Irrigation and drainage system capable of applying fertilizer with water for rice field

Abstract

The invention discloses an irrigation and drainage system capable of applying a fertilizer with water for a rice field, and belongs to the field of rice field irrigation. According to the irrigation and drainage system capable of applying the fertilizer with the water for the rice field, before fertilization, inert gas is filled into a fertilizer barrel so as to enter a pneumatic shaking belt and overflow, so that on one hand, the pneumatic shaking belt is in a wave shaking shape, a certain stirring effect is generated on a liquid fertilizer at the bottom of the fertilizer barrel, and on the other hand, overflowing gas has a certain impact effect on the liquid fertilizer, and the uniformity of a water-soluble fertilizer is effectively improved; in addition, shaking force is longitudinally guided to a fluctuating bottom piece through a linkage longitudinal rope, the fluctuating bottom piece fluctuates, and the undissolved water-soluble fertilizer is driven to vibrate, so that compared with the prior art, the dissolution of the water-soluble fertilizer is obviously accelerated, the blockage of a fertilization pipeline is effectively avoided, and the fertilization efficiency is improved; and meanwhile, the concentration difference of the liquid fertilizer before and after application is small, so that the non-uniform growth of rice is effectively avoided.

Description

technical field

[0001] The invention relates to the field of paddy field irrigation, more specifically, to an irrigation and drainage system for paddy field fertilization with water. Background technique

[0002] Paddy irrigation is an important part of rice cultivation technology, including two aspects of irrigation and drainage. These two aspects coordinate with each other and work together on the growth and development of rice. During the whole life of rice, the response to water is more sensitive at the greening stage, jointing and booting stage, heading and flowering stage and grain filling stage, while the response to water at the seedling stage, tillering stage and fruiting stage is relatively slow. Therefore, water management in each growth period of rice should first ensure the water requirements of key growth periods, and then carry out reasonable irrigation according to the growth status of rice and the characteristics of climate change. Scientific irrigation can...
