在石阡县水稻生产中,粳稻品种几乎是一块空白。传统的本地品种,秆高,易倒伏,生育期长,三化螟严重,产量低而不稳,一般亩产只有四、五百斤。80年初石阡县农科所引进一些糯稻品种材料,经两年试种观察、鉴定筛选,初步确定珍珠糯为较理想的品种。其主要特征特性是:全生育期129天,株型紧凑,株高74cm,叶片浓绿直立,分蘖力强,苗期抗寒性好,抗稻瘟病,轻感纹枯病,后期转色好,平均穗长20cm左右,平均穗粒数90粒,千粒重25克,出米率76%,米质佳,糯性强,食味好。两年来,在中等肥力稻田,一般栽培条件下,亩产900斤左右。
In Shiqian rice production, the japonica variety is almost a blank. Traditional local varieties, stalk height, easy to lodging, long growth period, serious three stem borer, low yield and instability, the general mu only four or five pounds. In the early 80’s, some agricultural products of glutinous rice were introduced into the agricultural sciences of Shiqian County. After two years of trial planting and identification, the pearl waxy varieties were selected as the ideal varieties. Its main characteristics are: the whole growth period of 129 days, compact plant type, plant height 74cm, leaf green thick erect, strong tillering, cold resistance at seedling stage, blast resistance, susceptible to sheath blight, late turn good color , The average spike length of about 20cm, the average number of grains per spike 90, 1000 grain weight 25 grams, 76% of the rice rate, good quality rice, waxy, good taste. In the past two years, in moderately fertile rice fields, under normal cultivation conditions, about 900 kg per mu were produced.
