Problems solved by technology

Therefore, selenium-enriched macadamia nuts have gradually become a hot spot in macadamia planting research. Most of the existing selenium-enriched macadamia nuts are sprayed with selenium-containing foliar fertilizers at the early flowering stage of macadamia nuts. This method of fertilization consumes a lot of selenium fertilizers and will affect Pollination of macadamia nuts, thereby reducing macadamia yields

Abstract

The invention relates to a cultivation method of selenium-enriched macadimia nuts. The cultivation method comprises the steps of land block selection, seed planting, fertilization management, water management, pest and disease damage control, beekeeping and proper harvesting. According to the cultivation method of the selenium-enriched macadimia nuts, multiple varieties of grafted seedlings are selected for planting, the pollination success rate of the macadimia nuts can be increased, and then the yield of the macadimia nuts can be increased; in the flowering phase, beekeeping is conducted tofacilitate pollination, and the yield of the macadimia nuts is further increased; sodium selenite and potassium humate are added in biogas slurry, macadimia nut trees are promoted to absorb selenium,the selenium content of the macadimia nuts reaches 0.35 mg/kg-0.55 mg/kg, an appropriate amount of nicotinic acid is added in selenium-enriched fertilizer, the flowering phase of the macadimia nut trees can be shortened to be 15-18 days by adding nicotinic acid, the fruit ripening time of the most macadimia nuts is consistent, and macadimia nut fruits can be harvested mechanically conveniently.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a cultivation method for selenium-enriched macadamia nuts. Background technique [0002] Macadamia nut alias: Queensland chestnut, macadamia walnut, macadamia nut, Queensland fruit, is a tree nut native to Australia. Macadamia nuts are evergreen trees and dicotyledonous plants. The crown is tall, with 3-4 whorls of leaves, lanceolate, leathery, smooth, with spiny serrations on the edges. Racemes axillary, beige flowers, spherical fruit, leathery, hard endocarp, beige to light brown kernels. It is suitable for growing in mild, humid and windy areas. Among the many dried fruits in the world, macadamia nuts have the highest economic value and have always enjoyed the reputation of "the king of dried fruits". Distribution area: Eastern Australia, New Caledonia, Sulawesi, Indonesia. In addition, macadamia nuts also have high nutritional and medicinal value. [0003]...
