In order to prevent the phenomenon of minor years in grape growing, fruit growers should grasp the following aspects in winter management:
First, highlight the basal fertilizer and set it up with fertilizer. Grape yield and fertilizer levels are positively correlated. The intrinsic experience is: to set the output by fertilizer, or to produce fertilizer. In general, for every 500 kilograms of grapes produced, 1,000 kilograms of organic manure must be decomposed with high quality, and phosphorus and potash fertilizers should be used in combination. In basal fertilizers, the amount of nitrogen fertilizers accounts for 60% to 70% of the whole year, phosphate fertilizer accounts for more than 80%, and potassium fertilizer accounts for 30% to 40%. Advocate to cover the straw on the ground of the vineyard. The thickness of the cover grass is about 20 centimeters. It can keep warm and protect the weeds, inhibit the weeds, and the soil can be improved after the straw rots. In the newly-built vineyards, the first step is to dig trenches and planting trenches, the width of the trenches is 60 cm, and 3000 to 5,000 kg of decomposed organic fertilizers are applied to the vineyards. After blending with the fine soil, the base fertilizer is evenly mixed, and the trench is filled with a layer of topsoil. Plant seedlings to lay the foundation. Of course, in addition to basal fertilization, before the sprouting of the grapes, before flowering, and before fruit setting, it is also necessary to top-coat fertilizers and spray fertilizers outside the roots.
Second, control the retention of the mother, update the main vine. The grapes are put into dormancy and winter pruning begins. The pruning is done before leaves fall to the beginning of spring. Pruning is divided into short cuts and updated cuts. The short cut is for the main vine, and the update is for the old vine. The short shearing time had 8-12 buds, 5-7 buds, and 2-3 buds. The type of buds with high parts of the berry was mainly the medium and short vines. To update the pruning, the first step is to selectively cultivate the vigorous shoots of the Minister of Grapes. When the new shoots of the new shoots grow more fruit, they will cut out the senile vines; the second is to update the berry seedlings. Stay strong, stay on and stay before.
Third, clean up the debris and reduce the source of the disease. In the winter, it is necessary to thoroughly clean up the vineyards. First, we must clean up the remaining foliage; second, we must remove the disease; third, we must remove the weeds, and then concentrate on deep-buried or burned. Before the sprouting of the grapes, it is necessary to use Baume's 5 degree lime sulfur agent to thoroughly spray the vine, stems, and soil 1 or 2 times to kill germs and reduce the incidence of the next year.
