Macadamia nut (Macadamia integrifolia) is a perennial evergreen plant of the genus macadamia of the class of the family of the genus dracaena, the aliases kunski chestnut, juglans mandshurica and hawaii fruit. Macadimia nuts are favored in the international market due to their high nutritional and economic value. The macadimia nut has rich nutrition and 70-79% of oil content, is rich in various unsaturated fatty acids such as oleic acid, palmitic acid, linoleic acid and the like, has the effects of regulating organism cholesterol and reducing occurrence of cardiovascular diseases, and can be used as high-grade edible oil or skin care product base oil. The kernel of the food is crispy and delicious, and the food is delicious and delicious, is usually used as a raw material of various high-grade desserts, and is deeply favored by the public.
At present, the macadimia nuts are mainly distributed in regions such as Yunnan, guangxi, guangdong, hainan, fujian, zhejiang, sichuan and the like in the planting regions of China. As the consumption of macadimia nuts increases, the planting area of macadimia nuts is also expanding. The current planting method is a close planting method, a direct field planting method for expanding the row spacing, and the method is used for improving the land utilization rate or the yield. The fruiting characteristics of the macadimia nut are the results of the small branches of the inner bore, so that more small branches of the results are reserved as much as possible under the condition of ensuring ventilation and ventilation during trimming. How to cultivate more fruiting branches and reduce the sun shielding under the condition of fully utilizing the land and illumination is a novel planting method which needs to be explored at present.

Aiming at the problems, the invention provides a planting method for plane fruiting of macadimia nuts, which is characterized in that the lateral branches, the fruiting branches and the trunk are controlled to be on the same plane, so that shielding among the lateral branches, the fruiting branches and the trunk is reduced, ventilation and ventilation are realized, bee pollination is realized, more fruiting branches are favorably cultivated, and meanwhile, mixed seeds of early, middle and late maturing varieties are combined, so that the pollination success rate is improved.
The invention is realized by the following technical scheme:
a planting method of macadimia nut plane fruiting comprises the following steps,
(1) And (3) mounting a planting frame: determining planting rows according to the planting density of the macadimia nuts of 1.5-2 multiplied by 3-4 meters, arranging upright posts at the positions of the left and right sides of the macadimia nut planting rows at intervals of 0.75-1.0m, and binding the upright posts by steel wire bundles to form a multi-layer net rack, wherein the intervals between the steel wire bundles of each layer are 30-60cm;
(2) Selecting and grafting seedlings: healthy seedlings with the plant height of 50-55cm are selected as stocks, and are planted obliquely on planting rows among the upright posts, and an angle of 30-60 degrees is formed between the healthy seedlings and the ground; selecting mature macadimia nut parent tree with good characters or branches with strong growth and no plant diseases and insect pests and with a length of 5-10cm on a rare macadimia nut sapling tree as scions, firstly placing the scions into a carbendazim solution for soaking and sterilizing, then placing the scions into a solution containing cytokinin for soaking for 20-30 minutes, and placing the scions in a shade place for standby; cutting off the position of the stock with the height of 5-10cm, grafting the scion at the cutting-off position of the stock by adopting a split grafting and/or bark grafting method, and wrapping the interface by using a film; removing the film after the young shoots of the scions are fully aged once;
(3) Shaping a trunk: culturing a trunk after grafting, and obliquely moving the trunk to the direction of the upright post by using a rope when the trunk grows to 0.8-1.2m, wherein the trunk and the ground are kept at an angle of 30-60 degrees, and the rope is tied on a steel wire; when the trunk grows to 1.5-2.0m, fixing the trunk to the upright post end of the first layer of steel wire, reversing the trunk, continuing to drag and shape the trunk to the upright post end of the other side of the second layer of steel wire, and sequentially and spirally and alternately growing to form a plurality of layers;
(4) Culturing lateral branches: on the trunk of each layer, one side branch is reserved at intervals of 10-15cm, the side branches are alternately pulled in directions, ropes for pulling are fixed on steel wires or upright posts, and the side branches and the trunk are kept on the same plane.
As the optimization of the technical scheme, the distance between the first layer of steel wire and the ground is 60-80cm, and the distance between the second layer of steel wire and the steel wire is 30-40cm.
Preferably, the height of the upright post is 3.0-3.5m.
Preferably, the plane between the upright posts faces east or west. After the later-stage macadimia nut is planted, the branches are distributed fully to obtain sunlight.
As the optimization of the technical scheme, the side branches only remain the side branches in the plane direction of the upright post to be cultivated into the fruit branches, and the side branches in other directions are trimmed and removed.
Preferably, the lateral branches in the same direction are spaced by 20-30cm.
As the optimization of the technical scheme, the lateral branches of two adjacent layers are reserved in a staggered manner, so that the shielding caused by the overlapping in the same direction is avoided.
As the optimization of the technical scheme, the macadimia nut varieties which are early, medium and late maturing are grafted in the same orchard; the grafting ratio of the early, middle and late maturing macadimia nut varieties is 1:1-2:1. Thus, the flowering period is just staggered, the late flowers of the early-maturing varieties collide with the early flowers of the middle-maturing varieties, the late flowers of the middle-maturing varieties collide with the early flowers of the late-maturing varieties, the pollination is more complete, the pollination rate of the orchard is improved, and the fruiting rate and the yield are improved.

