Problems solved by technology

However, the unreasonable use of chemical fertilizers has brought a series of problems to the quality of cultivated land for a long time. The actual utilization rate of chemical fertilizers is less than 30%, the problem of soil pollution is serious, and pollution accidents occur frequently. More than 10% of the cultivated land area in the country has been polluted by heavy metals. , about half of the arable land in some cities in South China is polluted by toxic heavy metals such as cadmium, arsenic, mercury, and petroleum-based organic substances

Description

technical field [0001] The present invention relates to an organic fertilizer, and more specifically relates to a special organic fertilizer for grains. Background technique [0002] The development of planting in agricultural production is inseparable from fertilizers. my country's agriculture has a long history of 10,000 years. In ancient times, manure was called manure, and fertilization became manure field. Fertilization of farmland in my country began around the Yin and Shang dynasties, mainly based on the unearthed cultural relics that had wooden tools made of river mud at that time, and the oracle bone inscriptions of the Yin and Shang Dynasties that had recorded the characters for feces and choke, and there were inscriptions that fertilization can increase production. By the Warring States period, it had paid attention to and emphasized the fertilization of farmland. In ancient my country, animal manure was used as fertilizer at most. In the Warring States Period a...
