Now there are many varieties of winter jujube, and each variety has its own advantages and strong adaptability to the environment. However, planting different varieties in different regions will also have certain differences in yield and quality. Therefore, we generally choose high-quality varieties for planting according to the planting environment, climatic conditions and market conditions of the location.

2. Soil preparation and fertilization

Winter jujube is suitable for planting in flat terrain, sufficient sunshine, sufficient soil fertility and organic matter content, close to water sources, water quality is not polluted, drainage and irrigation system is perfect, and soil pollution is not affected. Soil preparation can usually be carried out by full cultivation or hole cultivation. It should be noted that deep ploughing must be carried out when soil preparation is carried out. Machine can be used to prepare soil, so that impurities in the field will be cleaned thoroughly. Then dig the hole, pour enough farm manure into the hole, cover it with a layer of fine soil about five centimeters, and finally wait for planting.

Because the branches and leaves of winter jujube trees grow faster, it is necessary to plan the planting density when planting. Generally, the specific dense planting is carried out according to the growth characteristics of winter jujube trees and the fertility of the soil planted. Usually, we adopt the distance of three meters to four meters between rows and two meters to three meters between plants. According to this spacing, about 55 to 110 winter jujube trees can be planted per mu.

Nitrogen fertilizer is generally only used to promote the growth of branches and leaves at the stage of young trees and in spring every year. At other times, organic fertilizer is mainly used, and appropriate amounts of phosphorus fertilizer and potassium fertilizer are also needed. Some foliar fertilizer can be sprayed at flowering and expiration. Finally, attention should be paid to pruning and shaping branches and leaves of fruit trees from time to time to ensure the passage of fields and the yield and quality of winter jujube.
