Embodiment 1

[0027] Collect 100 liters of gulonic acid mother liquor (weight is 130-135 kilograms, wherein short-chain organic acids account for 60-70%), put in the pond, adjust pH to 7.2 with 25 kilograms of slaked lime, add urea 3kg, potassium dihydrogen phosphate 1.0kg, Zinc sulfate 0.2kg, air-dry at 35°C until the moisture content of the modifier is less than 20%, pass through a 20-mesh sieve, use a granulator to granulate, sub-package, and prepare finished products.

[0028] In the finished product obtained in this embodiment, 80 kilograms of calcium salts of short-chain organic acids (including calcium formate, calcium oxalate, calcium propionate, calcium butyrate, calcium guronate, etc.), 3 kilograms of urea, and 1 kilogram of potassium dihydrogen phosphate , 0.2 kg of zinc sulfate.

[0029] In the guaronic acid mother liquor of the present embodiment, by weight percentage, the main composition of short-chain organic acids is as follows: 20% guaronic acid, 40% formic acid, 10% oxali...

Abstract

The invention discloses a new manufacturing technique of antibiotic soil modifier to improve soil fertility and prevent pest, which comprises the following parts: 78-94.5% short-chain organic acid calcium salt, 2.5-5.0% aquacare, 1.0-2.0% potassium dihydrogen phosphate and 0.1-0.2% zinc sulfate. The pH value is adjusted to neutral through calcium salt (or alkaline), which is dried to form the product with fitful nourishing and microdose elements.

Description

technical field [0001] The invention relates to a new technology for the production of an antibiotic soil improver, that is, to produce a soil improver capable of improving soil fertility and preventing and controlling crop diseases and insect pests by using gulong acid mother liquor and a preparation method thereof. Background technique [0002] In recent years, due to the transition of farmland reclamation and the abuse of chemical fertilizers and pesticides, the soil has been seriously degraded, and various diseases and insect pests have come one after another. Crop production is suppressed, with lower yields and poorer taste. Most of the current prevention and control methods are to regenerate the soil in a large amount of land, which is effective but far from ideal, and it is costly and labor-intensive. In the exploration of new control measures, ecological control has received extensive attention, that is, through the application of specific organic matter to change t...
