Je green house hufanya vizuri kwenye mazingira ya joto?
Na Eng Octavian Lasway
Back to physics from gas laws
1. Charles law ( V>T)
2. Boyle's law (P>T)
3. PV= nRT
Kutoka na eqn hapo juu tunajua kuwa V= Ah hense V>A
Wakati huo huo lazma tujue kuwa mimea kufanya transportation na unapomwagilia maji hupotea kwa njia ya mvuke na hivi vitu huchangia ongezeko la humidity kwenye hewa also increase of water molecules (joto hubebwa na molecules) na pale jua linapoongezeka huzipa molecules energy na velocity ya molecules huongezeka (collisions increase as temp increases ) collision ikiongezeka joto huongezeka Mara dufu
Pia tufahamu kuwa always cold air sink and hot air raise (ndio maana ukipanda juu ya mti husikii joto sana)
Sasa ili kupunguza joto you must suck hot air and induce cold air (fan, ac etc)
Kwenye green house tunafanyaje?
Kupunguza joto we must
1. Minimize molecules collision
2. Allowing hot air (molecules) to escape
3. Decrease UV energy that will excite molecules hence increase collision and rise temperature
Tunachofanya ni nini?
Green house zetu zina kuwa na height kubwa hii husaidia air molecules to have larger room to minimize collision
Green house zetu zina ventilation ambayo husaidia hot air to escape and cold air to enter
Green house zetu zina kuwa designed with long length being parallel to wind direction to make wind sweep away humid air
Green house zetu tunatumia shade net(55%) tunaiweka ndani kupunguza makali ya jua yanayosababisha joto kuongezeka
NB: net zina kuwa rated into % kwa sababu the percentage entails amount of dust, UV, etc that can be allowed or blocked
Mfano shade net 55% it allow 55% of UV to pass and block 45%
So we are confident with our professionalism na tumefanya kazi sehemu nyingi na green house zetu ziko bomba sana
Pia tuweze kutofautisha kati ya
1. Green house
2. High tunnels
3. Screen house
Niseme tuu kuwa kuwa watu walifanya makosa na kuharibu soko na mind za wakulima kuhusu green house
NB: picha ni green house zilizojegwa Bagamoyo na kisiwani Mafia
