黑龙江省农产品深加工产业发展现状与对策

黑龙江省的农产品加工体系已经初步形成，但农业发展主要依赖于“原”字号产品。阐述了黑龙省农产品深加工产业建设存在的问题，通过分析制约农产品深加工产业发展的主要原因，从优化种植结构、整合现有资源、拓宽农产品销路以及提高农产品附加值4个方面提出解决对策。旨在做强食品加工业，上调农产品利润空间，通过“大龙头、大链条、大产业、大品牌的高效农业全产业链”促进粗放农产品向高附加值产品的转变，努力实现从产粮大省到农业强省的新跨越。      

Leaf carbohydrates assimilation and metabolism affect seed yield of rapeseed with different waterlogging tolerance under the interactive effects of nitrogen and waterlogging

Waterlogging is a main factor causing rapeseed (Brassica napus L.) yield loss, and reasonable nitrogen (N) applications can compensate for this loss. To investigate the effects of N rates on seed yield of waterlogged rapeseed, the waterlogging-tolerant rapeseed variety ZS 9 and sensitive variety GH01 were waterlogged for 0 and 10 days with five leaves at the seedling stage under four N rates (0, 90, 180 and 270 kg/ha). Waterlogging significantly decreased seed yield, while N application can alleviate the yield loss. The yield decrease rate of waterlogged GH01 was greater than that of ZS 9 under the same N rate. During the seedling and bolting stage, the leaf photosynthetic rate (Pn) and ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) activity increased, while activities of adenosine diphosphate glucose pyrophosphorylase (AGPase), sucrose synthase (SuSy) and sucrose phosphate synthase (SPS) decreased with more N under the same watering conditions. Compared to the plants without waterlogging, the leaf Pn and Rubisco activity, starch and sucrose contents of waterlogged rapeseed decreased at the two stages; activities of AGPase, SuSy and SPS of waterlogged rapeseed decreased at the seedling while increased at the bolting stage for both the two varieties. At the flowering stage, the Pn, the activities of Rubisco, AGPase, SuSy, SPS and contents of sucrose, starch increased with more N application for both ZS 9 and GH01. Compared to the plants without waterlogging, the Pn and Rubisco activity for waterlogged plants of the two varieties increased; the waterlogged plants of tolerant variety had higher activities of AGPase, SuSy and SPS, while those of sensitive variety was significantly lower. However, the decreased starch and sucrose content were found in both tolerant and sensitive varieties. The activities of AGPase, SuSy and SPS at flowering were highly positively correlated with yield under the interactive effects of N and waterlogging. These results suggested that the flowering stage is the most important stage that N had the positive regulation on waterlogged rapeseed growth. The carbohydrates translocation from leaves to seeds of the tolerant variety were enhanced after waterlogging, while that of the sensitive variety was still inhibited. This was the main reason for the difference in yield between the two waterlogged varieties.

川西北地区上二叠统吴家坪组凝灰岩分布地震预测

通过对川西北地区的老井进行复查,发现多口井在上二叠统吴家坪组存在大套的凝灰岩,对上述井的地质、测井、地震资料综合分析发现,凝灰岩的岩性以凝灰质泥岩、凝灰质粉砂岩、凝灰质灰岩、沉凝灰岩、凝灰岩、凝灰质白云岩为主,次生溶蚀孔隙发育;凝灰岩在测井曲线和地震剖面上均有明显的响应特征:在测井曲线上表现为明显的低纵波速度、高自然伽马特征,凝灰岩底界在地震剖面上均表现为波峰反射特征.为此,采用模型正演分析技术及波阻抗反演技术,首次对四川盆地川西北地区晚二叠世吴家坪组凝灰岩的分布进行了地震预测:双鱼石构造-剑阁区块的北部地区凝灰岩分布最厚,南部减薄;双鱼石构造东部凝灰岩分布较厚,西部减薄,直至不发育.研究结果表明,晚二叠世吴家坪组在川西北地区沉积了一套凝灰岩,从西北至东南方向减薄;由于凝灰岩物性好,孔隙度高,可成为四川盆地火山岩气藏勘探全新的后备领域,为川西北地区下一步新的勘探领域开发提供了重要研究基础.
