Multifunctional Slow Release Fertilizer

Abstract

The invention relates to a multifunctional slow-release fertilizer applicator. The multifunctional slow-release fertilizer applicator comprises a through water pipe, a fertilizer container, a fertilizer-water drainage pipe and a branched pipe, wherein the fertilizer-water drainage pipe is arranged in the fertilizer container, extends outwards and is communicated with the through water pipe; through holes are formed in the fertilizer-water drainage pipe, and the fertilizer-water drainage pipe is connected with the fertilizer container; the through water pipe is provided with a water inlet and a water outlet; an openable-closable fertilizer feeding hole is formed in the upper end of the fertilizer container; one end, close to the water inlet, of the through water pipe is communicated with the lower end of the branched pipe, the upper end of the branched pipe is communicated with the fertilizer container, and the water outlet of the through water pipe extends out of an irrigation pipe section; in a fertilizer applying process, water can be replenished to the fertilizer container by virtue of the branched pipe through the water inlet. According to the multifunctional slow-release fertilizer applicator, integrated fertilizer-water fertigation can be carried out by virtue of soluble solid fertilizers, so that the fertilizer is rapidly, stably and efficiently applied; furthermore, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to a watering system for applying fertilizers, in particular to a multifunctional slow-release fertilizer applicator. Background technique [0002] Looking at today's irrigation field, the irrigation water utilization coefficient of micro-irrigation can reach more than 90%. Therefore, micro-irrigation technology has developed rapidly in my country since the "Ninth Five-Year Plan". To implement the No. 1 Central Document and the spirit of the Central Water Conservancy Work Conference in 2011, the national planning and development of water-saving irrigation projects covers an area of ​​about 195 million mu, including 48.16 million mu of micro-irrigation. A new round of upsurge in vigorously developing water-saving irrigation nationwide has emerged . Modern micro-irrigation technology can realize the integrated operation of irrigation and fertilization, so it is necessary to inject fertilizer into the pressure pipeline of the irrigati...

AI Technical Summary

Problems solved by technology

[0011] 1. In actual use, it is found that after the fertilizer liquid is added to the fertilizer liquid pipe D4, since the pressure at both ends of the fertilizer liquid pipe D4 of the device is in a relatively balanced state, the fertilizer liquid in the fertilizer liquid pipe D4 is gradually diffused through molecular diffusion. Slowly enter the water pipe D3 and enter the irrigation pipe section D8, so the amount of fertilizer output is small, and the concentration of fertilization is too low, making it difficult to apply enough fertilizer within the determined irrigation time

[0012] 2. This device is only suitable for applying fertilizer liquid, that is, the pre-dissolved and prepared fertilizer liquid is added to the fertilizer liquid pipe D4, and it is not suitable for the use of soluble solid fertilizers.

[0013] Since the fertilizer liquid pipe D4 of this device is directly connected with the water pipe D3 up and down, the connecting surface is usually relatively large (otherwise the concentration of the liquid fertilizer is too low), when the solid fertilizer is added to the fertilizer liquid pipe D4, it will directly fall into the water pipe Even if it is dissolved during the water pipe transportation, the concentration of the fertilizer solution is often high or there are still a lot of solid fertilizers that have not been dissolved. The preset fertilization effect cannot be achieved.

[0014] (3, because dissolvable solid fertilizer cannot be applied, and the volume of the fertilizer liquid pipe is relatively small, therefore, if sufficient fertilization rate is to be guaranteed, in the fertilizer liquid pipe of this existing device, it is necessary to frequently add fertilizer liquid ,kind of hard
