<正>油菜菌核病是油菜生产中主要病害,它的发生和流行受多种因素的影响,主要受菌源、品种、气候等因素的影响,它还受栽培条件的影响,其中不同类型田油菜菌核病发生特点有差异。为了研究水田油菜和旱地油菜菌核病的发生规律,2011年~2012年我局开展了不同类型田油菜菌核病发生规律调查。

Yangliangyou 6 was used as material to study the effect of different sowing date and seeding rate on yield and yield components of no-tillage and direct seeding rice.The results showed that sowing date,seeding rate and their interaction had significant effect on rice yield.Yield reduced significantly with the postponement of sowing date.Rice yield increased till it reached the maximum yield,but decreased thereafter with the increase of seeding rate.The optimal seeding rate was different under different sowing date.Under no-tillage and direct seeding,the sowing date and seeding rate had significant effect on spikelet number per panicle,seed setting rate and effective panicle number of the rice yield components.

Systematic survey method was used to investigate impacts of different waterlogging duration at tillering stage on growth and development of the super hybrid rice and conventional rice.Disaster countermeasures of rice and key technical measures were also proposed.The yield of the super hybrid rice and conventional rice decreased with the longer duration of flooding,mainly due to reduced effective panicles,panicle and grain weight,and longer the whole growth period.Tolerance of super rice to flooding stress was stronger than that of conventional rice.Autumn planting of rice turned an important remedy in post-disaster,with timely early sowing and increased seeding rate.

介绍了武穴市2008年和2009年棉花高产创建情况,分析了武穴市棉花高产创建存在的规模不大、密度不足、施肥不当、气候异常、水利不便、效益不稳等六大突出问题,提出了发展规模生产、依托科技增产、技术革新、创新服务、整体联动、修整水利等对策。

针对武穴市温州蜜柑大面积低产、品质差、大小年严重等问题,对温州蜜柑园进行了夏季修剪.主要采用抹除夏梢、短截、回缩和环剥等夏剪方法,获得了抑制新梢徒长,促发量多质优的早秋梢结果母枝,改善通风透光条件,增进果实品质的效果;同时具有改造郁闭树和衰弱树的重要作用.

<正>SH31是由四川省农科院作物所利用棉花核不育技术选育的两系抗虫杂交棉品种,2007年武穴市(属鄂东地区)作为优质棉品种引种试验,当年每hm2子棉、皮棉产量分别为5104kg、2200kg,子棉和皮棉单产均居14个参试品种之首。2008年武穴市农业局在石佛寺镇观湖村张从斌0.17hm2棉田进行了超高产栽培

The effects of different planting methods,cultivation methods,groove width configurations on rapeseed yield and the output and economic benefits were studied with Zhongshuang No.10 as material.The results showed that the yield was impacted very significantly under different cultivation methods,groove width configurations and tillage methods.The net profit under no-tillage transplanting was the highest,under no-tillage and direct casting,but net profit under tillage transplanting was the lowest;the profit margin under the no-tillage and direct casting was the highest,the second one was under the no-tillage transplanting,the lowest one was under tillage transplanting.

武穴市农业局通过综合栽培技术措施进行鄂杂棉10号超高产栽培技术示范,2008年在鄂东地区气候异常和病虫危害发生较重的情况下,示范片平均每公顷皮棉产量2861kg,实现了超高产栽培目标,并探索出了培育壮苗、合理密植、全程化调等超高产栽培技术路线。

2008年选用杂交抗虫棉鄂杂棉10号进行超高产栽培技术示范,在鄂东地区气候条件异常和病虫为害较重的情况下,通过超高产栽培技术措施的综合应用,示范片皮棉平均单产为2 861 kg/hm2,实现了超高产栽培目标,并探索出了一条以培育壮苗、合理密植、平衡施肥、全程化调为核心技术的超高产栽培技术路线。
