Paddy field deep fertilization furrow opener

Abstract

The invention discloses a paddy field deep fertilization furrow opener. The paddy field deep fertilization furrow opener comprises a furrower and an up-and-down through mud guard, wherein the furrower is connected with the mud guard. The furrow opener further comprises a depth adjusting structure, wherein the depth adjusting structure comprises connecting holes formed on the back of the furrower and / or the mud guard and fixing rods located in the connecting holes to fix the furrower and the mud guard. In the adjusting process, the depth of the furrower is adjusted after a bolt is loosened without entirely dismounting; the adjusting is simple and convenient, the structure is simple, the slime can be effectively prevented from blocking fertilization holes, the deep fertilization demand in the paddy field is satisfied, the fertilizer use rate is effectively improved, and the paddy field deep fertilization furrow opener disclosed by the invention is wide in market application and spread prospect.

Description

technical field [0001] The invention relates to a fertilization device for assisting fertilization, in particular to a ditch opener for deep fertilization in paddy fields. Background technique [0002] my country is the world's largest consumer of chemical fertilizers, but the utilization rate of chemical fertilizers is low. Studies have shown that deep application of fertilizers is one of the important ways to improve the utilization rate of fertilizers. For example, deep application of ammonium bicarbonate and urea to the soil layer 6-10 cm below the surface can increase the utilization rate of nitrogen fertilizer by 115% and 35% compared with surface application. . At present, the deep application of fertilizers in dry land in my country has been widely used. It can be seen from this that fertilizers should be applied to different depths according to needs to improve the utilization rate of fertilizers. However, the current paddy field openers themselves do not have heig...

Problems solved by technology

For this reason the deep fertilization device that is used for paddy field is in order to overcome this problem, utilizes as publication number CN1742532A patent document, patent name: boat type deep fertilization ditch opener, it is done wide ditch knife, and in order to prevent that thin mud stops up fertilization opening, There will be a mud shield to prevent the mud from clogging the fertilization opening. If the depth adjustment method described in the former is used in the latter, since the paddy field opener is heavy, the heavy opener needs to be removed for each adjustment. , then adjust, and finally reinstall, the whole process requires at least two people, so the adjustment process is labor-intensive, and this depth adjustment method is not suitable for paddy field depth adjustment

[0004] The current deep fertilization equipment for paddy fields has seriously affected the utilization rate of fertilization fertilizers for paddy fields because of the inability to adjust the fertilization depth or the adjustment of the fertilization depth is too complicated.
