福建春播覆膜花生生长发育特性及栽培技术

用白皮1号和泉花10号分别在红黄壤旱地的中低肥力和中等肥力水平土壤进行覆膜栽培试验，并对其整个生长发育进程进行观察和取样分析，最后进行考种和测产，试验表明，花生覆膜栽培出苗早，生长快、出苗率高，明显促进前期茎枝和叶片生长，使分枝数增多，叶面积系数和净同化率提高，提早开花，增加开花量，并使花生的整个生育期提前，覆膜花生果多果重，增产显著（达24.1%-34.1%)，表明覆膜栽培适合南方普及推广，并提出了覆膜栽培的技术要点。

Growth Characters and Cultivation Technologies of Polythene Mulched Spring Peanut in Fujian

Polythene mulched cultivation experiments were carried out in red and yellow soil arid farmland with lower than average fertility and medium fertility level using 2 peanut varieties, Baipi No.1 and Quanhua No.10.Careful observation and sample analysis were taken in whole growth courses, and botanical characters and yield data were recorded at/after harvest. The result showed that polythene mulched cultivation enabled peanut to emerge earlier, grow faster, and resulted in a higher emergency rate. This method accelerated vegetative growth at early stage obviously, increased the number of branches per plant, enhanced leaf area index and net assimilation rate, and caused early initiation of flowering stage, more flowers, a shortened duration, higher pod weight and more pods per plant, and significant yield increases (24.1%-34.1%). This method fits to be widely extended in Southern China. Some main cultivation points were put forward in the paper.
