为解决南方缺钙红壤旱地花生空壳问题,探明施钙与覆膜对花生干物质生产、熟相、产量构成及品质的影响,以大籽品种湘花2008和南方典型第四纪红土发育的缺钙红壤为材料,设置3个基施钙肥梯度(不施钙、施钙375 kg/hm~2、施钙750 kg/hm~2,分别标记为Ca0、Ca375、Ca750)和2种栽培方式(露地与覆膜栽培),采用土柱栽培,测定花生净光合速率、叶绿素含量(SPAD值)、熟相、干物质、产量构成因素和品质。结果表明,覆膜栽培提高了花生植株营养器官和生殖器官干物质,而施钙更好地促进了生殖器官生长,提高收获指数,降低根冠比。其中,Ca750-OF、 Ca750-PF生殖器官干物质比对照(CaO-OF)增幅达74.0%,94.3%。增施钙肥...

In order to solve the problem of unfruitful peanut pods and to explore the effect of calcium application and film mulching on the dry matter production,maturity performance,yield and quality of peanut under Ca deficiency in red soil of Southern China,large seed variety Xianghua 2008 and the typical red soil under calcium deficiency were used as material for the soil column experiment. Three calcium fertilizer gradients and two kinds of cultivation methods (open field and plastic film cultivation) were used in this experiment including no calcium (Ca0), medium calcium fertilizer (Ca375) and hig...
