引黄灌溉对土壤质地和小麦产量影响的试验研究

Study on the effect of irrigation from the Yellow River on soil texture and wheat yield

引黄灌区农田土壤的灌溉方式主要有井灌和黄河水灌溉,相比于井水灌溉,黄河水灌溉具有土壤不易板结,水质硬度较低的特点。本文通过分析不同灌溉处理下土壤特性及小麦生长指标状况,探究不同灌溉及历时下黄河水、井水以及井黄灌溉对小麦生长的影响,研究发现利用黄河水进行灌溉对土壤容重,颗粒组成具有改良作用;冬小麦麦穗长度在8.0~9.0 cm之间,麦穗数在38~43粒内,千粒重在50~56 g之间,亩产范围在400~500 kg,其中黄河水灌溉处理数据均在高水平,且在其灌溉下可实现10%的增产效果。为引黄灌溉的实行提供数据支撑。

The irrigation methods of farmland soil in the Yellow River irrigation area mainly include well irrigation and Yellow River water irrigation.Compared with well water irrigation,Yellow River water irrigation has the characteristics of soil hardening and lower water hardness.This paper analyzes the soil characteristics and wheat growth indicators under different irrigation treatments,and explores the effects of different irrigation and duration of the Yellow River water,well water and these two water irrigation on the growth of wheat.The study found that the use of Yellow River water for irrigation has a significant effect on soil bulk density and particle composition.Improvement effect;winter wheat ear length is between 8.0~9.0 cm,the number of ears is 38~43 grain,the thousand-grain weight is between 50~56 g,and the yield per mu is 400~500 kg.The data of the Yellow River irrigation treatment are all high level,and can achieve a 10%increase in output under its irrigation.Provide data support for the implementation of irrigation from the Yellow River.
