Problems solved by technology

[0003] Macadamia nuts are generally propagated by grafting, which has two main defects: on the one hand, the traditional grafting method has a low survival rate, generally only about 50%, and a worker can graft about 200 plants per day, and it is estimated that half of them will survive; On the other hand, macadamia nut grafting takes a long time to grow seedlings. The traditional macadamia seedling raising method is to graft when the rootstock is 20-30cm away from the ground and the stem thickness reaches 0.7-1.2cm. Rootstocks that meet this condition must be at least It has grown for more than 12 months and under good management, it can emerge from the nursery 6 months after grafting, and it takes at least 1.5-3 years from sowing to the emergence of asexual seedlings

Embodiment 1

[0030] A cultivation method for improving the grafting survival rate of macadamia nuts, comprising the following steps:

[0031] The cultivation of step A, stock:

[0032] Step 1) Soak the macadamia nut seeds in the first soaking solution at 25°C for 4 hours before sowing, remove the seeds floating on the liquid surface, scoop up the rest of the seeds, wash them with clean water, and place them in a constant temperature oscillator loaded with the second soaking solution In, shake and soak 15h, control the temperature of the second soaking solution to be 40°C, take out the soaked seeds, wherein the first soaking solution is a trisodium phosphate aqueous solution with a mass fraction of 0.5%, and the second soaking solution consists of 24 parts by weight of chitosan, 15 parts by weight of gibberellin, 30 parts by weight of egg vinegar and 1000 parts by weight of deionized water are made;

Abstract

The invention discloses a cultivation method for increasing the grafting survival rate of macadimia nuts. The method includes the following steps of cultivating stock, wherein the position, 8 cm away from the surface of a sand bed matrix, on the face of the upper portion of the stock is cut to form a notch with the length of 3 cm after 5-7 leaves grow on a stock seedling, and the middle of the notch is dug to form a cylindrical blind hole with the length of 1.5 cm; processing a scion, wherein an inclined face notch is formed by shearing the scion from the position 3 cm away from the base part of the scion to the base part, a cylindrical protrusion which is 1 cm long and matched with the cylindrical blind hole of the stock seedling is reserved in the middle of the inclined face notch, a protection agent is aligned with the inclined face notch and the cylindrical protrusion, and the inclined face notch and the cylindrical protrusion are smeared with the protection agent; primary grafting is conducted, wherein grafting promoting agent diluent is dropwise added into the cylindrical blind hole of the stock seedling, the cylindrical protrusion of the scion is aligned with the cylindrical blind hole of the stock seedling, and the butt joint inclined face of the cylindrical protrusion and the cylindrical blind hole is coated with grafting promoting agent diluent so that the stock seedling and the scion can be tightly combined and primary grafting can be completed. By means of the method, the grafting survival rate reaches up to 91.7%.

Description

technical field [0001] The invention relates to the field of cultivation of macadamia nuts. More specifically, the invention relates to a cultivation method for improving the grafted survival rate of macadamia nuts. Background technique [0002] Macadamia nuts, also known as Queensland chestnuts and macadamia nuts. Its kernels are rich in unsaturated fatty acids, proteins, vitamins, etc., with high nutritional value and unique flavor, known as the "king of dried fruits". The market prospect of macadamia nuts is promising, with good ecological and economic benefits. It is an edible nut with high oil content, rich nutrition and unique flavor. It has been in short supply in the international market. [0003] Macadamia nuts are generally propagated by grafting, which has two main defects: on the one hand, the traditional grafting method has a low survival rate, generally only about 50%, and a worker can graft about 200 plants per day, and it is estimated that half of them will...