The fertilizing method and the pest control method adopt the methods in the prior art.
Compared with the prior art, the invention has the beneficial effects that:
(1) The invention adopts an inclined seed mode for planting, can quickly stimulate lateral buds to germinate, can form fruiting branches in advance, and can promote lateral buds to grow. And the macadimia nut trunks are alternately grown in an inclined seed spiral manner, so that the length of trunks can be extended, more fruiting small branches are cultivated, lateral branches are alternately distributed and branched, the distance is large, the space is transparent, excessive shielding can not be generated, and good illumination and bee pollination effects of branches and leaves can be ensured.
(2) The planting method can lead the trunk to exceed 14 meters under the condition of controlling the height of the tree to be 4 meters, and has similar effect with the conventional tree height of 14 meters. Compared with the height of 14 meters, the invention is more convenient for daily management such as pruning of branches, pruning after harvest, fruit harvest and the like. Compared with the conventional existing macadimia nut planting method, the branches are on the same plane, and rapid pruning is facilitated. Meanwhile, the branches are pulled, are firmer and wind-resistant, and the risk and loss of branch blowing caused by typhoon weather in 7-9 months are reduced.
(3) The existing macadimia nut planting methods are all vertical planting and growing, so that the top is dominant, and growth hormone is concentrated at the top, so that branches at the upper part germinate and grow faster; according to the method, the macadimia nut seed planting seedlings are planted obliquely, the growth hormone position effect is adjusted, the lateral buds are promoted to germinate, the lateral buds obtain uniform illumination conditions, the nutrition space of the lateral buds is optimized, more lateral bud branches can be grown rapidly, and the fruiting branches are cultivated.
(4) The distance between the first layer of steel wires and the ground is doubled compared with that between the second layer of steel wires and the ground, so that the situation that the inclination is too large due to too small angle when seedlings grow is ensured, the probability of pathogen infection is avoided and reduced, the transportation of moisture and nutrients of the seedlings is facilitated, and the growth is promoted.
(5) According to the method, 7-20 lateral branches are reserved on each layer of trunk, and can be cultivated into fruiting branches, the branches are basically positioned on the same plane, so that ventilation and ventilation are realized, the pollination rate is high, and flowers are exposed to the outside and are more easily attracted to insects such as bees, so that the pollination effect is ensured, the yield is improved, and the fruit quality is improved.

grafting early, medium and late maturing macadimia nut varieties in the same orchard; grafting ratio of early (OC), middle (Guifei No. 1) and late (695) ripe macadimia nut varieties is 1:2:1.
(3) Shaping a trunk: culturing a trunk after grafting, and obliquely moving the trunk to the direction of the upright post by using a rope when the trunk grows to 1.0-1.2m, wherein the trunk and the ground are kept at an angle of 35 degrees, and the rope is bound on a steel wire; when the trunk grows to 1.5-2.0m, fixing the trunk to the upright post end of the first layer of steel wire, reversing the trunk, continuing to drag and shape the trunk to the upright post end of the other side of the second layer of steel wire, and sequentially and spirally and alternately growing to form a plurality of layers;
(4) Culturing lateral branches: on the trunk of each layer, every 15cm interval is reserved with a side branch, the side branches are alternately pulled in direction, a rope for pulling is fixed on a steel wire or a column, and the side branches and the trunk are kept on the same plane. The side branches in the same direction are spaced by 30cm, only the side branches in the plane direction of the upright post are reserved for culturing into the fruit branches, and the side branches in other directions are trimmed and removed. The lateral branches of the adjacent upper and lower layers are reserved in a staggered way. As shown in fig. 4.
Comparative example 1
The row spacing was determined to be 2 x 4 meters using the existing conventional land-based method of planting macadamia nuts. The trunks and fruiting lateral branches were cultivated normally. Daily management and fertilizer application were carried out as normal as required in examples 1-3, with regular planting pruning, taking care of ventilation.
The data of the experimental procedures of examples 1-3, comparative example 1 are recorded in the following table 1:
table 1 record of macadamia nut yield
As shown in the table, although the branches of the lateral branches of the Australian nut trees obtained by the planting method are few, the flowering rate can reach more than 90% due to sufficient illumination obtained by the planar planting method, the lateral branches are basically sun-facing, the bee pollination effect is good, so that the fruits are early, the yield of the first year is 12.09-46.1% higher than that of the comparative example 1, and the yield of the high-yield period is 20-30% higher than that of the comparative example 1. The method of comparative example 1 can cultivate a large number of branches in the bore, but the flowering rate is only 50 to 60% and the pollination rate is lower, usually only about 30%, because the bore is relatively shaded. If the flowers meet the rainy days in the flowering phase, the flowers are particularly easy to annoy, the flowers are out of date, and the pollination success rate is lower.
