Problems solved by technology

[0002] The total amount of fresh water resources in my country is about 2.8 trillion cubic meters, accounting for 6% of global water resources. The total amount of fresh water ranks fourth in the world, but the per capita fresh water resources are 2240m 3 , which is only 25% of the world's per capita share; in addition, my country's directly usable freshwater resources only account for about 2.7% of freshwater resources, which cannot meet the needs of agricultural production water consumption. Tension has become one of the inevitable trends in my country's agricultural development

Embodiment 1

[0043]Prepare a polyether-modified silicone surfactant aqueous solution (abbreviated as DY-ET100 aqueous solution) with a concentration of 1.33mL / L (equivalent to a mass concentration of 0.133%), and drip-irrigate 1.5L of DY-ET100 aqueous solution into the clay soil , the drip irrigation time is 1h, and then directly measure the diffusion of the aqueous solution in the soil, and use the Photoshop tool to count the diffusion radius and diffusion area of ​​the aqueous solution at the soil surface and at a depth of 3cm. The statistical results are shown in Table 1 and figure 1 with 2 .

Embodiment 2

[0045] Carry out test according to the method for embodiment 1, difference is that soil is loamy soil quality, and statistical result is shown in Table 1 and image 3 .

Embodiment 3

[0047] Test according to the method of embodiment 1, difference is that soil is sandy soil quality, and statistical result is shown in Table 1 and Figure 4 .

Abstract

The invention belongs to the technical field of fertilizer modification and specifically relates to a modified fertilizer and application thereof. The modified fertilizer provided by the invention comprises individually packaged polyether-modified organosilicon surfactant and fertilizer. By using the polyether-modified organosilicon surfactant and the fertilizer cooperatively, dispersity of the fertilizer in soil is improved by the utilization of a hydrophilic group and a hydrophobic group of the polyether-modified organosilicon surfactant, the fertilizer is dispersed on the surface layer, infiltration amount of the fertilizer in the soil is reduced, and the fertilizer is diffused to soil around the plant root to the maximum. Test results of the embodiment show that the modified fertilizeris irrigated in the soil by a drop irrigation method, the fertilizer is centralized in the soil layer of 0-9 cm deep and is less distributed in the soil layer of 12 cm deep, and utilization rate of the fertilizer is high.

Description

technical field [0001] The invention belongs to the technical field of fertilizer modification, and in particular relates to a modified fertilizer and its application. Background technique [0002] The total amount of fresh water resources in my country is about 2.8 trillion cubic meters, accounting for 6% of global water resources. The total amount of fresh water ranks fourth in the world, but the per capita fresh water resources are 2240m 3 , which is only 25% of the world's per capita share; in addition, my country's directly usable freshwater resources only account for about 2.7% of freshwater resources, which cannot meet the needs of agricultural production water consumption. Tension has become one of the inevitable trends in my country's agricultural development. [0003] Drip irrigation is a common way to effectively utilize water resources in water-scarce areas. This irrigation method is to transport water through the whole pipeline, and slowly irrigate in small quan...
