田间试验于１９９４／１９９５、１９９５／１９９６年采用满播小麦、一熟棉花和麦棉两熟不同配置方式４种处理研究了共生期麦棉复合群体作物层温度分布和总积温。结果表明，不同熟制、麦棉复合群体不同配置方式作物层温度垂直和水平方向廓线不同。与一熟棉花相比，共生期５２ｄ不同群体近地面作物层日平均温度２ａ显著低，依次是：满播小麦低７．２和４．６℃ｄ－１、３—１式麦带低５．６和４．１℃ｄ－１、４—２式麦带低５．５和３．４℃ｄ－１、３—１式棉带低２．９和２．９℃ｄ－１，４—２式棉带南行低２．８和２．４℃ｄ－１、４—２式棉带北行低２．６和１．６℃ｄ－１；共生期５２ｄ近地面作物层≥１５℃积温亏缺顺序是：满播小麦群体（－３７２．９和－２４１．２℃·ｄ）＞３—１式配置（－２３１．５和－１８４．６℃·ｄ）＞４—２式配置（－１８９．２和－１２８．７℃·ｄ）。不同复合群体温度日较差大小的顺序是：一熟地（２０．６℃ｄ－１）＞４—２式北行（１９．６℃ｄ－１）＞４—２式南行（１９．１℃ｄ－１）＞３—１式（１７．９℃ｄ－１）。共生期间温度日较差达到２０℃，有利于棉花培育早壮苗，唯４－２式棉带北行棉花趋于一熟棉花。本研究揭示出麦棉复合群体的低热量胁迫?
In field experiments, the crop temperature distribution and total accumulated temperature in the co-growing cotton / cotton compound population were studied in 1994/1995 and 1995/1996 with four treatments of full-sowing wheat, cotton and cotton. The results showed that the vertical and horizontal profiles of crop temperature varied with different configurations of different cooked and wheat-cotton composite populations. Compared with a mature cotton, the daily average temperature 2a of the near-surface crop layers of different groups at the 52d symbiosis was significantly lower, followed by the low 7.2 and 4.6 ℃ d-1,3-1 wheat strata .6 and 4.1 ° C d-1,4-2 wheat strands 5.5 and 3.4 ° C lower d-1,3-1 cotton straps 2.9 and 2.9 ° C lower d-1,4 -2 cotton belt south low 2.8 and 2.4 ℃ d-1,4-2 cotton belt north low 2.6 and 1.6 ℃ d-1; symbiotic 52d near ground crop ≥ 15 ℃ The sequence of accumulated temperature loss is as follows: full-sowing wheat population (-372.9 and -241.2 ℃ · d)> 3-1 configuration (-231.5 and -184.6 ℃ · d)> 4-2 Configuration (-189.2 and -128.7 ° C · d). The order of temperature diurnal difference between different composite groups was: 20.6 ℃ d-1> 4-2 north (19.6 ℃ d-1)> 4-2 south (19.1 ° C d-1)> 3-1 (17.9 ° C d-1). The temperature difference between the symbiosis reached 20 ℃, is conducive to early cotton seedling nursery, only the 4-2 cotton belt northbound cotton tends to one paddy cotton. This study revealed low caloric stress in cotton-cotton complex population.
