1979—1983连续五年研究杂交籼稻赣化2号的栽培特性及高产栽培技术,采取了以早播早栽并建立较大群体夺高产的栽培途径。从实际取得亩产850公斤的资料分析,确立高产群体主要指标:每亩最高茎蘖数40万,最大叶面积指数9—10,一生总干重1650公斤,每亩17万穗,每穗240粒,每亩总粒数4000万,结实率85%,千粒重25—26克。以及在不同条件下实现上述指标相应的看苗诊断和肥水调节的技术措施。
In 1979-1983, the cultivation characteristics and high-yielding cultivation techniques of hybrid indica Ganjiang No.2 were studied for five consecutive years. The cultivation methods of early sowing and early planting and the establishment of larger groups to seize high yield were adopted. From the actual acquisition of 850 kg per mu data analysis, the establishment of the main indicators of high-yield groups: the maximum number of tillers per acre 400,000, the maximum leaf area index of 9-10, total dry weight 1650 kg, 170,000 spikes per acre 240 Granules, the total number of grains per acre 40 million, 85% seed set, grain weight 25-26 grams. As well as in different conditions to achieve the above indicators corresponding to seedling diagnosis and fertilizer regulation of technical measures.
