Embodiment 1

[0024] Example 1 The following steps were used to transform macadamia orchards with low yield and low efficiency that had been planted for 35 years, with closed canopies, serious pests and diseases, and mixed varieties:

[0025] (1) Retracting and pruning to renew the tree crown: After harvesting the fruits in autumn, select old trees with fewer fruiting branches in the inner chamber of the tree and more closed peripheral branches at intervals of 1 to 2 between the rows. Carry out retraction and re-cutting; the method of retracting and re-cutting is to retract and re-cut the main branch, and select an auxiliary branch at the retracted place, apply wound healing agent on the wound immediately after re-cutting, and wrap the tree body Put on the sunshade net and pour water in time to avoid the sun from burning the bark, promote the rapid healing of the wound, and make the main branch re-grow new shoots; In addition, keep 3~5 strong branches on each main branch; when the remaining...

Embodiment 2

[0033] Example 2 The following steps were used to transform macadamia orchards with low yield and low efficiency that had been planted for 28 years, with closed canopies, severe pests and diseases, and degraded varieties:

[0034] (1) Retracting and pruning to renew the tree crown: After harvesting the fruits in autumn, select old trees with fewer fruiting branches in the inner chamber of the tree and more closed peripheral branches at intervals of 1 to 2 between the rows. Carry out retraction and re-cutting; the method of retracting and re-cutting is to retract and re-cut the main branch, and select an auxiliary branch at the retracted place, apply wound healing agent on the wound immediately after re-cutting, and wrap the tree body Put on the sunshade net and pour water in time to avoid the sun from burning the bark, promote the rapid healing of the wound, and make the main branch re-grow new shoots; In addition, keep 3~5 strong branches on each main branch; when the remaini...

Embodiment 3

[0042] Embodiment 3 adopts the same steps of implementation 2 to transform the low-efficiency and low-yield macadamia orchards that have been planted for 25 years, the canopy is closed, the disease and insect pests are serious, and the variety is degraded: wherein, the difference is:

[0043] Step (1) is different from the wound healing agent formula used in Example 2, specifically as follows: 6% thiophanate-methyl, 0.3% urea, 0.1% potassium dihydrogen phosphate, 0.1% sodium naphthalene acetate, 58% calcium carbonate, 25% Water, 10.5% lard;

[0044] Step (3) Apply 35 kg of compound fertilizer to each plant (including 30 kg of decomposed organic fertilizer and 5 kg of compound fertilizer);

[0045] The fertilizer added in the first 4 periods of step (5) is compound fertilizer, and the dosage is 2 kg per plant; after fruit picking, the amount of fertilizer per plant is 10 kg of decomposed pig manure, 2 kg of cake fertilizer, 0.5 kg of compound fertilizer and 0.2 kg of quicklime....

Abstract

The invention discloses a method for solving low yield and low efficiency problems of an aged and closed macadamia garden. The method includes the steps that firstly, shrinking and heavy pruning are conducted to rejuvenate tree crowns ; secondly, shaping and pruning are conducted to rejuvenate branch groups; thirdly, deep plowing and soil improvement are conducted to rejuvenate root systems; fourthly, seeds are changed in batches, and pre-transplanting is updated; fifthly, reasonable fertilizer and water management is conducted; sixthly, topdressing is conducted outside roots, and flower and fruit retention is achieved; seventhly, diseases, pests and rat damage are prevented. By means of the method, after fruits are harvested in autumn, the low-yield low-efficiency aged and closed macadamia garden is improved, so the tree crowns of the garden can be rejuvenated, variety configuration is reasonable, soil fertility is quickly enhanced, diseases, pests and rat damage are prevented in time, flowering, fruit setting and fruit development are promoted, yield of single plants is greatly increased, and quality of single plants is greatly improved. After the method is implemented, productivity of the aged and closed macadamia garden can restore the level in the full fruiting period within 2-3 years, 10 kg or above of fruits with shells are produced on each plant in average, benefits are improved by 40% or above, accordingly the low yield and low efficiency problems of the aged and closed macadamia garden are solved, and sustainable development of the macadamia industry is promoted.

Description

technical field [0001] The invention relates to a method for planting and managing macadamia orchards, in particular to a method for solving low-yield and low-efficiency in aged closed macadamia orchards, and belongs to the technical field of fruit tree cultivation and management. Background technique [0002] Macadamia is a characteristic subtropical fruit with distinctive regional characteristics, unique nutritional value and high economic added value. component. [0003] The macadamia nut industry in my country started relatively late, and the commercial cultivation of macadamia nuts began in the late 1980s. By the end of 2015, my country had planted more than 1.5 million mu of macadamia nuts in Yunnan, Guangxi and other places. According to the development trend and related plans of the macadamia nut industry in various production areas in my country, the planting area of ​​macadamia nuts in my country will exceed 3.5 million mu during the "13th Five-Year Plan" period....
