一、品种选择 秋延后栽培,苗期气温高,而结果期气温低,故应选用耐热且抗寒、抗病的丰产品种。常用品种有毛粉802、佳粉15、佳粉10号等。 二、培育壮苗 1.确定播期 播期可据定植期推算得知。秋茬番茄苗龄不宜过长,一般20～25天即可,苗具6～7片叶时定植。华北地区一般在7月中下旬～8月上旬播种。 2.准备苗床 育苗正值高温多雨季节,易感病和徒长,故应选地势高、排水好的地块,做畦宽1.6米,畦上搭棚遮荫防雨。
First, the choice of autumn planting after planting, seedling temperature is high, but the results of low temperature, it should be used heat and cold, disease-resistant varieties. Usual varieties have rough 802, flour 15, flour 10 and so on. Second, nurturing strong seedlings 1. To determine the sowing date sowing according to planting projections.

Preparing seedbed Nursing positive hot and rainy season, susceptible to illness and leggy, it should be elected high potential, drainage of good plots, do 畦 wide 1.6 meters, 畦 scaffolding shelter rain.
