Background

In agriculture, many plants such as watermelon, cotton and the like are difficult to survive in field planting, but can grow rapidly in a nursery room, and seedling cultivation is a seedling cultivation method which means that seedlings are cultivated in a nursery, a hotbed or a greenhouse and are ready to be transplanted into soil for planting. It can also refer to the stage of various organisms after artificial protection until they can survive independently. The seedling culture is a work with high labor intensity, time consumption and strong technical performance. In the past, most of the traditional open field direct seeding mode or the cold border, improved cold border and sunlight greenhouse seedling raising mode is adopted. Due to the influence of simple and crude equipment and natural conditions, the seedlings of the seedlings are long, poor in quality, irregular in size and high in cost, and the seedlings are often lack of seedlings due to natural disasters such as freezing injury or plant diseases and insect pests. Moreover, the traditional seedling raising technology is only based on experience, the technical errors are more, and especially the seedling raising is difficult to master and popularize only based on experience. Some present seedling culture devices have some weak points, the watering difficulty, it lacks water and receives the injury to make the seedling easily, do not have the function of strengthening photosynthesis, it is inefficient to cultivate the seedling, a large amount of manpowers have been wasted, to a great extent the survival rate of seedling has been reduced, unnecessary loss has been increased, the efficiency of growing seedlings has been reduced, and current seedling culture device is when transplanting the seedling, it is convenient inadequately, make the seedling receive the injury in transplanting easily, the survival rate that reduces transplanting of seedlings, for this reason, we propose an agricultural seedling culture device who is convenient for transplant the seedling plant.
