早魁番茄是西安地区夏番茄的主栽品种,其杂交制种技术如下: 1.亲本栽培将父母本于2月中旬前后同时分别播种阳畦。用电炉丝(或地热线)加温,保持床温25～30℃。出苗40%时及时通风,以防地上茎过高。苗齐后,维持床温,白天18～28℃,夜温8～12℃,同时清洁玻璃或薄膜增强透光能力。如土壤缺水,可选晴暖时用洒壶洒水。叶片水干时,再培土0.5～0.9厘米,可保墒增温。苗子经过20天长2～3片真叶时,通风炼苗。然后将父母本苗分别移植(分苗)阳略或
Early Quebec is the main tomato variety in summer in Xi’an, the hybrid seed production techniques are as follows: 1. Parental cultivation of the parent at the same time in mid-February were seeding Yang Yang. Electric furnace wire (or hotline) heating, keep the bed temperature 25 ~ 30 ℃. 40% timely emergence of ventilation, to prevent the aboveground stems too high.
