Planting soil formula

Abstract

The invention provides a planting soil formula. The planting soil formula is prepared by mixing raw soil, sand soil, sandy soil, a composted straw mixture, quartz sand and ceramsite according to a certain weight ratio, spraying a compound microelement diluting solution and mixing, and turning over and naturally evaporating until the moisture content is reduced to a certain extent. The raw soil iswaste soil which is 40cm below a surface soil layer in a land management process; the composted straw mixture is prepared by uniformly mixing corn straws, peanut straws, rice straws, wheat straws, broccoli roots and leaves and traditional Chinese medicine residues according to a certain mass ratio, adding sugarcane juice, and fermenting and composting. The sand soil is selected from the ancient Yellow River region; the compound microelement diluting solution is prepared by diluting agricultural non-point source sewage containing rich nitrogen and phosphorus. The planting soil formula has excellent water retention performance, can sufficiently provide nutrients needed by the growth of crops, can be directly used for carrying out seedling culture, crop planting and the like, and also can beused for ecological slope protection construction. By adopting the planting soil formula, agricultural straws, construction waste soil, non-point source pollution water resources and the like are recycled, the environment pollution is reduced and efficient utilization of agricultural water and soil is improved.

Description

technical field [0001] The invention belongs to the fields of agricultural planting, substrate preparation, waste utilization, non-point source pollution control and the like, and specifically relates to a planting soil formula. Background technique [0002] my country's water and soil resources are lacking and have been seriously lost. At the same time, a large amount of cultivated farmland is polluted, and the situation is grim. Although my country's total fresh water resources are 2.8 trillion cubic meters, accounting for 6% of global water resources, ranking fourth in the world. Since the 1980s, China's water shortage has gradually spread from local areas to the whole country, and the situation has become more and more serious, which has had a serious impact on agriculture and the national economy. According to statistics, my country's current total water shortage is estimated to be 40 billion cubic meters, and the annual drought-affected area is 2 million to 2.6 millio...

Problems solved by technology

However, previous studies have shown that the problem of residual soil generated after construction has not been properly resolved. Improper disposal of residual soil has caused serious social and environmental problems. The main problems are as follows: 1. A large amount of residual soil accumulates and damages the surface Vegetation pollutes the surrounding land, causing serious water and soil problems and directly endangering the surrounding environment; second, improper disposal of residual soil in some projects such as iron tower foundation projects and water conservancy projects may easily lead to geological disasters; third, if the residual soil accumulated in mountainous areas encounters large-scale Precipitation is very likely to induce disasters such as mountain torrents, mudslides, and landslides, directly endangering the safety of people's lives and property; Fourth, with the development of cities and the continuous expansion of construction land, many high-quality land around cities and towns are occupied by construction. The soil of the land has also been damaged, exacerbating the scarcity of soil resources

However, there are still many problems in the utilization of agricultural waste resources in our country. Because the people in our country still do not have a good understanding of agricultural waste, and the technical conditions are relatively lagging behind, so the utilization of agricultural products is also very backward.

In terms of fertilization, the efficiency of straw bio-decomposition technology is low, and there is still the problem of nutrient loss during the decomposition process
