CN103145480A - Compound fertilizer suitable for lettuce planting in high fertility area - Google Patents

Abstract

The invention provides a compound fertilizer suitable for lettuce planting in high fertility area. The compound fertilizer comprises nitrogen, phosphorus and potassium by weight content of 14-8-12, and accounting for 34%; and the compound fertilizer contains 0.7% of trace elements Mn, Mo and Cu. The above components are crushed, mixed, granulated, dried, cooled and sieved to obtain the compound fertilizer suitable for lettuce planting in high fertility area. The invention optimizes formulation of compound fertilizer components to maximize compound fertilizer efficiency; and the compound fertilizer is especially suitable for the soil in mountainous area of southern Anhui, and has great application prospect.

Description

A kind of composite fertilizer that is applicable to the regional lettuce planting of high fertility

Technical field

The present invention relates to a kind of composite fertilizer, be specifically related to a kind of composite fertilizer that is applicable to the regional lettuce planting of high fertility.

Background technology

Composite fertilizer has that nutrient content is high, minor component is few and the advantage such as physical behavior is good, for balance fertilizing, improves utilization rate of fertilizer, promotes the stable high yield of crop that very important effect is arranged, and is the important substance basis of improving crop yield.But it also has some shortcomings, and such as its nutrients ratio is always fixing, and different soils, required nutritive element kind, quantity and the ratio of Different Crop are various.Be directed to unique landforms and the soil characteristic of Wannan mountainous area, if only do not use Common compound fertilizer for edatope, not only can affect the output of farm crop, also can affect the agricultural-food mouthfeel.

Summary of the invention

For above the deficiencies in the prior art, the invention provides a kind of composite fertilizer that is applicable to the regional lettuce planting of high fertility.

The present invention is achieved by the following technical solutions:

A kind of composite fertilizer that is applicable to high fertility area lettuce planting, in described composite fertilizer, nitrogen, phosphorus, potassium mass content are 14-8-12, and the mass content total amount of nitrogen, phosphorus, potassium is 34%;

Contain micro-Mn, Mo and Cu in composite fertilizer, content is 0.7%;

Above-mentioned each component raw material is pulverized, and granulation after mixing, then drying, cooling, screening namely obtain being applicable to the composite fertilizer of high fertility area lettuce planting.

Beneficial effect of the present invention is: by the optimization to composite fertilizer's component preparation, reach the maximization of composite fertilizer's fertilizer efficiency, be specially adapted to the soil of Wannan mountainous area, has larger application prospect, not only can increase the output of farm crop, also can reach the purpose that improves the agricultural-food mouthfeel, make agricultural-food more adapt to social demand, more meet people's needs.

Embodiment
