Medicament for improving fruit setting rate and yield of macadamia nuts and preparation and use methods thereof

Abstract

The invention discloses an agent for improving the fruit setting rate and yield of macadamia nuts and a preparation and use method. The agent for improving the fruit setting rate and yield of macadamia nuts is prepared from a first agent, a second agent and a third agent, the first agent is characterized by being prepared from zeatin, gibberellin, alpha-naphthylacetic acid, compound sodium nitrophenolate, soya bean lecithin, sunflower lecithin, borax, monopotassium phosphate, sodium humate and microelement fertilizer, wherein the first agent is used for improving the fruit setting rate of macadamia nuts; the second medicament is characterized by reducing the fruit dropping rate of macadamia nuts and is prepared from brassinolide, 6-benayl aminopurine and sodium citrate; the third agent is an organic chelated sugar alcohol calcium leaf fertilizer and is characterized by reducing the cracking rate of macadamia nuts; under the synergistic effect of the first agent, the second agent and the third agent, the fruit setting rate of the macadamia nuts can be increased, the fruit dropping rate and the fruit cracking rate are reduced, and the yield of the macadamia nuts is increased.

Description

technical field [0001] The invention relates to the technical field of macadamia nut planting, in particular to a medicament for improving the fruit setting rate and yield of macadamia nuts, and a preparation and use method. 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 to 4 leaves in whorls, 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". The kernel of macadamia nuts is rich in nutrition (milky white), the exocarp is turquoise, the endocar...

Problems solved by technology

[0003] At present, the problems existing in the planting process of macadamia nuts are: 1) the success rate of natural pollination is not high, and artificial pollination is needed to increase pollination; 2) the fruit setting rate is extremely low (about 0.3%); 3) the fruit stalk is brittle and extremely Easy to break, causing young fruit to fall off, further reducing fruit setting rate and yield
