Method for improving fruit setting rate of macadamia by artificial assisted pollination

Abstract

The invention discloses a method for improving the fruit setting rate of macadamia by artificial assisted pollination. The method includes the steps of 1, evenly spraying pollination auxiliaries on apollen donor tree and a pollen receptor tree with a sprayer; 2, slightly sweeping inflorescences in full bloom on the pollen donor tree along the crown or the inner chamber of the pollen donor tree with a degreasing cotton ball to enable the pollen to be stained on the surface of the degreasing cotton ball; 3, using the degreasing cotton ball stained with the pollen to touch the inflorescences infull bloom on the pollen donor tree along the crown or the inner chamber of the pollen donor tree and completing pollination after contact; 4, replacing a new degreasing cotton ball when the density of the same is higher than 0.20g/cm<3>, wherein the degreasing cotton ball can be used repeatedly. The auxiliaries used in the method can increase pollen stickiness, make it easier to collect the pollen and perform pollination, and meanwhile, promote the affinity between the pollen and stigma and pollen germination; with the method, the fruit setting rate of the macadamia is increased by 15-30%, the yield of the macadamia is significantly increased, and planting benefit of the macadamia is increased.

Description

technical field [0001] The invention belongs to the pollination technology of agricultural and forestry economic crops, and in particular relates to a method for increasing the fruit setting rate of macadamia nuts through artificial assisted pollination. Background technique [0002] Macadamia spp. is an evergreen tree of the genus Macadamia F.Muell. of the family Proteaceae. It is native to the subtropical rainforests of Queensland and New South Wales, Australia, but large-scale commercial planting began in 1948. In Hawaii, also known as macadamia nut. Its nuts are rich in a variety of unsaturated fatty acids and essential amino acids, trace elements and vitamins. The content of monounsaturated fatty acids and palmitoleic acid is also extremely rich. It can be eaten directly or processed into high-grade edible oil. Eating can help reduce blood total cholesterol, prevent arteriosclerosis, reduce platelet viscosity, and reduce the incidence of heart disease, myocardial infar...

Problems solved by technology

[0004] Macadamia is an insect-pollinated plant and has partial self-incompatibility. This characteristic leads to low pollination success rate, low fruit set rate, and low yield, which is one of the important factors affecting its planting efficiency.

In production, pollination trees are often used to increase the fruit setting rate, but at present, many domestic orchards have unreasonable or even no pollination trees, resulting in low pollination success rate and fruit setting rate in these macadamia orchards, seriously affecting the orchard Yield

[0005] Chinese patent documents "A method for artificial pollination of macadamia nuts" (patent application number: CN201210262930.5), "A method for improving the efficiency of hybrid pollination of macadamia nuts" (patent application number: CN201410233516.0), "A hybrid macadamia nut Breeding method" (patent application number: CN201410234111.9) discloses a method for artificial pollination of macadamia nuts using test tubes or pollination tubes, but this method is only suitable for small-scale artificial pollination and hybrid breeding, even if a small amount of Pollination also requires a lot of labor; at the same time, because there is no pollination aid sprayed, it is difficult for pollen to adhere to the test tube or pollination tube wall, and the operation efficiency is not high. It takes several days to complete the pollination of a macadamia tree, and cannot Artificial assisted pollination for large-scale macadamia orchards

At present, there is no technical report on the use of artificial assisted pollination to increase the fruit setting rate of macadamia nuts that can be used in large-scale production. Therefore, the technology of using artificial assisted pollination to increase the fruit set rate of macadamia nuts that is suitable for large-scale production needs to be developed
