以南京地区种植较多的“黑骠”茄子为试材,在塑料大棚里覆盖地膜进行区块试验,设计4个不同播期:11月22日、12月1日、12月21日、1月10日,并在茄子的4个不同生理成熟期测定了其植物学性状和产量,以期为南京地区茄子早春栽培的适宜时期及高产栽培提供依据。结果表明:12月21日播种的茄子在各主要生长时期如门茄成熟期、对茄成熟期、四门茄成熟期、八面风茄成熟期的株高、茎粗、最大叶面积表现都为最好,而且产量最高。
In order to test the plots of plastic film mulching in plastic greenhouse, four different sowing dates were designed: “November 22, December 1 and December 21” On January 10, the botanical traits and yield of eggplant in four different physiological stages were measured in order to provide evidence for the suitable period and high-yield cultivation of eggplant in early spring in Nanjing. The results showed that the plant height, stem diameter and maximum leaf area of eggplants planted on December 21 were significantly different in the main growth stages of solanum ripening stage, eggplant ripening stage, For the best, but the highest yield.
