Basal fertilization for grapes in autumn is very beneficial to the growth of grapes. Early application of base fertilizer can cause the accumulation of nutrients in the grapevine in advance, and is conducive to the healing and growth of roots, so as to play the role of bio-organic fertilizer to conserve land as soon as possible. To lay the foundation for subsequent grape growth.

Fertilization time and method

With regard to the time of Shijifei, in general, early and mid-maturing grapes can be applied after harvesting, late-maturing grapes can be applied before harvesting, and it is better to finish late in early October.

The first method of applying basal fertilizer is ditching. Usually along the planting line ditch. If the basal fertiliser is applied for the first time after planting, a groove 30 cm wide and 60 cm deep can be opened along the planting furrow. When the ditch is opened, the topsoil and raw soil are opened. Before fertilizing, backfill a layer (about 10 cm) of topsoil, apply base fertilizer, and fill the topsoil. Then, the soil and the fertilizer are stirred again, and finally, the raw soil is backfilled into the ditch, and the remaining soil is used as a hoe for easy watering. The second is appendage. This method is commonly used in the old vineyards, which is to spread the base fertilizer between the rows of grapes and then plow. This method has the advantage of saving time and money. The disadvantage is that the fertilization is too shallow and the amount of fertilizer needs to be increased.
