2021年农业发展新趋势_移动苗床广泛推广—华耀农业
移动苗床的操作原理: 移动苗床相比固定苗床，多出的配件就是苗床手轮、两根苗床滚轴管、防翻卡装置，以及苗床手轮等，移动苗床的操作方法主要是以滚轴为轴控制整个移动苗床网面的左右移动，进行操作，水平方向两个相邻的植床间可留有一个规范的作业通道，这套规划设备***要是节省了很多的人力，方便移动喷灌机喷水施肥的作业同时，可也以使苗木喷洒的全面均匀。防翻卡的应用避免了当移动苗床移到一方时由于重心不稳产生的侧翻现象，虽然不起眼的小小装置但是起到了移动苗床的整个核心作用。
温室大棚育苗床设计移动苗床生产厂家的优点：
1、节水，完全封闭的系统循环，可以达到 90%以上的水肥利用率；
2、作物生长速度快，每周苗龄可比传统育苗方式至少提前 1 天，提高了设施利用率；
3、避免了植物叶面产生水膜，使叶片接受更多的光照和光合作用，促使蒸腾从根部吸收更多的营养元素；
4、可提供稳定的根部基质水气含量，避免毛细根因靠近容器边部及底部干旱而死；
5、使相对湿度容易控制，可保持作物叶面干燥，减少化学药品的使用量；
6、栽培床下非常干燥，无杂草生长，可减少菌类滋生；
7、管理成本降低，即使是以手动操作进行营养液管理，一个人也可在 20-30min 内可完成0.2-0.5ha.穴盘苗的灌溉；
8、 可以随时使用，不受品种、规格、时间限制。
移动苗床的结构：
移动苗床分三部分: 支架, 滚动体, 工作台
1.苗床支架材料采用采用镀锌钢管, 耐腐蚀, 苗床网采用热镀锌钢丝网
2.苗床的工作台高度上可进行微调
3.工作台在中间位置时可分别向左右移动300mm
4.边框采用铝合金, 重量轻, 耐腐蚀
5.移动苗床采用具有防翻限位装置
6.移动苗床可提高温室内土地利用
New trend of agricultural development in 2021_ Extensive promotion of mobile seedbed - Huayao agriculture
Operation principle of mobile seedbed: Compared with the fixed seedbed, the more accessories of the mobile seedbed are the seedbed hand wheel, two seedbed roller tubes, anti overturning device, and seedbed hand wheel. The main operation method of the mobile seedbed is to take the roller as the axis to control the left and right movement of the whole mobile seedbed mesh. A standardized operation channel can be left between the two adjacent seedbeds in the horizontal direction. This set of planning equipment is the most important It can save a lot of manpower and facilitate the operation of spraying fertilizer by mobile sprinkler. At the same time, it can also make the seedlings spray evenly. The application of anti overturning card avoids the side overturning phenomenon caused by the unstable center of gravity when the mobile seedbed moves to one side. Although it is a small device, it plays the core role of the mobile seedbed.
The advantages of the mobile seedbed manufacturer are as follows:
1. Water saving and completely closed system circulation can achieve more than 90% of water and fertilizer utilization rate;
2. The growth rate of crops is fast, and the seedling age per week can be at least one day earlier than that of traditional seedling raising method, which improves the utilization rate of facilities;
3. It can avoid water film on plant leaves, make leaves accept more light and photosynthesis, and promote transpiration to absorb more nutrients from roots;
4. It can provide stable moisture content of root matrix and prevent capillary roots from dying due to drought near the edge and bottom of container;
5. It is easy to control the relative humidity of the crop and keep the use of chemicals;
6. The cultivation bed is very dry without weeds, which can reduce the breeding of fungi;
7. The management cost is reduced. Even if the nutrient solution is managed by manual operation, one person can complete the irrigation of 0.2-0.5ha. Plug seedlings in 20-30 minutes;
8. It can be used at any time and is not limited by variety, specification and time.
Structure of mobile seedbed:
Mobile seedbed is divided into three parts: support, rolling element and worktable
1. The seedbed support material is galvanized steel pipe, corrosion-resistant, and the seedbed mesh is hot-dip galvanized steel wire mesh
2. The height of working table of seedbed can be adjusted
3. When the worktable is in the middle position, it can move 300 mm to the left and right respectively
4. The frame is made of aluminum alloy with light weight and corrosion resistance
5. The mobile seedbed is equipped with anti overturning and limiting device
6. Mobile seedbed can improve the land use in greenhouse
