Potted grapes should be large ash pots 30-40 cm in diameter, or wooden boxes. Potted earth can be made up of 4 parts of humus, 5 parts of sandy loam soil and decomposed chicken manure, and 1 part of bean cake. To select the strong seedling pots that are short 1-2 years old among the internodes. After the basin, use a bamboo pole to erect the bracket. General seedlings can only leave one main stem. When they grow to 50 centimeters in height, they need to be plucking their hearts to promote their lateral growth. When side vines grow 3-4 leaves, then take heart again. After many times of picking up, the mother stem with a thick main stem and full side winter buds can be cultivated.
During the grape growing period, sufficient sunshine and ventilation are needed. The water supply should be sufficient. In spring and autumn, water can be poured once a day. In summer, it can be poured once every afternoon (water must be used after sun exposure, and cold water should not be used). During the rainy season, attention should be paid to the elimination of water in the basin. Fertilizer in addition to the foot base fertilizer, can be applied three times a year forced fertilization: flowering before the application of more cake fat; fruit during the application of cake fertilizer and phosphorus and potassium fertilizer; July cake fertilizer applied again in order to promote the second result. During the fruit coloring period in August, some additional phosphorus and potassium fertilizers may be applied. When fertilizing, you must loosen the soil and then water it. In order to make the vine grow robustly and produce many results, the vines must be pruned correctly and promptly. Pruning in winter should be carried out during the dormancy period in winter, but not later than before sprouting in spring. Summer pruning is carried out at any time during the growth period, and is mainly for removing buds, picking up the heart, removing tendrils, and picking up leaves. The result is to maintain a certain distance between the branches so that the vine spreads evenly. New shoots with no spikes are tipped when they grow to 5-6 pieces. For the old and weak result mother branch, care should be taken to keep the reserve branch and keep it as close to the main vine as possible, so as not to raise the result branch. The root system of the grape is well-developed, and it is easy to root around the pot. It must be turned once a year after autumn to replace the new soil and cut out the old roots. The roots need only to be cut to a depth of 1 cm at the periphery, and the root can not be destroyed.
The major diseases and pests of grapes include blackpox, anthrax, white rot, red spider, and scale insects. At ordinary times, thiophanate-methyl 1000-fold or 1:0.7:200 Bordeaux-containing fluid can be sprayed once every half month to 20 days. After pests and diseases are discovered, they can be sprayed with 1000-fold Daisen ammonium solution or 75% chlorothalonil wettable powder 600-800 times.
