Dual-purpose fertilizer application machine for saline and alkaline land

Abstract

The invention discloses a dual-purpose fertilizer applicator for saline-alkali land, which includes a frame, and a fertilization ditch opener is arranged on a side of the frame close to a pull rod, and the fertilization ditch opener is connected with a disc scraper, and the fertilization ditch opener A seeding box is arranged at the rear, and a fertilization box is arranged at the rear of the seeding box. The inside of the fertilization box is divided into a solid fertilization box and a liquid fertilization box. The internal uniform shafts of the solid fertilization box and the liquid fertilization box are connected to the agitator in a curved shape, and the bottoms of the fixed fertilization box and the liquid fertilization box are threadedly connected to the discharge pipe and the nozzle. The dual-purpose fertilizer applicator for saline-alkali soil has the functions of ditching, sowing, fertilizing and film covering at the same time, and the fertilizing box is divided into a solid fertilizing box and a liquid fertilizing box, so that the fertilizing box can apply both solid fertilizer and liquid fertilizer. The liquid fertilization box can also be used for sprinkling water to realize multifunctional functions.

Description

technical field [0001] The invention relates to the technical field of garden machinery, in particular to a dual-purpose fertilizer applicator for saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. Some saline-alkali lands can still be fertilized and cultivated. Fertilization must take the soil into consideration. This is because: First, fertilization is only required when the soil is insufficient for a certain nutrie...

AI Technical Summary

Problems solved by technology

Because the supply of most nutrients is sufficient, otherwise it will cause waste and even cause crop poisoning

this is sometimes overlooked

Second, after the fertilizer is applied to the soil, there will be a series of changes, which will affect the fertilizer effect to varying degrees. If the soil is not considered, it is impossible to talk about the real rational fertilization

[0003] With the development of science and technology, fertilization can realize mechanized fertilization, which reduces the fatigue of manual fertilization. However, traditional fertilization machines do not have the functions of ditching, sowing, Solid fertilization cannot meet the needs of liquid fertilization, and it does not have the function of watering, which still leaves many problems for agricultural work
