Summary: Do grapevines need fertilization in winter? How to apply fertilizer?

Do grapes need winter fertilizer? Many friends do not attach importance to this, or even do not think so, scientific agriculture that winter fertilizer is still very necessary. From autumn grape leaves fall to the next year germination period, basically is the grape dormant energy accumulation stage, we may have seen peony, planting too late or field fertility thin words even do not bloom, and this phenomenon is also very obvious in grapes, typical less flowers, less fruit, so winter supplement winter fertilizer can effectively improve the quality and yield of grapes in the coming year.

top dressing time

Fertilization can be carried out before winter, and topdressing should be carried out roughly in November, not too early or too late. Early words, fertility may be consumed in advance, and generally grapes in summer and autumn usually more adequate topdressing, just when the leaves are more fertile, so there is no need to apply topdressing too early. If it is too late, it will cause the grapes to fail to accumulate enough nutrients. And if faced with a lack of phosphorus and potassium, the resistance may not survive the winter.

What fertilizer?

In winter, grapes are dormant and have little need for nutrients, but few does not mean they do not need them. After all, plants still need to maintain their life activities. Since leaves are not growing, there is very little need for nitrogen fertilizer. Excessive nitrogen fertilizer will also lead to vigorous growth in the coming year, while phosphorus and potassium fertilizer are still needed to improve the disease resistance of grapes.

Generally speaking, farm manure is the best, of course, decomposed farm manure. It contains three major elements of nitrogen, phosphorus and potassium as well as many mineral elements, which can meet the growth needs of plants. Of course, you can also choose to consider organic fertilizers sold in the market. However, the price was relatively high.

If you choose chemical fertilizer, then it is recommended to consider phosphorus and potassium fertilizer, such as potassium dihydrogen phosphate or calcium superphosphate + potassium chloride (potassium sulfate) scheme, and the lowest also to apply calcium fertilizer, ordinary demand for calcium is still relatively large, at this time chasing some calcium superphosphate is also very beneficial.

How to fertilize?

Organic fertilizer or farm manure should be applied by deep tillage. If the surface is fertilized, nutrients are difficult to be absorbed by plants. Moreover, organic fertilizer or farm manure can be further decomposed by deep tillage, accelerating the release of nutrients and improving utilization efficiency. Grape roots are relatively deep, so it is recommended that they be deeper when fertilizing.
