Abstract

The present invention discloses a fertilizer for resisting saline alkali and strengthening rice seedlings. The fertilizer is prepared by mixing an organic fertilizer, an inorganic fertilizer, trace elements, right quantity of regulating acid agent and right quantity of disinfectant, wherein the organic fertilizer is prepared by digesting and fermenting straw stalks and grass peat, and account for 15 to 25% of the fertilizer by weight; the inorganic fertilizer comprises 20 to 25% of ammonium sulfate, 15 to 25% of calcium phosphate monobasic, 10 to 15% of potassium sulfate or potassium chloride and 0.5 to 1% of active Zn, Si fertilizer and B, Ca, Mo, Mg, Fe, Mn, etc.; the weight of the regulating acid agent accounts for 20% of the fertilizer and is prepared by making furfural and rice hulls adsorb sulphuric acid by carbonization and adding 10 to 15% of land plaster; the disinfectant belongs to a hymexazol mixture or a topsin methyl-thiram mixture and accounts for 0.02 to 0.2% of the fertilizer. The components are prepared into a fertilizer for resisting saline alkali and strengthening rice seedlings without pollution by packaging. The product has the functions of increasing fertilizer effect, regulating acidity and resisting diseases and strengthening seedlings, and has obvious application effects on the culture of seedlings in the salinized land; the product enables the seedlings of paddy rice to have long, many and heavy roots, thick stems and tall, straight and elastic stem leaves, and enables paddy rice to have good seedling quality; moreover, the product can eliminate the agglomerate of the soil, improve salinization and recover the land capability.

Description

Anti salt and alkali paddy rice seedling strengthening fertilizer

Technical field

It is special-purpose fertile to the present invention relates to a kind of rice in saline-alkali field.

Background technology

In recent years, because the large scale application of dry seedling bed of rice thin planting cultivation technique, at present, the fertile kind of the raising rice seedlings of selling on the market is a lot, but from result of use, also fundamentally do not solve paddy seedbed damping-off, diseases such as bacterial wilt, especially seedbed, paddy rice producing region, saline and alkaline soil sickness rate is higher, contains the higher multiple salt of concentration in the alkaline land soil, its toxicity maximum be Su Da, content surpasses 0.005% and promptly produces murder by poisoning, formed alkaline soil solution solubility salt is many, and soil compaction hinders paddy rice to absorb moisture content, so that physiology lack of water, so this class area, Chang Yinyu does not go out strong sprout, disease occurs and a large amount of dead seedling, causes being short of seedling inserting not Shang seedling and missing farming season.

Summary of the invention

The object of the present invention is to provide a kind of anti salt and alkali paddy rice seedling strengthening fertilizer, be used for using on the salt affected soil, can eliminate and harden, improve saline and alkalinely, recover soil fertility, and have getting fat, acid adjustment, disease-resistant, the function of educating strong rice shoot.

The concrete technical scheme of the present invention is:

Anti salt and alkali paddy rice seedling strengthening fertilizer of the present invention is mixed by fertilizer, inorganic fertilizer, acidity regulator and sterilizing agent and forms.

Main raw material is: fertilizer is become thoroughly decomposed to ferment by the straw and the peat composed of rotten mosses and forms, and weight accounts for 15～25%;

Inorganic fertilizer comprises ammonium sulfate 20～25%, calcium superphosphate 15～25%, and vitriolate of tartar or Repone K 10～15%, trace element accounts for 0.5～1% among active Zn, Si fertilizer and B, Ca, Mo, Mg, Fe, the Mn etc.;

Acidity regulator weight accounts for 20%, by furfural and rice husk carbonization absorption sulfuric acid and to add 10～15% terra alba formulated;

Sterilizing agent accounts for 0.02～0.2% for disliking mould spirit or first good fortune mixture weight.

Compounding method

Check the weight after mixing evenly through the fermentation of becoming thoroughly decomposed with the inorganic fertilizer thorough mixing fertilizer (straw, the peat composed of rotten mosses) and be packaged as the A bag; With furfural and rice husk carbonization absorption sulfuric acid, and add acidity, desalination and the seedbed organic matter that 10～15% terra alba increases preparation, checking the weight is packaged as the B bag; Dislike mould spirit or first good fortune mixture 0.02～0.2% and carrier (potter's clay etc.) and be packaged as the C bag through checking the weight after evenly puddling; The ABC three pouch unifications packing bag of packing into is become finished product.

The invention has the advantages that:

1, adopt raw materials such as the strong furfural of adsorptivity, rice husk, adsorb the vitriol oil to greatest extent, make seedling strengthening fertilizer acidity showed increased, effectively in and the alkalescence of the nursery soil aqueous solution, generated nontoxic Yan Heshui, be convenient to rice seedling and normally absorb water.

2, increase peat composed of rotten mosses bio-organic fertilizer composition.The peat composed of rotten mosses is the good organic fertilizer of improvement alkaline soil, ratio of desalinization can reach 60%, and bio-fertilizer can increase the soil microorganisms total amount, can suppress sickle-like bacteria and reduce the disease generation, disease resistance, bio-fertilizer can promote root growth, strengthens the absorption of root system vigor and nutrient, improves the resistance of rice seedling, increase soil organic matter content, the structure of improving the soil, for comprehensively fertile, the time is long.

3, utilize terra alba to carry out chemical modifying, the gypsum organism mixes the ratio of desalinization height, and can reduce pH value.

4, this product has getting fat, acid adjustment, disease-resistant and strong sprout function, and the saltings effect of growing seedlings is remarkable, and the rice seedling root is long, root is many, root is heavy, stem is thick, and cauline leaf is tall and straight, flexible, and rice seedling quality is good.

With this product paddy rice is tested, and compared with like product;

Test method: use anti salt and alkali paddy rice seedling strengthening fertilizer of the present invention, 15 kilograms of per 40 square metres of average fertilisings;

The result shows, average many 0.5 of the number of sheets than contrast, and the wide many 0.07cm of leaf, the thick many 0.06cm of stem are tillered many 0.51, on average many 1.5 of radicals, the thick average many 0.6mm of stem, the heavy 4.1g of hundred strain fresh weights, dry weight 0.9g; The performance root is dark, seedling strong, has tangible getting fat, acid adjustment, disease-resistant, effect in strong sprout, has solved the technical barrier of the strong seedling of rice in saline-alkali field.
