番茄秋季延迟栽培,也叫二季栽培,因秋季温度下降较快,生长期短,所以后期需要覆盖保温。——培育壮苗。秋季延迟栽培的番茄,宜选用大果型早熟品种,适当晚播,避开高温季节,以减轻病毒病害。早熟品种结果集中,可提早采收,避免后期低温伤害;也可选用抗逆性强的中熟品种,适期早播。播种前先用10%磷酸三钠溶液或1～2%高锰酸钾溶液浸种半小时,捞出后用清水洗干净,置于25～30℃条件下催芽。催芽期间每天用清水冲洗种子2～3次,约70%种子露白时播种。
Tomato autumn delayed cultivation, also known as the second season cultivation, due to rapid fall in autumn temperature, short growth period, so the need to cover the late insulation. - Nurturing strong seedlings. Late autumn cultivation of tomatoes, should use large fruit type precocious varieties, appropriate evening broadcast, to avoid the hot season, in order to reduce the virus disease. Premature varieties of concentrated results, early harvest, to avoid post-cold damage; can also be used in the strong resistance of medium maturing varieties, suitable for early sowing. Before sowing with 10% trisodium phosphate solution or 1 ~ 2% potassium permanganate solution soaking for half an hour, remove and wash with water, placed in the 25 ~ 30 ℃ under the conditions of germination. During the germination period, the seeds are rinsed with water twice or three times a day, and about 70% of the seeds are sown when exposed to the white.
