Applying the base fertilizer to the grapes in the autumn is beneficial to the growth of the grapes. Applying the base fertilizer in advance can start accumulating nutrients in the vines in advance, and is beneficial to root healing and growth, and the effect of bio-organic fertilizer to protect the land as early as possible. Lay the foundation for subsequent grape growth.
Fertilization time and method
Regarding the time of applying the base fertilizer, in general, the early and middle-ripening grapes can be applied after harvesting, and the late-ripening grapes can be applied before harvesting, and it is better to apply them at the latest in early October.
The first method of applying the base fertilizer is a groove-like application. Generally, it is applied along the colonization line. If the base fertilizer is applied for the first time after planting, a groove 30 cm wide and 60 cm deep may be opened outward along the planting ditch. When ditching, the topsoil and raw soil are open. Before fertilizing, first backfill a layer of topsoil (about 10 cm), then apply the base fertilizer and fill the topsoil. Then, stir the soil and fertilizer again, and finally backfill the soil with the raw soil to the ditch, and the remaining soil is used for watering. The second is to give. This method is commonly used in old vineyards. It is the basic fertilizer that is spread among the grape rows and then ploughed. The advantage of this method is that it saves labor and time, and it is widely affected by fertilizer. The disadvantage is that the fertilization is too shallow and the amount of fertilizer needs to be increased.
Fertilization considerations
First, organic fertilizer must be decomposed after application, especially chicken manure.
Second, to avoid hurting the roots.
Third, according to the soil fertilizer content of the garden, the lack of elements, especially some medium and trace elements.
Fourth, must be poured once after fertilization.
5. Discretionary fertilization amount. Generally speaking, vineyards with an annual yield of 2,000 to 3,000 kilograms can be used for 4,000 to 5,000 kilograms of base fertilizer, and 10,000 to 15,000 kilograms can be applied to conditions.
Sixth, scaffolding fertilization, along the direction of vine growth year by year from the inside out of the ditch fertilization.
Seventh, the base fertilizer can not always be applied in one place, it is easy to cause root growth to be blocked and rot and die.
