“83—12”是江西省农科院杂交育成的晚籼新品系。1983～1984年进行了抗性和丰产性多点鉴定,1985年在我县种植1000余亩,获得高产,一般亩产700余斤,其中70亩平均亩产826斤,最高亩产达924.5斤,同年在全省区域试验中名列第二位(亩产比第一位少0.2斤)。经省农科院植保所,吉安、赣州地区农科所的抗虫、抗病性鉴定:抗褐稻虱白、背飞虱和白叶枯病。现将其栽培技术简介如下,供参考。 一、播种期 “83—12”生育期较长,在吉安市一般为128～130天,为了避免“寒露风”,安全齐穗,稳产保收。在吉安市的播种期应在6月11～13日为宜,赣北和赣中
“83-12” is a new late indica line developed by Jiangxi Academy of Agricultural Sciences. From 1983 to 1984, we carried out multi-point identification of resistance and high yield. In 1985, more than 1,000 mu of plantation was planted in our county to obtain high yield, more than 700 kg of mu per mu. The average mu yield of 70 mu was 826 kg and the highest mu yield reached 924.5 kg In the same year, the province ranked second in the regional test (mu less than the first 0.2 kg). The provincial Academy of Agricultural Sciences plant protection, Ji’an, Ganzhou Prefecture Agricultural Institute of insect resistance, resistance identification: anti-brown rice white louse, planthopper and bacterial leaf blight. Now its cultivation techniques are as follows, for reference. First, the sowing period “83-12” a longer period of growth, in Ji’an City is generally 128 to 130 days, in order to avoid the “cold dew,” safe, uniform, stable yield. The planting period in Ji’an City should be June 11 to 13, Ganbei and Ganzhong
