Summary Introduction

Liangyou 1318 is a late-maturing indica medium rice variety. The plant type is compact, the plant height is moderate, the stem is thick, the tillering ability is strong, and the growth potential is prosperous. The sword leaves are long and erect, and the basal leaves are more. The panicle layer is relatively neat, with medium to large panicles and uniform grain loading. Grains long, lemma tips colorless, some grains with short apical awns. Late cooked is better. In the regional experiment, the effective spike per mu was 173000, the plant height was 124.7cm, the spike length was 25.0cm, the total number of grains per spike was 182.7, the number of solid grains per spike was 154.9, the seed setting rate was 84.8, and the 1000-grain weight was 27.30g. The whole growth period is 141.0 days, which is 3.

Details Introduction

Liangyou 1318 is a late-maturing indica medium rice variety. The plant type is compact, the plant height is moderate, the stem is thick, the tillering ability is strong, and the growth potential is prosperous. The sword leaves are long and erect, and the basal leaves are more. The panicle layer is relatively neat, with medium to large panicles and uniform grain loading. Grains long, lemma tips colorless, some grains with short apical awns. Late cooked is better. In the regional experiment, the effective spike per mu was 173000, the plant height was 124.7cm, the spike length was 25.0cm, the total number of grains per spike was 182.7, the number of solid grains per spike was 154.9, the seed setting rate was 84.8, and the 1000-grain weight was 27.30g. The whole growth period is 141.0 days, 3.7 days longer than Fengliangyou No.4. The disease was identified as rice blast comprehensive index 6.7, rice blast loss rate of the highest level 9, high susceptibility to rice blast; white leaf blight 5, moderate susceptibility to white leaf blight.
 
Source of varieties
A two-line hybrid medium rice variety was bred by Wuhan University using "Bph68S" as the female parent and "R5818" as the male parent. In 2016, it was approved by the Hubei Provincial Crop Variety Approval Committee, and the variety approval number is Eshen Rice 2016005.
 
quality yield
From 2014 to 2015, he participated in the regional test of middle-season rice varieties in Hubei province. the rice quality was determined by the food quality supervision, inspection and testing center (Wuhan) of the Ministry of agriculture. the roughness rate was 79.5, the whole refined rice rate was 63.8, the chalky grain rate was 15%, the chalkiness degree was 2.7, the amylose content was 16.0, the gel consistency was 78mm, the aspect ratio was 3.2, and the main physical and the main physical and chemical indexes reached the national standard grade ii quality standard. The average yield per mu in the two-year regional test is 668.16kg, which is 1.91 higher than that of Fengliangyou No.4. Among them, the yield per mu was 645.00kg in 2014, and the yield of Bifeng Liangyou No.4 increased by 0.76. In 2015, the yield per mu was 691.32kg, and the yield of Bifeng Liangyou No.4 increased by 3.01.
 
cultivation points
1, timely sowing, cultivate strong seedlings. Sowing in mid-April in northern Hubei, Jianghan Plain and eastern Hubei from the end of April to the beginning of May. The sowing amount per mu of seedling field is 8~10kg, and the sowing amount per mu of field is 1.0~1.5kg. Soak seeds with prochloraz before sowing. Seedling 2 leaves 1 heart period and 5~7 days before transplanting 5kg of urea per mu to cultivate multi-tiller strong seedlings.
2, timely transplanting, insert basic seedlings. Within 35 days of seedling age. The row spacing of plants is 16.7cm by 26.7cm, 2 grain seedlings are planted in each hole, and about 80000 basic seedlings are planted per mu.
3, scientific management of fertilizer and water. Heavy application of base fertilizer, early application of top dressing, skillful application of ear fertilizer, appropriate application of potassium, calcium, silicon, zinc, boron fertilizer, generally 10~12.5kg of pure nitrogen per mu. Transplanting seedlings in shallow water, turning green with inch of water, promoting tillers with thin water, gradually drying the field to prevent lodging 20-25 days after transplanting seedlings depending on the condition of the seedlings, maintaining shallow water layer from booting to heading stage, filling enough water after full spike, and drying, wetting and drying in the later stage.
4. Pest and disease control. Focus on the prevention and control of rice blast, pay attention to the prevention and control of sheath blight, bacterial streak disease, white leaf blight, rice false smut, rice grain black powder, stem borer, rice planthopper and other diseases and insect pests.
 
suitable range
It is suitable for middle rice cultivation in areas outside the southwest of Hubei Province, but it is not suitable for planting in areas where rice blast is common and recurrent.
