我区由于低温、干旱、霜冻、干热风等自然灾害发生频繁,严重地威胁着春小麦高产稳产。为此我们于1973年开始进行秋施肥顶凌早播春小麦试验,收到了较好的效果。一般成熟期提早5—7天,有效地躲过了干热风的危害,增产达10%左右。6年来,经在临泽、高台、张掖、山丹等县山区地区示范推广,进一步证明秋施肥顶凌早播是一项行之有效的增产措施。一、早播小麦早生长,能充分利用生长季节。多年气象统计资料表明,在张掖的川区每年2月底至3月初有一段气温回升期,平均气温一般在0—4.5℃之
Due to frequent occurrence of natural disasters such as low temperature, drought, frost and hot and dry wind in our district, the yield and stability of spring wheat are seriously threatened. To this end, we started the autumn fertilization Lingling early spring wheat test in 1973 and received good results. Early maturity 5-7 days in general, effectively avoiding the hazards of dry hot wind, an increase of about 10%. In the past 6 years, demonstration and promotion in the mountainous areas of Linze, Gaotai, Zhangye and Shandan further proved that the autumn fertilization of Lingling early sowing is an effective stimulation measure. First, early-growing wheat early growth, can make full use of the growing season. Years of meteorological statistics show that in Zhangye Prefecture of Sichuan each year from the end of February to early March there is a period of temperature rise, the average temperature is generally 0-4.5 ℃
