Embodiment 1

[0026] A method for dwarfing and densely planting macadamia nuts, comprising the following steps:

[0027] (1) Preparation of dwarfing substrate: The dwarfing substrate is composed of the following components in parts by weight: 80 parts of soil, 15 parts of decomposed pig manure, 10 parts of camellia cake, 8 parts of biogas residue, 5 parts of sodium humate, calcium 4 parts of magnesium phosphate fertilizer, 3 parts of humic acid, and 0.5 part of paclobutrazol; the preparation method of the dwarfing substrate is as follows: 1) uniformly mixing the components forming the dwarfing substrate to obtain a mixture; 2) adjusting the water content of the mixture to 55%, to obtain the dwarfing matrix;

[0028] (2) Hole digging: dig a planting hole in the planting site, and the size of the planting hole is 0.8m×0.8m×0.6m;

[0029] (3) Planting: Cross-plant with more than 2 dwarf grafted seedling varieties in each plot, and the planting density is 18 plants / mu. When planting, put seedl...

Embodiment 2

[0038] A method for dwarfing and densely planting macadamia nuts, comprising the following steps:

[0039] (1) Preparation of dwarfing substrate: The dwarfing substrate is composed of the following components in parts by weight: 100 parts of soil, 20 parts of decomposed pig manure, 15 parts of camellia cake, 12 parts of biogas residue, 7 parts of sodium humate, calcium 6 parts of magnesium phosphate fertilizer, 5 parts of humic acid, and 0.7 part of paclobutrazol; the preparation method of the dwarfing substrate is as follows: 1) mixing the components that form the dwarfing substrate evenly to obtain a mixture; 2) adjusting the water content of the mixture to 60%, to obtain the dwarfing matrix;

Abstract

The invention relates to a dwarfing and close planting method for Macadamia ternifolia. The dwarfing and close planting method has the advantages that a dwarfing medium is placed into each planting hole, thoroughly decomposed pig manure, camellia oleifera cake and biogas residues added into the dwarfing medium provide sufficient nutrients for Macadamia ternifolia seedlings, and soil looseness is achieved to benefit Macadamia ternifolia root system growth; sodium humate, calcium magnesium phosphate fertilizer and humic acid are added into the dwarfing medium, the roots of the Macadamia ternifolia seedlings are promoted to absorb paclobutrazol, the root systems of the Macadamia ternifolia are developed and deeply distributed, and the wind damage resistance of the Macadamia ternifolia is increased; the paclobutrazol is added into the dwarfing medium to promote Macadamia ternifolia dwarfing; mepiquat chloride is sprayed during branch thinning to promote Macadamia ternifolia dwarfing and increase the fruiting rate and yield of the Macadamia ternifolia; dwarfing elements are sprayed in spring and summer and abscisic acid is sprayed in autumn and winter during growth management, Macadamiaternifolia dwarfing is further induced, and the annual yield of the Macadamia ternifolia can be increased by 30-50%.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for dwarfing and densely planting macadamia nuts. Background technique [0002] Macadamia is a high-end economic crop in the tropics and subtropics. It has a dense canopy, shallow root system, and is not wind-resistant. It is suitable for planting on hills or flat land below an altitude of 1200m. It requires deep soil and good drainage. Irrigation conditions are available when there is water shortage in the dry season. The highest temperature in summer Generally, it does not exceed 35°C, and the highest temperature in winter is not lower than 15°C. Macadamia nuts are rich in nutrients, with an oil content of 70%-79%, rich in unsaturated fatty acids and rich in protein, calcium, phosphorus, iron, vitamin B1, vitamin B2 and 8 kinds of amino acids necessary for the human body. At the same time, the monounsaturated fatty acid in macadamia nut oil can reduce th...
