Abstract

The invention belongs to the technical field of biological fertilizers and in particular relates to an ecologically friendly wheat straw matrix compound fertilizer and a preparation method of the compound fertilizer. The preparation method of the compound fertilizer comprises the following steps: firstly pre-treating wheat straws by using an aqueous solution containing triethanolamine and fatty acid methyl ester ethoxylate, and then preparing a matrix; then composting and turning over to prepare fermented wheat straws; then, mixing with carbamide, diammonium phosphate, calcium peroxide and potassium sulphate according to a ratio in parts by weight, then pelleting to prepare the wheat straw matrix compound fertilizer. The preparation method of the compound fertilizer is short in fermentation time; the prepared wheat straw matrix compound fertilizer can supply nutritive elements needed for crops, is environmentally friendly and is capable of improving soil.

Description

technical field [0001] The invention belongs to the technical field of biological fertilizers, and in particular relates to an eco-friendly wheat straw matrix compound fertilizer and a preparation method thereof. Background technique [0002] my country can produce more than 600 million tons of crop straw every year, most of which have not been efficiently utilized, posing a major challenge to the sustainable development of modern agriculture. Wheat straw is an important agricultural resource, containing a large amount of organic matter, nutrients and various trace elements, of which nitrogen, phosphorus, potassium, calcium and sulfur account for 0.5%, 0.3%, 0.6% and 0.2% of the dry weight of wheat straw respectively and 0.1%, which can provide a variety of essential nutrients for crop growth. [0003] At present, people use a lot of chemical fertilizers in the process of planting crops, which leads to soil acidification and compaction, imbalance of nutrient elements, reduc...
