TECHNOLOGY FOCUS - BIOLOGY - Preferred Method: The method of processing the seeds involves selecting uncoated seeds by mechanical screening, drying the seeds for 2-3 days, mixing the processed seed (10 kg) with 80% tebuconazole wettable powder (10 g), and sowing the seed. The step of covering the soil of wheat production base with straw, and fertilizing the base by no-tilling involves draining the field when seeds are green such that the seeds exhibit cracks smaller than ones foot in the rice harvest, digging out primary and secondary drain in time and ditching the poorly-drained fields, harvesting rice to ground level, uniformly covering the field with rice straw, applying a decomposing inoculant (5 g/acre), or composting the field, increasing the fertilizer rate to 10-20% in the first year of zero tillage by raising both the amount of top dressing and the frequency of top dressing, sowing wheat seeds 3-5 days earlier in zero tillage than in conventional cultivation, increasing the seeding rate by 10%, contacting fertilizers and seeds with soil surface, and germinating the moisturized seeds during the drought. The step of normally growing wheat in preparatory rows involves rotating wheat, vegetables, corn, vegetables and sweet potato or soybean in over 700 meter high areas where grain crops are mainly grown in late spring in the fields to be reduced to wasteland, rain-fed fields, and dry land, in late autumn, growing a two meter wide row of wheat and a two meter wide row of vegetables or forage crops, in late spring, growing spring corn after harvesting autumn vegetables, cultivating sweet potato or soybean after the wheat harvest and planting autumn vegetables after harvesting spring corn, in the under-700-meter-high areas where the cash crops are mainly grown in late spring, rotating wheat, vegetables, peanut, vegetables, and sweet potato or soybean, in late autumn, growing a two meter wide row of wheat and a two meter wide row of vegetables or forage crops, and in late spring, growing spring peanut or spring corn after harvesting autumn vegetables, cultivating sweet potato, soybean, or peanut after the wheat harvest, and planting autumn vegetables after harvesting spring peanut or spring corn. In the method, the step of rotating wheat, vegetables, corn, vegetables and sweet potato or soybean in over 700 meter high areas is performed in October 20-25 and in under-700-meter-high areas is performed in October 25-30. The most suitable method of sowing seeds is sowing 10-12 kg of seeds in 15-18 acres, or sowing 6-7 kg of seeds in 10-13 acres, where the row spacing is 6 inch, distance between the seeds is 3 inch and the area for sowing is 33000 acres. The step of formulating fertilization recommendations involves giving preference to organic fertilizers than chemical fertilizers, harmlessly composting farmyard manure and human manure, applying (in parts): standard nitrogenous fertilizer (10), phosphate fertilizer (5) and potash fertilizer (5) per acre to obtain wheat yield of more than 400 kg/acre. The step of selecting fertilization pattern involves applying base fertilizer with nutrient content greater than 40% and nitrogen content plus minus 26%, which consists of (in kg): composted barnyard manure (1000), bio-organic fertilizer (50) and formulated fertilizer (35), applying a fertilizer for head sprouting in the jointing stage, spreading compound fertilizer (5 kg/acre), applying seed fertilizer in the full heading stage, and applying foliar spray, consisting of 90% monopotassium phosphate (100 g) and water (45 kg). The step of performing pest control involves uniformly spraying 25% propiconazole emulsifiable concentrate (30-40 ml) or 7.5% diniconazole wettable powder (20-30 g) or 20% triadimefon emulsifiable concentrate diluted with 100 ml of water (45), preventing and treating rust disease and powdery mildew during seedling stage, uniformly spraying 70% thiophanate-methyl wettable powder (100 ml) or 50% carbendazim wettable powder (70 g) with water (45 kg), preventing earing period scab, uniformly spraying 10% imidacloprid wettable powder (30 g) diluted with water (45 kg) and preventing grouting period aphid. The step of performing chemical weed control involves spraying 41% glyphosate solution (150-200 ml) 7-10 days before sowing or spraying 20% paraquat (150-200 ml) 1-3 days before sowing, ploughing the filed by no tillage, and in the pre-emergence stage, spraying 25% chlortoluron wettable powder (250 g) diluted with water (45-60 kg) to soil surface and spraying 6.9% fenoxaprop emulsifiable concentrate (50-60 ml) or 10% tribenuron-methyl wettable powder (30 g) diluted with water (45 kg). The step of storing the harvested wheat involves tedding the wheat grain in hot chamber sealed storage at low temperature and low oxygen concentration. The step of storing the harvested wheat in hot chamber sealed storage condition involves controlling moisture content of wheat grain at less than 12%, maintaining temperature of drying wheat at 50-52 degrees C for two hours, subjecting the wheat to high temperature after sealing chamber for 10-15 days, at any time maintaining the grain temperature at 40 degrees C, and storing the wheat at 50-52 degrees C.
