南京地区露地秋番茄产量低而不稳,除受品种影响外,与播期和苗龄也有较大的关系。为了有效地提高单产,在1983年露地秋番茄试验基础上,1984年又进行了该项试验。 一、材料与方法 试验在本所科研基点进行,品种为中熟品种苏抗5号和早熟品种苏抗6号。苏抗5号播期分别为7月10日、20日和29日,每一播期分3次移栽,苗龄分别为28天、34天和40天;苏抗6号播期为7月17日、21日和29日,同样分三次移栽,苗龄分别为21天、27天和33天。采用8厘米直径的营养钵育苗,定植密度每亩4000株,田间小区面积为57.4平方米,顺序排列,重复两次。另设采样区,田间管理水平一般。
Nanjing open-field autumn tomato yield is low and unstable, in addition to the impact of varieties, and sowing and seedling age also have a greater relationship. In order to effectively improve yield, based on the autumn field tomato test in 1983, this trial was conducted in 1984. First, the material and method test carried out in our research base, the varieties of medium-resistant varieties Sukang 5 and early varieties Sukang 6. Sukang 5 sowing date were July 10, 20 and 29, each sowing three times transplanting, seedling age were 28 days, 34 days and 40 days; Sukang 6 sowing date of 7 On the 17th, 21st and 29th, the same transplanting was carried out in three times. The seedlings were 21 days, 27 days and 33 days respectively. 8 cm diameter nutrition bowl nursery, planting density of 4000 per acre, field area of 57.4 square meters, arranged in order, repeated twice. Another set of sampling area, field management level in general.
