Rice flower-promoting and rice-ear-protecting organic foliar fertilizer containing biological selenium and zinc and preparation method thereof

Abstract

The invention discloses a rice flower-promoting and rice-ear-protecting organic foliar fertilizer containing biological selenium and zinc and a preparation method thereof. The rice flower-promoting and rice-ear-protecting organic foliar fertilizer is characterized in that a nutrient solution is prepared from the following raw materials in percentage by weight: 10% of bone meal, 20% of onion leaves, 20% of oilseed rape residue, 10% of edible vinegar, 30% of water hyacinth, 10% of rhodospirillum extracting liquid and 0.1% of fermentation flora I. The preparation method comprises the following steps: crushing the onion leaves and the oilseed rape residue, feeding the fermentation flora I, performing high-temperature and high-speed solid-state fermentation and decomposition for 24 hours, taking out a fermented product, then adding the bone meal and edible vinegar for performing acetification, further adding water hyacinth fermentation liquid and rhodospirillum into acetified raw materials again and mixing and stirring uniformly. Selenium and germanium in the rice flower-promoting and rice-ear-protecting organic foliar fertilizer disclosed by the invention exist in biological enzyme modes, and the rice flower-promoting and rice-ear-protecting organic foliar fertilizer further contains active small molecule peptides; therefore, when the rice flower-promoting and rice-ear-protecting organic foliar fertilizer is sprayed on leaves of rice in blooming and ear setting periods, the piece weight of ear setting grouting of the rice can be promoted, the occurrence of rice aspergillus can also be prevented, the quality of products can be increased, and the function of reducing chalkiness degree can be achieved.

Description

technical field [0001] The invention relates to a rice flower-promoting and ear-preserving organic foliage fertilizer containing biological selenium and zinc and a preparation method thereof, belonging to the technical field of organic fertilizers. Background technique [0002] In the method of high-yield rice planting, nutritional supplementation at the flowering and earing stage plays an important key point. In conventional planting, when flowering and earing, phosphorus and potassium fertilizers are generally applied to promote the saturation of earing, so as to Increase the weight of spikelets, but many growers use phosphorus and potassium elements in the growth period and sprinkle them on the soil. Now, due to the excessive application of chemical fertilizers, the soil in the paddy field is compacted, and the additional fertility is due to soil fertility. The efficiency of rice smut is not high, usually due to irrigation problems, resulting in nutrient loss, resulting...

[0002] In the method of high-yield rice planting, nutritional supplementation at the flowering and earing stage plays an important key point. In conventional planting, when flowering and earing, phosphorus and potassium fertilizers are generally applied to promote the saturation of earing, so as to Increase the weight of spikelets, but many growers use phosphorus and potassium elements in the growth period and sprinkle them on the soil. Now, due to the excessive application of chemical fertilizers, the soil in the paddy field is compacted, and the additional fertility is due to soil fertility. The efficiency of rice smut is not high, usually due to irrigation problems, resulting in nutrient loss, resulting in weak grains and high chalkiness. In order to avoid the spread of rice smut during rice growth, Daofengling, carbendazim, and three Cycloconazole and other pesticides are easy to cause the problem of pesticide residues, which not only affects the yield, but also reduces the quality of the harvested rice grains. How to use the characteristics of rice to absorb nutrients and use fermentation technology to spray on leaves can not only play a role Promoting the number and single weight of flowering and earing can reduce the chalkiness of rice grains, prevent the occurrence of rice smut, and realize organic planting of high-quality rice. It is a direction worthy of research by technicians in the field of modern organic fertilizers.
