Embodiment 1

[0037] Take the 150-mu sloping field of Xiangcheng Town, Xiangyun County, Dali Prefecture, Yunnan Province as an example. The altitude is 1950-1980m, the annual average temperature is 15.4°C, the annual precipitation is 728.6mm, and the number of sunshine hours 2648.6h, it belongs to the northern subtropical climate, without severe cold in winter and hot summer in summer. The soil is mainly red soil, the slope of the garden does not exceed 6 degrees, the soil pH value is 4.5, and the soil organic matter content is not less than 12%. The specific cultivation steps are as follows:

[0038] A. Field arrangement: Deep plow the field selected above with a depth of 25cm one year before planting.

[0039] B. Planting of fruit seedlings: Select 2-year-old sterile Jietu tissue-cultured blueberry seedlings with a seedling height of 55 cm and 2-year-old sterile Sharp blue tissue-cultured blueberry seedlings with a seedling height of 45 cm, and the selected blueberry seedlings have mor...

Embodiment 2

[0044] Taking 2-year-old Baldwin (rabbit-eye species) cutting seedlings cultivated on 350 mu of sloping land in Baoxiu Town, Shiping County, Honghe Prefecture, Yunnan Province as an example, it is located at 23°31′ to 23°50′ north latitude and 102°08′ to 102°08′ east longitude. 102°27′, the altitude of the garden is 1280~1320m, the annual average temperature is 18℃, the annual precipitation is 775~1148mm, and the sunshine hours are 2648.6h, which belongs to the typical mid-subtropical climate. The slope of the garden is 6-8 degrees, the soil pH value is 6.5, and the soil organic matter content is greater than 16%. The specific cultivation steps are as follows:

[0045] A. Field finishing: Deep plow the field selected above with a depth of 20cm one year before planting, and apply sulfur powder and acid peat while deep plowing to adjust the pH value of the field to 4.8.

[0046] B, planting of fruit seedlings: select the 2-year-old aseptic Baldwin cutting blueberry seedlings ...

Embodiment 3

[0051] Take the 200-mu slope land cultivation of 3-year-old blue line (Northern High Species) grafted seedlings in Liming Lisu Township, Yulong Autonomous County, Lijiang City, Yunnan Province as an example. Between °46′, the altitude of the garden is 2530-2600m, the annual average temperature is 9.6°C, the annual precipitation is about 800.6mm, and the annual frost-free period is 200 days. It belongs to the low-latitude plateau South Asian monsoon semi-mountain climate. The slope of the garden is 8-10 degrees, the soil pH value is 6.0, and the soil organic matter content is about 7%. The specific cultivation steps are as follows:

[0052] A. Field finishing: Deep plow the field selected above at a depth of 25cm one year before planting, and apply sulfur powder and ferrous sulfate powder while deep plowing to adjust the pH value of the field to 5.0.

[0053] B. Planting of fruit seedlings: Select 3-year-old Blue Line (North High Species) with a seedling height of 70 cm or m...

Abstract

The invention discloses a method for cultivating organic blueberries in low-latitude and high-altitude areas. The method comprises the steps as follows: selecting fields with the slope gradient not higher than 10 degrees, the soil PH value being 4.0-6.0 and the organic matter content being not lower than 5%, and carrying out field soil preparation with the deep tillage depth being 20-25 cm in the year before field planting; selecting blueberry seedlings to perform field planting in winter or in rainy seasons of the next year, then covering a moist soil surface with a mulching material and performing filed planting on seedlings which are sufficiently watered; performing fruit tree pruning twice including pruning after fruit picking, and pruning and disbranching in winter; adopting drop irrigation or irrigation to maintain the maximum water-holding capacity of the soil to be 60-70%, and applying organic fertilizer in twice every year, wherein applying organic fertilizer after blueberry harvest and before spring-growth on the moist soil surface, and applying fertilizer heavily while ditching to realize water and fertilizer management; trapping the adults and larva of scarabs by adopting light and / or trapping and killing by using willow leaves impregnated with pesticide and performing deep ploughing to enable the larva of scarabs to be exposed to the sun; trapping and killing drosophila melanogasters with sweet lure or yellow sticky boards. The method for cultivating organic blueberries in low-latitude and high-altitude areas has the characteristics that the management is simple and convenient, damage caused by diseases is less, good harvest and high quality of the blueberries are achieved, and the blueberries obtained by adopting the method are purely natural and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for cultivating organic blueberries in low-latitude and high-altitude regions with simple management, few diseases, high-yield and high-quality fruits, and natural pollution-free. Background technique [0002] Blueberry (Blueberry) belongs to Rhododendronaceae (Ericaceae) Vaccinium (Vaccinium) berry evergreen shrub, the scientific name is bilberry, the fruit is mostly blue-purple, soft and juicy, moderately sweet and sour, pure flavor, special aroma, rich Contains vitamin C and has high food value. It has been proved by modern medical research and animal experiments that the unique antioxidant substances such as blueberry anthocyanins in the berries have unique effects such as preventing brain aging, enhancing heart function, preventing visual fatigue, and preventing cancer. Therefore, the Food and Agriculture Organization of the United Natio...
