Abstract
The invention relates to a compound fertilizer special for corn and a preparation method thereof, and belongs to the field of crop fertilizers. The compound fertilizer special for corn is prepared by silkworm excrement, vinasse, fulvic acid, fermented bean dregs, broomcorn, a peanut cake, a corn straw fermenting liquid, gelatin, urea, diammonium phosphate and potassium sulphate through a special method. Different components in the fertilizer are released according to a certain sequence, so that the demand for different elements in different growth stages of soybean is satisfied, and the growth rhythm of soybean is met. Therefore, yellow leaves in the initial growth stage can be avoided, and strain collapse in the mature stage can be avoided. Meanwhile, the yield and quality of corn are further effectively improved, so that the content of trace nutritional ingredients is higher so as to better meet the dietary standard of modern people.
Description
Technical field
The present invention relates to a kind of special compound fertilizer for corns and preparation method thereof, belong to farm crop fertilizer field.
Background technology
China is a large agricultural country, chemical fertilizer and agricultural chemicals are being brought into play very important effect in agricultural production process, along with the raising of people's living standard and health perception, people pay much attention to the security of agricultural-food, and demand nuisanceless, green food is increased year by year.Corn is China staple crops; It is a lot of that current corn is planted fertilizer type used, and corn fertilizer adopts NPK composite fertilizer, the especially Controlled Release Fertilizer that on market, can buy mostly.But the special controlled-release compound fertilizer of existing corn exists the growth demand of fertilizer release rate and corn, identical rate is low, thereby causes the problem yielding poorly, corn quality is low.
Summary of the invention

Beneficial effect
In special compound fertilizer for corns of the present invention, take organic composition as main, comprise the mineral manure that can discharge fast simultaneously; Not only contain a large amount of nitrogen, phosphorus, potassium, contain amino acid, enzyme, acid amides, beneficial organism bacterial classification simultaneously, abundant and comprehensive nutrition is provided can to the growth of soybean.Take silkworm excrement as carrier, can play the effect that makes fertilizer slow release, can play the effect of chessom simultaneously soil is played to improving effect; Silkworm excrement degradable, not only can not bring destruction to environment, and after degraded, can serve as the organic fertilizer of soybeans they grow.Adopt special preparation method to be prepared from, the heterogeneity in fertilizer discharged in a certain order, thus meet soybean at different growth phases the needs to different elements, the growth rhythm of compound soybean; Therefore there will not be yellow leaf phenomenon at early growth period, there will not be in the ripening stage phenomenon of falling strain; Also effectively improve the yield and quality of corn simultaneously, made the content of micro-nutrient composition of corn higher, dietary standards that more can compound modern.Raw material sources are extensive and cheap; Preparation method is simple.
Manure trial
Experimental field be located in the one peasant household's farmland covered by contract of Jiyang County, Shandong Province, 2.4 mu of areas, moisture soil, middle fertility, full field uniformity, irrigation and drainage are convenient, sunny.Experimental plot is on average divided into four (ABCD), and the area of every equates.Corn variety is Shandong list 6076, is corn-specific controlled-release fertilizer and special compound fertilizer for corns of the present invention for test fertilizer.Sowing on June 13rd, 2012, every mu of application rate 2-2.5 kilogram, density is every mu of 4200 strains; Accomplish line-spacing, seed level uniformity, it is straight that row is wanted, and shattering is even, and earthing is tight.Fertilising: field A, corn seeding mu is used 21 kilograms of 40% Controlled Release Fertilizers, disposable employed when sowing, notes separately 5-7 centimetres, seed and fertilizer, with unburned kind when sowing; Field B, C, D use respectively 18 kilograms of the prepared special compound fertilizer for corns of embodiments of the invention 1-3; When sowing, note separately 5-7 centimetres, seed and fertilizer, with unburned kind.Four experimental plots adopt identical way to manage to carry out chemical weed control, look into the daily administrations such as seedling is filled the gaps with seedlings, intertill and clean tillage, prevention and elimination of disease and pests.Withered loose when bract, seed hardening is shinny, and milk-line disappears, and when black layer appears in base portion, is full ripe stage, can gather in the crops.
Corn is surveyed and is produced result as following table:
| ? | Field A | Field B | Field C | Field D |
| Plant height | 285 | 293 | 293 | 292 |
| Fringe grain | 439 | 460 | 463 | 457 |
| Spike length | 16.1 | 17.3 | 17.4 | 17.1 |
| Lodging rate | 2.4 | 1.2% | 1.1 | 1.2 |
| Output kg/ mu | 603.2 | 624.3 | 625.9 | 631.2 |
By upper table, adopt the corn of corn composite fertilizer plantation of the present invention, its output is significantly improved, and lodging rate has obvious decline.
The corn that field B, C, D are produced carries out composition detection: crude protein content 13.3%, crude fat 3.3%, Methionin 0.33%, thick starch 69.1%, robust fibre 1.4%, 2.1 milligrams of iron, 24 milligrams of calcium.The corn producing compared with field A, the corn that adopts corn composite fertilizer of the present invention to plant, the content of its protein, robust fibre, iron, calcium, Methionin all obviously improves.
