Sweet potato plantation bioorganic fertilizer and production method thereof

Abstract

The invention relates to the technical field of bioorganic fertilizers, and concretely relates to a sweet potato plantation bioorganic fertilizer and a production method thereof. The organic fertilizer comprises, by weight, 140-170 parts of sweet potato residues, 90-120 parts of cassava residues, 20-40 parts of Artemisia carvifolia extraction medicine residues, 15-25 parts of isatis root extraction medicine residues, 45-65 parts of livestock manure, 15-35 parts of shell powder, 15-30 parts of slaked lime, 10-25 parts of humic acid, 5-15 parts of a nitrogen fertilizer, 3-8 parts of a potassium fertilizer, 0.2-0.7 parts of cellulase, 0.2-0.6 parts of ligninase, 0.1-0.35 parts of Azotobacter chroococcum, 0.1-1.1 parts of actinomyces and 0.2-0.7 parts of compound sodium nitrophenolate. The bioorganic fertilizer has the advantages of uniform fertility, high absorption and utilization rate, effective improvement of the soil structure, reduction of the use amount of pesticides, enhancement of the resistibility of crops to insect diseases, improvement of the quality and the output of agricultural products, and increase of peasants' income. The invention also provides the production method of the bioorganic fertilizer.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of bio-organic fertilizers, in particular to a bio-organic fertilizer for sweet potato planting and a preparation method thereof. [0003] 【Background technique】 [0004] Sweet potatoes are widely planted in China, from Hainan Province in the south to Heilongjiang in the north, and to the mountainous areas in western Sichuan and the Yunnan-Guizhou Plateau in the west. According to the climatic conditions, cultivation system, terrain and soil conditions of the sweet potato planting area, the sweet potato cultivation in China is generally divided into five cultivation areas: the northern spring potato area, the spring and summer potato area in the Huanghuai River Basin, the summer potato area in the Yangtze River Basin, and the southern sweet potato area. Summer and autumn potato area and southern autumn and winter potato area. Sweet potato starch is one of the main products of sweet potato processing...

Problems solved by technology

[0010] On the one hand, organic wastes such as waste slag left over from mass production in daily life will inevitably affect our living environment if not treated; on the other hand, although people are increasingly aware that composting technology should be used to turn waste into treasure, More organic fertilizers are used, but due to the immature technology, the fertility of organic fertilizers is not high, and the agriculture lacks enthusiasm for using them, they are still keen on chemical fertilizers; however, with the excessive use of chemical fertilizers, soil fertility declines and soil ecology is gradually destroyed
