Formula of special compound fertilizer for ryegrass

Abstract

The invention relates to a formula of a special compound fertilizer for ryegrass. The formula is researched and developed according to the biological characteristics and growth characteristics in northern area, aiming at solving the problems that ryegrass is hard to grow in poor soil and the seedlings easily die in the northern area. The formula is characterized in that a chemical fertilizer accounts for a large proportion in the formula; the formula mainly comprises urea, diammonium phosphate, potassium sulphate, and ammonium ferrous sulfate. The formula has the advantages that all components are easily dissolved in water and can supplement the nutrient for ryegrass after being applied to the land, and thus the ryegrass can quickly grow; 30 to 55g special compound fertilizer is applied per square meter for one to three times each year; all raw materials in the formula are common materials and easily purchased; the effect is obvious after application.
