一、旱地种植在重庆市的地位重庆市农业气候资源优越。年均温17~19℃。≥10℃积温为6000~6800℃.年总降水量1100~1300毫米,日照1243小时,占可照时数的28%,处于国内寡日照的地区之一。劳力充足,人均耕地少。1986年底止有耕地1076万亩,农业人均有地为1.01亩,全市人均0.77亩。在总耕地中旱地385万亩,占总耕地的35.8%,历来重视旱地种植.1986年旱地产粮达228.5万吨,亩平593公斤,而产量却占总产的41.5%,产值达(粮食、经作及间套蔬菜)10.2亿元,占总产值的50%以上. 重庆市旱地种植制度是逐渐发展的,到80年代初基本上普及了麦/玉/薯三熟制。最近几年发展普及粮经间套中厢分带轮作制。到1986年面积达65万亩,占适种面积的40%。
First, the status of dry land cultivation in Chongqing Chongqing agricultural climate resources are superior. The average annual temperature of 17 ~ 19 ℃. ≥10 ℃ The accumulated temperature is 6000 ~ 6800 ℃. The total annual precipitation is 1100 ~ 1300mm, sunshine 1243 hours, accounting for 28% of the available hours, in the domestic one of the areas of oligo-sunshine. Adequate labor, per capita arable land less. By the end of 1986, there were 10.76 million mu of arable land, 1.01 mu per capita for agriculture and 0.77 mu per capita in the city. Of the total cultivated land, 3.85 million hectares of dry land, accounting for 35.8% of the total cultivated land, has always placed emphasis on dry land cultivation. In 1986, dry-land grain output reached 2.285 million tons, with an average yield of 593 kg / mu and a yield of 41.5% of the total output, , Intercropping and intercropping of vegetables) amounted to 1.02 billion yuan, accounting for more than 50% of the total output value. The system of dry land cultivation in Chongqing is gradually developing. By the early 1980s, the three-crop system of wheat, jade and potato was basically popularized. In recent years, development and popularization of grain by the middle of the box set in the box system. To 1986 an area of 650000 acres, accounting for 40% of the area of suitable species.
