Embodiment 1

[0048] Example 1 An environment-friendly special fertilizer for corn seed production, which is composed of furfural residue, soybean meal organic fertilizer, biological bacterial fertilizer, ZnSO 4 ·7H 2 O. Ammonium molybdate, polyvinyl alcohol, and water retaining agent are mixed according to air-dry weight percentage (kg / kg) 41:55:1.70:0.85:0.45:0.60:0.40.

[0049] The production method of this special fertilizer comprises the following steps:

[0050] (1) Weigh each component according to the formula.

[0051] ⑵Modification of furfural slag: Add 28~30kg of lime powder to every 1000kg of furfural slag to make the pH value of furfural slag 7.0~7.5 to obtain modified furfural slag.

[0052] (3) Modified furfural slag, soybean meal organic fertilizer, biological bacterial fertilizer, ZnSO 4 ·7H 2 O. Ammonium molybdate, polyvinyl alcohol, and water retaining agent are mixed according to the formula ratio, poured into the pre-dug pit, and 4.85~5.39kg of urea is added per...

Embodiment 2

[0053] Example 2 An environment-friendly special fertilizer for corn seed production, which is composed of furfural residue, soybean meal organic fertilizer, biological bacterial fertilizer, ZnSO 4 ·7H 2 O. Ammonium molybdate, polyvinyl alcohol, and water retaining agent are mixed according to air-dry weight percentage (kg / kg) 40.99:54.99:1.69:0.89:0.43:0.60:0.40.

[0054] The production method of this special fertilizer is the same as Example 1 .

Abstract

The invention relates to a special environment-friendly fertilizer for seed corn, which is formed by mixing a furfural residue, a bean pulp organic fertilizer, a biological bacterial fertilizer, ZnSO4*7H2O, ammonium molybdate, polyvinyl alcohol and a water-retention agent according to the air-dry weight percentage of (38-45):(52-59):(1.40-1.70):(0.55-0.89):(0.35-0.51):(0.40-0.68):(0.30-0.49). The fertilizer adopts a crop nutritive balance fertilization theory and a soil improvement fertility theory, integrates a long-acting function of the furfural residue, synergism of the biological bacterial fertilizer, water retention of the water-retention agent, a soil improvement function of polyvinyl alcohol, and nutritive functions of ZnSO4*7H2O and ammonium molybdate, achieves purposes of supplying crop nutrition, increasing the content of a soil organic matter, improving a water storage function of soil, and improving a soil structure, and solves the problems that the seed corn in Hexi Corridor of Gansu Province is large in planting area, an input of the organic fertilizer is insufficient, and the soil is hardened.

Description

technical field [0001] The invention relates to the field of seed production corn production, in particular to an environment-friendly special fertilizer for seed production corn. Background technique [0002] The Hexi Corridor of Gansu Province has established a corn seed production base of 100,000 hectares, with an annual output of 550,000 tons of corncobs. The four furfural factories in the Hexi Corridor of Gansu Province use corncobs to produce furfural, and the total amount of furfural residue discharged annually is 220,000 tons. Analysis of furfural slag contains 66~70% of organic matter, 49~64% of C, 0.50~0.61% of total N, 0.30~0.36% of total P, 1.10~1.18% of total K, and the contents of heavy metal elements Hg, Cd, Cr, and Pb are all less than GB8172 -87 stipulates the control content standard of agricultural organic waste. At present, furfural slag is used for returning to the field and incineration accounts for 30% of the total resources, and 70% of the furfural s...
