What fertilizer should be applied to grape seedlings in the first year (what fertilizer should be used to make newly planted grape seedlings grow faster)

Grapes are woody vines with spherical or oval fruits. Grapes grow vigorously and bear a lot of fruit. They require a lot of fertilizer, nitrogen and potassium. They are potassium-loving crops. At the same time, they also have a lot of calcium, iron, zinc, manganese, etc. What fertilizers should we mainly apply to one-year-old grape seedlings?

Fertilization stage of grapes in the first year of planting (picture)

1. Base fertilizer: Fertilizer applied to improve the soil.

When applying base fertilizer to the orchard, use farmyard manure or microbial fertilizer as the main method. Farmyard manure, such as chicken manure and pig manure, can not only improve the fertility of the soil, but also lay a good foundation for the growth of fruit trees.

Microbial fertilizers can quickly replenish the nutrients of crop roots, guide the transfer of nutrients to the roots and promote rooting. They can also improve the crop's resistance to stress and quickly eliminate the adverse effects of harsh environments on crops.

When applying top dressing, the first thing to apply is germination fertilizer, that is, when the grape vines have just sprouted, germination fertilizer is applied in the early stage of germination.

① You can choose a 20-20-20 water-soluble fertilizer with a balanced nitrogen, phosphorus and potassium content, with a usage of 10kg-15kg per mu.

② If conditions permit, choose Green Oasis Root Song, a package fertilizer containing humic acid, at 8-10kg/mu. The advantage is that it can fully supplement the elements needed by grapes, while also increasing ground temperature and promoting early germination of grapes.

2. Fertilizer before flowering

This top dressing is mainly for root fertilization in weak tree gardens, but nutrients such as boron, zinc, and iron must be supplemented by spraying.

① Boron, zinc, iron and other nutrients should be supplemented on the leaves as early as possible. You can dilute Green Oasis foliar fertilizer 500-800 times and spray it 1-2 times.

② If the tree is weak, dilute Green Oasis Root Song 200-300 times per mu + Root and Seedling 1500-2000 times per mu, and use it half a month before flowering.

Supplementing boron, zinc and iron fertilizers before flowering is beneficial to pollen formation, reduces fruit size and ensures quality. At the same time, for weak trees, it can enhance tree vigor and increase fruit set rate.

3. Fruit-enlarging fertilizer

After the grapes are set, when the fruit is about the size of mung beans and later the size of soybeans, apply fertilizer. This fertilizer is mainly composed of phosphorus, potassium and calcium. The amount of fertilizer should be large, accounting for about 50% of the annual fertilizer application.

① If calcium fertilizer is insufficient, pay attention to supplement calcium fertilizer 1-2 times. Per mu, you can spray Green Oasis foliar fertilizer 100ML/bottle diluted with 500-800 times water and spray evenly.

② Apply 8-10kg of Green Oasis 20-20-20 Balanced Type per acre by flushing or drip irrigation. If used for drip irrigation, apply small amounts and multiple times. The amount used can be increased or decreased based on your own garden management and yield.

4. Color-changing and enlarging fertilizer

The fruit color change period is crucial in the annual grape management process. Potassium fertilizer can promote the color change of the fruit and the accumulation of sugar. Top dressing should be started before the fruit softens and begins to change color .

① Apply high potassium 10-9-40 Green Oasis Fruit Beauty water-soluble fertilizer during the first expansion period of grapes (young fruit stage to hard core stage) and the second expansion period (hard core stage to early color change), with each application amount of 10-12kg.

② Apply Green Oasis to the roots to ensure roots and seedlings. You can also spray it with 1500 times the amount of water to increase color and sweeten the scent, making it delicious.

This period is an important period for grape coloring, sugar content increase, and organic matter accumulation. Potassium fertilizer can effectively promote sugar increase and coloring, but different potassium fertilizers have different properties, so it is necessary to correctly understand the types and amounts of potassium fertilizers.

5. Postpartum fat

After the grapes are harvested, apply fertilizer once to restore the tree vigor, protect the leaves, promote flower bud differentiation and increase the amount of flower bud differentiation, laying the foundation for a good harvest the following year.

(1) Use drip irrigation or flushing to apply 500-800 times of Green Oasis Root Fertilizer per acre to improve the soil, promote the growth of grape roots, and facilitate the differentiation of flower buds in the second year. Repeat 2-3 times and pay attention to the prevention and control of leaf diseases.

This can increase the chlorophyll content of the leaves, improve photosynthesis capacity and prevent early leaf fall.

(2) Use 8-10kg of Oasis Balanced 20-20-20 water-soluble fertilizer per mu to restore the tree vigor.

In short, scientific fertilization plays a key role in increasing grape production. If you master this fertilization plan and combine it with refined management, I believe that this year's grapes will definitely have a high yield.
