Abstract

The invention provides a compound fertilizer, which is characterized in that the compound fertilizer comprises the following components in percentage by weight: 20-70% of wormcast, 7-30% of rock phosphate, 10-40% of hempseed cakes, 5-15% of plant ash, 1-5% of potassium chloride, and 5-10% of ammonium nitrate. The compound fertilizer disclosed by the invention adopts the most commonly used materials as main raw materials, and fully considers the daily required nutrition of plants, through scientific compatibility, both the comprehensive nutrition and the good fertilizer effect are considered, and the ecological environment of soil can be obviously improved, thereby increasing the land capability and preventing soil hardness. In addition, because the compound fertilizer is prepared into an easily-applied spherical fertilizer, besides used in farmlands, the compound fertilizer also is an extremely convenient selection in gardening and family planting.

Description

A kind of composite fertilizer

Technical field

The present invention relates to field of agricultural production technologies, specifically refer to a kind of composite fertilizer.

Background technology

Fertilizer is rich in organism and multiple nutritional components, but the use fertilizer efficiency is poor, and shortterm effect is not obvious.And most of fertilizer adopts human and animal excreta, rubbish, crop residues as traditional fertilizer, is difficult to that the required element of soil is carried out specific aim and replenishes.In addition, in use also usually make us uncomfortable and the formation environmental pollution.And that inorganic fertilizer has fertilizer efficiency is fast, easy to use, with strong points, but has the single deficiency of nutrient, in practice, adopts the mode of composite fertilizer to solve the single problem of nutrient.But inorganic fertilizer causes soil and hardens, and the deficient problem of aging and long-term trace element does not effectively solve.The peasant adopts fertilizer and inorganic fertilizer to carry out combination according to practice, solves the deficiency of single kind fertilizer.In view of the foregoing, prepare a kind of environmental protection, easy to use, nutrient content is complete, and fertilizer efficiency is lasting, and is nuisanceless, pollution-free, and the composite fertilizer that increases soil fertility has been the development inexorable trend of fertilizer.

Summary of the invention

The objective of the invention is to overcome above-mentioned defective, provide a kind of nutritive ingredient comprehensive, fertilizer efficiency is good, can obviously improve ecological environment of soil, increases soil fertility, keeps soil from packing together, and improves a kind of composite fertilizer of crop yield.

Technical scheme of the present invention is as follows:

A kind of composite fertilizer is characterized in that containing wormcast, Rock Phosphate (72Min BPL), hempseed cake, plant ash, Repone K, ammonium nitrate, its weight percent are wormcast 20-70%, Rock Phosphate (72Min BPL) 7-30%, hempseed cake 10-40%, plant ash 5-15%, Repone K 1-5%, ammonium nitrate 5-10%.Said components is pulverized, mixed, and moulding is made spherical or granular particle.

The various trace elements of the present invention are comprehensive, and organic collocation is reasonable, and production cost is low.Wherein, wormcast is as a kind of material with crumb structure of nature Earthy Taste, and nutrient is more comprehensive.And be rich in humic acid, can provide the relatively abundanter required raw material of photosynthesis for plant.In addition, wormcast also contains and is rich in microorganism species, has excellent air permeability, and water-retentivity and nutrient preserving capability effectively improve soil mechanism and balance potential of hydrogen, imitates the disease-resistant crops ability that improves; The residue ash fertilizer of plant ash after as burning plants such as agricultural crop straw, faggots belongs to open-textured hot quick-acting inorganic fertilizers, calcic, potassium, phosphorus, nitrogen, iron, magnesium etc.Effectively replenish the deficiency of fertilizer; Rock Phosphate (72Min BPL) can increase phosphorus content in the soil, and hempseed cake is rich in organic matter and reaches 80%, has and disperses slow release effect preferably; Ammonium nitrate can increase nitrogen content; Repone K can replenish crop to the consumption of potassium.

If above-mentioned single being manured into soil, fertilizer efficiency is low and persistence is not strong, and they proportionally evenly are mixed and made into composite fertilizer, after being manured into soil, comprehensive fertilizer efficiency is strengthened, and has the advantage of inorganic fertilizer and fertilizer concurrently, be easy to crop and absorb, very strong water conservation is arranged, protect fertile effect.

The feasibility of scheme is that earthworm has begun to culture in a lot of areas, and wormcast is convenient to obtain; Rock Phosphate (72Min BPL) is the chemical fertilizers production raw material of using always, and quantity is many, and it is wide to distribute; The Semen Ricini cake is the byproduct of grain and oil enterprise, and is cheap; Plant ash is the product after the agricultural crop straw burning, and is with low cost, easily obtains; Repone K, ammonium nitrate have all become commodity, are easy to obtain.Composite fertilizer of the present invention is economic environmental protection not only, and cost is low, and fertilizer efficiency is long, and nutrient is many, also has effective Soil structure, physico-chemical property improved, and is conducive to the production of crop, improves crop yield, improves crop quality, is a kind of economic and practical composite fertilizer.

Embodiment 1

In steel basin, add each component by weight.Wormcast 50%, Rock Phosphate (72Min BPL) 10%, hempseed cake 15%, plant ash 15%, Repone K 5%, ammonium nitrate 5%, after fully stirring, through grinding, cross 60 mesh sieves, fine powder adds water, mixing, by the round hole sieve extruder grain of diameter 0.5cm, the round hole sieve screening is crossed in particle oven dry back, packs respectively by size to get final product.

Embodiment 2

In steel basin, add each component by weight.Wormcast 30%, Rock Phosphate (72Min BPL) 12%, hempseed cake 30%, plant ash 10%, Repone K 3%, ammonium nitrate 7%, said components is crossed 60 mesh sieves respectively through grinding, and after fully mixing, the fine powder water is made the peloid of the about 0.5cm of diameter as tackiness agent in coating pan.After the peloid oven dry, pack respectively by size and to get final product.

The present invention adopts the most frequently used material as main raw material, takes into full account the daily required nutrition of plant, and the science compatibility had both been considered comprehensive nutrition, and fertilizer efficiency is good, can obviously improve ecological environment of soil again, increases soil fertility, keeps soil from packing together.In addition, owing to make the spherical fertilizer of being convenient to use, except used in the farmland, gardening aspect and family planting also were a kind of selections very easily.

Claims

1. a composite fertilizer is characterized in that containing wormcast 20-70%, Rock Phosphate (72Min BPL) 7-30%, and hempseed cake 10-40%, plant ash 5-15%, Repone K 1-5%, ammonium nitrate 5-10%, described per-cent are weight percentage.
