Rice field fertilizing method

Abstract

The invention relates to a rice field fertilizing method. The method is characterized in that water flows into a channel through a channel water inlet, a flow sensor transmits the water flow information to a membrane pump through a control circuit, the membrane pump pumps quantitative liquid fertilizer from a fertilizer can according to the water flow information, the quantitative liquid fertilizer is sprayed into the channel through a nozzle, fertilizer and water are uniformly mixed together after water in the channel vertically and transversely flows so as to form the liquid fertilizer of a certain ratio, and the liquid fertilizer is filled into a rice field through a channel water outlet. By utilizing the rice field fertilizing method, workers can be relieved, time and labor are saved, farm operation is facilitated, fertilizer and medicine can be scientifically applied according to requirements of normal rice growth on the fertilizer and medicine and prevented from being unreasonably applied, so that cost is saved; and moreover, only parameters need to be preset when the method is used, no other operation steps are required, and the method is convenient, time-saving and labor-saving to operate when being used.

Description

technical field [0001] The invention relates to the field of crops, in particular to a paddy field fertilization method. Background technique [0002] Traditional fertilization methods for rice cultivation include full-layer fertilization, deep fertilization before turning, topdressing fertilizer, and root fertilization. Sprinkle the fertilizer on the field surface before autumn or spring plowing, and turn the fertilizer to the deep layer when plowing the ground; topdressing fertilizer is to spread the paddy field surface after transplanting rice seedlings and at various stages of rice growth; After transplanting rice seedlings, spray liquid fertilizer on rice leaves at various stages of rice growth; when fertilizing rice fields, manpower is required to go to the field to fertilize every time, which is time-consuming and laborious, and the amount of fertilizer is too much. Less than the proper fertilizer effect will also cause waste of fertilizer. Contents of the inventi...
