Problems solved by technology

[0005] On the one hand, due to the poor structural size of the Venturi fertilizer applicator, it cannot generate enough negative pressure to absorb fertilizer
[0006] On the other hand, because there is no effective method for the selection and use of the Venturi fertilizer applicator, the purchased Venturi fertilizer applicator cannot match the irrigation system, resulting in the failure of the best Venturi fertilizer applicator
[0007] Therefore, in the field of water and fertilizer integration, there is an urgent need for a Venturi fertilizer applicator selection and use method to solve the current problems of Venturi fertilizer applicator selection and fertilizer absorption, thereby promoting the efficient use and promotion of water and fertilizer integration technology

Abstract

The invention discloses a pipeline system, a venturi fertilizer applicator type selecting method, and applications thereof, and belongs to the field of water fertilizer integration. The venturi fertilizer applicator type selecting method comprises following steps: based on on-site factors, an irrigation device matching the on-site factors is selected, wherein the irrigation device comprises certain characteristic parameters, the on-site factors comprises one or a plurality of factors selected from crop, soil type, and irritation rules; based on the characteristic parameters, the working flowamount of the pipeline system and the outlet flow amount of a venturi fertilizer applicator contained by the pipeline system are determined, so that the venturi fertilizer applicator is determined based on the working flow amount of the pipeline system and the outlet flow amount of the venturi fertilizer applicator. The venturi fertilizer applicator type selecting method is capable of solving problems in the prior art that venturi fertilizer applicator type selecting is difficult, and fertilizer absorption is difficult to realize, time and cost are saved greatly, and it is beneficial for waterfertilizer integration high efficiency utilization.

Description

technical field [0001] The invention relates to the field of water and fertilizer integration, in particular to a pipeline system, a type selection method for a Venturi fertilizer applicator and an application thereof. Background technique [0002] Water is an important material for people to survive, especially for agricultural production, and agricultural water accounts for a large part of the total water consumption. Therefore, it is necessary to develop high-efficiency water-saving technologies in agriculture to improve water utilization. [0003] The growth of crops is inseparable from the supply of fertilizers, so it is a more promising choice to combine fertilization and water-saving technology to develop water-fertilizer integration technology. The key device of water and fertilizer integration technology is the fertilizer applicator, and the Venturi applicator has become the most popular fertilization device for farmers because of its low price and no need for exte...
