如何既能便利地使用苗床,又能更有效地利用溫室空間,成了溫室用戶的進(jìn)一步需求。室內(nèi)移動(dòng)苗床在此需求上產(chǎn)生了1移動(dòng)式苗床在使用要求下產(chǎn)生，栽培苗床一般采用輕鋼結(jié)構(gòu),固定于地面,高度以適宜于人彎腰操作而定,一般為0.7m,寬度以人彎腰伸臂可以輕松操作苗床上作物而定,一般取1.5-2.0m:長(zhǎng)度則依溫室長(zhǎng)度和使用要求而定，2移動(dòng)式苗床的設(shè)計(jì)及應(yīng)用是通過(guò)多架苗床共用一條道路來(lái)提高溫室使用率的,其外形尺寸與固定苗床類似,但可以沿寬度方向作左右移動(dòng)60cm。使用移動(dòng)苗床,溫室內(nèi)每跨只需預(yù)留一條道路即可,大大節(jié)約了溫室使用面積,使溫室利用率可高達(dá)80%以上。

How to use the seedbed conveniently and the greenhouse space more effectively has become the further demand of greenhouse users. Indoor mobile seedbed produces 1 mobile seedbed under use requirements, The nursery bed is usually made of light steel, Fixed to the ground, The height is determined to be suitable for people to bend over and operate. It is generally 0.7 m, The width depends on the fact that people can easily operate the crops on the seedbed by bending over and extending their arms, generally taking 1.5-2.0 m; The length depends on the length and use requirements of the greenhouse. The design and application of the mobile seedbed are to improve the utilization rate of the greenhouse by sharing a road with multiple seedbeds. Its overall size is similar to that of the fixed seedbed, but it can move 60cm left and right along the width direction. Using the mobile seedbed, only one road needs to be reserved for each span in the greenhouse, thus greatly saving the use area of the greenhouse and enabling the utilization rate of the greenhouse to reach more than 80%.
