Planting Management of Dormancy Period in Dongzao

In November, the winter jujube tree enters a dormant period, which is a favorable period for the planting of winter jujube. The main tasks of this month include the application of base fertilizer, tree protection and new garden construction.

One, base fertilizer

Shiji fertilizer at this time, high ground temperature, high soil moisture, fertilizer decomposition, is conducive to root absorption. The method of furrowing can be adopted, and 25-50 kilograms of soil-fertilizer can be applied to each tree. When the soil-fertilizer is applied, 2 kg of superphosphate can be added to each tree.

Second, white

10 parts of quicklime, 1 part of salt, 50 parts of water and 5 parts of lime sulfur can be mixed and applied to the trunk.

Third, build a garden

1, garden choice. The jujube tree is a perennial fruit tree with shallow roots and high light intensity. The result is early, long life, no strict requirements on the soil, drought tolerance, waterlogging resistance, and salt and alkali resistance. It can grow in soil with a pH of 5.5-8.5. However, for the newly-built garden, the growth and development needs of the tree should be met as much as possible. Therefore, the plot should be selected as a plot with flat terrain, sufficient light, fertile soil, good drainage and irrigation, and no pollution. 2, planting time. After planting the seedlings in autumn, the soil is suitable for freezing. 3, planting density. Commonly used in the production of a spacing of 23 meters, 34 meters, 37 meters, according to the characteristics of winter hi light, but also the rational use of the principle of land, 23 meters, 34 meters of these two kinds of ideal density.

IV. Planting methods

Generally single row planting, multi-use rectangular, spacing is greater than the distance between the rows, the line to the north and south is appropriate.

V. Planting techniques

1, seedlings selection and processing. Jiandongzao dense planting gardens should be selected to have a height of 1.2 meters or more, a dry diameter of 1 cm or more, a complete root system, pure breeds, good healing of grafted parts, and strong disease-free seedlings. Seedlings planted with the best seedlings planted, long-distance transport from the field of seedlings soaked with water for 10-20 hours before planting the wound roots for renovation. In order to improve the survival rate, rooting powder can be used for spraying. Specific practice: Dissolve rooting powder No. 3 with a small amount of alcohol, and then spray 10-25 kg per g of water, then cover with wet grass mat for 2 hours before planting. 2, planting points. Dig a planting hole with a width and depth of 0.8-1m. The topsoil shall be separated from the new soil. Each planting point shall be filled with 25kg of Shinongjiafu and mix with the topsoil and then fill in the hole. With the fill, with the raising of the seedlings, with practicality. The depth of planting is such that the rhizome position of the seedlings is slightly higher than the ground. After irrigation and sinking, the rhizomes are flat with the ground plane.

Sixth, post-plant management

The seedlings planted in the fall must be protected against cold in order to ensure their safe wintering. Specific practices: (1), white, grass tied. Immediately after planting, apply white and tie the grass. Whitening agent configuration method: 18 kg of water + 2.5 kg of salt + 0.1 kg of vegetable oil + 0.05 kg of starch + 0.75 kg of sulfur powder. (2) Protecting the earth against cold. In the base of seedlings, a 30 cm soil mound is kept cold, and after the spring thaw in the spring, it is divided into 2-3 times.
