Fresh-keeping sticky corn cultivation characteristics With the gradual improvement of people's living standards, fresh edible sticky corn has become a special commodity demand. The starch contained in the viscous corn is amylopectin, which is easy to form colloidal dextrin after hydrolysis, and red reaction when tested with iodine. Amylopectin is a branched polysaccharide with a small molecular weight and a branched structure, so it is sticky and sweet. Amylopectin can be dissolved in hot water at 80°C to form a viscous solution. It can be eaten softly in the mouth and sweetened in the soup. 1. Isolate the viscous maize gene (w) as a recessive trait, most afraid of mixed. Therefore, planting viscous corn must be separated from ordinary corn by at least 400 meters. Otherwise, cross-hybridization will occur due to wind or insect spread, affecting the quality of viscous corn. Segregation planting mainly adopts spatial isolation, that is, no ordinary corn can be planted within 400 meters around the planting area. This isolation is safe, and time isolation is required, so as to sow 30 days or so to avoid the flowering period meeting and cross-bred hybridization; barrier isolation, ie, villages, Mountains, forests, high stalk crops and other barriers are easy to find in the mountains. 2. The selection of high-quality, high-quality, and high-quality seed varieties is the main way to increase the market competitiveness of viscous maize. In the Fushun region, the larger areas of viscous maize planted at present are Shenjing No. 1 (grainy silvery white) and Shenshao No. 2 (grainy gold), with wide adaptability, high yield, disease resistance, high spike rate, and quality. Good advantages. This species is planted in our region, and it is 80-85 days from emergence to harvest. Generally, 1000 kg of fresh ear is produced on 667 square meters, and mulching film is harvested 10 days earlier. Food was harvested for 115 days. The plant height 220-230 cm, ear coarse 4-4.5 cm, 14-16 rows ear line, 35-40 tablets per row. 667 square meters seedling 3300-3500 strains. 20-27 days after pollination, fresh panicles were listed. 3. Advantages of increasing fattening and sticking corn like fertilizer and water are less advantageous than dent corn, need to increase fertilization material, and carefully manage digging. General 667 square meters Shi 1000 kg farmyard fertilizer and 30 kg of phosphate fertilizer as base fertilizer. Seedlings 4-5 leaf stage combined with Dingmiao for the first time spade, 667 square meters Shi 8 kg urea for attacking Miao Fei, to promote early-onset fast-growing seedlings. Seedling 8-10 leaf stage combined with the second shovel spasm, applying 15 kg of urea as a stalk manure to promote young ear differentiation. In the first week before tasseling, 10 kg of urea was applied as the attacking grain fertilizer, which promoted the fullness of the spikes, increased the yield and improved the commercial quality. 4. To increase the commercial quality of fresh ear for the sale or quick-frozen sticky corn processing, timely harvest. Generally, the harvesting period is about 25 days after silking and pollination, when the grain filling is sufficient without hardening. The fresh spikes that are harvested can be put on the market, and they can also be frozen and packaged in cold storage. The annual sales supply market.
