Problems solved by technology

Although foliar spraying has a certain effect, the absorption capacity of the leaves is limited, and the amount of absorption cannot meet the requirements of fruit trees, especially if there is rainfall after spraying, the spraying effect will be lost
Due to the high cost and high price of chelated calcium and iron fertilizers, it is difficult to popularize and apply them in production due to the large demand for soil application

Embodiment 1

[0040] The special organic-inorganic compound fertilizer for apples used as base fertilizer, the preparation method is as follows:

[0041] In parts by weight, 68 parts of xylitol residue, 15 parts of peat, 10 parts of calcium-magnesium phosphate fertilizer, 5 parts of ferrous sulfate, and 2 parts of microbial fermentation agent are fully mixed and uniform. Adjust the moisture content of the mixture to be 63%, C / N to be 30, and pH to be 7.5. Pile the mixture into a trapezoidal pile with a height of 1.5 meters, punch holes from the top down, 10 holes per square meter, cover with a plastic film, and carry out aerobic fermentation. When the temperature of the heap rises above 50°C, start timing, and ferment for 6 days. Turn over the pile, and ferment for another 4 days when the pile temperature rises above 50°C. Dry the moisture content of the above-mentioned fermented organic fertilizer to 35%. Take 60 parts of fermented organic fertilizer, 8 parts of urea, 22 parts of diammo...

Embodiment 2

[0043] The special organic-inorganic compound fertilizer for apples used as base fertilizer, the preparation method is as follows:

[0044]In parts by weight, 60 parts of xylitol residue, 18 parts of peat, 13 parts of calcium magnesium phosphate fertilizer, 3 parts of ferrous sulfate, and 1 part of microbial fermentation agent are fully mixed and evenly distributed. Adjust the moisture content of the mixture to be 65%, C / N to be 25, and pH to be 7.2. Pile the mixture into a trapezoidal pile with a height of 1.8 meters, punch holes from the top down, with 14 holes per square meter, cover with a plastic film, and carry out aerobic fermentation. When the temperature of the heap rises above 50°C, start timing, and ferment for 5 days. Turn over the pile, and ferment for another 5 days when the pile temperature rises above 50°C. Dry the moisture content of the fermented organic fertilizer to 30%. Take 60 parts of fermented organic fertilizer, 10 parts of urea, 18 parts of diammon...

Embodiment 3

[0046] The preparation steps and method of the apple-specific organic-inorganic compound fertilizer used as topdressing are the same as in Example 1, and its organic fertilizer fermentation raw materials are 65 parts of xylitol residue, 10 parts of peat, 15 parts of calcium magnesium phosphate fertilizer, and 8 parts of ferrous sulfate , 2 parts of microbial fermentation agent. After the fermentation, take 50 parts of fermented organic fertilizer, 23 parts of urea, and 27 parts of potassium sulfate. All raw materials were mixed uniformly, and prepared according to the method of Example 1.

Abstract

The invention relates to a special apple organic-inorganic compound fertilizer containing active calcium and iron nutritions and a preparation method thereof. The special apple organic-inorganic compound fertilizer containing active calcium and iron nutritions comprises the following raw materials: 35-65 portions of ferment organic fertilizers, 5-30 portions of urea, 0-25 portions of diammonium phosphate and 5-35 portions of potassium sulphate, wherein the ferment organic fertilizers are prepared by using 55-75 portions of xylitol residues, 10-20 portions of grass peat, 8-16 portions of calcium-magnesia phosphate fertolizers and 2-8 portions of ferrous sulfate as raw materials, adding 1-2 portions of microbial fermentation fungus agents and 1-2 portions of EM compound fungus agents to carry out fermentation and air-drying the mixture to reach the water content of 25-35wt%. The special apple organic-inorganic compound fertilizer containing active calcium and iron nutritions provides sufficient calcium and iron nutritions for apple growth, has reasonable nutrient ratio and improves the apple quality and the apple yield.

Description

technical field [0001] The invention relates to a special organic-inorganic compound fertilizer for apples containing active calcium and iron nutrition and a preparation method thereof, belonging to the technical field of fertilizer production. Background technique [0002] Apple is one of the four major fruits in the world, and it is a nutritious and popular fruit. Restricted by climatic factors, in my country, apple tree cultivation is mainly concentrated in northern regions such as Shandong, Henan, Hebei, Liaoning, and Shaanxi. The soil in these areas is mostly neutral or slightly alkaline. Due to the high pH value, the iron nutrition in the soil mainly exists in the form of iron hydroxide precipitation, which is not suitable for crops to absorb; the calcium nutrition in the soil exists as calcium carbonate, which loses its effectiveness for crops. At present, apples in my country suffer from bitter pit due to calcium deficiency, and leaf yellowing due to iron deficienc...
