The management technology of snow jujube should not be too rough.

Snow jujube is favored by people for its excellent quality, and it has a large development area in recent years. However, there are some problems in production, such as small fruit, difference in size, poor coloring, light flavor and so on. Take the following measures, can effectively improve the situation.

The main results are as follows: 1. Organic fertilizer is applied in late September every year (before and after fruit harvest), and 100 kg of farm manure and 2 kg of calcium magnesium phosphate fertilizer are applied to fruiting trees.

2. The tree plate is covered with grass in the middle of September (fruit expansion period). The thickness of the grass cover is 15ml / 20cm. After that, the new grass is kept 20cm thick and pressed to prevent it from being blown away by the wind and fire.

3. After controlling the load of snow jujube trees to achieve early high yield, it is easy to appear the phenomena of insufficient nutrition and small fruit caused by large flowering. In addition to strengthening the management of soil, fertilizer and water, the appropriate amount of fruit should be determined according to the load capacity of the tree, so as to maintain high yield and high quality year after year.

4. the reflective film was laid on the ground in the middle of September (before fruit coloring), and the reflective film was laid under the crown to enhance the light intensity of the middle and lower part of the crown, promote fruit coloring and increase sugar content. The method is to lay a reflective film with a width of 1 meter on each side 0.5 meters away from the trunk under each row of canopy. Press the edges with earth or bricks.

5. Pruning and close planting of snow jujube in summer and autumn must be strengthened in summer and autumn to prevent branches from flourishing and growing, resulting in interplant grafting, poor ventilation, lack of light, poor coloring and light. Main measures: cut the prosperous long jujube and the secondary branches at flowering stage to improve the fruit setting rate. Timely erase the useless branches and buds sprouting on the trunk and remove the dense jujube inside the crown. The backbone branches and fruiting branches whose growth orientation and angle are not ideal are adjusted by pulling branches.

6. The best harvest time of snow jujube is in the middle of October. The snow jujube harvested at this time has many red fruits and high sugar content.
