Description

Air-assisted rice side deep fertilizer applicator

Technical Field

The invention relates to an agricultural machine for rice side deep fertilization, in particular to an air-assisted rice side deep fertilizer applicator.

Background

Rice is one of the main grain crops in China, is widely planted in the north and south areas of China, the planting area reaches 2992 ten thousand hectares, about 60 percent of people use rice as staple food, and the rice has a great significance in guaranteeing the safe production of food in China. Fertilization is an indispensable operation link in the rice production process, and reasonable application of the chemical fertilizer can effectively promote rice seedlings to rapidly grow roots, leave leaves and tillere, increase yield and harvest, otherwise, the utilization rate of the fertilizer is reduced, and water resources are polluted. The conventional fertilization mode mainly comprises conventional fertilization and side deep fertilization, the conventional fertilization mainly comprises the steps of scattering fertilizers on the ground surface through manpower or a fertilizer scattering machine and then mixing the fertilizers with soil through a tillage machine, and the conventional fertilization mode has the defects of high labor intensity, uneven fertilizer scattering and application, easy excessive use of the fertilizers, inconsistent fertilizer absorption amount of rice seedlings, uneven growth and height of rice and uneven heading size, and direct influence on the yield and quality of the rice. And soil erosion and environmental pollution are caused, so that soil is hardened, the quality of the soil is reduced, and a series of environmental problems are caused. The side deep fertilization is that during the rice transplanting, fertilizer is applied at the side deep position 3-5cm away from one side of the rice seedling root system and 5-8cm deep of soil, the fertilization mode can apply base fertilizer, striking root fertilizer and tillering fertilizer at one time, the fertilization frequency is reduced, the labor intensity is reduced, and the fertilizer is applied at one side of the rice seedling root system, so that the root system can conveniently absorb nutrients, the root injury and seedling burning are avoided, the fertilizer loss is avoided due to the covering of soil, and the utilization rate of the fertilizer is improved.

Therefore, the deep fertilizer application mode is a fertilizer application mode which saves cost and enhances the fertilizer application effect, can reduce the loss of the fertilizer on the soil surface, improve the utilization rate of the fertilizer, reduce the pollution to the environment and improve the rice yield. The existing side deep fertilizing machine mainly adopts pneumatic conveying, fertilizer is conveyed to a vertically arranged discharging pipe through air pressure, a fertilizer discharging port is formed in a lower port of the discharging pipe, a furrow opener is arranged on the lower side of the discharging pipe, and the fertilizer falls into soil through the discharging pipe and the furrow opener. The existing air-assisted rice side deep fertilizer applicator has the following problems: the fertilizer outlet is easy to be affected with damp due to backward flowing of mud and water, the damp fertilizer is mixed with the slurry and adhered to the fertilizer outlet, and the fertilizer cannot be blown off by wind force, so that the fertilizer is easy to block at the fertilizer outlet, and the problems of uneven fertilization and poor continuity are caused; the furrow opener in the prior art is easy to be back-flowed by muddy water, so that the fertilizer is not deep enough, the growth of seedlings is influenced, and the yield of rice is reduced.
