5.78 WINE – RECOMMENDED DRIP LINES
Recommended Drip Lines
Drip irrigation provides
uniformity across years of production due to less reliance on rainfall.
However, just as important, is uniformity across the field. You do not want
uneven water and fertilizer applications where some vines receive too much
treatment, and others receive too little. For a high-quality harvest, you need
uniform application to all vines.
This is achieved through Pressure Compensating (PC) Drip Lines. When you
are on hilly place. In farms on flat plots, you use cheaper SUBSURFACE DRIP IRRIGATION
(SDI) T-TAPE.
As the diagram below shows, over a slope of five
meters, the pressure increases by 26% toward the bottom of the slope. Without a
PC drip line, the result would be that vines at the lower end of the slope
would receive 25% more water and nutrients then those at the highest elevation.
With PC drip lines, all vines receive the same water regardless of the
pressure.
It is not just sloping ground, pressure also fluctuates across blocks due
to friction of the tube. For vineyards where precision is critical, PC drip
lines are a must.
We have the widest range and highest quality pressure compensated drip
lines available. Options include cylindrical, flat and on-line drippers,
anti-siphon and no-drain options (for SUBSURFACE DRIP IRRIGATION), and a wide
range of flow rates and diameters.

SOMO LA 5.78 DIVAI – MISTARI YA KUNYESHA INAYOPENDEKEZWA
Mistari ya Kudondosha Iliyopendekezwa
Umwagiliaji kwa njia ya matone hutoa usawa katika miaka yote ya uzalishaji kutokana na utegemezi mdogo wa mvua.
Walakini, muhimu vile vile, ni usawa katika uwanja wote. Hutaki utumizi usio sawa wa maji na mbolea ambapo baadhi ya mizabibu hupokea matibabu mengi, na mingine hupokea kidogo sana. Kwa mavuno ya hali ya juu, unahitaji maombi sare kwa mizabibu yote.
Hii inafanikiwa kupitia Njia za Kutoa Fidia kwa Shinikizo (PC). Unapokuwa kwenye sehemu ya vilima. Katika mashamba ya viwanja tambarare, unatumia T-TAPE ya SUBSURFACE DRIP IRRIGATION (SDI) ya bei nafuu.
Mistari ya Matone ya PC ina vitone ambavyo kila moja ina utando wa kudhibiti mtiririko. Utando huu hulipa fidia kwa mabadiliko ya shinikizo kwenye mstari ili kila dripu itoe mtiririko wa maji uliowekwa kwa saa.
Kama mchoro ulio hapa chini unavyoonyesha, juu ya mteremko wa mita tano, shinikizo huongezeka kwa 26% kuelekea chini ya mteremko. Bila njia ya matone ya PC, matokeo yatakuwa kwamba mizabibu katika mwisho wa chini wa mteremko ingepokea 25% ya maji na virutubisho zaidi kisha zile zilizo kwenye mwinuko wa juu zaidi. Kwa mistari ya matone ya PC, mizabibu yote hupokea maji sawa bila kujali shinikizo.
Sio tu ardhi yenye mteremko, shinikizo pia hubadilika kwa vitalu kwa sababu ya msuguano wa bomba. Kwa mashamba ya mizabibu ambapo usahihi ni muhimu, mistari ya matone ya PC ni lazima.
Tuna njia pana zaidi na za ubora wa juu zilizofidia njia za matone zinazopatikana. Chaguzi ni pamoja na dripu za silinda, bapa na za mtandaoni, chaguo za kuzuia siphoni na zisizo na mifereji ya maji (kwa Umwagiliaji wa SUBSURFACE DRIP), na viwango mbalimbali vya mtiririko na vipenyo.
