Yexianzhan 8, a high quality conventional rice

Ye Xian Zhan 8 was bred by Guiyezhan 2 / Texianzhan 13/IR24 hybrid by Huizhou Institute of Agricultural Sciences in Guangdong Province. In 2002 and 2003, he took part in the regional test of Guangdong quality group, with an average yield of 405.91 kg per mu and 454.47 kg per mu, which increased by 9.25% and 10.64% respectively over the control variety Japonica indica 89, and the increase was extremely significant. In 2003, the average yield per mu was 446.7 kg in the provincial production test. The rice quality was identified as Grade 3 of the national standard by the Food quality Supervision, Inspection and Test Center of the Ministry of Agriculture, and the appearance quality was identified as late grade by the Guangdong Grain and Oil products quality Supervision and Inspection Station, and the disease resistance was identified as moderate resistance to rice blast, moderately susceptible to bacterial blight and moderate to cold tolerance.

Characteristic characteristic

The variety has the advantages of vigorous growth, good plant type, thick and thick leaves, narrow and straight flag leaves, good ripening color, strong lodging resistance, outstanding high yield and excellent rice quality. The main agronomic characters are as follows: the average growth period of late cropping is 110-117 days, plant height is 98.5-102.6 cm, ear length is 19.8cm, effective panicle per mu is 212000, average total grains per panicle is 127-133, seed setting rate is 78%-87.2%, 1000-grain weight is 20.2g, but it is moderate in cold tolerance and sensitive to high temperature. it is suitable to be planted sooner or later in all rice-growing areas in Guangdong Province except in northern Guangdong.

Key points of cultivation

Timely sowing, reasonable close planting and early planting should be sowed from late February to early March, before and after Qingming Festival, seedling age 30 days, late planting in the middle of July, the Beginning of Autumn moved forward, seedling age 18-20 days, sowing amount of 15,20kg per mu of seedling field, transplanting specification 20 × 17cm, field seed amount 1.5kg, leaf age 3-4 leaves, 1.7 ~ 18000 holes per mu.

Water and fertilizer management before transplanting, the field was carefully cultivated with sufficient basic fertilizer, 25 kg of calcium superphosphate and 15 kg of ternary compound fertilizer per mu. About 4 days after planting, 5 kg urea and 100 ml butachlor per mu were applied to make the seedlings grow early and quickly and prevent grass damage. The tillering promoting fertilizer was applied 8 to 10 days after planting, about 8 kg of urea and 10 kg of ternary compound fertilizer were used per mu, and Zhuanghe fertilizer was applied about 15 days after planting, and about 3 kg of urea and 5 kg of potassium chloride were used per mu. In the early stage of young panicle differentiation (i.e. in the period of returning water to the field), about 5 kg of urea and 5 kg of potassium chloride were used per mu. Before heading, according to the growth of grain seedlings, a strong tail fertilizer was applied to promote large panicles and increase seed setting rate and 1000-grain weight. In the field of water management, the mudskin was transplanted with water, tillered in shallow water, exposed to light after transplanting seedlings, irrigated with horse water once in the stage of young panicle differentiation, heading and flowering in shallow water, keeping the soil moist in the later stage, and nourishing roots and strong grains with gas.

Timely prevention and control of diseases and insect pests according to the local pest forecast, do a good job in pest control and snail control and rodent control, to ensure a high yield and harvest.
