Abstract
The invention discloses a production method for EDTA chelate efficient foliar fertilizer. According to the production method, the foliar fertilizer is obtained by subjecting disodium EDTA to a low-temperature rapid complexation with iron, copper, calcium, magnesium, zinc and manganese compounds respectively; concentrating and drying reaction products to obtain different EDTA chelates; and mixing the EDTA chelates with other components according to proportions. The foliar fertilizer is simple in production process and low in manufacture cost. A production process has no addition of foreign chloride ions or sulfate radicals, does not influence crop growth or cause soil hardening after use, is safe to use and has no side effect. The crop foliar fertilizer prepared by using the chelates obtained by the method can enter plant bodies rapidly through leaves, is fast in fertilizer efficiency, and has the effects of regulating nutrient supply, balancing metabolism nutrient demands and controlling release.
Description
Technical field
The invention belongs to crop foliage fertilizer technical field, specifically relate to a kind of production method of EDTA chelating salt foliage fertilizer.
Background technology
Foliage fertilizer sprays fertilizer as one, is generally applied to the surface of farm crop blade, and its nutritive element mainly enters into blade by the pore of blade, and then participates in the metabolism of crop.Therefore, the sticking power of foliage fertilizer on blade and the ability of infiltrating leaf tissue are fast the important indicators affecting foliage fertilizer fertilizer efficiency.The existing microelement foliage fertilizer ubiquity that widely uses water-soluble and poor adhesive force shortcoming, and blade absorbs slow, and effective nutritive element easily runs off, and affects the performance of fertilizer efficiency.Also there is foliage fertilizer by EDTA chelating salt and other element mixing manufacture fertilizer, but also there is complex process, the shortcoming that cost of manufacture is high; Simultaneously the EDTA chelating salt fertilizer produced of existing method is remaining a large amount of chlorion and sulfate radical, and crop uses for a long time, not only bad for leaf growth, and can cause soil compaction.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and is convenient to crop leaf absorption, and technique simple EDTA chelating salt foliage fertilizer production method.
For solving the problems of the technologies described above, the present invention includes following steps:
(1), EDETATE SODIUM is produced: produce EDETATE SODIUM by reacting with 0.5 to 1.5 part of (weight) sodium hydroxide after 6 to 8 parts of (weight) EDTA sequestrant dilute with waters.
(2), by EDETATE SODIUM at 100 to 120 temperature, carry out complex reaction with the compound of a certain amount of iron, copper, calcium, magnesium, zinc and manganese respectively, react after 40 to 50 minutes, concentrate drying obtains product.
Preferably in step 1, the weight part of EDTA sequestrant and sodium hydroxide is respectively 7 parts and 1 part, described EDTA sequestrant 5 parts of (weight) distilled water dilutings.
(3), by following composition by weight preparation foliage fertilizer:
Urea 42-45 part, potassium primary phosphate 40-50 part, EDTA chelating salt 13-15 part, borax 5-6 part; Wherein iron in EDTA chelating salt, copper, calcium, magnesium, zinc are identical with the chelating salt weight part of manganese.
In described step 2, metallic compound respectively: ferric oxide, ventilation breather, calcium carbonate, magnesium oxide, zinc oxide and manganous carbonate, and the amount (weight) that the EDETATE SODIUM produced with step 1 carries out the metallic compound of complex reaction is respectively ferric oxide 1.25 to 1.35 parts, ventilation breather 1.45 to 1.55 parts, 0.55 to 0.65 part, calcium carbonate, 0.95 to 1.05 part, magnesium oxide, 1.45 to 1.55 parts, zinc oxide and manganous carbonate 1.25 to 1.35 parts.
The present invention utilizes a certain amount of EDETATE SODIUM to carry out the quick complex reaction of low temperature with the compound of a certain amount of iron, copper, calcium, magnesium, zinc and manganese respectively, reactant obtains different EDTA chelating salt respectively after concentrated oven dry, the EDTA chelating salt obtained is mixed with other component in proportion and obtains foliage fertilizer again, production technique is simple, and cost of manufacture is low.Production process is added without Exogenous Chlorine ion and sulfate radical, even if product life-time service also can not affect plant growth and cause soil compaction, use safety, has no side effect.The chelating salt that present method makes makes foliage fertilizer, strong with attachment affinity in plant leaf Dispersion on surface film forming, is conducive to nutrient in the absorption of blade and the loss preventing nutritive ingredient; Nutritive element needed for plant utilizes chelating to form coordination valence molecular grouping, and the title complex formed is soluble in water, and can enter plant materials by blade rapidly, fertilizer efficiency is fast.Meanwhile, this sequestrant selectively can catch some metal ion and can discharge in right amount where necessary again in the cell of plant, has adjustment nutrition supply, balance metabolism nutrient demand and controlled-release function.
Below in conjunction with embodiment, the invention will be further described.
