Shengli black glutinous rice

The variety was selected by Shengli Oilfield Underground Agriculture, Industry and Agriculture Company and Dongying seed Management Station using China 91 as female parent and Xiangxuenuo as male parent.

The growth period of this variety is about 165 days in the Yellow River Delta; the plant height is about 1m, the plant type is compact, the leaf color is dark green, the flag leaf is longer, and the coleoptile tip, ligule, leaf tip and subpanicle internodes are all purple. Panicle color, green at the beginning of heading, purple after grain filling, light brown glume after maturity; 2O~23cm of panicle length, 110 grains per spike, seed setting rate 85%, 1000-grain weight 26g, seed coat black and shiny; strong tillering ability, lodging resistance, salt-alkali resistance, rice blast resistance, light sheath blight; brown rice is an ideal black health food with high nutritional value. According to the determination of the central laboratory of Shandong Academy of Agricultural Sciences, the crude protein content is 8.36%, the crude fat content is 1.68%, and the ash content is 1.28%. Vitamin B1 and B2 contain 0.31mg per 100g (2.8 times that of common varieties), 0.16mg Zn and Fe per 1kg content 23.5mg, 116.Omg (2.1times and 20 times that of common varieties), and phosphorus content reaches 0.27% (more than 40 times that of common varieties). The total content of 11 amino acids reached 7.83%, 40% higher than ordinary varieties; straw and Yingliang are rich in pigments and are good raw materials for extracting natural pigments.

In 1993, he participated in the regional trial of rice varieties in Dongying City, with an average per unit yield of 550.8kg, ranking first among the 14 tested varieties, 3.1% higher than the control China 91 and 30.0% higher than Xiangxuenuo; in 1994, the production demonstration in the middle and high fertilizer and water plots showed an average per unit yield of 539kg; in 1997 96.7hm2, the average per unit yield was 510kg. In the regional trial of special rice in Shandong Province from 1998 to 1999, the average yield per mu was 14.1% higher than that of Jingyin 119, and the average yield per mu in 1999 production test was 578.5kg, 11.3% higher than that of the control.

Region and technology 1. It is appropriate to raise seedlings at the right time. Before falling into the valley, do a good job of seed treatment. The seedlings were raised in the middle and last ten days of April, the seedling age was 28-35 days, and the seedlings were planted around May 25. Dry cultivation and sparse planting can be postponed appropriately. two。 Reasonable density. There are about 50 000 basic seedlings per mu, row spacing 25~30cm, hole spacing 12~15cm, the maximum number of tillers is about 300000, and the number of panicles per mu is about 250000 ears. 3. Fertilizer and water regulation. When applying sufficient base fertilizer, high quality soil fertilizer 3~4m3 and calcium superphosphate 5Okg can be used per mu. According to the growth situation, topdressing urea 25~4Okg per mu, tillering fertilizer, panicle fertilizer and grain fertilizer were applied at the ratio of 2:2:1. Pay attention to potash fertilizer, generally apply potash fertilizer 2~5kg per mu, half in seedling stage and half in young panicle differentiation stage; water management, in line with the principle of "front promotion, middle control and post protection", achieve shallow deep protection, shallow tillering, dry and wet control seedlings, water pregnant, heading and flowering, wet grouting. 4. Timely control of rice planthopper, rice stem borer and sheath blight.
