Problems solved by technology

Nowadays, there are many researches on the application of water-retaining agents, but the application effect of water-retaining agents is closely related to climate, soil and crop types; the application effect of the same amount of water-retaining agents varies greatly in different regions, different crops, and different soils
At present, there are no technical reports on how to reasonably use water-retaining agents to overcome the constraints of drought on the yield of macadamia nuts. Therefore, how to overcome the constraints of drought on the yield of macadamia nuts, promote the growth and development of macadamia nuts, and the technology to increase its yield remains to be developed.

Embodiment 1

[0026] The present invention is implemented in the macadamia nut experiment base of Yunnan Institute of Tropical Crops Science, and Own Choice is selected as the implementation object.

[0027] The anti-drought method of this embodiment to improve macadamia nut production comprises the following steps:

[0028] In step (1), the row spacing of the macadamia tree is 5m×7m; in November, a symmetrical ditch with a length×width×depth of 100cm×20cm×30cm is excavated on both sides 40-45cm away from the trunk of the macadamia tree, and every grooves are dug along the two sides of the ditch;

[0029] Step (2), before the macadamia flowering period, mix the water-retaining agent and organic fertilizer evenly, and apply the symmetrical ditch method into the symmetrical ditch dug in step (1), and apply the evenly mixed water-retaining agent and organic fertilizer In the soil layer 20~25cm away from the surface, then perform a full irrigation. The water consumption for irrigation is 160kg...

Embodiment 2

[0034] The present invention is implemented in the macadamia nut experiment base of Yunnan Institute of Tropical Crops Science, and Own Choice is selected as the implementation object.

[0035] The anti-drought method of this embodiment to improve macadamia nut production comprises the following steps:

[0036] Step (1), the row spacing of the macadamia tree is 5m×7m; in December, a symmetrical ditch with a length×width×depth of 100cm×20cm×30cm is excavated on both sides 45-50cm away from the trunk of the macadamia tree, and every grooves are dug along the two sides of the ditch;

[0037] Step (2), before the macadamia flowering period, mix the water-retaining agent and organic fertilizer evenly, and apply the symmetrical ditch method into the symmetrical ditch dug in step (1), and apply the evenly mixed water-retaining agent and organic fertilizer In the soil layer 25~30cm away from the surface, and then perform a full irrigation, the water consumption for irrigation is 120k...

Embodiment 3

[0042] The present invention is implemented in the macadamia nut experiment base of Yunnan Institute of Tropical Crops Science, and Own Choice is selected as the implementation object.

[0043] The anti-drought method of this embodiment to improve macadamia nut production comprises the following steps:

[0044]Step (1), the row spacing of the macadamia tree is 5m×7m; in December, a symmetrical ditch with a length×width×depth of 100cm×20cm×30cm is excavated on both sides of the 43~46cm away from the trunk of the macadamia tree, and every Grooves are dug along the two sides of the ditch;

[0045] Step (2), before the macadamia flowering period, mix the water-retaining agent and organic fertilizer evenly, and apply the symmetrical ditch in the symmetrical ditch dug in step (1), and apply the evenly mixed water-retaining agent and organic fertilizer In the soil layer 24~27cm away from the surface, and then perform a full irrigation, the water consumption for irrigation is 140 kg ...

Abstract

The invention belongs to technical field of production increase of agriculture and forestry industrial crops, and particularly relates to a method for overcoming the restriction of draught to the yield of macadamia nut, promoting the growth and development of macadamia nut, and improving the yield of macadamia nut. The method adopts the following technical scheme: the row spacing of macadamia nut trees is 5 m * 7 m; digging symmetrical trenches on the two sides 40-50 cm from the main trunks of the trees during November and December; digging gutters on the two sides of each trench along the trench; after uniformly blending a water-retaining agent with an organic fertilizer, applying the blended materials in soil layers in the trenches in a symmetrical trench way, wherein the soil layers are 20-30 cm from the land surface, and fully watering the soil; after the water-retaining agent fully absorbs water, burying the materials with 15-20 cm capping mass; burying 10-15 cm of fruit shells, weeds or leaves or a mixture of a plurality of the three materials; the dosage of the water-retaining agent for each tree is 300-450 g; the dosage of the organic fertilizer for each tree is 5-15 kg. Compared with conventional irrigation methods, the method can retain and save water and improve the yield of macadamia nut.

Description

technical field [0001] The invention belongs to the technical field of increasing production of agricultural and forestry economic crops, and in particular relates to a method for overcoming the restriction of drought on the yield of macadamia nuts, promoting the growth and development of macadamia nuts, and increasing the yield. Background technique [0002] Macadamia( Macadamia spp . ) is an evergreen tree of the genus Macadamia F.Muell of the Proteaceae family (Proteaceae). It is native to Australia. Its nuts contain 65% to 83% fat and are rich in a variety of unsaturated fatty acids and essential amino acids. , trace elements and vitamins, long-term consumption helps to reduce total blood cholesterol, prevent arteriosclerosis, reduce platelet viscosity, and reduce the incidence of heart disease, myocardial infarction and other cardiovascular diseases. Macadamia nuts were commercially grown on a large scale in Hawaii in 1948, so they are also called macadamia nuts. At ...
