Aim | उद्देश्य
English
Compare shade house,polyhouse,insect-exclusion and mist/fog facilities actually available. Record what the structure controls and what it does not. Distinguish design features from measured internal conditions; a plastic cover is not evidence of a specific temperature.
हिन्दी
उपलब्ध shade,poly,insect,mist संरचना तुलना।क्या control है/नहीं लिखें।design और मापी दशा अलग;plastic cover से निश्चित ताप सिद्ध नहीं।
Inspection | निरीक्षण
English
Identify cover/mesh,ventilation,benches,water supply,nozzles,drainage and entry hygiene. Observe crop stage and placement. If permitted, measure temperature and humidity inside/outside at comparable times and locations. Do not infer long-term performance from one reading.
हिन्दी
cover/mesh,वायु,bench,जल,nozzle,निकास,entry स्वच्छता देखें।crop अवस्था-स्थान लिखें।अनुमति पर अंदर-बाहर समान समय-स्थान ताप/नमी मापें।एक reading से दीर्घकाल प्रदर्शन नहीं।
Performance | प्रदर्शन
English
Check uniform wetting,standing water,overheating,algae,crowding and disease signs. Mist reduces water loss from unrooted cuttings but excessive wetness can favour disease. Insect mesh and double-door practices can reduce entry, but monitoring and healthy source material are still needed.
हिन्दी
समान wetting,ठहरा जल,गर्मी,algae,भीड़,रोग देखें।mist सूखना घटाता पर अधिक गीलापन रोग दे सकता।mesh-entry रोकता,पर निगरानी-स्वस्थ स्रोत फिर भी जरूरी।
Record and result | रिकॉर्ड और परिणाम
English
Record structure,type of operation,control mechanism,observed/ measured conditions,advantage,limitation and proposed maintenance. Mark absent instruments as ‘not measured’. Evaluate suitability for the particular propagation stage rather than ranking all structures by cost.
हिन्दी
संरचना,कार्य,control,देखी/मापी दशा,लाभ,सीमा,maintenance लिखें।उपकरण न हो तो’मापा नहीं’।लागत नहीं,विशिष्ट अवस्था उपयुक्तता देखें।

Self-check & viva | स्वयं जाँच
Try answering before opening the answer. / पहले स्वयं उत्तर दें।
Does a mist house ensure disease-free stock? | निश्चित?
No. | नहीं।
Why inside/outside comparison? | क्यों?
To assess the observed microclimate effect. | प्रेक्षित microclimate असर देखने हेतु।
Exam answer plan: define the term, explain the mechanism, add a labelled diagram or calculation where relevant, state assumptions and limitations. / उत्तर क्रम: परिभाषा, क्रियाविधि, उपयुक्त चित्र/गणना, शर्तें और सीमाएँ।
