Low-pressure high-frequency agricultural water-saving irrigation system and method

Abstract

The invention relates to a low-pressure high-frequency agricultural water-saving irrigation system and method. The system comprises a drip irrigation device, wherein the drip irrigation device is provided with a remote control electric valve, a controller, a fertilizer applicator and a pressure protector, and the method specifically comprises the following steps of (1), adjusting ground pile distribution, reducing pipe network water supply pressure, and controlling the pressure in a range of 0.05-0.08 Mpa; (2), carrying out illumination and soil moisture content analysis on crops, and carrying out precise irrigation and fertilization; and (3), irrigating according to the water demand of the crops in different growth periods, for example, keeping the irrigation time of each rotation irrigation group in the seedling period to be 20 minutes, keeping the irrigation time in the vigorous growth period to be 30-40 minutes, and determining whether irrigation is carried out or not according to the ground temperature and humidity in the next day. The method has the beneficial effects that the water is obviously saved, the use amount of chemical fertilizer is greatly reduced, energy (electricity) is saved, the income of farmers is greatly increased, and the method is green and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a low-pressure and high-frequency agricultural water-saving irrigation system and method. Background technique [0002] The large-scale promotion and application of drip irrigation technology in Xinjiang's agricultural production has alleviated the serious shortage of local water resources to a certain extent, and at the same time improved the quality of crops to varying degrees. However, there are still some problems: first, the irrigation process is based on experience and human operation, and the randomness is large; second, the irrigation facilities are old, there are misunderstandings about automatic or semi-automatic drip irrigation, and the understanding of precision fertilization and irrigation information management is limited. Resistance, which has a lot to do with the negative impact of the previously installed automatic water-saving irrigation; third, ...

However, there are still some problems: first, the irrigation process is based on experience and human operation, and the randomness is large; second, the irrigation facilities are old, there are misunderstandings about automatic or semi-automatic drip irrigation, and the understanding of precision fertilization and irrigation information management is limited. Resentment, which has a lot to do with the negative impact of the previously installed automatic water-saving irrigation; third, there is no actual water-saving, fertilizer-saving, power-saving, and labor-saving
