Humic acid water-soluble fertilizer for tomato planting and preparation method thereof

Abstract

The invention provides a humic acid water-soluble fertilizer aqua for tomato planting and a preparation method thereof, and relates to the field of water-soluble fertilizers. The humic acid water-soluble fertilizer aqua comprises the following components in parts by weight: 15-20 parts of urea, 1-4 parts of calcium dihydrogen phosphate, 40-50 parts of modified expanded straw, 20-30 parts of humicacid, 20-30 parts of acrylamide, 2-5 parts of an EM microbial inoculum, 6-9 parts of pregelatinized starch, 3-6 parts of inorganic composite components, 10-15 parts of fatty alcohol polyoxyethylene ether, 0.01-0.05 part of an initiator, 1-3 parts of ammonium pentadecyl sulfonate, 1-3 parts of sodium lauroyl sarcosinate, 3-6 parts of a composite chelating agent, 1-2 parts of sodium tartrate, 3-7 parts of fulvic acid, 1-2 parts of sodium carboxymethyl cellulose and 500-800 parts of water. The humic acid water-soluble fertilizer aqua has a reasonable formula and multi-element nutrients and facilitates cultivation and growth and development of roots of crops. The usage amount is low, application is convenient, application cost is low, absorption of crops is fast, the utilization rate of nutrient components is extremely high, and quality and yield of tomatoes are improved.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a humic acid water-soluble fertilizer for tomato planting and a preparation method thereof. Background technique [0002] Tomato, namely tomato (scientific name: Lycopersicon esculentum Mill.), is an annual or perennial herbaceous plant of Tubularfloweres, Solanaceae, Tomato genus, with a body height of 0.6-2 meters. Easy to lodging, leaves pinnately compound or pinnately parted, peduncle 2-5 cm long, often 3-7 flowers, calyx radial, corolla radial, berries oblate or subglobose, fleshy and juicy, Seeds yellow, flowers and fruits in summer and autumn. Tomatoes are native to South America and are widely cultivated in northern and southern China. Tomato fruit is rich in nutrition and has a special flavor. Can be eaten raw, cooked, processed tomato paste, juice or whole fruit canned. [0003] In general, using drip irrigation for tomato watering can change the local microclimat...

AI Technical Summary

Problems solved by technology

At present, the problems existing in the process of tomato drip irrigation with water and fertilizer are that the water solubility of the fertilizer is not good, resulting in low fertilizer utilization rate, uneven fertilization, burning seedlings, root damage, and weak seedlings, etc., which eventually lead to a decrease in the quality and yield of tomatoes.

[0004] Patent CN201110426331.8 discloses a formula and production method of tomato-specific enhanced fertilizer, which is to mix and stir urea, ammonium bicarbonate, superphosphate, potassium nitrate, potassium chloride and additives according to a certain proportion, and use a special Produced by chemical fertilizer production equipment, although the fertilizer avoids single fertilization, the organic matter content in the fertilizer is small, resulting in poor water retention capacity of the soil, no drought resistance function, and unbalanced nutrition. It also contains ammonium bicarbonate and superphosphate, which is soluble in water. Calcium carbonate precipitation is easy to form after that, and it is easy to cause blockage of drip irrigation pipes
