Abstract

The invention relates to a liquid fertilizer for the plantation of desert rice and a preparation method thereof. The liquid fertilizer is prepared by the following raw materials in weight part: adding 20-50 kg of a nitrogen fertilizer, 1-10 kg of a phosphate and potash fertilizer, 0.1-1 kg of a nitrifying ferment inhibitor and 0.1-3 kg of trace elements in each 100 L of pyroligneous liquor aqueous solution. According to the technical scheme of the invention, aiming at the characteristics of large desert soil pore and strong diffusion performance, nitrogen, phosphorus and potassium nutrients are quickly adjusted through the liquid fertilizer application process, and the ratio of nitrogen, phosphorus and potassium is relatively stable. Therefore, ammonia ions can be stably supplied. The plant acid is adopted as a fertilizer carrier, and the ratio of nitrogen, phosphorus and potassium in the solution is regulated and controlled. The activity of digestive enzymes is regulated and the utilization rate of nitrogen is improved. The formation of nitrified nitrogen is inhibited, so that the application effect of balanced fertilization is realized. According to the technical scheme of the invention, multiple nutrients required for the growth of plants can be provided, so that the crop yield and the crop quality are improved. The content of organic matters in the desert soil is rapidly increased, and the soil is improved. Therefore, the desert soil can be quickly restored to the grassland soil.

Description

technical field [0001] The invention relates to a liquid fertilizer, in particular to a liquid fertilizer for planting rice in desert. Background technique [0002] Desert soil is a soil type defined from the perspective of genetics, and it is a kind of soil developed in desert areas with drought, little rain and sparse vegetation. The soil basically has no obvious humus layer, the soil is loose, lacks water, the soil profile is almost all gravel, calcium carbonate surface accumulation, gypsum and salt accumulation are more, and the soil development degree is poor. The Horqin Sandy Land is located in Tongliao City, and its ecology is very fragile. There are large sand dunes on the surface and abundant water sources underground. In recent years, in order to quickly increase organic matter to restore sandy land vegetation, planting rice on sandy land is an effective method to restore soil vegetation. The specific method is: on the dune land with high sand content, use the me...
