Key points of field management of the latest black tiger

Although the black tiger has a bad name, it is a kind of fruit with high nutritional value. Now the market for black tigers has gradually been opened, and more and more people are planting them. However, regardless of the new and old growers, their output is not very ideal. Therefore, in order to increase the output of the black tiger when planting, we should do a good job in the field management of the black tiger. Next, the editor will introduce to you the key points of the field management of the black tiger.

1. Water and fertilizer management

The black tiger has a large demand for water and fertilizer during the whole growth period, so we should do a good job in the management of water and fertilizer in the process of planting. In addition to adequate watering during the flower and fruit stage of black and presbyopia, nutrition is also essential. Topdressing is usually needed about twice a year, respectively before leaf expansion and flowering. For the first time, the farmer made a ditch around the root. Then, for the second time, phosphorus and potassium fertilizer was used to strengthen the growth ability of flowers and fruits. It is best to top fertilize again during the fruit expansion period, and to carry out one-time ploughing and weeding to ensure the quality of the fruit.

2. Set up a fight at the right time

Because the black tiger is a kind of vine, we should build a fight at the right time in the second year after planting. The support material should be stable and strong so that it will not be blown down easily by the wind. According to the planting area and the surrounding environment to determine the form of scaffolding, but no matter what form should be the above downward direction. Avoid being too closed in the orchard and improve permeability. The height of the bracket should be kept at about 2 meters to ensure that the black tiger has plenty of room to climb. After setting up the frame, the main vine of the black tiger is introduced into the bracket, and then let it grow freely.

3. Shaping and pruning

Because the shape of the black tiger tree is relatively large, so shaping and pruning is very important for the growth of the black tiger. The pruning of the black tiger tree should be pruned once every season. Spring pruning should cut off the weak fruiting branches and the old withered branches before the new shoots germinate, and the strong fruiting branches should retain about 10 buds. Then summer pruning was carried out from June to August, and the main pruning objects were basal branches, crossed branches and branches of diseases and insect pests. Branches that are too long and too dense should be removed. Adjust the structure of fruit trees, control the growth of main vines, and prepare for the growth of the second year. In autumn and winter, the basic branches are mainly used to improve the cold resistance of the black tiger tree.

4. Ploughing and weeding

During the growth period of black tiger, the work of ploughing and weeding has a great relationship with the yield and fruit quality of black tiger. Therefore, we should carry out regular weeding work, which can effectively loosen the soil, improve the soil fertility and enhance the nutrient absorption capacity of the black tiger root. And when ploughing, water plates should be made at the base of fruit trees to facilitate drainage and irrigation. It is best to use artificial weeding when weeding, so that no herbicides can be used to avoid damage to the soil and fruit trees and reduce pollution.

The above is a brief introduction to the main points of black tiger field management, the management of black tiger planting is very important. Although the output of the black tiger is low, good management can increase the output. Therefore, we must pay more attention, today's introduction is here, this article is only for reference, I hope to help you!
