One of the benefits of autumn basal fertilizer is to increase the accumulation of nutrients in the tree body; the second is to facilitate root healing and new roots in the scald; the third is to avoid soil drought caused by fertilization; and the fourth is to make basal fertilization timely.
Schiff-fertilizer time Generally speaking, 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 the first half of 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.
One of the first problems that should be noted is that the basal must be decomposed, especially chicken manure. The second is to avoid hurting the thick roots. The third is based on the fertilization of the soil in the garden, and the elements that are lacking in the berry, especially some trace elements. Fourth, it must be poured once after fertilization. The fifth is to determine the amount of fertilizer. Generally speaking, the annual yield of 2000-3000 kilograms of vineyards, base fertilizer can be applied to 4,000 to 5,000 kilograms, conditions can apply up to 10,000 to 15,000 kilograms. Sixth, the scaffolding is used for fertilizing. It is necessary to fertilize the vines in the direction of vine growth year by year. Seventh, basal fat can not always be applied in one place, and it is easy to cause the growth of roots to be impeded and rot to die.
