【摘要】 以长棒型薄皮甜瓜"薄皮脆"为试材,采用单蔓整枝,地上式砖槽基质栽培,行距90 cm,株距分别为20、25、30、35、40 cm共4个处理,研究不同种植密度对日光温室薄皮甜瓜生长发育、光合特性、果实性状、品质及产量的影响。结果表明,在行距一定的情况下,适当加大株距,有利于植株生长势增强,有利于净光合速率、果实品质和产量的提高,但过分加大株距效果不明显。在地上式砖槽基质栽培模式下,行距90 cm的情况下,单蔓整枝适宜的种植株距为35 cm。更多还原

【Abstract】 The long stick type thin melon "thin skin crispy" was used as the test material, and the single vine pruning and the above ground type brick trough were used for cultivation. The row spacing was 90 cm, and the plant spacing was 20, 25, 30, 35 and 40 cm respectively. Effects on growth, photosynthetic characteristics, fruit quality and yield of melon in solar greenhouse were studied. The results showed that when the row spacing was fixed, the appropriate increase of plant spacing was beneficial to the increase of plant growth potential, which was conducive to the improvement of net photosynthetic rate, fruit quality and yield, but the effect of excessively increasing plant spacing was not obvious. In the above ground type brick trough matrix cultivation mode, when the row spacing was 90 cm, the suitable planting distance of single vine pruning was 35 cm.更多还原
