摘要
为提高小麦种植质量,验证不同耕作方式对小麦苗情素质及对小麦病虫草的影响,通过设置4种不同耕作方式处理,深翻(22 cm以上)+旋耕+播种(旋耕、施肥、播种、镇压一体机)、稻秸秆粉碎+播种(旋耕、施肥、播种、镇压一体机)、稻秸秆不粉碎+播种(旋耕、施肥、播种、镇压一体机)和稻秸秆离田+播种(旋耕、施肥、播种、镇压一体机),考察小麦苗情素质以及对小麦纹枯病、赤霉病、杂草等控制效果.结果表明,采取"深翻(22 cm以上)+旋耕+播种(旋耕、施肥、播种、镇压一体机)"耕作方式既能达到壮苗高产的目的,又能有效控制病虫草害.
Abstract
In order to improve wheat planting quality and verify the effects of different tillage methods on wheat seedling quality and wheat disease and caterpillar grass,four different tillage methods were set up.Deep turning(more than 22 cm)+rotary tillage+seed-ing(rotary tillage,fertilization,seeding,and suppression machine),rice straw crushing+seeding(rotary tillage,fertilization,seed-ing,and suppression machine),rice straw non-crushing+seeding(rotary tillage,fertilization,seeding,and suppression machine),and rice straw off the field+seeding(rotary tillage,fertilization,seeding,and suppression machine).The quality of wheat seedling and the control effect on wheat sheath blight,scab and weeds were investigated.The results showed that the cultivation method of"deep turning(above 22 cm)+rotary tillage+seeding(rotary tillage,fertilization,seeding and suppression)"could not only achieve the purpose of strong seedling and high yield,but also effectively control the damage of diseases,pests and grasses.
