Problems solved by technology

However, this method uses water and fertilizer on the soil surface or sprays it on the crops. The disadvantages are as follows: 1. In areas with dry climate, the surface evaporation is large, and the water disperses quickly, resulting in high fertilizer concentration and the risk of root burning; 2. Spraying on the surface of crops requires a power system, which wastes a certain amount of energy; 3. In a mango orchard with a

Example Embodiment

[0038] Example 1

[0039] This embodiment provides a water-fertilizer integrated fertilization method for mangoes, which is to dissolve water-soluble fertilizers in water and infiltrate them into the soil of the root zone, including fertilizer for infiltration irrigation during flower bud differentiation of mango, fertilizer for infiltration irrigation during mango flowering, and young fruit Fertilizer for infiltration irrigation during the increase period and fertilizer for infiltration irrigation after mango picking; the specific methods are as follows:

[0040] 1. One month before flowering is the period of mango flower bud differentiation. Fertilizer for infiltration irrigation is used once, including high-nitrogen and high-phosphorus fertilizer 20Kg / mu, and water-soluble organic carbon fertilizer 40kg / mu. Foliar fertilizer 300ml / mu of boron fertilizer and 250ml / mu of zinc fertilizer are sprayed on the leaves.

[0041] 2. When mangoes bloom in large quantities, use fertilizer tw...

Example Embodiment

[0044] Example 2

[0045] Example 2 is a variation of Example 1. The changes are indicated in:

[0046] 1. Mango flower bud differentiation period: high nitrogen and high phosphorus fertilizer 10kg / mu, water-soluble organic carbon fertilizer 20kg / mu. Foliar fertilizer 200ml / mu of boron fertilizer and 200ml / mu of zinc fertilizer are sprayed on the leaves.

[0047] 2. Mango flowering period: high calcium and high magnesium fertilizer 20kg / mu, bacterial solution 10L / mu. Spray 200ml calcium fertilizer once.

[0048] 3. During the growth period of young fruit: use fertilizer once for infiltration irrigation, including high-potassium fertilizer 10kg / mu and water-soluble organic carbon fertilizer 20kg / mu.

[0049] 4. Fertilizer after mango picking: high nitrogen and high phosphorus fertilizer 10k / mu g. Organic fertilizer 40kg / mu, soil conditioner 20kg / mu, dig a hole and bury it in a tree tray.

Example Embodiment

[0050] Example 3

[0051] Example 3 is a variation of Example 1. The changes are indicated in:

[0052] 1. Mango flower bud differentiation period: high nitrogen and high phosphorus fertilizer 50Kg / mu, water-soluble organic carbon fertilizer 60k / mu g. Foliar fertilizer 500ml / mu of boron fertilizer and 500ml / mu of zinc fertilizer are sprayed on the leaves.

[0053] 2. Mango flowering period: 60kg / mu of high calcium and high magnesium fertilizer, 50L / mu of bacterial solution. Spray 500ml calcium fertilizer once.

[0054] 3. During the period of young fruit enlargement: use fertilizer once for infiltration irrigation, including high-potassium fertilizer 50kg / mu and water-soluble organic carbon fertilizer 60kg / mu.

[0055] 4. Fertilizer after mango picking: high nitrogen and high phosphorus fertilizer 50kg / mu. Organic fertilizer 40kg / mu, soil conditioner 60kg / mu, dig a hole and bury it in a tree tray.

Abstract

The invention discloses a water and fertilizer integrated fertilizer applying method for mangoes, which belongs to the technical field of agricultural irrigation and fertilizer application. The water and fertilizer integrated fertilizer applying method comprises the following steps of dissolving a water soluble fertilizer in water, and performing infiltration irrigation to soil at root zones, wherein the infiltration irrigation specifically comprises infiltration irrigation fertilizer application for mangoes at a flower bud differentiation period, infiltration irrigation fertilizer application for mangoes at a flowering period, infiltration irrigation fertilizer application for mangoes at a young fruit enlarging period, and infiltration irrigation fertilizer application for mangoes after being picked. Compared with a conventional fertilizer applying method, the water and fertilizer integrated fertilizer applying method disclosed by the invention has the advantages that the amount of the fertilizer is saved by 50% or above, the evaporation amount of water is notably reduced, and water is saved by 80%; the problem of pressure difference caused by a slope is solved, flow quantities of the water and the fertilizer on slopes and below the slopes are uniform, the growth vigours of tree bodies on the slopes and below the slopes are the same, and the yield is notably increased by 30% or above. An infiltration irrigation pipeline used for the method is buried underground, and farming operations of field weeding and insecticide spraying are not influenced.

Description

technical field [0001] The invention relates to a mango water and fertilizer integrated fertilization method, which belongs to the technical field of agricultural irrigation and fertilization. Background technique [0002] The traditional mango fertilization method is to dig a pit under the mango tree before the mango blooms, and bury the whole year's fertilizer in the pit at one time. However, this approach is extremely unreasonable for the following reasons: [0003] The growth and development of mango requires 16 kinds of essential nutrients, and it absorbs a large amount of nitrogen, phosphorus, potassium, calcium and magnesium from the soil. Every 1000 kg of fresh fruit needs 1.735 kg of nitrogen (N), 0.231 kg of phosphorus (P2O5), 1.974 kg of potassium (K2O), 0.252 kg of calcium (CaO), and 0.228 kg of magnesium (MgO). In other words, its absorption ratio is 1:0.13:1.14:0.15:0.13. In different growth stages of mango trees, the absorption of various nutrients by leave...
