Problems solved by technology

This method can advance the fruit-bearing period of nuts by 2 to 3 years, and it is also conducive to the promotion of good varieties, but the biggest shortcoming is that due to the thinner bark of macadamia nuts, the subcutaneous cambium is thinner, and it is not easy to heal and grow when grafted with seedlings as rootstocks. Low, strict requirements on grafting season, general survival rate is 15-40%, even if it is operated by the most skilled personnel in the best season, it can only reach about 70%, the rate of emergence is low, the management cost is high, and the corresponding economic benefits Low

Embodiment 1

[0009] Example 1: Collect the fruit of the high-yield macadamia mother tree "H2" in October, discard the green fruit peel within two days, soak it in 0.3% carbendazim aqueous solution for 2-3 days, and put it in the sun for half a day to let it dry The hard shell is cracked, and then sowed on the seedbed of the bud stock with a row spacing of 4×5 cm, and managed according to the conventional method. After 30 to 70 days, the bud stock seedlings grow to 5 to 18 cm and the stems are 0.2 to 0.4 cm thick. Take it out carefully. Cut off the upper end, leaving 3-5cm lower seedling stems, deflect to one side with a knife, cut the broken head joint longitudinally on the seedling stems, the depth of the incision is 1.2-2cm, soak in two ten thousandths of "Bihu "Stand-by in the aqueous solution; select branches of 0C varieties of fine-species mother trees that were born in the same year and have been lignified, each branch is 30-40cm long, and contains six impellers. Pay attention to mois...

Embodiment 2

[0010] Example 2: Collect the mature fruit of macadamia nut 0C improved mother tree in October of the first year, peel off the green fruit skin within two days and place it on an indoor fruit rack to let it dry and store naturally, and take out the stored nut seeds in the first ten days of March of the second year , after soaking in 0.5% carbendazim or methylbutazine aqueous solution for 3 days, put it in the sun for half a day, let the hard shells crack, sow on-demand on the bud stock seedling bed with a plant row spacing of 5×5cm, and According to conventional seedling management, after 20-30 days, the bud stock seedlings grow to 5-15 cm, and when the stems are 0.2-0.4 cm thick, carefully remove and cut off the upper end of the bud stock seedlings, leaving 3-5 cm lower seedling stems, off-center and parallel to the row of stems Cut the head, the depth of the incision is 1.2-2cm, and soak it in the 2 / 10,000 "Bihu" aqueous solution for later use; select the branch of the macada...

Abstract

The invention relates to a bud stock grafting method of Australian nuts. The grafting method comprises the following steps of: using Australian nuts for dibbled planting and culturing seedling sproutsof the nuts as bud stocks, using one-year-old branches which are lignified on the seed tree of Australian nuts as scion and grafting the branches on the bud stocks, temporarily planting the bud stocks in nutritional bags, planting the obtained nutritional bags with bud stocks on a seedling bed with shade net sheds and mulching film convex sheds and controlling the temperature and relative humidity in the sheds. The bud stock grafting method fully exerts the characteristics of strong regeneration capacity and vigorous growth of young tissues of the bud stocks, and effectively overcomes the defects that the forming layers of the young seedling stocks of the nuts are thin and the growth and coalescence are harder with the scions and grafting survival rate is low, thus greatly improving the grafting survival rate of the Australian nuts by more than 20 percent, shortening the period of out of nursery by more than one year, reducing the culturing cost of seedlings and increasing the economic benefit.

Description

Technical field: [0001] The invention belongs to plant grafting technology, in particular to a macadamia nut bud stock grafting method. Background technique: [0002] Macadamia nuts, also known as macadamia nuts, are known as the "king of nuts" because of their rich nutritional value and economic value. In order to improve its economic properties over the years, people have done a lot of research from various aspects, and have also made great progress. For example, in order to overcome the problem of long fruit-bearing period of planting seedlings, seedling grafting technology is generally adopted at home and abroad. The seedlings of seedlings are used as rootstocks, and the branches of high-quality varieties are used as scions for grafting. This method can advance the fruit-bearing period of nuts by 2 to 3 years, and it is also conducive to the promotion of good varieties, but the biggest shortcoming is that due to the thinner bark of macadamia nuts, the subcutaneous cambi...
