Embodiment 1

[0026] A method for integrated fertilization of macadamia nuts with water and fertilizer, comprising the following steps:

[0027] (1) Fertilization in the early stage of heading: In mid-February, when the branches of macadamia nut Guire No. 1 start to head, the fertilizer solution is applied once with the integrated water and fertilizer system. First, the control system of the integrated water and fertilizer system is started, and blank irrigation is performed with clean water. The irrigation amount is 7.1kg / plant, and then converted to fertilizer solution irrigation. The fertilizer solution for irrigation is obtained by completely dissolving 4 parts of urea, 1.65 parts of potassium dihydrogen phosphate, and 0.90 parts of potassium chloride in water. The concentration is 2g / L. 110kg / plant, water and fertilizer are applied by sprinkler irrigation, and the irrigation flow rate is 19L / h;

[0028] (2) Fertilization during the blooming period: In the middle and late March, when 80...

Embodiment 2

[0034] A method for integrated fertilization of macadamia nuts with water and fertilizer, comprising the following steps:

[0035](1) Fertilization in the early stage of heading: when macadamia nut A16 begins to have branches heading in late February, apply fertilizer solution once with the integrated water and fertilizer system, first start the control system of the integrated water and fertilizer system, and perform blank irrigation with clean water. 7kg / plant, then switch to fertilizer solution irrigation, the fertilizer solution for irrigation is obtained by completely dissolving 4.11 parts of urea, 1.69 parts of potassium dihydrogen phosphate, and 0.75 parts of potassium sulfate in water, the concentration is 2g / L, and the dosage is 103kg / plant. Water and fertilizer are applied in the form of sprinkler irrigation, and the flow rate of irrigation is 20L / h;

[0036] (2) Fertilization during the blooming period: in early April, when 80-90% of the macadamia nut A16 has faded,...

Embodiment 3

[0042] A method for integrated fertilization of macadamia nuts with water and fertilizer, comprising the following steps:

[0043] (1) Fertilization in the early stage of heading: In late February, when the branches of the macadamia nut O.C start to head, apply the fertilizer solution once with the integrated water and fertilizer system, first start the control system of the integrated water and fertilizer system, and perform blank irrigation with clean water. 7.2kg / plant, then switch to fertilizer solution irrigation, the fertilizer solution for irrigation is obtained by completely dissolving 3.98 parts of urea, 1.65 parts of potassium dihydrogen phosphate, and 1.00 parts of potassium chloride in water, the concentration is 2g / L, and the dosage is 107kg / plant, water and fertilizer were applied in the form of circular drip irrigation at 2 / 3 of the crown, and the irrigation flow rate was 20L / h;

[0044] (2) Fertilization during the blooming period: in late March when 80-90% of...

Abstract

The invention discloses a fertigation fertilizing method for macadamia nuts, and belongs to the field of agricultural production. According to the invention, water-soluble fertilizer is selected to prepare fertilizer liquid, different fertilizing schemes are used for the macadamia nuts in different growth stages, a fertigation system is used, the watering and fertilizing of the macadamia nuts arecarried out simultaneously, the labor and time are saved, the method is suitable for large-area planting of the macadamia nuts; the utilization rate of the water and fertilizer is high, and the yieldincreases by more than 20% per mu.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a method for fertilizing macadamia nuts with water and fertilizer integration. Background technique [0002] Macadamia ternifolia F.Muell, whose scientific name is Macadamia ternifolia F.Muell, belongs to the plant kingdom Angiosperm phylum Dicotyledonous plant class Longan order Longanaceae Macadamia is a perennial evergreen fruit tree. [0003] The kernels of macadamia nuts are rich in nutrients. The oil content of the kernels is as high as 75%-79%, which is much higher than that of ordinary edible vegetable oils. The main types are unsaturated fatty acids, mainly oleic acid and palmitic acid, which are easily digested and absorbed by the human body. It is good for your health and is an ideal cooking oil. In addition to containing a large amount of unsaturated fatty acids, it also contains a variety of essential amino acids and rich mineral elements, and is a high-qualit...
