Y Liangyou 7 is the third generation of new super hybrid rice varieties under the auspices of the National “863†Key Project “Creation and Application of Strong Advantage Rice Hybrids†that was independently sponsored by Academician Yuan Longping. The hybrid rice research center in Hunan Province has used the bio-molecular technology to produce a new hybrid rice combination with super high yield. The cultivar is a new combination of super rice introduced from Yuanyouping Super Hybrid Rice Y You 1. Due to the high yield and resistance genes of rice, the variety has higher potential for yield increase, higher yield, better rice quality, stronger resistance, and larger ear. In Hunan, Hubei, Jiangsu, Anhui, Sichuan, Zhejiang, Fujian and other places are planted.
I. Characteristics of the variety The whole growth period of the combination is 135 days, and the age of the aphid is about 30 days. Moderately loose plant type, flag leaf upright, plant height about 110 cm, long grain, aspect ratio 3:0, main stem leaves number 16 leaves, strong tillering power, vigorous growth, dark green leaves, maximum seedlings per acre 300,000 spikes of 183,000 spikes. The tip of the leaf sheath was colorless, awnless, with a head length of 26.5 cm and a total of 217 grains per panicle. The seed setting rate was 88% and the grain weight was 27 g. The main indicators of rice quality: brown rice rate 79.2%, polished rice rate 73.1%, the rate of whole polished rice 68.7%, grain length 7.0 mm, chalky grain rate 29.6%, chalkiness 3.1%, transparency grade 1, amylose content 15%, Moisture 11.7%, excellent appearance quality, good taste.
Second, the variety performance (1) production. The variety has a typical super-high rice canopy, spikelet type plant morphology, high yield. In 2008, it took part in the national trial of the middle and lower reaches of the Yangtze River, with an average yield of 750 kilograms. In 2009 in Hunan Liuyang, Taoyuan, Anhui Wuhu, Hefei, and Jiangsu Huai'an, Jiangxi De'an, Wuyi, Zhejiang, Jingzhou, Hubei and other places demonstration planting, more than 800 kg per mu. (2) Resistance. The varieties have developed roots, thick stems, strong drought resistance, high temperature resistance, and resistance to fertilizer and lodging. Identification of Rice Blast Resistance: Leafhopper Grade 3, Comprehensive Evaluation of Rice Blast. 4.
Third, cultivation techniques (1) timely sowing, nurturing strong. The suitable sowing date is in early April each year. The sowing amount per hectare is 8 to 10 kilograms, and the amount per hectare of farmland used is 0.5 to 0.75 kilograms, and the ratio of farmland to farmland is 1:7. Basal fertilizer applies 30 kg of compound fertilizer per acre, 5 kg of urea per acre is used as weaning fertilizer, 4 kg of urea per acre is transplanted for 4~6 days before transplanting, and is transplanted before 5 leaves. Timely control of pests and diseases such as rice, thrips and horses. (2) Proper close planting and cultivation of strong seedlings. Planting 13500 holes per acre and planting 40,000 to 50,000 basic seedlings should be planted and planted directly. Timely control of seedlings, drying up to 165,000 seedlings per acre. (3)Formulation, balanced fertilization, balanced growth. Reapply basal fertilizer, apply 700 kg of organic fertilizer and 30 kg of compound fertilizer per acre as basic fertilizer; apply early-stage sub-fertilizer, transplant about 5 days per mu of compound fertilizer 10 kg and urea 5 kg; apply panicle fertilizer, in the young ear In the second and third stages of differentiation, seedlings are immediately topdressed with 3 kg of urea per acre and 10 kg of potassium chloride; clever foliar fertilizers are used, when the first ear and full panicle are sprayed with 250 ml of green leaves per acre, and the filling period is one acre. Use Bijing 5 grams to spray 20 kilograms of water on the surface to increase the seed setting rate and 1000-grain weight. (4) Scientific management and thin water irrigation. (5) Strengthen integrated pest management. Pay attention to the control of aphids and sheath blight, rice blast, etc., and reduce the occurrence of rice planthoppers. From breakage to full heading stage, attention should be paid to the control of rice smut, sheath blight, panicle blast, aphids, and rice planthoppers.
