Problems solved by technology

The normal growth and development of rice requires more nutrients, and relying solely on soil supply cannot meet the needs of rice growth and development
At present, chemical fertilizers are often applied in batches and times to ensure sufficient nutrient supply for rice, but it is time-consuming, laborious, and costly. In addition, with the excess of a large number of nutrient elements, the content of trace elements in the soil can no longer meet the demand. Micronutrient deficiencies are also on the rise
Although a variety of organic fertilizers have been developed at present, their nutrients are easy to volatilize and lose, the fertilizer effect is fast, and they are not durable, which needs to be solved urgently

Abstract

The invention discloses a preparation method of a moisture-fertility preserving rice fertilizer. The preparation method comprises the following steps: mixing sodium carboxymethyl cellulose and absolute ethyl alcohol and stirring uniformly; sequentially adding water and borax in a stirring state; after complete addition, continuously stirring, washing and drying to obtain pretreated borax; adding bamboo charcoal, fatty alcohol-polyoxyethylene ether, absolute ethyl alcohol and toluene into the pretreated borax and mixing uniformly; adjusting the temperature; adding sodium hydroxide, propylene oxide and chloromethane and mixing and stirring; standing; heating for reacting; removing the solvent and adjusting the pH value of the system to 6.2-6.6; washing and drying to obtain borax composite bamboo charcoal; fermenting human / animal excreta, plant straw, pond sludge, tapioca flour and biological bacteria in a fermentation tank; adding the borax composite bamboo charcoal, ground calcium carbonate, kaolin, glimmerite, sodium silicate, EDTA chelated zinc, EDTA chelated manganese and compound sodium nitrophenolate and mixing uniformly; and granulating to obtain the moisture-fertility preserving rice fertilizer.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a method for preparing water- and fertilizer-retaining rice fertilizer. Background technique [0002] Rice is native to tropical Asia, and after being widely planted in China, it gradually spread to all parts of the world. The rice grains produced by rice are called rice or rice after shelling. Nearly half of the world's population feeds on rice. Compared with other crops, The digestibility and absorption rate of nutrients contained in rice are relatively high, which is most suitable for the needs of the human body. The normal growth and development of rice requires more nutrients, and relying solely on soil supply cannot meet the needs of rice growth and development. At present, chemical fertilizers are often applied in batches and times to ensure sufficient nutrient supply for rice, but it is time-consuming, laborious, and costly. In addition, with the excess of a ...
