Problems solved by technology

[0004] The longest cultivation time of winter jujube in Zhanhua area has reached more than 20 years. However, with the extension of winter jujube cultivation time, excessive pursuit of yield and unreasonable soil fertilization management measures have led to obvious soil fertility degradation in many jujube orchards. As a result, the yield and quality of winter jujubes have declined significantly, and the economic benefits per unit area of ​​different jujube orchards can vary by 3-8 times.
Among them, the extensive fertilization method is a prominent problem in the soil management of jujube orchards. Without nutritional diagnosis of jujube trees, the determination of the type and quantity of fertilization is lack of pertinence. technical problems in management

Embodiment 1

[0045] Example 1: Fengjia Town, Zhanhua District

[0046] Select the typical jujube orchard with 13 years of tree age in Fengjia Town, Zhanhua District, apply the soil management method of the present invention to carry out the soil management of the winter jujube orchard, the specific management techniques and the impact on the quality of the winter jujube fruit are as follows:

[0047] 1. Deep soil plowing and base fertilizer application in autumn

[0048] In Fengjia Town, the core production area of ​​Zhanhua Dongzao, a 13-year-old jujube orchard was selected, and the distance between the rows of fruit trees was 60 cm. The width of the ditch was 50 cm, and the depth was 50 cm. The left side of the ditch, while the bottom 25-50cm soil is placed on the right side of the ditch. After the fertilizer is evenly mixed with 0-25cm soil, backfill to the bottom of the ditch first, and then backfill the lower 25-50cm soil finally. Autumn basal fertilizer fertilizer type and applicat...

Embodiment 2

[0057] Example 2: Xiawa Town, Zhanhua County

[0058] In Xiawa Town, Zhanhua District, select a typical jujube garden with a tree age of 16 years, and apply the soil management method of the present invention to carry out the soil management of the winter jujube garden. The specific management techniques and the impact on the quality of the winter jujube fruit are as follows:

[0059] 1. Deep soil plowing and base fertilizer application in autumn

[0060] Choose a jujube orchard with a tree age of about 16 years, and choose a ditch between rows 70cm away from the fruit trees to dig deep. The width of the ditch is 55cm, and the depth is 40cm. Soil was placed on the right side of the ditch. After the fertilizer is evenly mixed with the top layer of 0-20cm soil, it is backfilled to the bottom of the ditch first, and then the lower layer of 20-40cm soil is finally backfilled. The fertilizer type and application rate of autumn basal fertilizer are: 2.0 tons / mu of finished organic...

Abstract

The invention discloses a soil management method for improving the fruit quality of winter jujubes. According to the method, a topdressing method in the fruit developing period is guided by making a nutrition diagnosis standard for the young fruit period of winter jujubes, and the fruit quality of winter jujubes can be improved by autumn deep-digging and fertilizing, replacement of upper and lower layers of soil, sod cultivation in an orchard, yield control and other comprehensive soil management methods. The soil management method can be used for remarkably improving the fruit quality of winter jujubes, and thus the economic benefits can be greatly promoted.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and particularly relates to a soil management method for improving the fruit quality of Ziziphus jujuba cv.
