Embodiment Construction

[0043]A method for using fertilizer and water in a farm for a drip irrigation system, the steps are as follows:

[0044] (1) After the pig farm and cattle farm manure is collected, stored, transported and separated from solid and liquid, the liquid part enters the oxidation pond or anaerobic fermentation pond, and after 6 months of decomposing, fertilizer and water are obtained;

[0045] (2) A filter device is installed at the water inlet of the sewage pump, and the sewage pump extracts the fertilizer water in the middle of the oxidation pond, and uses a screen type backwash filter (20 mesh, 2 sets, 20-200m 3 / h) for filtration, and the suspended solids backwashed by the screen centrifuge use a homogeneous emulsification pump (20m 3 / h) for shearing and crushing, so that the suspended matter in the material is basically kept above 80 mesh (0.18mm);

[0046] (3) The volume of the static filter pool is 600m 3 , with a total length of 30m, a pool depth of 4m, and an average wid...

Abstract

The invention provides a method for applying farm fertilizer water to a drip irrigation system. Drip irrigation cultivation agronomic measures are combined, the reverse anti-blocking thought of filtration+emulsification+filtration is adopted, large-particle-size suspended solids are sheared and crushed while being filtered, and the problem that the drip irrigation system is blocked due to the factthat the particle size of the culture fertilizer water suspended solids is too large in particle size is solved. According to the method, crop drip irrigation cultivation agronomic measures are closely combined and fully utilized, the fertilizer water utilization period is long, the fertilization cost is saved, fertilizer water can be continuously matched at the flow rate of 10-200 m<3>/h according to different water flows of drip irrigation head and branch (bucket and trunk) canals, the method is suitable for large and medium-sized farms, and fertilizer water utilization can be completed within a short time. The method is simple in process, higher in nutrient content in fertilizer water compared with a filtering type process, and beneficial to improving soil fertility and crop yield andquality.

Description

technical field [0001] The invention relates to the field of agriculture and animal husbandry, in particular to a method for using fertilizer and water in a farm for a drip irrigation system. Background technique [0002] At present, my country's economy has entered a new stage of transformation and upgrading and supply-side reform. The development of agriculture and animal husbandry needs to focus on breaking through the three key problems of excessive resource utilization intensity, intensified non-point source pollution, and serious ecosystem degradation. In recent years, with the promulgation of various national laws and regulations, the requirements and standards for manure treatment of breeding enterprises have been gradually upgraded. Manure treatment has become a rigid demand of breeding enterprises and a bottleneck restricting the sustainable development of the breeding industry. [0003] At present, in the process of livestock and poultry manure treatment and resou...
