大棚创建之初,主要用以栽培黄瓜、油菜等蔬菜,西红柿占用面积比例很小,特别是化隆、海西、海南、循化、海北、玉树等地很少建棚种植西红柿。市场西红柿老是供不应求。影响大棚西红柿生产的原因可能是多方面的,但不能夺得稳定优质高产是其一大障碍。为此,我们从一九七六年开始以西宁郊区为基点,探索大棚西红柿高产途径取得了一些进展,大棚西红柿产量大幅度增长:一九七六年亩产9,100斤;一九七七年12,000斤;一九七八年16,036.8斤;一九八○年17,578.9斤,对发展大棚西红柿生产起到了积极的推动作用。种植面积由七六年以前的四十多亩,发展到目前的650余亩。
The beginning of the greenhouse, mainly for the cultivation of cucumber, rapeseed and other vegetables, tomatoes occupy a small proportion of the area, especially in Hualong, Hercynian, Hainan, Xunhua, Haibei, Yushu and other places rarely planted planting tomatoes. Market tomatoes are always in short supply. The causes that affect the production of greenhouses tomatoes may be many, but can not seize the stability of high yield is a major obstacle. For this reason, we have made some progress in exploring ways to increase the yield of greenhouse tomatoes from the suburb of Xining in 1976. The yield of greenhouse tomatoes has risen sharply: 9,100 kg per mu in 1976; 12,000 kg in 1977 Kg; 16,036.8 kg in 1978; 17,578.9 kg in 1980, which has played a positive role in promoting the production of greenhouse-grown tomatoes. The acreage has grown from 40 mu before 1976 to now more than 650 mu.
