In practice, the initial stage irrigation device 60, the pre-stage irrigation device 72, and the post-stage irrigation device 82 perform irrigation corresponding to different growth stages of pasture, respectively. Specifically, the initial stage irrigation device 60 and the pre-stage irrigation device 72 are primarily used to irrigate clear water, and the post-stage irrigation device 82 is primarily used to irrigate nutrient solution. For example, the first three days irrigate fresh water and the second four days irrigate nutrient solution.

In the present utility model, the longitudinal direction of the equipment frame 10 is defined as the front-rear direction, and one end of the equipment frame 10 where the drive sprocket 21 is located is the front, and the other end of the equipment frame 10 is the rear.
The utility model designs light supplementing and irrigation according to the growth characteristics of each stage of pasture. After the seeds run for one circle from the initial running point, the whole period cultivation of the pasture is completed, namely, the utility model realizes the cycle of planting, growing and harvesting the seeds. Specifically, the forage grass growth period is very short, light is not needed in the germination stage, even light shielding is needed, and seeds can be germinated only by proper temperature and humidity, so that the seeds are not illuminated and irrigated in the process of running along a straight path after being irrigated by sufficient clear water at an initial running point, and the process is the germination stage. When the seeds are in the early growth stage (1-2 days after germination), the leaves are tender, strong illumination is not needed, the illumination time is relatively short, the irrigation of nutrient solution is not needed, and in the later growth stage, sufficient photosynthesis is needed, the light intensity is enhanced, the light supplementing time is increased, and the nutrient solution is needed to be irrigated for supplementing nutrition to pasture due to consumption of substances. Aiming at the situation, the front part of the wavy path irrigates clear water and weak light supplement, and the rear part of the wavy path irrigates nutrient solution and strong light supplement. After one circle of operation, the pasture is cultivated, and the pasture is ready to be harvested.
When in operation, the power device 40 provides power to drive the two chain transmission devices 20 to synchronously operate, seeds are scattered in the planting trays and then placed on the tray frame 50, and then the lengthened pin chains 23 drive the tray frame 50 and the planting trays to intermittently and circularly operate along a set path. When the seed is at the initial operating point, the power unit 40 is stopped, and the seed is operated after being irrigated by the clear water of the initial irrigation unit 60. In the process of running along a straight path, the seeds are far away from the irrigation device and the light supplementing device, so that the seeds can be regarded as not being illuminated and irrigated and are in a germination stage. When the germinated seeds run into the front part of the wavy path, the germinated seeds are irrigated by clear water of the front stage irrigation device 72 and the weak light supplement of the weak light supplement device 71, and are in the front growth stage. After the seeds subjected to the early growth run into the rear part of the wavy path, the seeds are subjected to the nutrient solution irrigation of the later-stage irrigation device 82 and the strong light supplement of the strong light supplement device 81, and are in the later-stage growth stage. After the grass is turned back to the initial operating point after one circle of operation (one week), the grass is cultivated, and the grass is waited for harvesting.
The utility model has the advantages that:
According to the utility model, on one hand, timely light supplementing and irrigation are carried out on the pasture according to the growth characteristics of each stage of the pasture, the whole period cultivation of the pasture is completed after one circle of operation, the efficient and scientific production of the pasture is realized, resources (such as land resources and water resources) are saved, on the other hand, the space utilization rate is improved, the quantity of the cultivable pasture is increased, and the pasture yield is improved by virtue of the design of wave operation. In addition, the utility model automatically operates without personnel supervision, saves labor cost, has good and controllable pasture cultivation quality, and can maximize the input-output ratio. The utility model is suitable for places such as glass greenhouses, industrial plants, multi-span film greenhouse greenhouses and the like.
