Planting techniques of currant

Currant is a plant of gooseberry family, which is mainly distributed in northern China, and its main mature period is in summer every year. Originally a favorite berry for Europeans, it was later found by Chinese that it was also very popular after it was introduced into China. Currant can be used to make jam, wine, beverage and other products, which has high economic value. So how to grow currants? The following editor brings you the planting technology of currants, let's have a look!

1. Site selection and planting

Currants prefer acidic soil and have higher yield on the soil with rich soil, rich organic matter and loose and deep soil. In addition, we should select the land with low elevation and ventilation to the sun, and do a good job of soil preparation after land selection, deep ploughing, disinfection and fertilization. Then timely planting in spring, because both temperature and water in spring are very suitable for gooseberry seed germination and seedling emergence to improve the survival rate of seedlings. Before planting, the planting density should be controlled according to the planting quantity and the planting holes should be dug. Currant plants are relatively luxuriant, if the planting is too dense, the branches may extend to the nearby plants, affecting the growth.

2. Fertilizer and water management

After successful planting, we should do a good job in fertilizer and water management. first of all, we should apply sufficient base fertilizer before planting, which is mainly based on rotten farm manure, which can be carried out together with soil preparation to ensure that fertilizer and soil are fully mixed. After application, press the soil tightly and pour enough water. Then, according to the growth of the plant, topdressing should be carried out at least twice a year, the first time in the seed germination stage of urea available nitrogen fertilizer, and then after falling flowers and then another compound fertilizer. To promote the growth of currant, pay attention to the position when applying fertilizer, do not touch the plant directly, and avoid burning roots. The water content of the soil should not be less than 70%, but it should not be too much, and attention should be paid to timely drainage when there is stagnant water.

3. Shaping and pruning

Currant plants are very luxuriant and there are many branches, so shaping and pruning is very important. If the pruning work is not done well, the branches of the plant will be disorganized, which will not only affect the light absorption, reduce the flowering and fruiting rate, but also seriously hinder the fruit harvest in the later stage. The pruning of currant, like topdressing, should be carried out at least twice a year. For the first time in the budding period, the basal branches of currant plants are controlled at about 18, divided into four years, leaving 4-5 per year, forming an annual basal plant cluster. At the same time, sagging, overlong and dense branches and branches of diseases and insect pests are cut off to improve orchard permeability and promote flowering and fruiting.

4. Pest control

The common diseases and insect pests of currant are powdery mildew, wing moth and so on, no matter what diseases and insect pests do great harm to the growth of currant. Powdery mildew will harm plant leaves, make them black and withered, and leaf damage will affect plant photosynthesis, resulting in serious deficiency of nutrition accumulation, reduction of yield and poor fruit quality. The winged moth can harm the branches of the plant, causing the branches to wither and fall. We must do a good job in the prevention and control of diseases and insect pests, strengthen orchard management, pay attention to planting density, enhance field permeability, cut off damaged branches and leaves in time, and disinfect orchards regularly to avoid unnecessary economic losses.

The above is a brief introduction to the planting technology of currant, the yield of currant is very high, but we need to do a good job in planting management. Many planting failures are caused by poor management, so I hope everyone will master the management skills and do the most basic management work before planting. And understand the growth habits of currant, properly adjust the growth environment of currant, ensure the yield and quality of currant, and improve the planting efficiency.
