引进现代化温室的蔬菜高效益茬口安排探讨

ANALYSIS ON HIGH-EFFECT ARRANGEMENTS OF VEGETABLE CROP SEASONS FOR MODERN GREENHOUSES INTRODUCED IN SHANGHAI

蔬菜茬口安排是发挥温室设施先进性和获得经济效益的重要措施。在充分加热条件下，以一年一茬番茄（包括樱桃番茄）、甜椒；一年二茬或三茬“黄瓜-黄瓜”和“黄瓜-黄瓜-黄瓜”的产量和效益较好。但在调整蔬菜产品上市高峰以获得更大的经济效益上仍有潜力。在加热不充分的保温条件下，以一年二茬“番茄-甜椒”较为合理。根据实践总结，提出了上海地区现代化温室蔬菜茬口安排的四条原则。

Arrangement of vegetable crop seasons in greenhouse is an important factorfor using modern greenhouse effectively and getting good economic value. Under the condition of enough heat supply, the arrangements of one crop (tomato, cheery tomato or sweetpepper)per year and two crops (double cucumber seasons)per year and three crops (triple cucumber seasons)per year will achieve a good yield and output value, and more benefits will begot after readjusting the marketing period of vegetable products. If the greenhouse has not enough heat supply, the arrangement of two crops(tomato-sweet pepper)per year also is suitable. Based on the summarization of practices, four principles for arranging vegetable cropseasons in Shanghai modern greenhouses are suggested in this paper.
