为了解决粮棉争地的矛盾,提高土地和光、温资源利用率,我省大力推行了麦棉一体化的种植方式。这种种植方式使小麦播种期比正常情况推迟15—20天,一般减产30％左右,给粮棉双丰收带来了困难。我们通过对晚播冬小麦采取播前蓄灌,冬前秸秆覆盖,春水推迟等一系列措施,使晚播冬小麦达到了亩产400—450公斤的高产水平,且比常规适播小麦少灌1—2水。具体技术措施如下: 一、选用特早熟品种。选用冀麦26号、冀麦23号等晚播不晚熟的小麦品种,这是晚播麦创高产的
In order to solve the contradiction between grain and cotton, and improve the utilization rate of land and light and temperature, our province vigorously promoted the integration of wheat and cotton. This planting method delayed the sowing period of wheat by 15-20 days compared with the normal condition and generally reduced the output by about 30%, bringing difficulties to the double harvest of grain and cotton. We adopted late sowing winter wheat by pre-sowing irrigation, winter straw cover, spring water delay and a series of measures to late-sowing winter wheat reached 400-450 kg per mu yield, and less than conventional sowing wheat irrigation 1- 2 water. Specific technical measures are as follows: First, the selection of special precocious species. Use Ji Ma 26, Ji Ma 23, etc. late-maturity not mature wheat varieties, which is a late-crop wheat high yield
