Description

Wheat cultivation is with circulation drip irrigation device

Technical Field

The invention relates to the field of agricultural mechanized planting, in particular to a circulating drip irrigation device for wheat cultivation.

Background

Drip irrigation is the local irrigation of the roots of crops by using plastic pipes to send water to the roots of crops through orifices or drippers on the capillary pipes. Drip irrigation is the most effective water-saving irrigation mode in arid water-deficient areas, and can effectively improve the utilization rate of water. Compared with spray irrigation, the drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to improve the fertilizer efficiency by more than one time. The method is suitable for irrigation of fruit trees, vegetables, economic crops and greenhouses, and can also be used for irrigation of field crops, such as drip irrigation of wheat and the like, in arid places with water shortage.

With the development of science and technology, technicians in related fields also greatly optimize the drip irrigation mode of wheat, and for more accurate comparison, for example, a circulating drip irrigation device for wheat cultivation is disclosed in the Chinese patent with the publication number of CN 209914669U; when the wheat cultivation pot is used, the cultivation pot body is driven to rotate through the rotation of the motor, so that the spray head is more uniformly sprayed on the cultivation pot body, water in the cultivation pot body flows out through the filtering holes, and the wheat is prevented from being rotten due to the fact that the water is stored in the cultivation pot body; carry out the primary filtration to water through filtering the otter board, water after the filtration flows down along filtering the otter board, and impurity is kept apart on filtering the otter board, piles up to certain thickness when impurity, when influence water filtration, can manually take down filtering the otter board, clears up the change, reuse.

However, the above-mentioned comparison file has only solved the problem of filtering the circulating water at the in-service use in-process, if need carry out liquid manure drip irrigation to wheat, still need stir water and fertilizer before driping irrigation and mix, but above-mentioned comparison file does not possess the function of stirring and mixing water and fertilizer, if water and fertilizer do not pass through abundant stirring, the fertilizer is difficult to even blending into aquatic, and then leads to the not fertilizer that melts to block up the drip irrigation hole more easily, and, the not fertilizer that melts also leads to the fertilization inequality to wheat easily, thereby influences the growth cycle of follow-up wheat.

Therefore, under the view point stated above, the technical means of fully stirring and mixing water and fertilizer in the process of carrying out the circulation drip irrigation on the wheat in the prior art still has room for improvement.
