Special compound fertilizer for peanuts

Abstract

The technical scheme of the invention relates to a special compound fertilizer for peanuts. The special compound fertilizer for peanuts comprises 3-10% of diatomite, 1-5% of carboxylic acid, 15-35% of urea, 1-3% of water-soluble fiber PVA (polyvinyl alcohol), 5-15% of calcium superphosphate, 1-5% of nitrogen-pyridine and the balance of pulverized straws. The diatomite has high adsorptivity, adsorbs urea and other available fertilizers, and implements slow-release of fertilizer efficiency; the carboxylic acid is beneficial to regulating the soil microenvironment and reducing the phenomenon of soil hardening; the urea is a fertilizer main component, and provides the sufficient nitrogen fertilizer for peanut growth; the water-soluble fiber PVA performs the functions of an adhesive, and is used for attaching the nitrogen fertilizer to the diatomite to enhance the adsorptivity of the diatomite, thereby being more beneficial to slow release and enhancing the fertilizer efficiency; the calcium superphosphate provides a phosphate fertilizer and a proper amount of calcium for the peanuts; the nitrogen-pyridine performs the function of nitrogen fixation, reduces the loss of the nitrogen fertilizer and enhances the fertilizer efficiency; and the pulverized straws belong to a base fertilizer, are beneficial to circular economy, and are also beneficial to reducing the consumption of the traditional fertilizer, so that the soil can be rehabilitated.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special compound fertilizer for peanuts. Background technique [0002] With the improvement of people's living standards, the demand for peanut market continues to expand, and the amount of peanut planting in Northeast China is increasing. The yield and product quality of peanuts are related to the direct economic benefits of the majority of farmers. How to apply fertilizer reasonably and what fertilizer to apply Achieving the greatest economic benefit from peanuts is one of the keys. Traditional chemical fertilizers, farmyard manures, organic fertilizers and other fertilizers cannot achieve the nutrients required for peanut growth, and either large application amounts or high comprehensive costs lead to low economic benefits for growers. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a special compound fertilizer for peanuts. Through the improvement of t...
