Abstract

The invention relates to an algal polysaccharide alcohol functional compound fertilizer and a production method thereof, and belongs to the technical field of the compound fertilizers and the production method thereof. The algal polysaccharide alcohol functional compound fertilizer comprises the following raw materials in parts by weight: 0.5-3 parts of algal polysaccharide alcohol, 5-15 parts of humic acid, 5-10 parts of attapulgite, 69-85 parts of a nitrogen-phosphorus-potassium fertilizer, and 1-3 parts of a trace element carrier. The production method comprises the following steps of: (1) preparing raw materials; (2) preparing a sugar alcohol composite; (3) preparing a mixture; and (4) pelleting and drying. The algal polysaccharide alcohol functional compound fertilizer provided by the invention is characterized in that the production cost is effectively reduced and the production period is shortened; the algal polysaccharide alcohol functional compound fertilizer is capable of reducing the salt content in soil in the saline and alkaline land; the fertilizer release time is prolonged and the fertilizer utilization rate is increased; and simultaneously, necessary medium trace elements are added according to the growth demands of the crops; and as a result, the physiological disease problems of yellowing, deformity, root rot and the like of the crops in the saline and alkaline land due to nutrient deficiency are effectively solved.

Description

[0001] technical field [0002] The invention relates to a seaweed polysaccharide functional compound fertilizer and a production method thereof, belonging to the technical field of compound fertilizers and production methods thereof. Background technique [0003] The use of chemical fertilizers has made a great contribution to the increase of global grain production, but with the long-term and large-scale application of chemical fertilizers, the problem of soil salinization caused by it has gradually attracted people's attention. At present, there are mainly four types of saline-alkali land improvement technologies in China: physical improvement, water conservancy improvement, chemical improvement and biological improvement. The above methods have played a certain role in saline-alkali land improvement and agricultural production increase, but the special long-acting fertilizer for saline-alkali land improvement and long-acting slow-release function has not been reported ...
