Tobacco ridging and mechanical fertilizer distribution device

Abstract

A tobacco ridging and mechanical fertilizer distribution device comprises a fertilizer hopper, a fertilizer discharging pipe, a connecting pipe and a fertilizer distribution appliance, wherein the fertilizer hopper is a hopper with a large opening in the top and a narrow opening in the bottom, and is communicated with the fertilizer distribution appliance through the fertilizer discharging pipe; the fertilizer distribution appliance is trapezoidal, adopts a flat nozzle, and comprises a housing, as well as separation strips and a fixing plate which are arranged in the housing; the housing comprises a front top plate, a back bottom plate and lateral plates, which are arranged in an encircling manner; a fertilizer inlet and a fertilizer outlet are formed in the housing; the fertilizer inlet is smaller than the fertilizer outlet, faces upwards and is communicated with the connecting pipe; the fertilizer outlet faces downwards; the separation strips are arranged between the front top plate and the back bottom plate, and distributed in rows from the fertilizer inlet to the fertilizer outlet, so as to divide the part, between the fertilizer inlet and the fertilizer outlet, of the housing into a plurality of fertilizer passages. The tobacco ridging and mechanical fertilizer distribution device has the advantages that the scattered fertilizing width of a fertilizer can be broadened, and fertilizer scattering, tobacco root absorption and the like are facilitated, so as to facilitate cigarette seedling growth and improve tobacco leaf yield; the release rate of the fertilizer efficiency is improved, so as to avoid late tillering of tobacco plants; the fertilizer can be applied uniformly in the fertilizing process due to the separation strips in the fertilizer distribution appliance, so that the fertilizing uniformity and the fertilizer utilization ratio are improved on the premise that the fertilizing efficiency is improved. Therefore, the tobacco ridging and mechanical fertilizer distribution device is beneficial to promotion of early growth and quick tillering of the tobacco plants and improvement of output value of tobacco leaves.

Description

technical field [0001] The invention relates to the technical field of tobacco mechanical equipment, in particular to a tobacco ridge machinery fertilizer distribution device. Background technique [0002] Fertilization in tobacco fields is a key factor affecting the growth and yield of tobacco plants. In recent years, nearly a thousand tobacco field soil nutrient tests have been carried out every year, and a set of mature and scientific fertilization methods has been formed by comprehensively considering factors such as previous stubble, variety, and soil type, and realized the harmony and unity of tobacco farmers' fertilizer input and tobacco leaf output benefits . In the scientific research on fertilization, the research on fertilization amount, formula ratio, top-dressing method and fertilization machinery is relatively in-depth and systematic, but there are few studies on the distribution of fertilizer in smoke ridges, and the fertilization method of double side fertil...

AI Technical Summary

Problems solved by technology

The second is that under the arid climate in recent years, some tobacco fields have experienced slow fertilizer release and late growth of tobacco plants, indicating that the period of fertilizer demand for tobacco plants does not match the period of fertilizer release from tobacco fields

Third, under the same fertilization amount and irrigation conditions, there are differences between tobacco fields that use mechanical fertilization and manual fertilization, and the growth period is later and the growth is weaker.

Manual fertilization is time-consuming and labor-intensive, with low operating efficiency and cannot meet the needs of normal ridge fertilization, and mechanical fertilization will become more and more

The existing mechanical fertilization has the problem that the fertilizer is too concentrated and it is difficult to contact with more moist soil, which is not conducive to the decomposition and absorption of fertilizer
