不同播期、密度、土壤含水量与旱地晚花生产量的关系试验结果表明:早播能缩短生育期,减轻秋旱对花生生育的影响,提高花生从花针期起的叶面积指数和干物质积累量,增加结荚数和果重,比晚播增产率达73.8%~176.7%,达到显著水平。种植密度从目前广西大面积生产上每m2下种30粒扩大到38粒,对花生也有一定的增产作用。其主要原因是扩大了绿叶面积指数,提高了群体的净同化总量和干物质积累量,增加总结果数和总饱果数。选择低地种植,可容纳较多的雨水,保水抗旱,增产作用较明显。
The results of the relationship between sowing date, planting density, soil water content and yield of dry land late blooms showed that: early sowing can shorten the growth period, reduce the impact of autumn drought on the growth of peanut and improve the leaf area index and dry matter The accumulation of pods and fruit weight increased by 73.8% ~ 176.7% compared with that of late sowing, reaching a significant level. Planting density from the current large-scale production of Guangxi per m2 under the kind of 30 to 38 capsules, peanuts also have a certain yield. The main reason is to expand the green leaf area index, increase the population’s net assimilation and dry matter accumulation, increase the total number of fruits and total fruit number. Choose lowland planting, can accommodate more rain, water and drought, the role of increasing production more obvious.
