Water-soluble fertilizer having effects for dredging pipeline and resisting obstruction used for drip irrigation system and application method thereof

Abstract

The invention provides a water-soluble fertilizer having effects for dredging pipeline and resisting obstruction used for a drip irrigation system, which belongs to the field of an agricultural fertilizer. The water-soluble fertilizer comprises the following components: 2-7 parts of a chelating agent, 3-8 parts of a pH conditioning agent, 50-95 parts of a scale inhibitor, and 1-1.5 parts of a sanitizing agent; wherein, the scale inhibitor is one or more of potassium pyrophosphate, tripotassium phosphate, ATMP, HEDP sodium salt or PBTCA.Na4; while fertilizing, the water-soluble fertilizer has the effects for dredging pipeline and resisting scales.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a water-soluble fertilizer used in a drip irrigation system with the function of dredging pipelines and preventing clogging and an application method thereof. Background technique [0002] my country is a large agricultural country, and agriculture occupies an important position in national production. In the process of agricultural modernization, intensive facility agriculture is developing vigorously. Among them, new irrigation methods are the key support direction of the state, such as drip irrigation, seepage irrigation, micro-irrigation, etc., which have the advantages of saving water. Resources, saving labor costs, water and fertilizer integration to improve fertilizer utilization and many other advantages. [0003] During the use of new irrigation methods such as drip irrigation, irrigation water and fertilizers are transported to the vicinity o...

Problems solved by technology

[0003] During the use of new irrigation methods such as drip irrigation, irrigation water and fertilizers are transported to the vicinity of the plants through pipelines after being prepared at the fertilizer distribution station, and dripped into the soil around the root system of the plants through micro-holes. During this process, the pipelines are affected by many aspects. Influenced by the impact, it will cause scaling on the inner wall, resulting in narrowing of the diameter of the pipe, and even blocking the capillary pores, resulting in unbalanced water and fertilizer in the field, reduced or even no harvest of local crops, which greatly affects the normal operation of the drip irrigation system.

When such problems occur, the conventional solution is to use acid to wash the pipeline, such as hydrochloric acid, nitric acid, etc. This method can only solve part of the problem, the effect is unstable, and it also brings other hazards, such as soil acidification and poor concentration control It is also easy to burn the roots, so it is generally not suitable for cleaning during the planting season
