沈阳地区栽培的露地西红柿,一般在5月上中旬定植,入伏前采收结束,采收期只有20—30天。近几年来,西红柿的越夏延晚栽培引起了人们的重视,但因入伏前后多雨,以及不恰当的栽培方法,使大部分植株带病入伏,疫病和毒病发生严重,后期产量很低,影响了经济收入。针对上述情况,中日合作设施园艺试验沈阳试验场的双方技术员,精心设计了试验方案,以解决沈阳地区前期低温干旱、后期高温多雨等不良气候因子对西红柿生长所造成的影响。经1986年的试验,取得了露地西红柿亩产7,548公斤,亩产值5,283元的良好效果。现将试验中的主要栽培措施介绍如下。
Cultivation of open-field tomatoes in Shenyang, usually in mid-May planting, harvesting before the end of the harvest period of only 20-30 days. In recent years, the late-summer cultivation of tomatoes has aroused people’s attention, but because of the rain before and after entering and falling, as well as inappropriate cultivation methods, most of the plants into the sick, serious disease and disease, the late yield is very low, Affected the economic income. In view of the above, technicians from both sides of Sino-Japanese Cooperative Horticultural Experiment Shenyang Experimental Station have elaborated the experimental plan to solve the influence of the low temperature and drought in early stage of Shenyang, the high temperature and rainy later in Shenyang on the growth of tomatoes. After the 1986 test, 7,548 kg per mu of open-field tomatoes have been obtained, with a good result of 5,283 yuan per mu. Now test the main cultivation measures are as follows.
