Problems solved by technology

Due to the brittle wood, thin skin and high tannin content of macadamia nuts, the survival rate of conventional grafting seedlings is low, and it is difficult to meet production needs
In foreign macadamia nut grafting, before the scion is harvested, the branches to be used as the scion are usually circumcised or girdled in advance to increase the nutrient accumulation of the scion, thereby increasing the survival rate of the graft. This method is time-consuming and labor-intensive, and the production efficiency is low. Domestic No seedling unit adopts it; the conventional method currently used in our country is to graft seedlings, but the survival rate is not high
Therefore, the development of macadamia nuts in suitable areas is restricted

Abstract

The invention discloses a drug liquor composition for grafting and reproducing macadimia nut, a preparation method and an application thereof. The drug liquor composition consists of gibberellin, naphthylacetic acid, indolebutyric acid and thiophanate methyl. The scion is dipped by the drug liquor composition, after being grafted, the upper part of the scion is sealed by a biological membrane, the quantity of young sprout shooting can be increased by 16.7% to 40.1%, the average length of the young sprouts can be increased by 10.7% to 84.2%, and the average grafting survival rate reaches to 94.59%. Compared with the prior art, the invention improves the rafting survival rate by 66.90% to 72.09% and has low cost, convenient operation and easy scale promotion.

Description

technical field [0001] The invention relates to a technique for grafting and propagating fruit trees, in particular to a technique for grafting and propagating macadamia nuts. Background technique [0002] Macadamia integrifolia, also known as macadamia nut, is native to Australia and is the highest edible nut in the world. It has the reputation of "the king of nuts" and "the best edible nut in the world". my country began to commercially plant macadamia nuts in the late 1980s, mainly in Yunnan and Guangxi. The economic benefit of planting macadamia nuts is remarkable, and it is a rare characteristic economic tree species suitable for planting in my country's tropical regions. [0003] There are serious genetic variations in macadamia seedlings propagated by seeds. At present, macadamia seedlings are mainly raised by grafting at home and abroad. Due to the brittle wood, thin skin and high tannin content of macadamia nuts, the survival rate of conventional grafting seedling...
