Problems solved by technology

However, the variety of chemical fertilizers currently on the market is relatively single, which cannot provide comprehensive nutrients for pitaya. Applying different fertilizers at the same time will cause soil compaction, loss of nutrients, low absorption rate, increased labor costs, pollution and waste.

Embodiment 1

[0032] A fertilizer formula for improving the growth quality of dragon fruit, mainly composed of the following raw materials and their concentrations: urea 11.18g / kg, potassium nitrate 11.4g / kg, potassium dihydrogen phosphate 1.66g / kg, calcium nitrate tetrahydrate 475.25g / kg , magnesium sulfate heptahydrate 2.28g / kg, boric acid 144.14mg / kg, chelated iron 117.5mg / kg, copper sulfate pentahydrate 9.36mg / kg, zinc sulfate heptahydrate 3.36mg / kg, manganese sulfate tetrahydrate 1.42mg / kg and ammonium heptamolybdate tetrahydrate 0.13mg / kg, the solvent is water.

Embodiment 2

[0034] With the above-mentioned embodiment 1, its difference is: also include seaweed bio-fertilizer, the mass concentration of seaweed bio-fertilizer in fertilizer is 500 g / kg. The seaweed bio-fertilizer is provided by the Key Laboratory of Ocean Engineering, School of Oceanography, Ningbo University. It is produced by combining the algae residue after extracting alginate and alginate with the Feton system degradation technology and the fermentation and degradation technology of alginic acid-degrading bacteria. Because the seaweed biological fertilizer used in the present invention contains natural active substances such as seaweed polysaccharide, auxin, betaine and indole acetic acid, it has the effect of improving crop growth and fruit quality. The seaweed biological fertilizer turns waste into treasure, is safe and pollution-free, has a simple application method, and is suitable for large-scale application.

Embodiment 3

[0036] A kind of preparation method of the fertilizer formula that improves dragon fruit growth quality, concrete steps are as follows:

[0037] (1) Dissolve urea, potassium nitrate, potassium dihydrogen phosphate, potassium dihydrogen phosphate, magnesium sulfate heptahydrate and calcium nitrate tetrahydrate in 1kg of tap water;

[0038] (2) Add chelated iron, boric acid, manganese sulfate tetrahydrate, zinc sulfate heptahydrate, copper sulfate pentahydrate, ammonium heptamolybdate tetrahydrate to the product of step (1);

[0039] (3) Fully dissolve and mix well to obtain the finished fertilizer, in which the concentration of each component in the finished fertilizer is urea 11.18g / kg, potassium nitrate 11.4g / kg, potassium dihydrogen phosphate 1.66g / kg, calcium nitrate tetrahydrate 475.25g / kg kg, magnesium sulfate heptahydrate 2.28g / kg, boric acid 144.14mg / kg, chelated iron 117.5mg / kg, copper sulfate pentahydrate 9.36mg / kg, zinc sulfate heptahydrate 3.36mg / kg, manganese sulfa...

Abstract

The invention discloses a fertilizer formula capable of improving the growth quality of dragon fruit and a preparation method and application thereof. The fertilizer formula is characterized in that the fertilizer formula is mainly prepared from the following raw materials with concentrations thereof: 11.18 g / kg of urea, 11.4 g / kg of potassium nitrate, 1.66 g / kg of monopotassium phosphate, 475.25 g / kg of tetrahydrated calcium nitrate, 2.28 g / kg of magnesium sulfate heptahydrate, 144.14 mg / kg of boric acid, 117.5 mg / kg of chelated iron, 9.36 mg / kg of copper sulfate pentahydrate, 3.36 mg / kg of heptahydrate, 1.42 mg / kg of manganese sulfate tetrahydrate and 0.13 mg / kg of ammonium heptamolybdate tetrahydrate, wherein the solvent is water, and the fertilizer formula can also comprise a seaweed bio-fertilizer. The fertilizer formula has the advantages that the flowering phase and fruit ripening time can be reduced through application as a leaf fertilizer of the dragon fruit, the blooming fruiting rate is improved, the fruit sugar accumulation is promoted, the fruit quality is optimized, and the volume, quality, sweetness and Vc content of the dragon fruit are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a fertilizer formula for improving the growth quality of dragon fruit and its preparation method and application. Background technique [0002] Dragon fruit is a tropical fruit, native to tropical desert regions of Central America such as Brazil and Mexico, and later introduced to Taiwan from Southeast Asia, and then introduced to Hainan Province and mainland China after being improved by Taiwan. It is rich in nutrition and has the functions of beauty, diet and health care, and is deeply loved by the people in the mainland. However, due to its late start in commercialization and large-scale planting, there are still many problems. Due to the long harvesting period of dragon fruit, chemical fertilizers need to be applied in different periods to meet its growth needs. However, the variety of chemical fertilizers currently on the market is relatively s...
