Problems solved by technology

[0004] Therefore, we should provide fertilizers according to the needs of kiwifruit. At present, many new types of fertilizers have emerged, including compound fertilizers, organic fertilizers, biological fertilizers, organic-inorganic compound fertilizers, bio-organic fertilizers, organic-inorganic biological fertilizers, slow-release fertilizers, and controlled-release fertilizers. etc. These fertilizers have their own advantages and characteristics. Among them, the utilization rate of compound fertilizers is very low, causing serious waste and pollution. Although organic fertilizers are good, they do not have enough nutrients. Fertilizers have a short fertilizer effect period, and the effects of various controlled-release or slow-release fertilizers do not meet the growth requirements of kiwifruit

Embodiment 1

[0036] First prepare chicken manure fermented fertilizer, prepare 110 tons of chicken manure, 40 tons of bran powder, 38 tons of flue-cured tobacco straw, 2 tons of EM raw dew, 2 tons of basalt powder, and 8 tons of tea shell powder, of which EM raw dew is from Tianyi Biotechnology of Jiangxi Province Develop the products produced by the company; then crush the chicken manure, deodorize, dry, and then crush the flue-cured tobacco stalks; then fully stir the chicken manure, bran powder and 600kgEM original dew, and then stack them for 30 days of anaerobic fermentation. During the period, turn the compost once every 3 days, keep the fermentation temperature not lower than 35°C and not higher than 65°C, turn the compost on the last day to let the temperature drop; when the temperature drops to 20-30°C, add 400kg of EM raw dew and crushed flue-cured tobacco Stir the stalks well, and then ferment them again for 7 days. During this period, turn them over once a day and keep the ferme...

Embodiment 2

[0045] First prepare 120 tons of chicken manure fermented fertilizer according to the method of embodiment 1.

[0046] Then prepare 8.5 tons of urea, 17 tons of calcium magnesium phosphate fertilizer, 1 ton of potassium sulfate, 4 tons of potassium chloride, 65 tons of chicken manure fermented fertilizer, 8 tons of wood charcoal powder, 2 tons of superphosphate, 1 ton of bentonite, and 1 ton of solid bacterial agent tons, 0.1 tons of boric acid.

[0047] First, each raw material is crushed separately, then urea, calcium magnesium phosphate fertilizer, potassium sulfate, potassium chloride, boric acid and wood carbon powder are fully mixed and stirred, then granulated, and then the granules are sieved, and the granules with a particle size of 2mm are taken, and the rest are returned Re-grind and granulate; then fully mix 0.8 tons of superphosphate and 0.4 tons of bentonite, add water to mix the slurry, and then evenly spray the slurry on the surface of the granulated particles,...

Embodiment 3

[0054] First prepare 120 tons of chicken manure fermented fertilizer according to the method of embodiment 1.

[0055] Then prepare 9 tons of urea, 18 tons of calcium magnesium phosphate fertilizer, 1 ton of potassium sulfate, 4.5 tons of potassium chloride, 70 tons of chicken manure fermented fertilizer, 9 tons of wood charcoal powder, 2.2 tons of superphosphate, 1.2 tons of bentonite, and 1 solid bacterial agent. tons, 0.1 tons of boric acid.

[0056] First, each raw material is crushed separately, then urea, calcium magnesium phosphate fertilizer, potassium sulfate, potassium chloride, boric acid and wood charcoal powder are fully mixed and stirred, then granulated, and then the granules are sieved to obtain granules with a particle size of 1.5-2.5mm , and return the rest to re-grind and granulate; then fully mix 0.88 tons of superphosphate and 0.48 tons of bentonite, add water to mix the slurry, then evenly spray the slurry on the surface of the granulated particles, and t...

Abstract

The invention provides a controlled-release and slow-release compound fertilizer specialized for kiwi fruit, and belongs to the technical field of fertilizers. The compound fertilizer comprises 8-9 parts of urea, 16-18 parts of calcium magnesium phosphate fertilizer, 1 part of potassium sulfate, 3.5-4.5 parts of potassium chloride, 60-70 parts of fermented chicken manure fertilizer, 7-9 parts of charcoal powder, 1.8-2.2 parts of calcium superphosphate, 0.8-1.2 parts of bentonite, 1 part of a solid inoculant, and 0.1 part of boric acid. The compound fertilizer provided by the invention has the beneficial effects that urea, the calcium magnesium phosphate fertilizer, potassium sulfate and potassium chloride are prepared according to the proportions, the demand of the kiwi fruit plants on nitrogen, phosphorous and potassium is satisfied, and needed secondary elements such as calcium, magnesium, chlorine, sulfur and boron are guaranteed at the same time; besides, large amounts of organic substances are supplied to the kiwi fruit by large amounts of the fermented chicken manure fertilizer; and moreover, needed trace elements such as ferric, copper, sodium, zinc, cobalt and the like are contained in the compound fertilizer, so the elements necessary for the kiwi fruit are basically completed.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a compound-controlled slow-release fertilizer specially formulated for kiwifruit according to the nutrient demand characteristics of kiwifruit, which adopts coating controlled release, adsorption slow release and biological slow release to achieve comprehensive slow release effect. Background technique [0002] Kiwi fruit is a kind of vine fruit. Its fruit is rich in nutrition. In addition to total sugar, it also contains 12 kinds of amino acids, rich in protein and minerals such as calcium, phosphorus, potassium and iron. It is one of the most nutritious fruits. Because kiwi fruit is comprehensive and rich in nutrition and contains some important substances that are indispensable to the human body, it plays an important role in maintaining human health, preventing and curing diseases. Eating more kiwi can prevent senile osteoporosis; inhibit the deposition of cholesterol on the inner wall of the ...
