The invention discloses a rice lodging-preventing fertilizing device and a lodging-preventing fertilizing method, and relates to the technical field of rice fertilization, the rice lodging-preventing fertilizing device comprises a water tank, a liquid pump is arranged on the water tank, the liquid pump is connected with a bottom flow dividing pipe through a first connecting pipe, and the bottom flow dividing pipe is communicated with a hose; the end, away from the bottom flow dividing pipe, of the hose communicates with a suspended blade back spray head. According to the invention, the lodging-preventing fertilization design is adopted for the back surfaces and rhizomes of rice leaves, the suspended leaf-back nozzles are arranged at the bottoms of the hoses, and on one hand, airflow generated by the suspended leaf-back nozzles can suspend the suspended leaf-back nozzles so as to carry out targeted fertilization and spraying on the back surfaces and rhizomes of the rice leaves; on the other hand, air flow generated by the suspended leaf back spray head can enable liquid near the roots of the rice to be blown away by wind power and be leaked out of soil, and the fertilization mode can improve the air permeability of the soil and increase the oxygen content in the soil, so that the effect of rooting is achieved, the root activity is improved, and the effects of strengthening the roots and resisting lodging can be achieved.

    本发明公开了一种水稻防倒伏施肥装置和防倒伏施肥方法,涉及水稻施肥技术领域,包括水箱,所述水箱上设置有液泵,所述液泵通过第一连接管连接有底部分流管,所述底部分流管连通有软管,所述软管远离底部分流管的一端连通有滞空叶背喷头。本发明采用水稻叶背面、根茎处针对防倒伏施肥设计,在软管的底部设置滞空叶背喷头,滞空叶背喷头产生的气流一方面可以将其滞空从而进行水稻叶背面、根茎处针对性施肥喷洒,另一方面滞空叶背喷头产生的气流可以使得水稻根部附近的液体被风力吹开,漏出土壤,这样的施肥方式,可以增加土壤的透气性,增加土壤中的氧的含量,进而起到弄根的作用,根系活力增加,可以起到了强根抗倒伏的作用。
