Special flower and fruit retention type fertilizer for camellia oleifera and preparation method thereof

Abstract

The invention discloses a special flower and fruit retention type fertilizer for camellia oleifera. The special flower and fruit retention type fertilizer comprises urea, monoammonium phosphate, potassium sulfate, an active bio-organic fertilizer, mineral source fulvic acid, starch grafted acrylate and a medium trace element fertilizer. The preparation method comprises the following steps: uniformly mixing the active bio-organic fertilizer, urea, monoammonium phosphate, potassium sulfate, mineral source fulvic acid and the medium trace element fertilizer, and granulating through an ultralow-temperature granulator to obtain a semi-finished product of the granular fertilizer; spraying the semi-finished product of the granular fertilizer with grafted acrylate through an ultramicro atomizationspraying system for wrapping, and cooling and screening to obtain the special flower and fruit retention type fertilizer for camellia oleifera. On the basis of combination of organic and inorganic fertilizers, mineral source fulvic acid is matched, so that the growth of camellia oleifera root systems can be directly stimulated, the water absorption and fertilizer absorption capacities of the rootsystems are improved, the growth is promoted, and the flower and fruit retention rate is increased.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a flower-preserving and fruit-preserving type Camellia oleifera special fertilizer and a preparation method thereof. Background technique [0002] At present, my country's Camellia oleifera plantation basically adopts the extensive planting management mode of "human race and natural cultivation", which leads to low yield and difficult to guarantee the quality of Camellia oleifera. Camellia oleifera is a plant with the same period of flowers and fruits, and there is a rate of bud drop, flower drop and fruit drop of up to 80-90% per year, which is the saying "thousand flowers and one fruit". How to stabilize and improve Camellia oleifera production, the key is to improve the flower and fruit setting of Camellia oleifera, and at the same time preserve the flowers and fruits. [0003] Therefore, how to improve the flower setting and fruit setting of Camellia oleifera is a tech...
