Special compound fertilizer for macadimia nuts as well as package fertilizer and fertilization method of package fertilizer

Abstract

The invention discloses a special compound fertilizer for macadimia nuts as well as a package fertilizer and a fertilization method of the package fertilizer. The compound fertilizer comprises N, P2O5and K2O components with a weight ratio of (18-21.5):(3.6-4.3):(15-17.2), wherein the total nutrient content of N, P2O5 and K2O is 36.6-43%. The package fertilizer comprises a pre-flowering fertilizer, a fruit-protecting and fruit-strengthening fertilizer and an oil accumulation fertilizer which are all compound fertilizers, and a post-fruiting fertilizer composed of the compound fertilizer, an organic fertilizer and a micro-element fertilizer, and the micro-element fertilizer comprises borax, ferrous sulfate, magnesium sulfate and zinc sulfate heptahydrate. An application method comprises thefollowing steps: digging fertilization ditches along a crown drip line, uniformly applying the package fertilizer, covering the ditches with soil and conducting watering. The compound fertilizer canmeet the growth and development nutrient requirements of macadimia nuts, and resource waste and environmental risks are avoided; the package fertilizer and the fertilization mode can give play to thepotential of efficient nutrient utilization of root systems, and the fertilizer utilization rate is effectively increased; and healthy tree body building and sustainable orchard construction can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of new agricultural fertilizers, and relates to a special compound fertilizer for macadamia nuts, a set fertilizer and a fertilization method thereof. Background technique [0002] Macadamia nut, also known as Queensland fruit, Australian walnut and macadamia nut, belongs to the genus Macadamia in the dicotyledonous class Longanaceae. It is an evergreen tree fruit tree native to southeastern Queensland and northeastern New South Wales, Australia. Macadamia nuts are rich in nutrition, with a fat content of more than 78%. They are the raw materials of various high-end snacks and cosmetics. They are very popular in the international market and have a high economic value. They are known as the "Queen of Dried Fruits". [0003] The planting range of macadamia nuts has been gradually expanded in recent years. At present, it is mainly located between 34° north latitude (California, USA) and 30° south latitude (Sout...

AI Technical Summary

Problems solved by technology

However, the fertilization management of macadamia nuts in my country is still at an initial stage of exploration. The understanding of the reasonable fertilization period, fertilization quantity, application ratio of various nutrient elements, and application methods of macadamia nuts is relatively shallow, and the management is unscientific.

Unreasonable nutrient management and input is an important reason for the low yield of macadamia nuts. In view of the problems existing in the nutrient management of macadamia nuts in my country at the present stage, it is very important to propose a fertilization management plan suitable for macadamia nut planting in my country
