【摘要】 本文定量地研究了6种密度(2,3,4,5,6,8株/m~2)与大棚黄瓜各产量形成因素的关系。结果表明,黄瓜密度分别为4.54株/m~2和6株/m~2时,产量和产值最高。更多还原

【Abstract】 The effects of planting density of 2 to 8 plants per square metre on yield of greenhouse cucumber were studied. Results showed that mean leaf area, dry matter weight and fruit yield of a slagle plant negatively correlated to planting density, while total dry matter weight, early yield and fruig number positively correlated with it. The best yield and grossout-put value were achieved at the densities of 4.54 plants/m~2 and 6 plants/m~2 respectively.更多还原
