The management basin for planting potted grapes should not be too small. When the fruit seedlings grow, you can use a smaller pot first, but as the vines grow, the soil and nutrients are too small to keep up. Choose at least one basin with a diameter of more than 30cm. In order to increase air permeability, some coarse sand can be added to the soil.
It is best not to close the basin. I tried to grow a grape in a porcelain basin. For two years in a row, the grapes didn't grow at all. I checked the soil in the basin and found it difficult to dry after watering. After the rain, the basin was filled with mud for a long time. Therefore, it is not conducive to the development of grape roots.
Don't plant two grapes or one grape with other fruit trees and plants. I planted two grapes together, and some small vegetables were planted in the open space next to them. Then this pot of grapes is almost fruitless, and you really can't be greedy. And the weeds inside should be cleaned up.
Don't water it too much. If you put it on the balcony, you must pay attention to this problem. The outdoor one is a little better. Because the balcony itself is not ventilated enough, if the soil is too wet, the evaporation is also small. Grapes themselves can't drink that much water, which will only increase its burden.
When erecting a scaffold, there is no need to use an iron shelf or a shelf with fast heat transfer. Especially in summer, the high temperature at noon will make the grape branches turn red, burn easily, wither the original green vines and turn the leaves yellow.
Fertilization should be increased in the peak season of grape growth. In the spring, I saw an elder sister, who put organic fertilizer in the foam box for growing grapes and cooked her own leftovers. Grapes grow very vigorously and have a lot of fruits. However, at the flowering stage, it will be difficult to let the flowers fall and the fruit not hang if you apply less chemical fertilizer or add more water.
Soil is very important, so loosen it regularly. But be careful not to hurt your roots. If you see the soil in the basin as hard as stone, you should dig out the vines and plant them again. Or replace it with loose, breathable and nutritious humus soil. Add enough decomposed fertilizer as base fertilizer. Grapes will grow well next spring.
If you think the total length of grapes is not good, you can consider changing pots or changing soil. Prune branches in winter. But that large-scale grape base needs pruning. If it is planted at home, it will not grow so luxuriantly. If it's on the terrace or roof, you can trim it a little. Promote more new branches in the coming year.
Pot soil preparation and requirements of grape 1
Loose, fertile loam rich in organic matter and calcium is needed. Can also be based on local conditions, choose a wide source, low cost, no pests and diseases, pollution-free culture materials. Commonly used materials are humus soil, peat soil, pastoral soil, sand and gravel, bone meal, puffed chicken manure and so on.
2, pot soil preparation and disinfection
The commonly used formulas are: ① 4 parts humus soil, 3 parts garden soil, 3 parts coarse sand and 0.5 part bone meal; ② 7 parts of pastoral soil, 2 parts of coarse sand (or slag), 0 part of expanded chicken manure/kloc-0, and 0.5 part of bone meal. After mixing the pot soil, spray it evenly with 0. 1% formalin solution (500ml per cubic pot soil). Then sealed with plastic film, fumigated for one day and night, peeled off the film, aired for 3-4 days, and then potted for later use.
Grape shaping Usually, there are two kinds of potted grape shaping:
Unipolar shape
Suitable for medium and small potted plants. In the year of planting, erect a bamboo pole or No.8 iron wire in the center of the pot, and the height is about1m. After the new buds germinate, select strong new buds as main vines, pull them onto bamboo poles, and pick the core when they grow to 80-90cm. After that, leave 1-2 leaves to grow except the top secondary buds. In winter, mature branches and vines can be cut off by 50cm. After germination in the second year, leave 3-5 strong new buds on the main vine, and the remaining buds should be erased in time. When pruning in winter, 2-3 buds are reserved for each new shoot as the bearing mother branch for pruning. After germination in the third year, each bearing mother branch leaves 1-2 new shoots, and then it is chopped every year.
