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.

Abstract

The invention relates to a winter jujube culture method, which comprises the following steps of S1, land selection: sandy loam or clay loam with irrigation and drainage convenience and thick soil layer is selected; S2, field planting: the tree seedling is soaked in clear water for 15 to 20 hours before the field planting; farm manure is applied before planting, then, the field planting is carried out, and the field planting depth does not exceed 3 to 4cm of the original ground plane; the sufficient water is watered in time after the field planting, and then, the tree disc is covered by a plastic film; S3, soil management: grass coverage and grass growth are carried out in a winter jujube orchard; S4, fertilizer application: fertilizers are applied for one to three times in each year, and the applied fertilizers include farm manure, urea, phosphate fertilizers and potash fertilizers; S5, disease and insect pest prevention and control. Winter jujubes obtained by the method are natural and pollution-free, the culture method is simple, the cost investment is low, and the yield of the winter jujubes is higher.

Description

technical field [0001] The invention relates to the cultivation of a kind of fruit in the field of agriculture, in particular to a technology for planting and cultivating winter jujube. Background technique [0002] Dongzao belongs to the family Rhamnaceae, and it is a late-maturing and fresh-eating fine variety of the thornless jujube species. It is resistant to drought and flood, salt and alkali, and has strong adaptability to soil. However, it can achieve higher economic yields when grown under favorable conditions. At present, there is no systematic technology for planting winter jujube in my country to cultivate natural pollution-free, low-cost and high-yielding winter jujube. Contents of the invention [0003] The object of the present invention is to provide a method for cultivating winter jujube. The obtained winter jujube is natural and pollution-free, the cultivation method is simple, the cost investment is low, and the yield of winter jujube is relatively high...
