本试验的目的是:通过对多效唑在西瓜生产上的应用研究,观察其对西瓜生长、产量和品质的影响。试验设在桓台县唐山镇的西瓜园。品种为“新红宝”。喷布时期分2组,即伸蔓期(5月19日)和座瓜期(5月26日)。浓度分别为100、200、300、400、500ppm 和清水对照。研究结果表明,不同时期喷施不同浓度的多效唑,对西瓜植株的营养生长的生理反应是不同的,但总的趋势是随着药液浓度的增加,瓜蔓节间缩短,叶面积变小,叶片变厚,相对的是单位叶面积上的叶绿素含量增加,光合强度提高,对产
The purpose of this experiment is: through the application of paclobutrazol in the production of watermelon to observe its effects on watermelon growth, yield and quality. Test located in Huantai Tangshan Town Watermelon Park. Variety as “new Ruby.” Spraying period divided into 2 groups, namely stretch Manchurian (May 19) and seat melon (May 26). The concentrations were 100, 200, 300, 400, 500 ppm and fresh water control, respectively. The results showed that different concentrations of paclobutrazol sprayed at different periods had different physiological responses to the vegetative growth of watermelon plants. However, the general trend was that with the increase of the liquid concentration, the melons were shortened and the leaf area became smaller. Leaf thickening, the relative unit leaf area of chlorophyll content increased, photosynthetic intensity increased, the production
