Abstract

The invention relates to a long-acting high-nitrogen compound fertilizer which is prepared from the following components in parts by weight: 6-10 parts of furfural residue, 7-11 parts of fertilizer-grade calcium hydrogen phosphate, 4-8 parts of sodium selenite, 2-7 parts of gypsum powder, 4-9 parts of zinc sulfate, 6-10 parts of tobacco residue powder, 4-8 parts of yellow meal worm powder, 5-9 parts of diammonium phosphate, 2-7 parts of rice hull, 4-10 parts of diammonium phosphate, 10-20 parts of soybean straw carbon powder, 5-7 parts of copper sulfate, 4-8 parts of ammonium molybdate, 1-5 parts of bamboo shoot shell and 4-10 parts of carboxymethyl cellulose. The fertilizer can satisfy the plant nutrient demands; and the organic fertilizer is added to improve the soil structure and enhance the utilization ratio of the fertilizer.

Description

A kind of long-acting high-nitrogen compound fertilizer material

Technical field

The present invention relates to a kind of long-acting high-nitrogen compound fertilizer material.

Background technology

Nitrogenous fertilizer contains the chemical fertilizer of crop alimentary elemental nitrogen.Elemental nitrogen plays very important effect to plant growth, and it is amino acid whose integral part in plant materials, be the composition forming protein, is also the chlorophyllous integral part that plant carries out photosynthesis and plays a decisive role.Nitrogen can also help crop to divide to grow.Applied nitrogen can not only improve the output of agricultural-food, can also improve the quality of agricultural-food.Nitrogenous fertilizer is also the one in inorganic salt.In actual production, often can run into the situation that farm crop nitrogen nutrition is not enough or excessive, the general performance of nitrogen nutrition deficiency is: plant is short and small, thin and delicate; Leaf is the improper greens such as yellowish green, yellow orange, and radical leaves is dry withered gradually; Root system branches is few; Tillering of cereal crop significantly reduces, and even do not tiller, ear differentiation is poor, and branch is few, and fringe shape is little, and the remarkable early ageing of crop is also precocious, and output reduces.

Summary of the invention

For the deficiencies in the prior art, the technical problem to be solved in the present invention is, provides a kind of high-nitrogen compound fertilizer material, can meet plant nutrition demand, with the addition of fertilizer simultaneously, improve the structure of soil, improve the utilization ratio of fertilizer.

For solving the deficiencies in the prior art, technical scheme of the present invention is, a kind of long-acting high-nitrogen compound fertilizer material, and it is made up of following weight part:

Furfural dregs 6-10 part, fertilizer grade secondary calcium phosphate 7-11 part, Sodium Selenite 4-8 part, terra alba 2-7 part, zinc sulfate 4-9 part, the broken last 6-10 part of tobacco leaf residue, tenebrio molitor powder 4-8 part, diammonium phosphate 5-9 part, rice husk 2-7 part, diammonium phosphate 4-10 part, soybean stalk powdered carbon 10-20 part, copper sulfate 5-7 part, ammonium molybdate 4-8 part, bamboo shoot shell 1-5 part, carboxymethyl cellulose 4-10 part.

The invention has the beneficial effects as follows, fertilizer of the present invention can meet plant nutrition demand, with the addition of fertilizer simultaneously, improves the structure of soil, improves the utilization ratio of fertilizer.
