Gloablly, the largest area of protected cultivation consists of small scale greenhouses growing crops at a low technology level. The Chinese Solar Greenhouse is a good example of such greenhouses. Also in this market, Dutch horticultural and technological knowledge can contribute substantially to an improvement of the cropping result and resource efficiency.This report describes the monitoring of the performance of a tomato crop in a Chinese Solar Greenhouse in the Shandong Province and a comparison with a similar crop in a similar greenhouse in Bleiswijk, the Netherlands. The project is carried out by a consortium consisting of Ludvig Svensson, Ridder–Hortimax, Hoogendoorn, Delphy and Wageningen University & Research, Business unit Glastuinbouw. The project was funded by the Rijksdienst Voor Ondernemend Nederland (RVO) and the Metropole region Rotterdam Den Haag (MRDH).The project has shown that also for simple greenhouses like the Chinese Solar Greenhouse the growth of the crop can be planned as a function of light availability. This analyses showed that the production is likely to be increased by 50% if the growth at the start of the cycle is accelerated. This can be achieved by earlier sowing and using white soil covering foil.
