Problems solved by technology

[0002] At present, there are some difficult problems in the application of fertilizers, such as the low utilization rate of fertilizers, the pollution of the ecological environment caused by excessive application of chemical fertilizers, etc.; in addition, dissolved organic carbon is an active substance in soil or water ecosystems. The composition and form transformation of various microorganisms and various nutrients in soil or water play an important role, and at the same time have a profound impact on the biogeochemical cycle and the toxicity and migration of heavy metals in the surface ecosystem

Abstract

The invention provides a compound fertilizer for promoting increase production of leaf lettuce, which comprises the following component materials: 15-19 % of urea, 2-4 % of monoammonium phosphate, 4-6 % of potassium sulfate, 4-7 % of monopotassium phosphate and the like. When the fertilizer is applied, a contrast test between the nutrient fertilizer and the compound fertilizer commonly used in the gardening field is carried out, a planting area is set at random, each of fertilizers is applied for one time, and the same farmland management measurement is employed. According to the statistics, after the compound fertilizer is applied, the seed emergence rate can be achieved to 93 %; and by applying a nanometer additive, the absorption amplitude increase of a majority of elements to plants is increased by 16 %, the ratio of disease infection is reduced by 5 %, the infection of insect attack is reduced by 6.1% percent, and the growth ratio is up to 9.5 %.

Description

technical field [0001] The patent of the present invention relates to a compound fertilizer, in particular to a compound fertilizer for increasing the yield of lettuce. Background technique [0002] At present, there are some difficult problems in the application of fertilizers, such as the low utilization rate of fertilizers, the pollution of the ecological environment caused by excessive application of chemical fertilizers, etc.; in addition, dissolved organic carbon is an active substance in soil or water ecosystems. The composition and form transformation of various microorganisms and various nutrients in soil or water play an important role, and at the same time have a profound impact on the biogeochemical cycle and the toxicity and migration of heavy metals in the surface ecosystem. In view of the above problems, the present invention studies nano-additives and produces nano-scale materials, which not only have adsorption, dispersibility, rheology, porosity and surface...
