鲁西南地区冬季负积温少、早春气温回升快,冬小麦株型大,田间郁闭重,千斤高产田倒伏机率高、大面积亩产千斤以上把握性小.为探讨超500kg高产栽培新途径,实现大面积大幅度增产,我们于1996～1998年承担了山东省科委下达的重点科技攻关项目“小麦高产栽培技术体系研究”课题.经过三年努力,实现了大面积亩产600kg,1998年经山东省科委组织的专家测产验收,1000亩攻关田平均亩产622.95kg、10万亩带头田541.95kg.筛选出了亩穗数少、穗粒重高的大穗型品种为鲁西南地区亩产600kg最佳品种类型,并在系统研究其分蘖成穗规律和栽培因子的基础上,形成了一套比较成熟的、可操作性强的大穗型小麦大面积亩产600kg栽培技术体系,现介绍如下.
In the southwestern part of Shandong Province, the accumulated negative temperature in winter was low, the temperature in early spring rebounded rapidly, the winter wheat plant type was large, the field was closed and the yield was high, and the large-area mu production was less than 1000 kg. Large-scale substantial increase in production, we assumed in 1996 to 1998 the Shandong Provincial Science and Technology Commission issued a key scientific and technological project “high-yielding cultivation techniques of wheat system research project.” After three years of efforts to achieve a large area of 600kg per mu, 1998 Shandong Province Science and Technology Commission organized experts to test production and acceptance, the average per mu yield of 1000 acres of field trial 622.95kg, 100 acres of lead field 541.95kg.Screened a few acres of spikelets, spikelets large panicle varieties for the southwestern region Based on the systematical study of the rules of tillering and ear formation and cultivation factors, a set of 600kg cultivation technique system with large area and large yield per acre was formed. Now introduced as follows.
