Book

In order to produce more food, humans began to apply chemical fertilizers at the beginning of the last century, which artificially changed the evolution process of the soil, so that the natural weathered minerals in the existing agricultural production process could not meet the needs of rapid crop growth. Lack of nutrients and the need for artificially assisted additions. However, crops require up to 17 nutrients, including carbon, hydrogen, oxygen; NPK; calcium, magnesium, sulfur; iron, boron, manganese, copper, rheology, phase, chlorine, nickel, and different crops for nutrients The demand is also different, so there is a compound fertilizer, compound fertilizer, soil testing formula fertilizer, in order to achieve balanced nutrient absorption of crops. However, long-term production practices have found that the absorption rate of nutrients by different crops is different and non-linear. Therefore, controlled release fertilizers, mainly sulfur-coated and wax-coated technologies, have been invented, but the utilization rate of instant fertilizers has not been solved.

Applying the slow-release organic fertilizer for flower according to the first embodiment of the present invention to fertilize the first area (experimental area) of Baochao nursery base, planting camellia, smiling, and kaffir lime in the nursery, and still using NPK instant fertilizer in other areas for routine operation, Example 1 The flower is slowly buried in the ground with a slow release organic fertilizer of 20 kg/mu, and is watered. There is no top dressing in the whole growth period, and only the sensation is added. Compared with other regions, the nursery increased by 15% and the cost was saved by 20%.

It can be seen that traditional flower fertilizer (NPK instant fertilizer) is very wasteful due to its low speed utilization rate; it also causes burnt roots to affect flower yield, and it requires repeated repeated application of fertilizer and waste of manure and fertilizer. The slow-release organic fertilizer for flower according to the invention is synergistically reacted by various components, adsorbed and decomposed by lignin and diatomaceous earth, and the total nutrients required for flower growth are uniformly and slowly released within 120 days. To make flowers healthy, long-term, and vigorous. Good results were obtained by experiments with Tianjin Dongli, Baodi Nursery Base and Fujian Yongzhou Flower Base. In addition, the use of the slow-release organic fertilizer for flower according to the first embodiment of the present invention is welcomed by the market because of the long viewing period, bright color and easy management of the single plant flower, and the market price of the same variety is increased by 10-20%.

The detailed description of the above-mentioned reference embodiment of the present invention for the sustained release organic fertilizer for flower and the preparation method thereof are illustrative and not limiting, and several embodiments may be enumerated according to the limited scope, and thus Variations and modifications of the general inventive concept are intended to be within the scope of the invention.
