马铃薯免耕稻草覆盖是近年在实践基础上总结出的一项新的高产栽培技术,通过几种不同栽培方式的对比试验示范,探讨其最佳栽培模式.结果表明:免耕稻草覆盖、免耕稻草覆盖+地膜覆盖和翻耕稻草覆盖栽培模式,均较当地常规翻耕盖土栽培模式增产增效极显著,其增幅依次为155.0%、79.1%和43.4%;马铃薯免耕稻草覆盖栽培模式经济效益可观,社会、生态效益显著,市场行情看好,推广前景广阔.
为探索水稻高产创建途径,提高水稻生产效益,摸索一套适合本地区播期、密度、基本苗、施肥、水分管理和病虫害防治等技术,介绍了P88 s/747单产900kg/667m2的攻关示范表现及其栽培技术。
通过水稻产业提升行动项目的实施,加快优质高产良种的推广速度,笔者对30个水稻品种进行对比试验研究,筛选出安徽省宿松县及周边地区生产上应用的高产、优质水稻品种,为良种推广提供科学依据。
In latest 10 years, rice stalk borer population increased quickly. The analysis was performed based on the data of rice stalk borer occurred in Susong county for 30 years. And the result showed that the occurring characteristics of rice stalk borer in recent years are as the following: broad overwinter place and large bases, unidentical growth and more moth peak, long full occurred time, long damage time and serious damage at the 3rd generation. And then, the control strategies are offered as following. Conform the effect of the agriculture strategies such as decreasing the overwinter population, clearing the rice stubble, managing irrigation scientifically, and fertilizing reasonably. Control the 1st generation rice stalk borer using pestcide once in major area, and supplementary or selecting control in the serious area. Conform the control target field, controlling time and controlling index in the new situation.
