Abstract

The invention discloses a drip irrigation special fertilizer specially used in the whole growth time of a cut flower rose. The drip irrigation special fertilizer comprises the following main components in part by weight: 442 to 466 parts of potassium nitrate, 115 to 149 parts of mono-ammonium phosphate, 170 to 230 parts of urea, 203 to 211 parts of magnesium sulfate heptahydrate, 0.1 to 0.3 part of boric acid, 3.6 to 5.6 parts of EDTA chelated iron, 0.4 to 0.7 part of EDTA chelated copper, 1.2 to 1.9 parts of EDTA chelated manganese, 0.01 to 0.03 part of EDTA sodium molybdate, and 0.4 to 0.7 part of EDTA chelated zinc. The drip irrigation special fertilizer is specially designed for a drip irrigation system, and can significantly improve the yield and the quality of the rose after being used by combining a law of the demand on various nutrients for the cut flower rose in the whole growth time. Besides, the drip irrigation special fertilizer can also improve the utilization ratio of the fertilizer, reduce the fertilizer input for farmers and directly reduce the production cost. At present, the country encourages the development of water-saving irrigation and fertilizer-reducing efficiency-increasing techniques, so the drip irrigation special fertilizer can have a more extensive market prospect.

Description

Technical field [0001] The invention relates to a special fertilizer for drip irrigation for agricultural production, in particular to a special fertilizer for drip irrigation suitable for the whole growth period of cut roses. Background technique [0002] Cut-flower roses are among the top four fresh cut flowers in the world, so the cultivation of cut-flower roses has become the focus of research in various countries around the world. In my country, most of the rose planting is relatively scattered, and the professional level of most growers is not high, especially the lack of professional knowledge in water and fertilizer. This leads to the high production cost, low yield, and poor quality of roses in the international market. Weak competitiveness and other issues. At the same time, foreign rose growers have applied the most advanced modern planting techniques to rose cultivation, such as: greenhouse environment automated control, drip irrigation technology, substrate hydroponi...
