Way that the study found may improve sorghum production is to reduce crop tillage.

该研究发现的第5个可以用于提高甜高粱产量的的方法就

This research studied the optimal strain combination through single strain and mixed strains fermentation from Sweet Sorghum juice. The suitable proportion and quantity of inoculation, the optimum nitrogen source and its ratio in the medium were established through mixed fermentation. The optimum pH values, fermentation time and temperature were obtained by L9 (3)3 orthogonal experiment. The optimum mixture of biotechnology fulvic acid, Azotobacter chooroccum, Phospho bacteria and Silicate bacteria were studied.

本文以甜高粱秸秆汁为原料，通过单菌及混合菌种发酵实验确定了发酵的最佳菌种组合；利用微生物混合发酵确定了发酵菌种的接种比例、接种量、最佳氮源及其添加量；用L_9(3)~3正交设计的方法，确定了发酵的最佳pH值、发酵时间和发酵温度；研究了生化黄腐酸液体肥料和圆褐固氮菌、钾细菌、磷细菌的复配工艺，并在作物上进行了田间试验。

In addition, the semichemical pulping of the stalk residue was also investigated.

此外，还对甜高粱秆渣制半化学浆进行了研究。

In China, crop strews and energy crops are the main resource of bioenergy under the condition of secure food safe. There are lots of resource of crop strew, and only the main tree food crop can produce about 0.5 billion ton strew, which can maintain soil carbon and was used as the resource of bioenergy. In addition, there are about 0.1 billion hm2 waste hills and and that is suitable for farming or forestry can be used for the development of agriculture and forestry energy.

在保证粮食安全的前提下，农作物秸秆和能源作物则是生物质能的重要原料，我国农作物秸秆资源丰富，仅三大粮食作物每年就可以产生5×10~8t左右的秸秆，除了部分还田以保持土壤碳含量外，尚有可用于生物能源的部分，此外我国尚有近1×10~8 hm~2宜农、宜林荒山荒地，可用于发展能源农业和能源林业，而且我国能源农林业物种资源非常丰富，农业主要有木薯、甘蔗、甜高粱、油菜、花生、向日葵等，林业有漆树科的黄连木，无患子科的文冠果，大戟科的小桐子，山茱萸科的光皮树等，以此为原料可以进一步加强我国的生物液体燃料等的生物质能利用方式。

The results indicated that the SS expression in sweet sorghum leaves and stems was lower at early growth stages, increased dramatically at late growth stages (flowering, grain filling, and dough stage), and reached the highest level at flowering stage.

结果表明，甜高粱叶片和茎秆中的SS蛋白质表达量在发育早期较低，发育后期（开花期、灌浆期和腊熟期）明显升高，在开花期最高。

YaJin-4: 138-day growth period in Beijing, tight ear, red shell and red grains, 340centimeters high, stem diameter of 1.95cm, succulent and sugar Brix of 21%, light leaf disease; Per-mu stalk yield of 5300kg, per-mu grain yield of 400kg.

雅4号甜高粱，北京生育期138天，纺锤形中紧穗，红壳红粒，平均株高340厘米，茎粗1.95厘米，茎秆多汁，含糖锤度21％左右，叶病轻。

The study aimed to research the molecular marker of head smut gene of sweet sorghum by RAPD technology.

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。
