Microorganism-containing organic compound fertilizer for stevia rebaudiana

Abstract

The invention relates to a microorganism-containing organic compound fertilizer for stevia rebaudiana, which is characterized by comprising the following components in parts by weight: 5-8 parts of natural nitrogen fertilizers with humic acid, 3-5 parts of phosphatic fertilizers, 6-7 parts of potash fertilizers, 2-3 parts of monopotassium phosphate, 3-5 parts of saccharin sodium solution, 25-30 parts of polymer water-absorbent resins and 60-72 parts of bioorganic fertilizers. The natural nitrogen fertilizers with humic acid comprise 2-3 parts of nitrogen fertilizers, 0.5-1 part of phosphatic fertilizers, 2-3 parts of potash fertilizers and 93.5-95.5 parts of humic acid by weight. The saccharin sodium solution contains saccharin sodium at the concentration of 0.4-0.6%. Compared with the chemical fertilizers, the organic compound fertilizer is green, nontoxic and harmless, has no side effect, resists drought, preserves water and fertility, keeps seedlings, improves the soil never to be hardened, regulates the pH value of the soil to be neutral, does not pollute ecological environment, prevents diseases and insect pests, reduces the usage amount of the pesticides by 50%, lowers the cost by 15-20%, increases the sugar degree by 2-3, increases the yield and benefit by more than 15-25% and ensures the seedling survival rate by more than 95%.

Description

technical field [0001] The invention relates to a microbial organic compound fertilizer, in particular to a stevia microbial organic compound fertilizer. Background technique [0002] Stevia is a perennial herbaceous plant. Its hometown is Brazil, South America. Brazil's virgin forest hillsides are overgrown with weeds. It is "the third sugar source in the world". Its dried leaves are processed into "stevia sugar", which is an ideal biological sugar for people's life Source and veritable natural pollution-free green food. [0003] In recent years, my country has introduced stevia planting. Due to the lack of scientific and technological management of stevia, the lack of understanding of the physiological characteristics of stevia and the scientific use of fertilizers, the majority of chrysanthemum farmers rely on the use of harmful chemical fertilizers and pesticides. Stevia has been planted for several years, and the dry leaf yield of stevia per acre is only 200-250 kg, wh...

Problems solved by technology

It is also required that the pollution-free fertilizer is rich in various trace elements, which cannot be achieved by chemical fertilizers, so special fertilizers must be developed for stevia planting to meet the growth requirements of stevia
