套作

The study of mechanical interplanting of corn and lucern carried out in 1981—1985 has provided a good way to develop corn and lucern production on a large scale in Xinjiang.

1981—1985年进行的玉米与苜蓿机械化套作栽培的研究，为新疆大力发展玉米、苜蓿生产提供了一条良好的途径。

Interplanting with rounds oftreatment, In contrast can not provide a good soil microbial environment for crops.

小麦、大豆轮作和毛葱套作都可以为作物创造一个适合生长的良好的微生物环境。

Rotate and Interplanting have effects on cucumber photosynthesis.

不同轮套作作物对黄瓜的光合作用有一定影响。

Therefore, programs aimed to correct aforementioned shortcomings were initiated, including educational training, formularizing the standard procedure of nursing guide of chemotherapy, establishing a set of completed assessment tool of performance and evaluation, and designing a set of varieties of supplement-assisted health education. The results showed that the quality was much satisfied.

经由举办执行化学治疗护理指导之教育训练，制定执行化学治疗护理指导之標准与指引单、规划一套完善的化学治疗护理指导执行与评值规范，以及製作一套完整且多样化的护理指导辅助工具等改善办法，並对护理人员及病患作结果检测。

In addition, mathematical models describing the changes of soil water contents with time within 30 cm, 60 cm, and 90 cm depth were also proposed, with which the temporal dynamics of soil water in the intercropped maize fields could be well predicted.

并建立了0～30、30～60、60～90及0～90cm土层土壤含水量随时间变化的数学模型，以此来预测试验条件下套作玉米带土壤水分随时间变化的动态。

In the future the 10 million acres of orange orchard base construction, reasonable technology will be equipped grants rich farmers to play a bigger role.

在今后的全县10万亩柑桔基地建设中，果园合理间套作技术将会为助农致富发挥更大的作用。

2 Effects on yield and quality In relay-planting system, increase the quantity of nitrogen application could increase the yield and quality of spring-sown maize and summer-sown maize.

3.2 不同施氮水平产量和品质差异对套作来说，增施氮肥使全年产量提高、品质改善，这得益于春、夏玉米的协调，但是产量的阈值要高于品质阈值。

At the same time, there were complementation of water and nitrogen between spring-sown maize and summer-sown maize in the system of relay-planting. Spring-sown maize could get water and nitrogen from the summer-sown maize zone, and also the roots of summer-sown maize could touched to the regions of spring-sown maize to get water and nitrogen.

同时，套作体系中春、夏玉米存在对氮素和水分的互补利用，春玉米根系可以伸展到夏玉米区，而夏玉米也可以吸收利用春玉米区，从而达到养分与水分的互补利用。

Relay-planted with the same spring-sown maize, the quantity of nitrogen absorption of late maturity summer-sown maize was highest, but their nitrogen use efficiency was lowest, which because most the nitrogen absorbed were left in organs except grain.

与同一春玉米品种套作时，夏玉米为晚熟品种的吸氮量均较高，但其氮利用效率却较低，所吸收的氮更多的滞留在籽粒以外的植株器官中，向籽粒中转移的较少。

4 Mechanisms of the effects on yield and quality With the application of nitrogen, the chlorophyll content, NRase activity, photosynthesis rate, fluorescence parameters in the ear leaves of spring-sown maize and summer-sown maize were affected dramatically, which could affect the yield and quality of maize.

3.4 不同施氮水平产量和品质差异的生理学基础春夏玉米套作时，施氮处理显著影响春、夏玉米穗位叶叶绿素含量、硝酸还原酶活性、光合速率、荧光参数等，从而影响产量和品质。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
