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...

Abstract

The invention relates to an underground continuous irrigation and fertilization method for increasing the yield of mangos and improving the quality of the mangos and belongs to the technical field ofmango cultivation. According to the method, golden phoenix mango trees are adopted as research objects, micro-wetting pipes of an underground irrigation system are buried in the land where the seven-year-old mango trees are planted to carry out underground continuous irrigation in combination with regulated deficit irrigation in a maturity stage; fertilization is carried out at different development stages of mango fruits (including a flowering stage, a fruit expansion stage and a fruit maturity stage). The method is simple in operation, capable of maintaining the wettability of soil in mangoroot areas and favorable for increasing the yield of the mangos and improving the quality of the mangos, the income of local fruit farmers can be augmented, and the local economy is developed.

Description

technical field [0001] The invention relates to an underground continuous irrigation and fertilization method for improving the yield and quality of mango, and belongs to the technical field of mango cultivation. Background technique [0002] Mango is one of the top five tropical fruits in the world and is known as the "King of Tropical Fruits". The dry and hot valleys in Yunnan have sufficient light and heat, and the temperature is high in winter, which is suitable for the growth of mangoes. However, due to the low and uneven distribution of precipitation in dry and hot areas, large evaporation, imbalance of water and heat balance, and extensive water and fertilizer management, mango production cannot be guaranteed. Therefore, a reasonable water and fertilizer management model is an inevitable choice for mango to save water and increase production. [0003] Subsurface irrigation directly transports water and fertilizer to the root system of crops, so it has the characteris...
