Special formulated fertilizer for summer sesames and preparation method thereof

Abstract

The invention discloses a special formulated fertilizer for summer sesames and a preparation method thereof. The special formulated fertilizer for the summer sesames is prepared from the following rawmaterials in percentage by weight: 15.0 to 30.0 percent of alginic acid-containing urea, 10.0 to 28.0 percent of release-controlled urea, 15.0 to 30.0 percent of monoammonium phosphate, 10.0 to 30.0percent of potassium chloride, 5.0 to 15.0 percent of charcoal, 5.0 to 20.0 percent of organic matter ingredients, and 5.0 to 18.0 percent of micro element fertilizer. The special formulated fertilizer for the summer sesames is prepared through compounding, mixing, metering and packaging, and is applied to sesame planting, producing or disease. The special formulated fertilizer for the summer sesames provided by the invention is capable of promoting the growth and development of the summer sesames, improving the sesame quality, and reducing plant diseases and insect pests of summer sesames, iseasy to get raw materials, simple in processing technology, green and environmental-friendly, gives consideration to soil environment capacity, and is convenient to apply by farmers.

Description

technical field [0001] The invention relates to the technical field of agricultural soil and fertilizer, in particular to a special formula fertilizer suitable for summer sesame in the Huanghuai region and a preparation method thereof. Background technique [0002] Sesamum (Sesamum indicum), also known as sesame and flax, is the seed of flax. The oil content of sesame seeds is as high as 55%, which is one of the main oil crops in China and has high application value. [0003] Summer sesame is an oil crop with a short growth period. Scientific and balanced fertilization is the most direct and effective means to regulate the nutritional level and nutritional imbalance of summer sesame, and plays a very important role in its growth and development. In order to increase the production and income of summer sesame, it is necessary to carry out appropriate nutrient supplementation according to the soil nutrient conditions. In the cultivation of summer sesame in the Huanghuai regi...

Problems solved by technology

[0005] (1) Apply simple chemical fertilizers or compound fertilizers with simple and fixed ratios of nitrogen, phosphorus, and potassium. The ratio of nitrogen, phosphorus, and potassium nutrients is unscientific and does not meet the law of fertilizer requirements of summer sesame. The amount of fertilizer applied or the intensity of nutrient release exceeds the soil The carrying capacity of the environment not only causes waste of nutrients and pollution of the agricultural environment, but also affects the growth and development of cotton and the formation of quality; (2) Decomposed organic fertilizers are time-consuming and inconvenient to apply. In practice, the application of organic fertilizers on sesame crops is almost zero; (3) Too many times of topdressing, which is labor-intensive; (4) Commonly used chemical fertilizers lack important trace elements required for the growth and development of summer sesame, and need to be sprayed on leaves. Time-consuming
