摘要
2010～2011年研究了3种种植密度对籽用南瓜"银辉2号"经济产量的影响。结果表明:不同种植密度对种子产量有显著影响;密度过大,田间出现徒长、叶柄脆、易折;白粉病害加重、烂果率提高、坐果指数下降;15 000株/hm2是最适宜的种植密度,产值最大,成本收益率最高。
The effect of three planting density on economic output of seed-used pumpkin ‘Yinhui No.2’ was studied in the year 2010～2011.The results showed that the seed yield were significantly influenced by planting density.When planting density was too large,the seedling was excessive growth,petioles was crisp and easily broken;powdery mildew of pumpkin was aggravated,the rate of rotten fruit would increase and fruit-bearing exponential was decline.15 000 plants/hm^2 was the suitable planting density,in this density the output value was maximum and cost-benefit was the highest.
