1 Soil management
The scientific management of soil in the process of soft-seed pomegranate cultivation has a very important influence on the yield quality of pomegranate. It is necessary to pay attention to the change of soil fertility throughout the production process. Before planting the pomegranate, the soil in the orchard should be turned deep. In order to enhance the soil fertility, some green manure such as green manure can be planted on the land to grow into the summer heat. The green manure is cut down and filled in the canopy and buried to improve the soil fertility.
2 Fertilizer management
2.1 scientific topdressing
In the planting of seedlings, it is necessary to carry out expansion and topdressing. Control the amount of nitrogen fertilizer applied during topdressing to increase the ability of the tree to resist cold.
2.2 Foliar spray fertilizer
Foliar spray fertilizer makes the amount less effective and high energy can quickly take effect. In the early stage of pomegranate growth, it should be combined with the prevention and control of pests and diseases, and the fertilizer can be selected from 0.3% to 0.5% urea and 0.2% to 0.3% potassium dihydrogen phosphate solution to help thicken and enlarge the leaves. And increase photosynthesis to promote fruit yield and quality.
3 Water management
According to the different growth stages of soft pomegranate and different climatic conditions, it is reasonable to water the pomegranate trees before germination, before flowering, before flowering and before the rapid growth period of fruit, and it is necessary to Watering and frequency are different in different regions and different climatic environments. To ensure that there is sufficient moisture in each growth stage. When watering in the dry period, be careful not to blindly increase the number of watering and watering, in order to prevent excessive expansion of the pomegranate fruit due to excessive water and a large number of cracked fruits. In the summer, you should be careful to remove moisture and prevent phlegm to prevent the pomegranate tree from rotting.
4 Tree management
Pomegranate has the physiological characteristics of germination and strong light, so the branches in the crown should be trimmed into a dense and dense distribution structure to facilitate good ventilation and light transmission. Need to pay attention to the plastic trimming of the branches, in the summer also need to pick the heart, but also pay attention to the new sprout to wipe out to prevent the consumption of nutrients. Helps increase production.
4.1 shaping
For the straight pomegranate main branch, the main branches can be pulled in different directions by pulling and pulling. The opening angle of the main branch is usually 40-50, which is beneficial to the development of the crown and increase the light to extract the fruit. Production.
4.2 smear
The branches sprouted on the base of the trunk and the back of the main branch must be erased in the first time to prevent the consumption of nutrients. If the inner space of the crown is relatively large, the appropriate part can be selected on the back of the main branch. The appropriate amount of germination strips, but must be topped to cultivate into the inner sputum result branch group.
4.3 trimming
Soft-seed pomegranate has physiological characteristics such as rapid growth of the tree, early result, fast update, and large number of side branches, which can achieve premature birth and high yield. The pruning work should be based on reducing the number of side branches. Generally, there are 3 to 4 main branches, and 3 to 4 sub-branches appear on each main branch. The whole plant's branches and trees must be well repaired. The 4th year is an important stage of pruning. At this time, the density of the pomegranate garden cuts off many auxiliary branches, and the angle between the branches is adjusted to enhance the ventilation effect to ensure that the nutrient concentrates on the trunk to ensure the trunk grows vigorously. When the new shoots are growing in mid-August, the growth points should be removed and removed to control overgrowth to improve the ability of the plants to keep warm.
4.4 Flower Management
The self-pollination rate of pomegranate is extremely low, and it is easy to fall and drop fruit. Therefore, when the flower buds begin to appear at the beginning of April, the strips should be stripped at the base of the resulting backbone, and the wounds should be wrapped after the end; the growing trees or branches need to be cut 2 to 3 times, between each road. The distance is above 4cm. In order to increase the fruit setting rate, powdering can be carried out by artificial pollination or release of bees. After the results, pests, double fruits, small fruits, and late fruits will be removed in time to ensure that the pomegranate maturity is consistent.
