Embodiment 1

[0014] This embodiment provides a special seed fertilizer formula and production process containing double micro-ingredients for corn, specifically including the following:

[0015] 1. The basic requirements for the dosage of special seed fertilizer formula for corn: the dosage of seed fertilizer is 300-450 kg / ha.

[0016] 1-1.5 kg / ha of pure zinc applied to the soil by this fertilizer, 3-5 kg / ha of biological fertilizer (200 million live bacteria / g), pure nitrogen in the seed fertilizer accounts for 30%-40% of the total nitrogen (60-75 kg / ha); pure phosphorus in seed fertilizer (P 2 o 5 ) accounts for 100% of the total phosphorus (45-60 kg / ha), pure potassium (K 2 O) accounts for 70% of the total potassium (50-70 kg / ha), and the remaining nitrogen and potassium fertilizers are provided by topdressing.

[0017] 2. Requirements for fertilizer formulations in special seed fertilizer formula for corn: urea (containing N: 46%), zinc-containing ammonium sulfate (containing N18%,...

Embodiment 2

[0026] The difference between this embodiment and Example 1 is that the special seed fertilizer for corn consists of urea 140 kg / ton, zinc-containing ammonium sulfate 122 kg / ton, monoammonium phosphate 186 kg / ton, diammonium phosphate 186 kg / ton, chlorine Potassium chloride 244 kg / ton and biological fertilizer 122 kg / ton are mixed, wherein the zinc-containing ammonium sulfate is made of 903 kg / ton of ammonium sulfate and 97 kg / ton of zinc sulfate, and the biological fertilizer is made of humic acid 380 kg / ton, 220 kg / ton of white clay, 70 kg / ton of bacterial agent, 330 kg / ton of livestock and poultry manure organic fertilizer, Bacillus subtilis: Bacillus amyloliquefaciens=40%:60%.

Embodiment 3

[0028] The difference between this embodiment and Example 1 is that the special seed fertilizer for corn consists of 142 kg / ton of urea, 125 kg / ton of zinc-containing ammonium sulfate, 184 kg / ton of monoammonium phosphate, 184 kg / ton of diammonium phosphate, chlorine It is made by mixing 240 kg / ton of potassium chloride and 125 kg / ton of biological fertilizer, wherein: the zinc-containing ammonium sulfate is made of 900 kg / ton of ammonium sulfate and 100 kg / ton of zinc sulfate, and the biological fertilizer is made of humic acid 390 kg / ton, 210 kg / ton of white clay, 65 kg / ton of bacterial agent, 335 kg / ton of livestock and poultry manure organic fertilizer, Bacillus subtilis: Bacillus amyloliquefaciens=60%:40%.

Abstract

The invention discloses a special seed fertilizer for corn containing double micro-components. ton, diammonium phosphate 180-190 kg / ton, potassium chloride 240-250 kg / ton, and biological fertilizer 120-130 kg / ton. The invention allocates nitrogen and potassium fertilizers according to the demand of nitrogen and potassium fertilizers in different growth stages of corn, reduces the nitrogen and potassium fertilizer content in the fertilizer formula, reduces the amount of nitrogen and potassium fertilizers in the previous seed fertilizer, and shifts suitable nitrogen and potassium fertilizers later. At the same time, adjust the fertilizer formulations of nitrogen fertilizer and phosphate fertilizer, increase the trace element zinc and biological fertilizers and other measures to improve the utilization efficiency of fertilizers, ensure that the corn population is not too prosperous during the vegetative growth period, improve the quality of the corn population, and ensure that the nutrient requirements of corn are satisfied in the early stage of growth. To meet the demand of corn, improve the root vitality of corn, and finally achieve the purpose of increasing yield and quality, improving fertilizer utilization rate, and reducing environmental pollution by improving corn seed setting rate and 100-grain weight.

Description

technical field [0001] The invention relates to a special seed fertilizer for corn. Background technique [0002] Corn is a major industrial raw material, feed and food crop. In 2014, the planting area of ​​corn in Heilongjiang Province has exceeded 100 million mu, and there is a trend of further development. Corn production is closely related to my country's food security issues. Fertilizers contribute about 40%-50% to corn production, and account for a large proportion of agricultural production materials input. The problem with the special corn fertilizer used in conventional production is that the ratio of nitrogen, phosphorus and potassium is unreasonable, and the proportion of nitrogen is too high. Generally, the nitrogen content of special corn fertilizer exceeds 20%. In addition, the amount of fertilizer used by farmers in the early stage Large, so that the nitrogen input of seed fertilizer in the early stage of corn production exceeds 60%, and the nitrogen amount o...
