Special fertilizer for beer barley

Abstract

The invention provides a special fertilizer for beer barley. The special fertilizer is prepared from nitrogen, phosphorus and potassium (N:P2O5:K2O) in a ratio of 1-1.8:1.3-2.4:1.1-2.6, wherein for four types of soil, namely black earth, dark brown earth, meadow soil and albic soil, where the barley is planted, the proper ratios of nitrogen to phosphorus to potassium(N:P2O5:K2O) for fertilization are 1.0:1.0-2.0: 1.0-2.0, 1.0:1.2-1.5: 1.2-1.5, 1.0:1.5-2.0: 1.5-2.0, and 1.0:1.0-1.2: 1.0-1.2 respectively. The special fertilizer produced by the formula can obviously increase the yield of beer barley and improve product quality and is widely used as the special fertilizer for the beer barley.

Description

Technical field: [0001] The invention relates to chemical fertilizers, in particular special fertilizers for malting barley. Background technique: [0002] The key indicators of malting barley quality are protein content and 1000-kernel weight. The 1000-kernel weight of high-quality barley should be ≥40g; the protein content should be 9%-12%. In the optimal range, the nutritional index α-amino nitrogen is directly proportional to the protein content, which makes the beer have good flavor and palatability, and high nutritional value. Fertilization directly affects the quality of malting barley, and the amount of nitrogen fertilizer is positively correlated with protein content. Beer production in Heilongjiang Province has a history of 100 years, but due to the quality of beer wheat, the self-sufficiency rate of raw materials in beer production currently accounts for only 20%.

Problems solved by technology

Beer production in Heilongjiang Province has a history of 100 years, but due to the quality of beer wheat, the self-sufficiency rate of raw materials for beer production currently accounts for only 20%. A special fertilizer formula based on the nutrient status of different soil types and the law of fertilizer supply is proposed to solve the problem of beer wheat in Heilongjiang Province. Quality problems have become a major problem that needs to be solved urgently
