Vegetable seedling-raising irrigation machine

Abstract

The invention relates to the technical field of agricultural equipment, in particular to a vegetable seedling-raising irrigation machine. The vegetable seedling-raising irrigation machine comprises a water outlet pipe, a water inlet device and a pesticide inlet device are connected to the lower portion of the middle of the water outlet pipe through a transition pipeline, the water outlet pipe comprises two first water outlet pipes and two second water outlet pipes, a plurality of first water outlet holes are evenly distributed in the two first water outlet pipes, a plurality of second water outlet holes are formed in the half sections, close to a four-way pipe, of the two second water outlet pipes, the transition pipeline comprises the four-way pipe and a main pipeline, and the main pipeline is connected with the water inlet device and the pesticide inlet device. The vegetable seedling-raising irrigation machine can spray water and pesticide, the structural design of the water outlet holes in a first spray head and a second spray head is different, the second water outlet holes are formed in the second spray head in the half length direction, no water outlet holes are formed in the half part, away from the four-way pipe, of the second spray head, the amount of watering in the middle of a seedbed can be greater than the amount of watering on the two sides, therefore, the problem that the middle part of the seedbed is easy to dry is solved, and the irrigation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to an irrigation machine for raising vegetable seedlings. Background technique [0002] During vegetable seedling cultivation, if the seedbed is found to be dry (the soil moisture content is less than 16%-17%), it should be watered in time. In the process of watering, it is necessary to pay attention to controlling the amount of water: watering during the vegetable seedling period should not be too large, and the reasonable amount of watering is based on the fact that the soil around the seedling root system is moist after the water seeps down, and there is no water accumulation on the surface of the bed soil; general water seepage The depth is 8-10 cm. If there is too much watering, the soil humidity will be too high, and the seedlings will easily rot their roots, grow excessively or become susceptible to diseases. Because the temperature in the seedbed is not too ...

AI Technical Summary

Problems solved by technology

[0003] Existing vegetable seedling raising bases are planted in a large area. In order to improve irrigation efficiency, the existing vegetable seedling raising irrigation machines all use irrigation machines with a large radiation area. Using this type of irrigation machine has the following disadvantages: when irrigating, it can only be Irrigate the entire area within the coverage of the irrigation machine, and cannot selectively irrigate, and cannot adapt measures to local conditions to ensure uniform humidity in the seedbed
