Shallow root system greenhouse crop organic soil fertilizer and preparation method thereof

Abstract

By aiming at the growth characteristics of shallow-root crops, the invention relates to a shallow-root greenhouse crop organic soil fertilizer, sludge is subjected to a series of treatment to turn waste into wealth, the sludge is combined with traditional organic fertilizer to be fermented and then mixed with soil, the soil fertilizer capable of being directly used for crop planting is prepared, frequent fertilization and insecticide spraying are not needed when the soil fertilizer is used for planting vegetables, melons, fruits and other shallow-root-system crops, and multiple rounds of planting can be maintained; when the soil fertilizer on the surface layer is shoveled off and replaced with a new soil fertilizer layer after the soil fertilizer loses fertility, the continuous planting isrealized, the soil fertilizer losing fertility can be continuously recycled to prepare the new soil fertilizer, the whole preparation process is pollution-free, and the planted crops are non-toxic and harmless organic products and are safe and healthy.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer processing and manufacturing, and in particular relates to an organic soil fertilizer for shallow root greenhouse crops and a preparation method thereof. Background technique [0002] Greenhouse planting refers to a series of crops such as vegetables and fruits planted on the greenhouse covered with plastic film, and the season of listing can be artificially controlled. Greenhouse planting artificially creates a suitable ecological environment, adjusts the production season of crops, regulates market demand, and promotes high-quality and high-yield vegetables, which is one of the effective means to increase farmers' income. Greenhouse planting is generally suitable for crops with shallow root system and short harvest cycle to meet the supply demand of the market. According to the survey of most farmers who grow vegetables in greenhouses, the benefits are relatively obvious. However, t...

Problems solved by technology

China has relatively abundant fresh water resources. Water bodies such as rivers, lakes or ponds will produce siltation under natural action. If the water body is not used, siltation will at most lead to a decrease in water capacity; however, if it is a waterway in a river , ports, and even lakes or ponds used for breeding, the silted silt will have an adverse impact on production, so it is necessary to carry out regular or irregular dredging operations on these water bodies; take Dianchi Lake as an example, the largest in Yunnan Province The freshwater lake in Dianchi Lake is known as the Pearl of the Plateau. The dredging project of Dianchi Lake has been in progress. Up to now, the dredging of bottom sediment in Dianchi Lake has been carried out in two phases, and a total of more than 10 million cubic meters of bottom sediment has been dredged

At present, there is no scientific or accurate data on the amount of sediment that needs to be dredged in Dianchi Lake. Some experts have initially estimated that there are still about 80 million cubic meters to 100 million cubic meters of sediment in Dianchi Lake.
