摘要
以打瓜为试材,研究播种密度对打瓜产量和相关生理参数的影响。结果表明:播种密度对产量、干物质积累、主要经济性状、叶面积指数、光合势都有着显著的影响。其中58 140株/hm2处理产量和干物质最高,单瓜经济性状没有达到最佳值,仍具有增产潜力。以46 515株/hm2产量居中,单瓜经济性状量高,但增产空间较小。
The effects of seeding density on yield and physiological of watermelon was researched using watermelon as test material.The results showed that density had an important influence on yield,dry matter,major economic characters,LAI and population leaf area duration.The highest yield and dry matter,lowest major economic characters were obtained when the seeding density was 58 140 plant/hm2,and it still had potential to improve yield.46 515 plant/hm2 obtained highest economic characters but lower yield,it had litter potential to improve yield.
