How many jin of red grape per mu? How to fertilize and plant?

Red grape, also known as Red Earth, is listed as the first of the four major fruits in the world. It is planted in Weinan, Xinjiang, Yunnan, Gansu and other places in China. So how many jin of red grapes per mu? How to fertilize and plant? Next, let's learn about:

1. How many jin of red grapes per mu?

The yield of Hongti grape per mu is mainly determined by the planting place, soil, climate and other factors. Generally speaking, the red grape vine begins to bear fruit in the second year, and the annual yield will increase accordingly. By the fifth year, the yield of Hongti grapes per mu will reach about 2000 kilograms.

2. Fertilization technology of red grape.

1. Apply more organic fertilizer. It is required that young trees should apply base fertilizer from September to October every year, organic fertilizer should be applied more than 2000kg per mu, and mature trees should apply more than 5000kg.

two。 Apply more potash fertilizer. Every year, young trees should apply 40kg per mu of potassium sulfate, and mature trees should apply 100kg.

3. Apply more calcium fertilizer appropriately. It is required that calcium or amino acid calcium can be sprayed 2-3 times in the middle and later stage of fruit growth.

4. Attach importance to micro-fertilizer. Although there is little demand for trace elements such as iron, boron, zinc and aminooligosaccharins, they directly affect the improvement of yield and quality. Microfertilizer should be sprayed for 4 times during the growing period. In addition, fertilizer should be applied according to the needs of growth. Nitrogen, zinc and boron should be applied mainly from bud to flowering stage, supplemented by phosphorus, calcium and magnesium, phosphorus and potassium should be applied mainly and nitrogen should be supplemented from young fruit to color conversion stage, potassium, calcium and phosphorus should be applied mainly and nitrogen should be used as auxiliary during the period from berry expansion to maturity, and basic fertilizer should be applied mainly with sheep manure, chicken manure and oil residue from September to October after fruit harvesting, supplemented by potassium sulfate three-element chemical fertilizer.

3. Planting techniques of red grape

1. Reasonable construction of the garden. People can choose those places where there are no pollution sources, good environment, sufficient sunshine, convenient watering, high terrain and no large shelter as the planting base of red grape.

two。 Choose a variety. The red grape seedlings that people choose should be virus-free, and the purity of the varieties should be more than 98%. Moreover, the roots and seedlings should be robust and the roots should be evenly distributed.

3. Seedlings are planted. In the north, planting in autumn is much better than in spring, but in order to ensure the safety of newly planted seedlings and to facilitate irrigation, people had better choose to plant in spring. Before planting, people also need to dig a planting ditch with tools, add some mixture to the field, and then irrigate it properly. In addition, people need to prune and disinfect each seedling before planting. Finally, put some fertilizer in the planting line, insert red grape seedlings and fill the soil.

4. Fertilizer and water management. When applying fertilizer to red grape seedlings, people should follow the principle of moderate fertilizer and reasonable application of nitrogen. in addition, it is necessary to appropriately increase the proportion of phosphorus and potassium. After each fertilization, people also need to water the seedlings, once.

5. Plastic surgery and trimming. When the main vine of red grape grows to a certain stage, people need pruning. When pruning, the main vine must be kept at about 1.5 meters, the branches on both sides of the front section should be uniform, a fruiting branch should be reserved 20 centimeters away from each branch, and then a vegetative branch should be arranged to come in, so that the fruiting branch and vegetative branch can be converted every year.

four。 Efficacy and function of red grape

1. Anti-anemia: red grape contains vitamin B12, which has the effect of anti-malignant anemia, which can effectively resist the symptoms of anemia. It is rich in glucose and is easily absorbed by the human body. it also helps to resist the symptoms of anemia.

two。 Enhance immunity: red grape is rich in vitamins and amino acids, which can excite brain nerves and eliminate fatigue. At the same time, containing polyhydroxyphenols can kill bacteria and viruses in the body, thereby enhancing the body's immunity.

3. Detumescence and calming the fetus: for pregnant women, pregnancy is not only a very important stage, but also a very difficult stage. Pregnant women often have symptoms such as nausea, vomiting, edema and so on. The nutrients in red grapes have the effect of diuresis, detumescence and calming the fetus.

4. Anti-aging: red grape is rich in anthocyanins, which has strong antioxidant activity, which helps to eliminate free radicals and prevent protein and nucleic acid from being destroyed by free radicals, thus delaying aging and prolonging life.

Red grape, with unique flavor, high quality and reasonable price, can bring wonderful enjoyment to people's taste buds. For investors, red grape planting, high yield per mu, broad prospects, is a very good investment project.
