughly at one time after fertilization.

5. According to the appropriate amount of fertilizer application, in general, about 4000 kg of base fertilizer can be applied in high-yield orchards for more than three years, and 5000 kg more under certain conditions.

6. It should also be noted that fertilization should not be applied to one place every year, which can easily cause root system growth to be blocked and rot and die.

Basic principles of fertilization for grapes in autumn

1. It is necessary to use thoroughly mature organic fertilizer, biological bacteria organic fertilizer or biological agent;

2. Do not use irrigating fertilizer containing trace elements.

3. According to the characteristics of soil, choose to use acidic or alkaline fertilizer;

4. Organic calcium fertilizer can be used to regulate soil acidity and basicity.

5. Seaweed fertilizer, chitin fertilizer, amino acid fertilizer and humic acid fertilizer can be used to repair soil.

6. the integration of fertilizer and medicine, while applying fertilizer, kill harmful bacteria in the soil and underground pests, and reduce the occurrence base of diseases and insect pests in the coming year.

Although fertilization sounds like a relatively simple thing, it still takes a lot of energy to do it well. First of all, we should find the right fertilizer for grapes, the second is to find the right time to apply fertilizer, and the third is to find the right part of fertilization, only when all are right, can we achieve the desired results, otherwise it will go in the opposite direction!
