कट फ्लावर की कटाई के बाद देखभाल या हैंडलिंग कैसे करें।  In agriculture, post harvest handling is the stage of crop production immediately following harvest, including cooling, cleaning, sorting and packing. Post-harvest treatment largely determines final quality, whether a crop is sold for fresh consumption, or used as an ingredient in a processed food product. The most important goals of post-harvest handling are to keep the product cool, to avoid moisture loss and slow down undesirable chemical changes, and avoiding physical damage such as bruising. Initial post-harvest storage conditions are critical to maintain quality. Each crop has an optimum range for storage temperature and humidity. Also, certain crops cannot be effectively stored together, as unwanted chemical interactions can result. Various methods of high-speed cooling, and sophisticated refrigerated and atmosphere-controlled environments, are employed to prolong freshness, particularly in large-scale operations.  Vase Life of cut flowers:   A fresh flower is still a living specimen even though it has been cut from the plant. The vase life of cut flowers decline due to the following reasons. Inability of stems to absorb water due to blockage Excessive water loss from the cut flower A short supply of carbohydrate to support respiration Diseases Ethylene gas Room temperature and humidity Preservatives are used to extend the vase life of cut flowers. Floral preservatives are very effective in maintaining quality...

Commercial cultivation of Gerbera in polyhouse जरबैरा, जरबैरा जेम्सोनाई (gerbera), जिसे ऐस्टेरेसी कुल के अन्तर्गत श्रेणीबध्द किया गया है, दक्षिणी अफ्रिकी मूल का पौधा है। इसलिए जरबैरा को ''अफ्रिकन डेजी'' के नाम से भी जाना जाता है। यह बहुवर्षीय कर्तित पुष्प वाला पौधा है एवं कर्तित पुष्पों में इसका महत्वपूर्ण स्थान है। जरबैरा की खेती बिना पालीहाऊस के भी की जा सकती है परन्तु खुले स्थान में जरबैरा लगाने पर पौधो की अच्छी वृध्दि नहीं हो पाती जिसके परिणामस्वरूप फूलों की गुणवत्ता भी अच्छी नहीं होती और बाजार में अच्छा मूल्य नहीं मिल पाता। अत: अच्छी गुणवत्ता के फूल लेने के लिए जरबैरा को पालीहाऊस/ ग्रीनहाऊस मे ही उगाएं। पालीहाऊस एक विशिष्ट आकार की संरचना होती है, जिसको 200 से 400 माइक्रॉन मोटाई वाली पराबैंगनी विकिरणों से अवरोधी, सफेद रंग की पारदर्शी प्लास्टिक चादर से ढका जाता है। कम क्षेत्रफल में अधिकतम लाभ कमाने के लिए यह एक उत्ताम तकनीक है। हालाकिं इसमें प्रारम्भिक खर्च अधिक हैं परंतु भारत सरकार तथा राज्य सरकारों ध्दारा संचालित विभिन्न योजनाओं के माध्यम से इस दिशा में मजबूती से कदम बढ़ाए जा सकते हैं। ग्रीनहाऊस मे फूलों के उत्पादन की तकनीक भारत के लिए नई है। इसी कारण सभी इकाइयों को हालैण्ड, इजराइल तथा अन्य देशों के सहयोग से चलाया गया है। भारत में संरक्षित बागवानी की शुरूआत लगभग...

6 प्रमुख कटफ्लावर की स्वस्थ रोपण सामग्री के उत्पादन की  तकनीक Production of healthy and disease free planting material is difficult task and required lot of experience, planning and management. Since quality planting material (seed/saplings/bulbs etc.) is the basic requirement for successful flower (cut/loose) production for market or exhibition. Generally, plants are produced by two methods i.e. sexual and asexual or vegetative. In India sexual method is followed mostly in flowering annuals (seasonal flowers) and most of the shade, flowering or ornamental trees. Some annual creepers viz., Clitoria ternatea, Cobaea seandens, Lethyrus odoratus, Ipomea spp and Thunbergia alata are also produced from seeds. The other types of plants which are also commonly propagated in our country from seeds are palms, different cacti and succulents. There are several ornamentals which are not normally propagated from seeds but bred by breeders through seed to get new hybrids. Some of these plants are rose, chrysanthemum, gladiolus, carnation, orchid, dahlia, bougainvillea and hibiscus etc. Large number of ornamental plants are also produced through vegetative means like cutting, layering, buddings and asexual organs like corm, bulb and tubers. Therefore, the vegetative production technology of major cut flowers is discussed below in order to facilitate the production of quality planting material. 1. Chrysanthemum Plants are propagated by rooting terminal cuttings....

डच रोज कट फलावर की खेती कैसे करें। Floriculture is just like a fashion industry. Cultivation of cut flowers Rose, Gerbera, Carnation is profitable crop for farmers. Selection of right variety of flowers is an important tool in commercial floriculture. Battles in the international flower market can be won with producing quality of flowers, strong marketing & financial assistance so a grower should be very careful about selection of varieties.  Climatic requirement of Cut flowers:   Name of crop Commercial life cycle(Yrs) Day (0c) Night (0c) Humidity (%) Light intensity (Lux) Co2 Conc.(ppm) Rose 6.5 – 7 24-28 18.5-20 65-70 60000-70000 800-1000 Gerbera 2.5 -3  20-24 18-21 60-65 40000-50000 800-1000 Carnation 2 – 2.5 16-20 10-12 60-65 40000-50000 800-1000   Selection of cultivar: Sustainable to tropical climate: The varieties selected should be suitable for growing in tropical condition and it should have mainly excellent quality production.   Production and stem length: The varieties selected should be resistant to disease and pest. A grower should select high yielding variety in combination with high market demand and mainly varieties which have longer stem length. Colour percentage: In general roses of different colours such as red, yellow, pink, orange, white, bicolour etc are grown & sold in market. The red coloured flowers are highly preferable in markets. It is recommended to have the following mix of colors.      Colour Percentage Red 40 % Yellow 20 % Pink 20 % Orange 10 % White 10 % Steps in plantation of cut flowers (Rose, Gerbera, Carnation): Remove pebbles from the bed before plantation. Adequate moisture must be available in...
