Abstract

The invention discloses a rice-ratoon rice based basal fertilizer for first rice crops and a preparation method. The basal fertilizer for the first rice crops is prepared from nitrogen, phosphorus pentoxide, potassium oxide and zinc which are in a certain ratio. The method comprises the steps: A. weighing nitrogen, 46.2% of urea, 23.5% of ammonium chloride, 20.5% of ammonium sulfate, 55% of monoammonium phosphate, 60% of potassium chloride and zinc sulfate heptahydrate; B. carrying out stirring, uniform mixing and heating in a rotary drum; C. carrying out heating in a granulating drum, addingammonia and sulfuric acid, and carrying out physical aggregate characteristic granulating raw materials; D. carrying out screening, so as to obtain an even-grained fertilizer; E. cooling the granulated fertilizer, and spraying an anti-caking substance; and F. continuing to cool down the fertilizer, carrying out packaging, and carrying out sealing. The growth and development of the first rice cropsand the form of yield can be promoted, the germination and ear forming of ratoon axillary buds are facilitated, and thus, high yielding of rice of two crops is guaranteed. The basal fertilizer is good in water solubility and uniform in granules; the dissolving speed is high, and the nutrient supply is timely; and the concentration is high, and the absorption is easy. The nutritional requirementsof rice on a relatively long growing period can be met.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and more specifically relates to a first-season rice base fertilizer applicable to rice-ratio-regrowing rice, and also relates to a method for preparing first-season rice-based fertilizer applicable to rice-ratio The use of season rice base fertilizer. Background technique [0002] Rice is one of the main food crops in China, and stably increasing rice production is the key to ensuring food security. In the past 40 years since 1949, although the average annual increase of rice planting area was small, the average annual increase of per unit yield was 4.53%, which made the total rice output increase year by year, with an average annual increase of 5.69%. However, in recent years, it has become more and more difficult to increase the yield of rice per unit area, with an annual increase of less than 3%. At the same time, the pursuit of super-high yield in a single season by increasing investme...
