Problems solved by technology

[0003] Macadamia has a large amount of flowers, but its pollination mainly depends on wind pollination, while the surface of macadamia pistil stigma is very small, so the fruit setting rate is extremely low, only 0.1%-0.5%, resulting in low yield
Thus restricting the development of macadamia nuts

Embodiment 1

[0018] The pollen of the self-selected variety 109 was collected at 16:00-17:00 with the above-mentioned pollination tube, and the artificial pollination of the variety Own choice (hereinafter referred to as OC) was carried out at 8:30-9:00 the next day, and the average fruit setting rate was 4.38%. Much higher than the natural pollination fruit setting rate of 0.48%.

Embodiment 2

[0020] The pollen of the self-selected variety 109 was collected from 8:30-9:00 with the above-mentioned pollination tube, and artificial pollination was carried out on the variety OC from 8:30-9:00 on the same day. The average fruit setting rate was 5.31%, which was much higher than the natural pollination of 0.48%. Fruit set rate.

Embodiment 3

[0022] The pollen of the self-selected variety 109 was collected from 8:30-9:00 with the above-mentioned pollination tube, and the artificial pollination of the variety OC was carried out at 9:30-10:00 on the same day. The average fruit setting rate was 1.35%, which was higher than 0.48% of natural pollination. Rate.

Abstract

The invention relates to an artificial pollination method for macadamia nut, and particularly relates to an application method for artificial pollination of macadamia nut, pollen collecting time of macadamia nut, appropriate time of pollination and a pollination tube. The artificial pollination method comprises the following steps: selecting spica bloomed on the same day; opening the pollination tube to wrap the to-be-collected spica; closing the pollination tube and lightly rotating the pollination tube; when a layer of thin pollen can be seen on the inner wall of the pollination tube, gently opening the pollination tube; then wrapping the to-be-pollinated spica by using the pollination tube collecting the pollen, gently closing the pollination tube, gently rotating for 4-5 circles; and opening and taking down the pollination tube to complete the pollination. The pollination tube is used to collect pollen and pollinate, so the style of macadamia nut is little influenced; the fruit setting rate is greatly increased to 4-5% 0.1-0.5% which is the fruit setting rate of natural pollination. By virtue of the method to pollinate, the purpose that the flowers can be used to improve the setting rate can be achieved; and the fruit setting amount can be determined according to the load of the tree. The method is simple to operate, low in cost and easy to promote.

Description

technical field [0001] The invention relates to an artificial pollination method for fruit trees, in particular to an artificial pollination method for macadamia nuts, and belongs to the technical field of artificial pollination for fruit trees. Background technique [0002] Macadamia( Macadamia integrifolia ), also known as macadamia nut, originates in Australia and is the highest edible nut in the world. It has the reputation of "king of nuts" and "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] Macadamia has a large amount of flowers, but its pollination mainly depends on wind pollination, while the surface of macadamia pistil stigma is very small, so the fruit setting rate is extremely low, only 0.1%-0.5%,...
