What Fertilizer to Use for the First Year Grape Seedlings
A bit of knowledge to share with you about the introduction of green plants and flowers on what fertilizer to use for the first year grape seedlings, the specific contents are as follows:
What Fertilizer to Use for the First Year Grape Seedlings
When applying base fertilizer to the orchard, use mainly farm manure or microbial fertilizer, such as chicken manure or pig manure. After the grapes have set fruit, when the berries are the size of mung beans to soybeans, apply the fertilizer. This time, the fertilizer should be mainly composed of phosphorus, potassium, and calcium. Then, during the fruit coloring stage, potassium fertilizer can promote the coloring of the fruit and the accumulation of sugars, which is crucial in the annual grape management process.
Grapes are woody vines with spherical or oval fruits. Grapes grow vigorously, produce a lot of fruit, and require a large amount of fertilizer, especially nitrogen and potassium, making them potassium-loving crops. They also require a lot of calcium, iron, zinc, manganese, and other nutrients. So, what kind of fertilizer do we mainly apply to one-year-old grape seedlings?
The Fertilizing Stage for the First Year of Planting Grapes
1. Base Fertilizer: Fertilizer applied to improve soil.
When applying base fertilizer to the orchard, use mainly farm manure or microbial fertilizer, such as chicken manure or pig manure, which can not only improve the fertility of the soil but also lay a good foundation for the growth of fruit trees.
Microbial fertilizer quickly supplements the root nutrition of crops, guides nutrients to the roots, promotes root growth, and can also enhance the plant's resistance to stress, quickly eliminating the adverse effects of harsh environments on crops.
For topdressing, the first one is the bud-promoting fertilizer, which is applied when the grapevines are just beginning to sprout, in the early stage of sprouting.
① You can choose a balanced 20-20-20 water-soluble fertilizer, with an application rate of 10-15 kg per mu.
② If conditions allow, use a humic acid-containing complete fertilizer like Green Oasis Root Praise 8-10 kg/mu, which can comprehensively supplement the elements needed by grapes and also increase soil temperature, promoting early sprouting of grapes.
2. Flowering Fertilizer
This topdressing is mainly for weak trees and focuses on root application, but boron, zinc, iron, and other nutrients must be sprayed and supplemented.
① Boron, zinc, iron, and other nutrients should be supplemented early, using 500-800 times diluted Green Oasis foliage fertilizer sprayed 1-2 times.
② For weaker trees, apply Green Oasis Root Praise diluted 200-300 times and Green Oasis Root and Seedling diluted 1500-2000 times, half a month before flowering.
Supplementing boron, zinc, and iron before flowering is beneficial for pollen formation, reducing fruit size differences, ensuring quality, and for weak trees, it can enhance tree vigor and improve fruit-setting rate.
3. Fruit Swelling Fertilizer
After the grapes have set fruit, when the berries are the size of mung beans to soybeans, apply a fertilizer mainly composed of phosphorus, potassium, and calcium. This amount of fertilizer should be large, accounting for about 50% of the annual application.
① If calcium is insufficient, pay attention to supplementing calcium 1-2 times, applying Green Oasis foliage fertilizer 100ML/bottle diluted in 500-800 times water evenly.
② Apply 8-10 kg of Green Oasis 20-20-20 balanced water-soluble fertilizer per mu through irrigation or drip, and if using drip, apply in small, frequent doses; adjust the amount according to the management and yield of your orchard.
4. Color Change and Swelling Fertilizer
The fruit coloring stage is crucial in the annual grape management process. Potassium fertilizer can promote fruit coloring and sugar accumulation, starting to apply topdressing before the fruit softens and begins to change color.
① Use high-potassium 10-9-40 Green Oasis Fruit Beauty water-soluble fertilizer, applied during the first and second fruit swelling stages, each time with an application rate of 10-12 kg.
② Apply Green Oasis Root and Seedling to the roots, and also spray diluted 1500 times for better coloring and sweetness.
This period is crucial 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 and the type and amount of potassium fertilizer need to be correctly understood.
5.月子肥 (Post-Harvest Fertilizer)
After grape harvesting, apply a fertilizer to restore tree vigor, protect leaves, promote flower bud differentiation, and increase the amount of flower bud differentiation, laying the foundation for high yields the following year.
Apply 500-800 times diluted Green Oasis Root Praise bacterial fertilizer per mu through drip or irrigation to improve soil and promote grape root growth, which is beneficial for the second-year flower bud differentiation, applied continuously 2-3 times, and also pay attention to the prevention and control of leaf diseases.
This can increase the chlorophyll content in the leaves, enhance photosynthetic capacity, and prevent early defoliation.
Apply 8-10 kg of Green Oasis balanced 20-20-20 water-soluble fertilizer per mu to restore tree vigor.
In summary, scientific fertilization plays a key role in increasing grape production. Mastering this fertilization plan and combining it with meticulous management, this year's grapes should yield a high harvest.
The comprehensive method explanation for what fertilizer to use for the first year grape seedlings shared above, I hope it can serve as a starting point to solve your green plant problems.
