Embodiment 1
[0019] Example 1: Site selection
[0020] Choose sandy loam to clay loam with flat terrain, convenient transportation, and complete drainage and irrigation functions. The thickness of the soil layer is more than 100cm, the pH value is less than 8.5, preferably 6-8.5; the total salt content is less than 0.3%, and the chloride is less than 0.1%.
Embodiment 2
[0021] Example 2: Colonization
[0022] There are two planting periods for winter jujube, one is before and after falling leaves, and the other is before and after germination; the seedlings should be treated before planting, and it is best to soak in clean water for 15 to 20 hours before planting, which is conducive to improving the survival rate; Cut off all the stubble with about 1cm left on the secondary branches, and organize the root system, and then dry it at about 65-80cm above the original ground level; the planting pit is generally 60-90cm square, and it must be adequately fertilized before planting. Apply 20-30kg of farmyard manure to each plant, preferably 25kg, and the farmyard manure is preferably wet chicken manure; and it is evenly mixed with the topsoil. The depth of planting should generally not exceed 3-4cm above the original ground level; after planting, it should be watered in time to facilitate survival, and then cover the tree tray with plastic film, pre...
Embodiment 3
[0024] Example 3: Temperature
[0025] The growth period of winter jujube is sensitive to temperature. When the temperature in spring reaches 16-23°C, flower buds begin to appear and enter the initial flowering stage. When the temperature is around 25°C, it enters the full-blooming stage and the fruit grows rapidly. During the dormant period after falling leaves, Dongzao has strong cold resistance.
