| 摘 要： | １９９１～１９９４年试验表明：豫西旱区土壤含水量与自然降雨之间存在着滞后同步关系，自然降雨高峰期是每年的７、８、９三个月，而土壤含水量高峰期是每年的１０、１１、１２三个月，土壤水分变化规律呈现大、小两种循环。在冬小麦栽培中，要以争取亩穗数为主

| Abstract: | The research results in 1991￣1994 clearly indicates that the water content of soil has relationship of hysteresis and synchronization with natural rainfall in rainfed areas of West Henan. The peak period of natural rainfall is in 3 months from July to Sep. every year.The peak period of soil water content is in 3 months from Oct.to Dec.The changing laws of soil water has large circulation and small circulation in this region.It is suggested that more ear number per mu should be tryed to obtain in cultivation of winter wheat. |
