First, the benefits of the autumn base fertilizer can increase the accumulation of nutrients in the tree. Second, it is conducive to the healing of roots and the emergence of new roots. The third is to avoid soil drought caused by fertilization. The fourth is to make the base fertilizer play the fertilizer effect in a timely manner.
Second, the application of the base fertilizer time Generally speaking, the early and middle-aged grapes can be applied after harvesting, and the late-ripe grapes can be applied before harvesting, and it is better to apply them at the latest in early October.
Third, the 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, it can be opened outside the planting ditch: a groove 30 cm wide and 60 cm deep. When ditching, the topsoil and the raw soil are open. Before fertilizing, first fill a layer of topsoil (about 10 cm), then apply the base fertilizer and fill the topsoil. Then, the soil and fertilizer are stirred all over, and finally backfilled with raw soil to the ditch, and the remaining soil is used for watering. The second is the application. This method is commonly used in old vineyards. The basic fertilizer will be spread among the grape rows, and then ploughed. The advantage of this method is that it saves labor and time, and it has a wide range of fertilizers. The disadvantage is that the fertilization is too shallow and the amount of fertilizer needs to be increased.
Fourth, several problems that should be noted First, the base fertilizer must be decomposed and applied, especially chicken manure. The second is to avoid hurting the roots. Third, according to the fertilizer content of the soil in the garden, the lack of elements, especially some medium and trace elements. Fourth, you must pour water once after fertilization. The fifth is to discretion the amount of fertilizer applied. Generally speaking, vineyards with a yield of 2,000 to 3,000 kilograms per mu can be used for 4,000 to 5,000 kilograms of base fertilizer, and 10,000 to 15,000 kilograms can be applied for conditions. Sixth, the scaffolding is fertilized, and it is necessary to dit the fertilization from the inside out in the direction of vine growth. Seventh, the base fertilizer can not always be applied in one place, which is easy to cause root growth to be blocked and rot and die.
