Embodiment 1

[0020] (1) Potted flower preparation: A new self-fertilizing miniature Chinese rose variety "Rosa chinensis minima'Qinhuai Xiannü' was selected, and the seedlings were raised by cuttings in the first ten days of July 2011. After 25 days, they were transplanted into pots (the pot diameter is 12cm), 5 plants are planted in each pot, and the substrate is prepared from peat and perlite (volume ratio 9:1). Afterwards, normal water management is used, and compound fertilizer is used after 10 days of transplanting;

[0021] (2) Compound fertilizer preparation: the composition of the four components of the compound fertilizer is as follows

[0022] A. According to the amount of compound fertilizer dissolved in 10kg water, the mother liquor of 1Kg of A component is prepared, and the amount of various compounds is: calcium nitrate tetrahydrate 10g, ammonium nitrate 1.1g, edetate disodium iron 0.1g;

[0023] B. be mixed with the mother liquor of 1Kg of B component by the consumption of ...

Embodiment 3

[0036] (1) Potted flower preparation: A new self-fertilizing miniature rose variety “Qinhuai Fairy” (Rosa chinensis minima ‘Qinhuai Xiannü’) was selected, and the overwintering potted flowers were pruned uniformly in early February 2011 to remove dead branches and leaves. The overwintering potted flowers of "Qinhuai Fairy" are planted with 4 cutting seedlings per pot. The diameter of the flowerpot is 12cm, and the substrate is made of peat and perlite (volume ratio 9:1). The potted flowers are placed in a plastic greenhouse, and the normal water management is carried out after the potted flowers start to grow, and compound fertilizers are started to be used;

Abstract

The invention discloses a soilless culture composite fertilizer for potted rosa chinensis minima. The soilless culture composite fertilizer comprises the following four components: (1) component A which comprises three compounds, i.e., calcium nitrate terahydrate, ammonium nitrate and disodium iron ethylenediaminetetraacetate; (2) component B which comprises three compounds, i.e., potassium nitrate, potassium dihydrogen phosphate and magnesium sulfate heptahydrate; (3) component C which comprises one compound, i.e., potassium metasilicate; and (4) component D which comprises five compounds, i.e., manganese sulfate terahydrate, zinc sulphate heptahydrate, boric acid, copper sulphate pentahydrate and sodium molybdate dihydrate. When the soilless culture composite fertilizer provided by the invention is used for soilless culture of potted rosa chinensis minima, growth and development of rosa chinensis minima are normal, the symptom of nutritional deficiency or poisoning of nutrient elements does not occur, the potted rosa chinensis minima is plump and balanced and has a high ornamental value, the incidence rate of powdery mildew of the potted rosa chinensis minima is decreased by 22 to 37% compared with that of potted rosa chinensis minima cultivated with soil, and the potted rosa chinensis minima is clean and sanitary and is suitable for being enjoyed in a house. The composite fertilizer is easy to absorb and use, can mitigate the harm of powdery mildew, substantially meets demands of growth and development of rosa chinensis minima and has a practical application value in production practice of soilless culture of the potted rosa chinensis minima.

Description

technical field [0001] The invention relates to a fertilizer for plant cultivation, in particular to a compound fertilizer for soilless cultivation of mini rose potted flowers. Background technique [0002] Miniature rose (Rosa chinensis minima) is a low flowering shrub of Rosaceae (Rosaceae) and is a type of modern rose. Ornamental cultivation. Miniature potted roses are often used in major festival markets such as Mother's Day and Valentine's Day. They are good products for festival consumption and gifts for relatives and friends. Potted flower production has developed into an important flower industry abroad and is a typical high-efficiency facility agriculture. [0003] Soilless cultivation of plants refers to a cultivation method that uses peat as a substrate instead of natural soil. It is the main production technology for large-scale facility cultivation of potted flowers today. It has the characteristics of saving fertilizer and labor, high yield and high quality, a...
