Embodiment 1

[0040] A method for cultivating twig grafted seedlings utilizing premature macadamia nuts, comprising the steps of:

[0041] (1) The selected premature macadamia nuts are 8-year-old mature natural fruit shedding, and the skin is complete, free from insect pests, and without mechanical damage. After removing the peel and shell of the premature macadamia nuts, the kernels are cleaned and disinfected, and the seedlings are obtained. Embryos are ready for use; the disinfection is to put the nuts into 40% sclerotia wettable powder diluted 1200 times and soak for 30 minutes, then put them into 50% triflubenazole diluted 1500 times and soak for 50 minutes, and then use aseptic Wash the seeds twice with water and dry them naturally for later use;

[0042] (2) After the matrix on the sand bed is sterilized, apply mixed medicament to it and mix evenly, then pour water until the matrix is ​​wet and ready for use; A combination of manganese zinc wettable powder, 6-benzyl adenine, and ind...

Embodiment 2

[0048] A method for cultivating twig grafted seedlings utilizing premature macadamia nuts, comprising the steps of:

[0049] (1) The selected premature macadamia nuts are 8 mature naturally shed fruits, and the skin is complete, free from insect pests, and without mechanical damage. After removing the skin and shell of the premature macadamia nuts, the nuts are cleaned and disinfected, and placed in aseptic Segment the nuts in the environment, divide each nut into 2 parts, and keep the germ in each part to get the seed embryo for later use; the disinfection is to put the nuts into 40% sclerotia net wettable powder in order to dilute 1150 times of liquid Soak for 50 minutes, then soak in 50% triflubenazole diluted 1450 times for 30 minutes, then wash the seeds with sterile water for 3 times, then dry them naturally for later use;

[0050] (2) After the matrix on the sand bed is sterilized, apply mixed medicament to it and mix evenly, then pour water until the matrix is ​​wet an...

Embodiment 3

[0056] A method for cultivating twig grafted seedlings utilizing premature macadamia nuts, comprising the steps of:

[0057] (1) The selected premature macadamia nuts are 7-ripe naturally shed fruit, and the skin is complete, free from insect pests, and without mechanical damage. After removing the skin and shell of the premature macadamia nuts, clean and disinfect the kernels, and place them in aseptic Segment the nuts in the environment, divide each nut into 4 parts, and keep the germ in each part to get the seed embryo for later use; the disinfection is to put the nuts into 40% sclerotia net wettable powder in order to dilute 1100 times of liquid Soak for 60 minutes, then soak in 50% triflubenazole diluted 1400 times for 20 minutes, wash the seeds with sterile water for 3 times, and then dry them naturally for later use;

[0058] (2) After the matrix on the sand bed is sterilized, apply mixed medicament to it and mix evenly, then pour water until the matrix is ​​wet and rea...

Abstract

The invention provides a method for culturing young branch grafted seedlings by using premature macadamia integrifolia, and relates to the technical field of macadamia integrifolia cultivation. Kernels of the premature macadamia integrifolia are put on a sand bed for accelerating germination, the seedlings are taken as rootstocks when stems grow to 5-10 cm in height after germination, and preparation is made for bud grafting of a new variety of macadamia integrifolia; and shoots begin to emerge four months after grafting, garden leaving and transplanting can be carried out after two crops of shoots emerge, the seedlings can grow strongly in 1.5 years, and fruit-bearing planting is achieved. The premature macadamia integrifolia seed resources are comprehensively utilized, the purpose of high new variety cultivation efficiency is achieved, the cultivation time is shortened, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of macadamia nut cultivation, in particular to a method for cultivating twig-grafted seedlings using premature macadamia nuts. Background technique [0002] Macadamia nuts are woody plants, and woody plants are difficult to grow through tissue culture. The normal maturity period of macadamia nuts is from September to October, but due to natural reasons such as typhoons, they will fall before they reach the maturity stage, and they will fall in July-August, that is, premature macadamia nuts, and this kind of fruit drop is 7-8 mature, It cannot be sold as a commodity, but throwing it away will cause waste of fruit resources. In order to make full use of this part of resources, it can be used as seed resources for new varieties. Especially for cultivating new varieties, the introduction of new varieties is expensive, and resources are few, this method can speed up the cultivation of new varieties. [0003] Tr...
