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

Abstract

The invention discloses a special compound fertilizer for macadamia nuts, its set fertilizer and a fertilization method. The compound fertilizer includes N and P with a weight ratio of (18-21.5): (3.6-4.3): (15-17.2) 2 o 5 and K 2 O components, and N, P 2 o 5 and K 2 The total nutrient content of O is 36.6-43%. The set fertilizer includes pre-flowering fertilizer, fruit-preserving and strong-fruiting fertilizer and oil-accumulating fertilizer, all of which are compound fertilizers, as well as post-fruiting fertilizer composed of compound fertilizer, organic fertilizer and micro-fertilizer. Micro-fertilizer Including borax, ferrous sulfate, magnesium sulfate and zinc sulfate heptahydrate; the method of application is to dig a fertilization ditch along the drip line of the tree crown, cover the soil and water after uniform application. The compound fertilizer of the present invention can meet the nutrient requirements for the growth and development of macadamia nuts, avoiding waste of resources and environmental risks; the set fertilizer and fertilization method can exert the potential of high-efficiency utilization of nutrients by the root system, and effectively improve the utilization rate of fertilizers; Sustainable orchard construction.

Description

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