甜玉米

The main varieties are: frozen sweet corn, frozen pineapple, water chestnut, mango and other products, tilapia products of shrimp, Fissidens shrimp, go head shrimp, squid, blowfish, etc. more than 20 varieties.

主要品种有：速冻甜玉米、速冻菠萝、马蹄、芒果等系列产品、罗非鱼系列产品、对虾仁、凤尾虾、去头虾、鱿鱼、河豚等20多个品种。

The results showed that the germinating rates were highest when inbred seeds of sweet corn (su 1) were harvested 25～30 days after pollination or whe n effective accumulated temperature from pollination to harv...

结果表明，发芽率最高的收获期及其有效积温分别为：普甜玉米自交系种子于授粉后的 2 5～ 30d ，授粉到收获有效积温为 4 2 7.4～ 5 2 8℃；杂交组合F1代种子于授粉后 30～ 35d ，授粉到收获有效积温为5 2 8～ 6 2 0℃。

For the poor of supersweet maize genetic resources on insect resistance, the insect-resistant varieties is not easy obtained by conventional breeding in the short time.

超甜玉米抗虫种质资源相对贫乏，本身缺少有效的抗虫基因资源，通过常规育种方法在短期内难以获得抗性品种。

In this study, based on establishment of stable and high efficient transfergenic receptor system with supersweet maize callus, the multiple insect-resistant genes were successfully co-transformed into a elite inbred line 1132 and a variety using particle bombardment and overy microinjection, and the transgenic integration, expression and inheritance were studied by means of target character and molecular biology method.

本研究在建立高效稳定基因转化受体系统的基础上，利用基因枪和子房注射两种方法将多个抗虫基因成功转化抗性较差的超甜玉米自交系及其品种，并从分子水平和目标性状上研究外源基因的转入、整合、表达与遗传规律。

By PCR amplification and southern blot analysis, the extrogenous gene with specific promoter was confirmed to integrate into the supersweet maize genome DNA with single-copy, and transformation frequency could reach as high as 9.09%.

经PCR和Southernblot分析，证明抗虫基因已经整合在超甜玉米基因组中，并且为单拷贝。T1代植株PCR检测结果表明，Bt基因能够在转基因后代中稳定遗传，基因分离符合1∶1的孟德尔遗传分离规律。

Growing sweet corn in summer could absorb redundant nutritional ingredients largely in the soil, but the number of fungi was high and the ratio of B/F is not obvious compared with CK. On the contrary, planting leafy vegetables had no obvious effect on the composing of soil microbe and the decruce of the number of pathogen of cucumber, although it could reduce the content of salty in the soil. The crop green manure of villose vetch could reduce the content of salty in the degree, but the sum of microbe in the soil reduced a little.

夏季休闲期间种植甜玉米可大量吸收土壤中多余的营养成分，但真菌数量偏高，B/F值与对照相比相差不大；种植速生叶菜虽然能降低土壤盐分含量，但对降低黄瓜致病菌数量和改善微生物区系组成方面无显著效果；豆科作物毛苕子在一定程度上降低了土壤盐分含量，但土壤微生物总量有所减少。

Effect of seed priming combined with chemical treatment on improving seed vigor of super sweet corn Zea mays L.

本文对改善超甜玉米种子活力的方法进行了探索。

The same method can be used for other Summer crops, like peppers ,sweet corn,green beans and some melons.

同样的方法可以用于其他夏季作物的种植，象是胡椒，甜玉米，绿豆和一些瓜果。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
