Functional fertilizer special for rice and preparation method thereof

Abstract

The invention discloses a functional special fertilizer for rice. The functional special fertilizer comprises the following raw materials in parts by weight: 90-120 parts of nitrogen fertilizer, 75-110 parts of phosphate fertilizer, 60-90 parts of potash fertilizer, 180-200 parts of organic fertilizer, 8-16 parts of trace element fertilizer, 2-3 parts of compound sodium nitrate and 4-8 parts of ground phosphate rock. The method comprises the steps: weighing the nitrogen fertilizer, the phosphate fertilizer, the potash fertilizer, the organic fertilizer, the trace element fertilizer, the thecompound sodium nitrate and the ground phosphate rock according to a ratio; placing the weighed raw materials in a stirrer to be mixed and stirred, agglomeration granulation, drying, cooling and screening are performed on the mixed raw materials in a rolling bed through a granulator through humidification and heating, and obtaining the product. The functional formula not only has the advantages of reasonable inorganic fertilizer nutrient content and quick fertilizer efficiency exertion, but also has the advantages of complete organic fertilizer nutrients, long fertilizer efficiency and stable performance, and meanwhile, the functional formula contains organic compounds so that the fertilizer has a certain prevention and treatment effect on diseases and pests.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special functional fertilizer for rice and a preparation method thereof. Background technique [0002] Rice, also known as sorghum, milo, etc., is an annual herb. High-yielding crops known as "hardcore crops" by the masses. Stems are tall. The shape is like a reed, but the middle is solid, the leaves are also like a reed, the ears of millet are like a big broom, and the grains are as big as peppercorns, turning red and black. Sex likes warmth, drought resistance and waterlogging tolerance. According to characters and uses, it can be divided into edible rice, rice for sugar, rice for broom, etc., which are widely cultivated in China. Rice can be processed into sorghum noodles, which can be made into a variety of foods that are popular with the masses. In recent years, it has become a meal for welcoming guests. In addition to food, rice can also be used to make starch, s...

Problems solved by technology

[0003] The normal growth and development of rice requires more nutrient elements, especially the three elements of nitrogen, phosphorus, and potassium. Simply relying on soil supply cannot meet the needs of rice growth and development. At present, it is often used in multiple times. Chemical fertilizers are used to ensure sufficient nutrient supply for rice, but it is labor-intensive, time-consuming, and costly. With the increase in the application of nitrogen, phosphorus, and potassium, a large number of nutrient elements are relatively enriched, which not only reduces the utilization rate, but also wastes resources. polluted the environment

With the excessive application of macronutrient fertilizers, the content of trace elements in the soil can no longer meet the demand, and rice trace element deficiency is also increasing. Although a variety of special fertilizers for rice have been developed, they only involve different ratios of macroelements or The proportion of organic nutrients and macroelements is different. After the related fertilizer products are applied to the soil, the nutrients are easy to volatilize and lose, the fertilizer effect is fast, not long-lasting, and it is easy to cause diseases and insect pests
