摘要/Abstract

摘要： 在江苏淮北东海县季节性干旱严重的岗岭沙土上,开展了施用保水剂和稻草覆盖对保持土壤水分和作物产量的效应的比较试验.保水剂和稻草的用量各分4级,分别为1、2、3、6g·kg^-1土和1500、3000、4500、6000kg·hm^-2.结果表明,两者均可促进小麦生长,提高当季及后茬作物产量,覆盖稻草和施用保水剂分别比对照增产小麦12.5%和10%.其作用机制在于两者均能减少土壤水分蒸发,提高土壤持水能力,增加有效水供应,并对土壤容重、温度及养分状况有一定的改善作用.

关键词: 保水剂, 稻草覆盖, 土壤水分, 作物产量

Abstract: A field experiment was carried out to study the effect of water retaining agent and straw mulch on crop yield and soil properties on sandy soil with serous seas onal drought in Donghai County,Jiangshu Province.Water retaining agent was used at four levels of 1,2,3 and 6g穔g^-1 soil,respectively,and the application rate of rice straw was 1500,3000,4500 and 6000kg穐m^-2,respectively.Resul ts showed that two approaches could stimulate the growth of wheat and increase wheat yield by 10% and 12.5%,respectively.Water retaining agent and rice straw m u lching could also prevent the evaporation of soil water,and thus improve the wat er content,bulk density,temperature and available nutrients content of the soil.

Key words: Water retaining agent, Rice straw mulch, Soil water, Wheat yield
