南方冬作区马铃薯增产潜力与适度规模
Yield Potential and Moderate Scale of Potato in Winter Crop Area of Southern China
摘要
Abstract
There are three favorable factors for Southern District of winter to increase potato production:①Fallow field of the area is more than 7.4×106 hm2 and Guangdong ,Guangxi ,Yunnan,Hunan four provinces have more than 1.0×106 hm2 respectively;② The three most important technical bottlenecks are related to virus-free seed potato cultivation and inspection and the relevant research is being strengthened;③Potato yield is much higher than rapeseed planting ,so some of the rapeseed chltivated land will be replaced by potato.The moderate scale of crop production is 15.178 million tons of winter potato in Southern China .In the high growth scenario,the South District will reach an appropriate scale in 2028 while in low-growth scenario ,the time is 2048. To achieve appropriate scale, around 2.5×106 hm2 to 2.8×106 hm2sown area is required. Southern District of potato in winter will yield about half the country's total output when it achieves an appropriate scale.关键词
