A method to solve the low yield and low efficiency of old closed macadamia orchard

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....
