摘要
1997~ 1999年在蒙自县草坝镇对水田、旱地的多种种植模式进行比较研究 ,指出在云南南亚热带气候类型地区种植模式安排的基本原则 :水田大春雨养种植为主 ,着重粮食生产 ,小春灌溉种植为主 ,种植经济作物 ,着重于经济效益 ;旱地大春雨养种植 ,以获取经济效益为主 ,小春采用节水栽培 ,着重生产粮食。中稻—大棚辣椒、中稻—冬玉米间黄豆、中稻—秋洋芋—冬玉米 (鲜食 )是水田的较好模式 。
From 1997 to 1999, a number of crop systems for rice field and nonirrigated farmland of south subtropical region were studied at Caoba in Mengzi county. Some basal principals of selecting crop system for south subtropical region are as follow:(1) At rice field, summer crops are irrigated mainly by nature rain and cultivated for the purpose of producing grain, however, winter crops are irrigated with store water and planted industry crop for the purpose of abtaining money. (2) At nonirrigated farmland, some crops are watered by nature rain and planted with the purpose of obtaining money, but winter crops are planted with using the technology of saving water and harvest grain. After comparing the economical profit and yield of many crop systems, we found that the better crop systems for rice field include mid rice-glasshouse pepper, mid rice-winter maize intercroping soybean, mid rice-autumn potato-winter corn (fresh food), but tabacco-winter is the best crop system for nonirrigated farmland.
