Abstract

The invention relates to a canna controlled release fertilizer and a preparing method thereof. The fertilizer is obtained by compounding various modified epoxy resin coated fertilizers, various thermoplastic resin envelopes, potassium chloride compound fertilizers, etc. The canna controlled release fertilizer is applied every year, has advantages of saving labor and power, improving the fertilizer availability ratio, satisfying the request of nitrogen, phosphorus and kalium for canna, equal fertilization, and good adsorption for canna.

Description

technical field [0001] The invention relates to a modified epoxy resin and thermoplastic resin-coated controlled-release fertilizer for cannas and a preparation method thereof, belonging to the technical field of slow / controlled-release fertilizers for flowers. Background technique [0002] Canna is named for its leaves resembling plantains, large flowers and bright colors. It has a long flowering period, is not afraid of extreme heat, is easy to cultivate, and has extensive management. It can be cultivated in large-area gardens or potted. It is also an excellent variety of cut flowers and scenery for flower baskets and bouquets. Canna can absorb a large amount of harmful gases such as sulfur dioxide, chlorine, and fluoride during the growth process, which has a great effect on absorbing dust and purifying the air. Cultivation nearby and in front of the windows of the building can not only change the environment, but also purify the air. [0003] Canna can grow normally be...
