Hi-tech firms sowing seeds of future profits
But it may take years for those diversifying into farming to reap rewards

Technology firms and other companies on the mainland venturing into agriculture might have to wait years to develop their expertise and turn strong profits, according to analysts.
The bottled water producer Nongfu Spring is one of the latest firms to diversify into agriculture, setting up a business to sell oranges online.
It follows in the footsteps of companies such as the computer maker Lenovo and the internet firm NetEase who have set up farming subsidiaries.
Others who have stepped into the market include the property developers Evergrande and Wanda, and IT firms Qihoo 360 and Alibaba.
Analysts have suggested that companies are tempted to venture into agriculture because of public unease about the quality of much of the food made on the mainland after a series of safety scandals.
Newcomers felt they can offer a fresh approach and give consumers greater quality, analysts said.
