Description
Technical Field
The invention relates to the technical field of agricultural and forestry machinery, in particular to a blockage-controlling type irrigation and fertilization device and an irrigation system.
Background
In recent years, the water resource crisis in China is becoming serious, and the water resource crisis becomes one of the main bottlenecks restricting the sustainable development of the socioeconomic performance in China. However, the agricultural water-saving technology is used as a water-using household (the total water consumption accounts for 62.32% in 2017), the effective utilization coefficient of the farmland irrigation water is only 0.536, which is far lower than 0.70-0.80 of developed countries, and the agricultural water-saving technology has great promotion potential. Meanwhile, China is also a large chemical fertilizer using country, and according to the data of the national statistical bureau, the application amount of agricultural chemical fertilizers in China in 2017 is 5859.41 ten thousand tons, which accounts for 1/3 of the total application amount of agricultural chemical fertilizers in the world. At present, a relatively extensive agricultural management mode in China causes water and fertilizer resource waste and agricultural production cost increase, and simultaneously causes a series of environmental problems of non-point source pollution, farmland hardening, soil acidification and the like, so that the promotion of a water and fertilizer management technology is imperative. The water and fertilizer integration technology is an important mode for improving the comprehensive agricultural productivity. A typical water and fertilizer integration technical mode adopted in developed countries in the world at present is to irrigate and fertilize by means of a micro-irrigation system, so that the fine management of water and nutrients can be realized, and the utilization efficiency of the water and the fertilizer is effectively improved.
One of the main obstacles restricting the application and popularization of the technology is the blockage problem of the douche, the douche is taken as a key component for ensuring the efficient operation of the drip irrigation system, and the douche carries out energy dissipation on pressure water flow by means of an internal complex and long and narrow flow passage or micropore, so that the water flow is dripped into soil in a stable and uniform water drop shape. Due to the requirement of energy dissipation, the flow passage has a complex structure and a small size (usually 0.5-1.2 mm). In the water and fertilizer integrated system, because the fertilizer contains a large amount of chemical elements, the recombination and precipitation of chemical ions are easy to occur along with the injection of the fertilizer into the drip irrigation system, so that the blockage of an irrigation device is easily caused, the service life and the benefit of the water and fertilizer integrated system are directly determined, the uniformity of irrigation and fertilization is obviously reduced, the normal growth and development of crops are influenced, and the problem of short plates which restrict the development and the application of a water and fertilizer integrated technology is solved. Therefore, the problem of blockage of the irrigation emitter caused by synchronous fertigation of the water and fertilizer integrated system is effectively controlled, and the method has important practical value. At present, the problem of irrigation system blockage caused by fertilizer precipitation is solved mainly by injecting an acidic chemical reagent to reduce the pH value of irrigation water, so that production and accumulation of chemical precipitation can be obviously prevented, but a plurality of disadvantages exist, for example, adding acid may cause an excessively low pH environment, corrosion damage is caused to pipe components in a drip irrigation system, acid damage is caused to soil and crops, unsafety is caused to operators, and the like.
