Problems solved by technology

Corn production requires a large amount of fertilizer and high input costs, resulting in high yields and low efficiency in corn production, and increased production without increasing income; at the same time, in recent years, biogas construction has developed rapidly, which has produced good economic and social benefits, but biogas waste cannot be digested in time Utilization will also affect the normal operation and circulation of the biogas digester

Embodiment 1

[0012] A method for fertilizing corn, comprising the steps of:

[0013] Step 1: Select biogas slurry and biogas residue with normal gas production for 2 months;

[0014] Step 2: Seed soaking in biogas slurry: choose a sunny day to sun-dry the seeds, turn them over for 1 day, remove impurities, then put the sun-dried seeds into a woven bag, and leave a quarter of the space in the bag, tie it with one end of the rope Hold the mouth of the bag, and fix the other end to the discharge port of the biogas tank, so that the seeds are in the middle of the biogas slurry, soak for 10 hours, after soaking, wash the seeds with clean water, and then dry them for germination and sowing;

[0015] Step 3: Base fertilizer: 700kg of biogas residue per mu, 40kg of superphosphate, 25kg of potassium chloride and 25kg of ammonium chloride are used as base fertilizer, and at the same time, 3kg of 40% polyaspartic acid is mixed in, directly sprinkled on the field surface and immediately Plowing, dept...

example 2

[0018] A method for fertilizing corn, comprising the steps of:

[0019] Step 1: Select biogas slurry and biogas residue with normal gas production for 3 months;

[0020] Step 2: Seed soaking in biogas slurry: choose a sunny day to dry the seeds, turn them over for 2 days, remove impurities, then put the sun-dried seeds into a woven bag, and leave a quarter of the space in the bag, tie it with one end of the rope Hold the mouth of the bag, and fix the other end to the discharge port of the biogas tank, so that the seeds are in the middle of the biogas slurry, soak for 10 hours, after soaking, wash the seeds with clean water, and then dry them for germination and sowing;

[0021] Step 3: Base fertilizer: 700kg of biogas residue per mu, 40kg of superphosphate, 25kg of potassium chloride and 25kg of ammonium chloride are used as base fertilizer, and at the same time, 3kg of 40% polyaspartic acid is mixed in, directly sprinkled on the field surface and immediately Plowing, depth 9...

Abstract

The invention relates to a fertilizing method for corn, comprising the steps of selecting biogas slurry and biogas residue normally producing biogas for two months or more; soaking seed with the biogas slurry, wherein soaking is carried out for 10 hours; applying base fertilizers, wherein the biogas residue, calcium superphosphate, potassium chloride and ammonium chloride are applied as the base fertilizers, and sodium of polyaspartic acid is mixed into the base fertilizers, the fertilizers are directly spread to the field and the soil is ploughed immediately with the depth of 6-9cm; and applying additional fertilizer, wherein three fertilizing periods are needed, namely, jointing fertilizer, spike fertilizer and particle fertilizer; the period of jointing fertilizer is to spray mixed solution of the biogas slurry and sodium of polyaspartic acid to the leave surface in the first three days of jointing; the period of spike fertilizer is to additionally apply ammonium chloride ten days before spike outgrowth in the large bell mouth period of corn; and the period of particle fertilizer is to spray the biogas slurry on the leave surfaces one day before and after corn pollination.

Description

technical field [0001] The invention relates to a corn cultivation method, in particular to a corn fertilization method. Background technique [0002] Corn is an important food crop. In my country, its planting area is second only to rice and wheat, ranking third. However, compared with other grain production, corn production has higher input costs and lower output benefits. Corn production requires a large amount of fertilizer and high input costs, resulting in high yields and low efficiency in corn production, and increasing production without increasing income; at the same time, in recent years, biogas construction has developed rapidly, which has produced good economic and social benefits, but biogas waste cannot be digested in time Utilization will also affect the normal operation and circulation of the biogas digester. Biogas slurry and biogas residue not only have complete nutrients and fast fertilizer efficiency, but also are easy to absorb and have little residue, ...
