近几年来,由于矮缩型病毒病的危害,郊区露地秋番茄的产量逐渐降低。据了解,1983年全市平均亩产约15担,栽培面积逐渐减少,如嘉定县黄渡1978年种植面积达850多亩,1984年只种了10亩。据研究,矮缩型病毒病主要是蚜虫传毒引起的,只要在栽培上采取避蚜措施,可以大大减轻危害。目前郊区推广的中、大棚秋番茄生产,能够避蚜,一般亩产可达40担左右,但成本较高,栽培技术复杂。日本等国早有报道,利用银色、白色等地膜覆盖可以避蚜防病,国内试验证明确有一定效果。我们于1983年,应用银色膜、黑白双面膜等覆盖栽培秋番茄,取得了一定的效果,总结如下。
In recent years, due to the hazards of the dwarf virus, the output of autumn tomatoes in the suburbs has gradually decreased. It is understood that in 1983 the city’s average mu yield of about 15 Tam, cultivated area gradually reduced, such as the Yellow River in Jiading County in 1978 planted area of 850 mu, only planted 10 acres in 1984. According to the study, dwarf virus disease is caused mainly by aphid transmission, as long as the aphid measures taken in the cultivation, can greatly reduce the hazard. Currently in the suburbs to promote the production of autumn tomato production in the greenhouse, to avoid aphids, the general mu produce up to 40 or so, but the cost is higher, the cultivation technology is complex. Japan and other countries have already reported that the use of silver, white and other plastic film can be avoided aphids disease prevention, domestic test proved to have a certain effect. We in 1983, the application of silver film, black and white double-sided film covered cultivated autumn tomato, and achieved some results, summarized as follows.
