Problems solved by technology

But it also has some disadvantages, such as its nutrient ratio is always fixed, and the types, quantities and ratios of nutrient elements required by different soils and different crops are varied.
In view of the unique topography and soil characteristics of the mountainous area in southern Anhui, if ordinary compound fertilizers are only applied without targeting the soil environment, it will not only affect the yield of crops, but also affect the taste of agricultural products

Embodiment Construction

[0009] The invention provides a compound fertilizer suitable for planting lettuce in high-fertility areas, wherein the mass content of nitrogen, phosphorus and potassium is 14-8-12, and the total mass content of nitrogen, phosphorus and potassium is 34%. The compound fertilizer also contains trace elements Mn, Mo and Cu, the content is 0.7%.

[0010] The raw materials of the above-mentioned components are pulverized, mixed and granulated, and then dried, cooled and screened to obtain the compound fertilizer suitable for lettuce planting in high-fertility areas.

[0011] The present invention maximizes the fertilizer efficiency of the compound fertilizer by optimizing the formulation of the compound fertilizer components. It is especially suitable for the soil in the mountainous area of ​​southern Anhui, and has great application prospects. It will not only increase the yield of crops, but also achieve the purpose of improving the taste of agricultural products. Make agricultur...

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

technical field [0001] The invention relates to a compound fertilizer, in particular to a compound fertilizer suitable for lettuce planting in high-fertility areas. Background technique [0002] Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. It is an important material basis for increasing crop yield. But it also has some disadvantages, such as its nutrient ratio is always fixed, but the types, quantities and ratios of nutrient elements required by different soils and different crops are varied. In view of the unique topography and soil characteristics of the mountainous area in southern Anhui, if ordinary compound fertilizers are only applied without targeting the soil environment, it will not only affect the yield of crops, but also affect the taste of agricu...
