赣北丘陵旱地棉花穴盘基质育苗移栽的实践

为了探讨和完善棉花穴盘基质育苗移栽在丘陵红壤旱地的相关栽培技术措施，笔者于2013年在江西省都昌县的丘陵红壤旱地进行了连片0．8hm2棉花穴盘基质育苗移栽示范。结果表明：穴盘基质苗相比营养钵苗株型紧凑、叶枝少、果枝着生节位低、开花结铃集中、增产效果明显等优势。同时总结了相应栽培技术措施。     

黄瓜的病虫害防治技术探讨

近年来,绿色食品在市场消费中受到越来越多消费者的喜爱,黄瓜在当前国民果蔬食用比例较高的食物,其种植范围广阔、品种繁多,在种植过程中病虫灾害也十分频繁。文章从伽师县地区的黄瓜种植情况出发,分析当前该地区黄瓜种植过程中存在的不足与弊端,就如何采取有效的病虫害防治手段进行深入探讨。     

新疆杏制干设备现状与发展建议

新疆是我国杏的主产区,生产的鲜杏十分适宜制干,鲜杏制干是沿承杏产业发展的有效手段。通过分析国内现有制干设备,针对设备中存在的弊端,提出杏制干设备的发展建议,为杏制干产业的发展提供参考。     

高寒地区池塘主养草鱼高效养殖技术

<正>近几年,由于草鱼市场需求量大、销售价格较高且相对稳定、养殖效益好,因此以草鱼为主养品种的养殖模式已被广大养殖户推广应用。为进一步提高草鱼的养殖产量和渔业效益,2013年昌吉州在实施农业部扶持"菜篮子"水产品生产项目的同时,在项目实施单位的两口池塘中,采用生     

南疆地区复播制干辣椒栽培试验

冬小麦收获后复播制干辣椒栽培模式能够充分利用光热资源,增加复播指数,提高效益。在喀什地区莎车县对早熟品种美国红植干椒、墨西哥甜椒、铁板椒等制干辣椒进行了育苗、果树行间麦茬后复播试验。结果表明,复播的3个早熟品种均表现出较好的产量收益,美国红植干椒表现出良好的产量潜力,辣椒素含量较高;墨西哥甜椒的单株结果数较多,单果重高,但成熟期较晚。其它两品种熟性较早。通过试验研究证明,复播制干辣椒夏季育苗移栽技术的要点主要是,适时播种、移栽,苗期气温回升时的肥水管理及病虫害管理。根据产量、品质及生育期调查结果,美国红植干椒是适于复播的最佳早熟品种,麦茬复播可充分发挥此品种生育期短、集中成熟、产量高等优良特性,可作为南疆复播制干辣椒的首选品种。     

Effects of Rice Variety and Growth Location in Cambodia on Grain Composition and Starch Structure简

The effects of variety and growth location on grain composition and starch structures were investigated using three rice (Oryza sativa L.) cultivars (Phka Romduol, Sen Pidao and IR66) with different amylose contents. All the three cultivars were planted in three different agro-climatic zones (Phnom Penh, Coastal and Plateau) of Cambodia. The protein content of polished grains increased when rice was planted at a location with higher average temperature, but their lipid content decreased. The amylose content and degree of branching were not greatly affected by the minor temperature differences among the growing locations. Starch fine structures characterized by the chain-length distribution were significantly different among the cultivars, but not significantly among different locations. The results suggested that protein and lipid biosyntheses were more sensitive to the environmental temperature than that of starch in rice grains.
