稻田复种应用经济绿肥效应研究

The economic green manure crops, including broad bean, pea, soybean, cowpea, triticale, etc. are identified as the key manure crops suitable for growing in the paddy field in the subtropics, and the way of utilizing these crops is presented also. Additionally, five kinds of succession cropping models carried out in the paddy field, i.e. broad bean early rice late rice, pea early rice late rice, oil rape soybean late rice, oil rape cowpea late rice, and triticale early rice late rice, are studied. Finally, the economic and ecological benefits of these cropping systems are analyzed.
