Ntau- ncua iav tsev cog khoom siv
Tus qauv tsim ntawm ntau-span tsev cog khoom suav nrog hom dej tshiab- txuag chaw uas tshem tawm qhov xav tau kev ywg dej, txawm tias thaum lub caij kub. Raws li cov kws tshaj lij, lub tsev xog paj zoo li no yog tus cwj pwm los ntawm kev siv loj - nplai txau, drip irrigation thiab lwm yam thev naus laus zis. Nws tsis tsuas yog ua kom lub tsev cog khoom ib txwm muaj los ntawm kev deformed lossis poob tawm, tab sis kuj ua kom cov zaub loj hlob sai hauv qhov kub thiab txias. Nyob rau hauv cov nqe lus ntawm fertilization, ib tug tshiab fertilization tshuab nrog tsawg toxicity thiab tsis muaj kuab paug tau txais yuav. Lub neej kev pab cuam ntawm multi-span greenhouses yog ntev tshaj li ntawm cov tsoos sheds. Txoj kev tswj hwm yog coj cov kev ntsuas thermal rwb thaiv tsev ua ntej kev tswj hwm. Hom kev tswj hwm tsev cog khoom no feem ntau siv qee qhov kev ntsuas thermal rwb thaiv tsev yooj yim hauv tsev cog khoom, xws li txhim kho lub scaffolding nyob rau hauv qhov tsaus ntuj, av noo thiab qhov chaw tsis zoo. Txoj kev tswj hwm yog nteg ib txheej ntawm cov yas zaj duab xis nrog lub thickness ntawm 5cm ntawm lub scaffold. Txij li cov yas zaj duab xis ua kom sov tom qab sib cuag nrog huab cua, scaffolding tsim thermal expansion, yog li tsim ib lub tsev xog paj.
Multi-span greenhouses also play a vital role in keeping vegetables growing in winter by utilizing facilities such as artificial ventilation and electricity. The design and construction of the multi-span greenhouse adopts the greenhouse in the form of multi-span. The greenhouse is mm higher than the traditional greenhouse. The greenhouse has good ventilation conditions, which is warm in winter and cool in summer. After the multi-span greenhouse is completed, natural factors such as space and terrain can be used for planting. These facilities can provide farmers with certain economic benefits. At the same time, the management of multi-span greenhouses is more scientific and standardized, and the temperature used is also higher than that of traditional greenhouses. The multi-span greenhouse can take different management methods and technical measures according to the needs, which effectively reduces the cost. The planting mode of the multi-span greenhouse is to set up a small cold storage in the greenhouse. The small cold storage is mainly to provide various biomass and trace elements needed in the greenhouse. Multi-span greenhouses occupy an important position in my country's agriculture.
Its advantages are that, on the one hand, the area of the greenhouse is greatly increased without manual operation; on the other hand, since there are many plants in the greenhouse, it can be planted and cultivated in the air. The multi-span greenhouse can not only make the growth faster and better in the greenhouse, but also make the original house built separately into intensive production and standardized management. This has created a very good condition for the development of modern agriculture in our country. The multi-span greenhouse is an ecological greenhouse with low consumption and low emission, which can not only ensure temperature stability, but also reduce the erosion of temperature on soil. This kind of eco-friendly new building materials is the first time in China. The architectural form and design style of the multi-span greenhouse all reflect the modern people's pursuit of a natural and environmentally friendly lifestyle. There is a kind of super large greenhouse, and here you can see that each room in the greenhouse has a large thermostat that can monitor the indoor air pressure and humidity in real time.
Nyob rau tib lub sijhawm, multi-span tsev cog khoom kuj muaj kev tiv thaiv hluav taws zoo, suab rwb thaiv tsev thiab lwm yam haujlwm. Nyob rau tib lub sijhawm, qhov siab ntawm qhov chaw siv tau zoo heev piv nrog cov tsoos tsev cog khoom. Yog li ntawd, multi-span tsev cog khoom yog tshwj xeeb tshaj yog haum rau sov nyob rau hauv lub caij ntuj no thiab txias nyob rau hauv lub caij ntuj sov. Cov yam ntxwv ntawm multi-span tsev cog khoom yog siv nyob rau hauv ib puag ncig ntawm sov lub caij ntuj no thiab txias lub caij ntuj sov; siv nyob rau hauv ib puag ncig ntawm lub caij ntuj sov thiab lub caij ntuj no txias; siv rau lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg. Qhov siab ntawm multi-span tsev xog paj yog ntau dua li ntawm ib txwm tsev cog khoom. Piv txwv li, nyob rau hauv cov txheej txheem ntawm kev tsim tsev cog khoom, cov hauv qab no yog siv. Thawj qhov yog los teeb tsa lub ntsuas hluav taws xob hauv tsev cog khoom. Kev saib xyuas hluav taws xob tuaj yeem saib xyuas tag nrho cov txheej txheem ntawm ntau yam kev mob hauv tsev cog khoom, thiab siv kev tswj xyuas kom zoo raws li cov yam ntxwv ntawm lub tsev cog khoom thiab nws qhov chaw ecological. Qhov thib ob yog siv cov kev pabcuam kev tswj hwm tsev cog khoom tshwj xeeb. Piv txwv li, nyob rau hauv cov txheej txheem ntawm kev tsim tsev cog khoom, cov kev tswj tshwj xeeb yog tsim raws li kev tswj hwm sib txawv. Qhov thib tsib yog siv ntau yam txuj ci. Qhov thib rau yog los teeb tsa cov neeg ua haujlwm tshwj xeeb hauv tsev cog khoom.
