Synchronous ditching ridging fertilizing seeder for paddy field

Abstract

The invention discloses a synchronous ditching ridging fertilizing seeder for paddy field, comprising a power machine, a fertilizing power driving system installed on the power machine, a fertilizer ejecting system, a hanging device, a sowing system, a sowing power driving system and a ditching device. The hanging device is installed at the back part of the power machine and is connected with the sowing system to control the sowing system and the ditching device installed below a sliding plate in the sowing device to be lifted up or to be lifted down; the power machine is respectively drives the sowing system and the fertilizer ejecting system by the sowing power driving system and the fertilizing power driving system. The ditching device is synchronously ditched with water storing ditches, sowing ditches and fertilizing ditches, wherein ridges are formed between each two water storing ditches, and the sowing ditches and the fertilizing ditches are positioned on the ridges. The invention can realize synchronous ditching, synchronous ridging, synchronous fertilizing and paddy production with water saving and fertilizer saving, can increase the yield of the paddy to be more than 10%, save the fertilizer to be more than 20%, and has obvious ecological benefit and economic benefit.

Description

technical field [0001] The patent of the invention belongs to the technical field of sowing in agricultural machinery, and in particular relates to a paddy field synchronous ditching, ridge and fertilization seeder. Background technique [0002] my country is the largest consumer of chemical fertilizers in the world, but the utilization rate of chemical fertilizers is low, and the annual loss of chemical nitrogen due to volatilization, denitrification, leaching, etc. is as high as 12 to 14 million tons. Deep application of chemical fertilizers and the use of slow-release fertilizers or controlled-release fertilizers are important ways to improve the utilization rate of chemical fertilizers. Deep application of chemical fertilizers can quantitatively apply chemical fertilizers to the parts of crops with dense root systems below the surface, so that nutrients can be fully absorbed by crops and reduce volatilization and leaching. Slow fertilization or controlled release fertil...

AI Technical Summary

Problems solved by technology

Paddy field soil has a high moisture content and strong fluidity. During general paddy field operations, it is difficult to open fertilizer drainage ditches deep in the paddy field soil according to agronomic requirements; at the same time, water also partially dissolves chemical fertilizers, causing fertilizers to absorb moisture and increase viscosity. Problems such as reduced fluidity and blocked fertilizer outlets make it more difficult to implement deep fertilization for rice than other crops

The existing methods of sowing and fertilizing in paddy fields mainly rely on manual spreading before and after sowing or applying mechanical strips to the surface. There are problems with uneven fertilization, inability to apply deep fertilization, simultaneous fertilization and seeding, inability to ditch and ridge in the field, inability to cover with chemical fertilizers after sowing, and It is easy to lose with water or emit into the air, etc.
