Embodiment 1
[0022] Embodiment 1: as Figure 1-2 As shown, an underground continuous irrigation and fertilization method to improve the yield and quality of mangoes, taking the Golden Phoenix mango tree as the research object, burying the micro-moisture pipe of the underground irrigation system in the land planted with 7-year-old mango trees for deficit irrigation and irrigation. Fertilize.
[0023] The concrete steps of described method are as follows:
[0024] Step1. Select 7-year-old mango trees with consistent growth as test materials, with a plant spacing of 5 m and a row spacing of 7 m. The planting direction of the mango trees is north-south; the plant height of the mango trees is 3.0 to 3.2 m, and the stem diameter is 11 to 14 mm;
[0025] Step2. Embedding the micro-running pipes of the underground irrigation system in the land planted with 7-year-old mangoes for continuous underground irrigation, regulated deficit irrigation and fertilization; the period of regulated deficit irri...
Embodiment 2
[0032] Embodiment 2: as Figure 1-2 Shown, a kind of underground continuous irrigation fertigation method that improves mango output and quality, present embodiment is identical with embodiment 1, and difference is:
[0033] Step1, select the 7-year-old mango tree with consistent growth as the test material, the plant spacing is 5.5 m, the row spacing is 7.5 m, and the planting direction of the mango tree is north-south orientation;
[0034] Step2. Embed the micro-running pipe of the underground irrigation system in the land planted with 7-year-old mangoes for continuous underground irrigation, regulated deficit irrigation and fertilization; the period of regulated deficit irrigation is the fruit maturity period, and the irrigation level in the period of regulated deficit is 60% ET C , other periods are 100% ET C ;ET C Water requirement for mango;
[0035] Step3. Fertilize during the growth process of mango, including flowering period, fruit expansion period, and fruit matu...
Embodiment 3
[0036] Embodiment 3: as Figure 1-2 Shown, a kind of underground continuous irrigation fertigation method that improves mango output and quality, present embodiment is identical with embodiment 1, and difference is:
[0037] Step1, select the 7-year-old mango tree with consistent growth as the test material, the plant spacing is 5.3 m, the row spacing is 7.3 m, and the planting direction of the mango tree is north-south orientation;
[0038] Step2. Embed the micro-running pipe of the underground irrigation system in the land planted with 7-year-old mangoes for continuous underground irrigation, regulated deficit irrigation and fertilization; the period of regulated deficit irrigation is the fruit maturity period, and the irrigation level in the period of regulated deficit is 50% ET C , other periods are 100% ET C;ET C Water requirement for mango;
[0039] Step3. Fertilize during the growth process of mango, including flowering period, fruit expansion period, and fruit matur...
