Problems solved by technology

However, it was further found that the fruiting traits of Dongzao in the southern region are poor and unstable. The juvenile trees have lush branches and leaves, strong uprightness, strong vegetative growth, large flower volume, severe flower and fruit drop, and low fruit setting rate, especially Zhanhua Dongzao. Almost no fruit setting , thus greatly affecting the introduction and cultivation of Dongzao, and seriously restricting the development of Dongzao in the south

[0011] 2. Fertilization

[0012] 1. Base fertilizer

[0013] It is very important to apply enough base fertilizer when the seedlings are planted. Plant jujube seedlings in a 1-meter cubic pit or a 1-meter-wide and 1-meter-deep ditch. Apply 100 kg of farmyard manure to each jujube tree, and then fill the original topsoil on the bottom layer The original substratum is backfilled on the surface. In addition, the base fertilizer is mainly concentrated after fruit picking in the previous year, and a 1-meter-deep and 1-meter-wide ditch is opened between the two rows of jujube trees. Generally, the ditch is opened every two years, and each time the ditch is changed from the previous one, this can reduce damage. The root system on the same side is conducive to the robust growth and high yield of jujube trees. The jujube tree base fertilizer is mainly organic fertilizer (such as retting human and animal manure), and each jujube tree uses 30-50kg of organic fertilizer, plus 3-5kg of c...

Abstract

The invention discloses a southern winter-jujube cultivation method, which is to trim the jujube tree to be a high-stem dwarf-crown open-center tree form that is suitable to be cultivated in the South and to control the height of the trunk stem; three strong main branches are reserved; three to four supplementary main branches are reserved on the main branches; the main branches are stretched before the flowering; two to three jujube shoots are reserved as a nutrition branch or a renewing branch for every jujube tree; the branches are topped when the jujube shoot has four to five secondary branches; the secondary branches are topped when the secondary branches are grown into 15 to 25 centimeters; the shedding shoot of the jujube is controlled between 20 to 50 cm; two to three shedding shoots of the jujube are reserved for every spur of jujube; the small shedding shoots of jujube on the trunk stem and on the main branches are removed and the adventitious bud sprouted at the base of thejujube tree is removed; two days before the full flowering stage, the trunk stem is stripped or cut circularly. Adopting the invention, the main branches of the tree crown are opened, ventilated and transmitted and are layered, thereby reducing the insect harm and effectively improving the fruit rate; the winter jujube in the South has high yield; the yield of the four-year-growth apple winter jujube can reach 1887 kilograms per Mu and the yield of the three-year-growth Zhanhua winter jujube can reach 980 kilograms per Mu.

Description

technical field [0001] The invention relates to a high-yield cultivation method for southern jujube. Background technique [0002] The main varieties of Dongzao are Apple Dongzao and Zhanhua Dongzao. Apple Dongzao is native to the Bohai Bay region of Shandong, while Zhanhua Dongzao is native to Zhanhua County near the mouth of the Yellow River in Shandong. Because the flesh of winter jujube is crisp, sweet and delicious, the quality is excellent, and the cultivation efficiency is high, it is deeply loved by the market and local fruit farmers. Since 2002, a large number of Apple Dongzao and Zhanhua Dongzao have been introduced and cultivated in southern Hunan. It has been found that the trees grow well, indicating that they have strong adaptability and can grow in the south. However, it was further found that the fruiting traits of Dongzao in the southern region are poor and unstable. The juvenile trees have lush branches and leaves, strong uprightness, strong vegetative gr...
