Mene ne lambunka naka ke bukata?
Ta hanyar Kayan Aikin Manoma za ka gani nan take, ba tare da cika fom ko jira ba, nawa ne amfanin gonarka ke bukatar ruwa, wane matakin girma ne kake ciki, da kuma wadanne na’urori masu wayo suka dace da kai.
Babu fom. Amsa nan take.
A da, sai ka tuntube mu ka jira mu mayar maka da kira. Yanzu za ka zabi irin amfanin gonarka ka ga nan take nawa ruwa kake bukata, wane matakin girma ne kake ciki, da wadanne na’urori masu wayo suka dace. Mai sauki ga karamin gonar gida, mai zurfi ga masana.
Ka lissafta bukatar ruwanka a dakika 30
Karamar gona ko gonar fure, greenhouse ko sararin bude gona: gaya mana a takaice abin da kake nomawa kuma kayan aikin zai lissafta nan take bukatar ruwanka, jadawalin ban ruwanka, tankin ajiyar ruwa, da kayan Zigbee da aka shawarta. Sauya tsakanin mai sauki da mai zurfi da dannawa daya kacal.
Bukatar ruwa na canzawa a kowane matakin girma
Karamin tsiro yana shan ruwa kadan, mafi yawa lokacin da yake fure kuma yana samar da ‘ya’ya, kuma kadan yayin da yake nunawa. Danna wani mataki ka ga abin da ke faruwa. Sauya sauyawa zuwa mai zurfi don ganin lambobin BBCH, sinadaran amfanin gona da tsarin girma.
Tushen bayanai da tushen kimiyya
Yanayin ci gaba baya amfani da ka’idojin hankali kawai, sai dai hanyoyin da aka amince da su kuma aka bincika ta hanyar takwarorinsu. A kasa akwai tushen asali ga kowane mataki na lissafi. A cikin kimiyya, abin da ake iya bibiyarsa ne kawai ke da darajar, don haka za a iya duba kowace lissafi da darajar tebur.
Bukatar ruwa tana bin ma’aunin FAO: fitowar tururin amfanin gona ETc = ETo × Kc, tare da tushen tururi bisa ga Penman-Monteith kuma, ga Netherlands, ma’aunin Makkink na KNMI. Ma’aunin ruwan kasa (TAW, RAW, tazarar ban ruwa) na fitowa daga jagorar FAO-56 din. Gishirin kasa yana bin tsarin Maas da Hoffman, jimlar zafin ta ta McMaster da Wilhelm. Ga girma karkashin gilashi muna nuni ga aikin Stanghellini.
