2021年農(nóng)業(yè)發(fā)展新趨勢_移動苗床廣泛推廣—華耀農(nóng)業(yè)
移動苗床的操作原理: 移動苗床相比固定苗床，多出的配件就是苗床手輪、兩根苗床滾軸管、防翻卡裝置，以及苗床手輪等，移動苗床的操作方法主要是以滾軸為軸控制整個移動苗床網(wǎng)面的左右移動，進行操作，水平方向兩個相鄰的植床間可留有一個規(guī)范的作業(yè)通道，這套規(guī)劃設(shè)備***要是節(jié)省了很多的人力，方便移動噴灌機噴水施肥的作業(yè)同時，可也以使苗木噴灑的全面均勻。防翻卡的應(yīng)用避免了當(dāng)移動苗床移到一方時由于重心不穩(wěn)產(chǎn)生的側(cè)翻現(xiàn)象，雖然不起眼的小小裝置但是起到了移動苗床的整個核心作用。
溫室大棚育苗床設(shè)計移動苗床生產(chǎn)廠家的優(yōu)點：
1、節(jié)水，完全封閉的系統(tǒng)循環(huán)，可以達到 90%以上的水肥利用率；
2、作物生長速度快，每周苗齡可比傳統(tǒng)育苗方式至少提前 1 天，提高了設(shè)施利用率；
3、避免了植物葉面產(chǎn)生水膜，使葉片接受更多的光照和光合作用，促使蒸騰從根部吸收更多的營養(yǎng)元素；
4、可提供穩(wěn)定的根部基質(zhì)水氣含量，避免毛細根因靠近容器邊部及底部干旱而死；
5、使相對濕度容易控制，可保持作物葉面干燥，減少化學(xué)藥品的使用量；
6、栽培床下非常干燥，無雜草生長，可減少菌類滋生；
7、管理成本降低，即使是以手動操作進行營養(yǎng)液管理，一個人也可在 20-30min 內(nèi)可完成0.2-0.5ha.穴盤苗的灌溉；
8、 可以隨時使用，不受品種、規(guī)格、時間限制。
移動苗床的結(jié)構(gòu)：
移動苗床分三部分: 支架, 滾動體, 工作臺
1.苗床支架材料采用采用鍍鋅鋼管, 耐腐蝕, 苗床網(wǎng)采用熱鍍鋅鋼絲網(wǎng)
2.苗床的工作臺高度上可進行微調(diào)
3.工作臺在中間位置時可分別向左右移動300mm
4.邊框采用鋁合金, 重量輕, 耐腐蝕
5.移動苗床采用具有防翻限位裝置
6.移動苗床可提高溫室內(nèi)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
