同期播种不同规格番茄穴盘苗定植后生长发育研究

从穴盘苗直接定植后的生长发育角度出发,系统对比了不同规格番茄穴盘苗在栽培实际中的表现。结果表明:不同规格番茄穴盘苗定植后差异较大,营养面积越小的穴盘苗直接定植后徒长现象越明显,表现在植株茎异常增粗、叶面积增大、生长点丢失等方面,营养面积越大的营养钵苗在长季节栽培中总产量最高,但72孔穴盘苗只略低于营养钵苗,营养面积较小的穴盘苗畸形果率较高,并且花期和果实成熟期延后。

Study on the Growth and Development after Different Size of Tomato Plug Seedlings Transplanted on Same Sowing Time

The cultivation performances among different size of plug tomato seedlings were compared systemically from the view of growth and development after transplanting.The results showed that the smaller size of plug seedlings had more excessive vegetative growth after directly transplanting from plug trays.It was showed abnormal thickening of stem,increases of leaves area and the loss of growing point.The larger size of nutrition pot seedlings had the most yield in the long-season cultivation but the 72-hole plug tray seedlings only slightly were less than pot seedlings;the smaller size of plug seedlings had higher rates of deformed fruit and the time of blossom and fruit ripening were delayed.
