Tomato composite fertilizer and production method thereof

Abstract

The invention discloses a tomato composite fertilizer and a production method thereof. The composite fertilizer concretely comprises 25wt% or above of total nutrients (N+P2O5+K2O), 20wt% or above of organic matters, 2-15wt% of chitin, 5-10wt% of composite amino acids, 0.1-0.5wt% of middle elements, 0.03-0.1wt% of trace elements and 2-15wt% of pyrite ash, wherein the above weight percentages of above components are represented according to GB18877-2009 organic-inorganic compound fertilizer national standards). The tomato composite fertilizer is prepared through preprocessing, granulation and magnetization, can provide nitrogen, phosphorus and potassium needed by growth of tomatoes, is rich in organic matters, can improve nutrition imbalance caused by continuous plowing of soil due to magnetization treatment, effectively improves physical characteristics of the soil and promotes absorption of nutrients by crops, can obviously improve the yield per unit area, can effectively inhibit threadworms in fields, mitigates the threadworm generation degree and improves the economic benefit.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and in particular relates to an organic-inorganic compound fertilizer applied to tomatoes and a production method thereof. Background technique [0002] Tomatoes are annual herbaceous plants and belong to the solanaceous vegetables. Tomatoes are not too strict on the soil, but they are suitable for deep, well-drained, fertile soil rich in organic matter. The growth cycle of tomato is roughly divided into germination period, seedling period, flowering and fruit setting period and fruiting period. [0003] Tomatoes have high yields, require a large amount of fertilizer, and have strong fertilizer tolerance. Tomato growth and development not only require nitrogen, phosphorus, and potassium macronutrients, but also calcium, magnesium, and other medium and trace elements. Tomatoes require a large amount of potassium, calcium, and magnesium. It is generally believed that every 1000kg tomato needs nitr...

Problems solved by technology

With the development of the protected vegetable industry, the cultivation area of ​​tomato in protected areas is expanding continuously, and the production benefits are becoming more and more significant. However, due to the heavy cropping cultivation, the occurrence and damage of diseases and insect pests continue to increase, especially the harm of root-knot nematodes, which seriously affects the growth of tomato. Coupled with the influence of climate anomalies and other factors, some years have caused heavy losses to tomato production

[0004] At present, domestic researches on special fertilizers for tomatoes mainly focus on the field of inorganic fertilizers and organic-inorganic compound fertilizers, such as 201010543258.8 (a special fertilizer for tomato in protected areas and its fertilization method), 200910113437.5 (preparation and application of a special fertilizer for tomato). Application method), 201310018990.7 (a special fertilizer for producing organic selenium-enriched tomato and its preparation method), 201110426331.8 (special enhanced fertilizer for tomato), there is no use of certain organic fertilizers to suppress or prevent the harm of main root-knot nematodes, and there is no impact on fertilizers Magnetization treatment, therefore, has little effect on improving the soil quality in heavy cropped tomato plots
