Embodiment 1

[0030] Embodiment 1, the preparation of high-efficiency foliage calcium fertilizer 1

[0031] In parts by mass, 39.5 parts of calcium nitrate and 30 parts of water were dissolved to obtain fertilizer precursor A; 17.5 parts of sorbitol and 3 parts of glycine were dissolved in 20 parts of water to obtain fertilizer precursor B; A and B were mixed and stirred, React at 50-60 degrees Celsius for 8 hours to obtain fertilizer precursor C; add 2.5 parts of borax, 3 parts of olive oil alcohol, 5 parts of bratin lactone to C in sequence, and finally add 0.05 parts of sodium hydroxide to adjust the acidity and alkalinity. High-efficiency foliar calcium fertilizer can be obtained after all dissolved.

Embodiment 2

[0032] Embodiment 2, the preparation of high-efficiency foliage calcium fertilizer 2

[0033] In parts by mass, 33 parts of calcium chloride and 30 parts of water are dissolved to obtain fertilizer precursor A; 5 parts of sorbitol and 3 parts of glycine are dissolved in 20 parts of water to obtain fertilizer precursor B; A and B are mixed and stirred , react at 50-60 degrees Celsius for 5 hours to obtain fertilizer precursor C; like C, add 3 parts of borax, 3 parts of polysorbate, 5 parts of bradylidene lactone, and finally add about 0.05 parts of sodium hydroxide to adjust the acidity and alkalinity . High-efficiency foliar calcium fertilizer can be obtained after all dissolved.

Embodiment 3

[0034] Embodiment 3, the preparation of high-efficiency foliage calcium fertilizer 3

[0035] In parts by mass, 30 parts of calcium nitrate and 30 parts of water were dissolved to obtain fertilizer precursor A; 22 parts of sorbitol and 5 parts of glycine were dissolved in 15 parts of water to obtain fertilizer precursor B; A and B were mixed and stirred, React at 50-60 degrees Celsius for 6 hours to obtain fertilizer precursor C; like C, add 1.8 parts of borax, 3 parts of olive oil alcohol, 5 parts of 5-nitroguaiacol sodium, and finally add 0.05 parts of sodium hydroxide to adjust the acid alkaline. High-efficiency foliar calcium fertilizer can be obtained after all dissolved.

Abstract

The invention provides efficient calcium foliar fertilizer for treating apple bitter pit and a preparation method of the efficient calcium foliar fertilizer. The efficient calcium foliar fertilizer isprepared from raw materials in parts by weight as follows: 5-25 parts of oligosaccharide, 1-5 parts of amino acid, 30-45 parts of nutrition components, 2-8 parts of functional strengthening components and 35-50 parts of water. The efficient calcium foliar fertilizer has beneficial effects as follows: the calcium-boron content ratio of the selected nutrition components takes the calcium-boron content ratio (being 30-40:1) of apple leaves into full consideration, boron can promote conversion of organic acid and formation of carbohydrate in fruit trees while coordinating with absorption and transportation of calcium, and the current situation of increasing calcium content of fruits only by calcium supplement is changed; selected calcium transfer carriers such as oligosaccharide, amino acid and the like are low molecular weight organic matter capable of being directly absorbed by plants, and can promote growth of fruit trees synergistically; the selected functional strengthening components can prolong fruit attaching time of the foliar fertilizer on leaves and fruits of the fruit trees, improve penetrating quality of the foliar fertilizer and promote calcium absorption and can coordinate nutrient balance and promote fruit expansion and coloring.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a high-efficiency foliar calcium fertilizer for correcting apple bitter pit disease and a preparation method thereof. Background technique [0002] The calcium content in the soil of the main apple producing areas in northern my country is relatively rich, generally at 5%-8%, but the effective calcium content is only tens to hundreds of mg / kg, and the mobility of calcium in the plant is poor, and the phenomenon of calcium deficiency in production ( Bitter pox) is not uncommon. Foliar spraying of calcium fertilizer is an effective method to correct apple bitter pit. [0003] The foliar fertilizers currently on the market for correcting apple bitter pit can be roughly divided into simple inorganic calcium fertilizers (calcium nitrate, calcium chloride, etc.), mixed organic chelated calcium (EDTA calcium, amino acid calcium, sugar alcohol calcium). There are a wide variety of ca...
