Embodiment 1
[0017] Choose to grow kiwi fruit in the Maiji Mountains, Tianshui City, Gansu Province.
[0018] 1) Site selection: The planting site is selected to be 10km away from the pollution source, and the hillside cultivation is selected on a semi-shady slope. The local sunshine duration is generally 800h, the annual rainfall in the selected area is 1000mm, and the air humidity can be maintained at 70% for a long time.
[0019] 2) Soil quality improvement: Apply 25kg of fine furnace ash, 45kg of decomposed livestock manure, 15kg of peat, 15kg of mushroom residue, 100g of urea, 100g of soil water-retaining agent, and 40g of resin-coated slow-release fertilizer according to fertilization per mu per square meter. The plowing depth is 25-30cm. After plowing, make a bed. At the same time, the soil is deeply disinfected with 500 times of 50% phoxim EC or 500 times of 40% isofenphos-methyl.
[0020] 3) Selection and planting of seedlings: select seedlings or virus-free seedlings that grow ro...
Embodiment 2
[0027] The present embodiment is the same as Example 1, except that the selection and planting of seedlings in the implementation step 3) are: selection of robust growth, seedlings or virus-free seedlings with certain resistance to diseases and insect pests, plant spacing according to 2m, row spacing 3m, strain sex ratio= 10:1 matching, according to the condition of the root system of the plant, dig a hole for planting, pour a sufficient amount of water after planting, and make a planting plate with a direct diameter of 0.8m around the plant.
Embodiment 3
[0029] Utilize xylene extraction colorimetric assay method, carry out the mensuration of the content of Vc to kiwi fruit, take the ripe kiwi fruit in embodiment 1, embodiment 2 and traditional planting method at random, and take traditional planting method as contrast (CK) .
