Analysis on surge flow ditch irrigation technique in mountain area 丘陵山区波涌沟灌技术要素分析
2.
Plastic mulching effects on potato under drip irrigation and furrow irrigation 滴灌与沟灌马铃薯覆膜效应研究
3.
Furrow irrigation is a common way used in wide - row crops 沟灌是大田宽行作物灌溉中比较常见的一种灌水方式。
4.
But conventional furrow irrigation is difficult to meet the demands that crops are irrigated at proper time and with suitable amount of water 但常规沟灌很难满足灌溉过程中对灌水适时、适量的要求。
5.
Comparison of the characteristics of soil biological in sea - island cotton field between drip irrigation under mulch and furrow irrigation in tarim reclamation area 膜下滴灌与沟灌海岛棉田土壤微生物特性的比较
6.
With the inner container ' s application of german teflon tube , it is adhesive - resistant and high - temperature resistance ( can arrive 250 ) with excellent flexbility , and eliminates charring 沟灌内壁采用特氟龙材料，具有良好的柔韧性、防粘性及耐高温性（最高可达250摄氏度） ，级大减少了胶的炭化现象。
7.
In the third chapter , the ratio of soil evaporation to crop transpiration under different furrow irrigation ways adopted in summer maize field was analyzed by using the measured data in lysimeters 与固定隔沟灌相比，交替隔沟灌土沟的干湿交替循环不会使根区部分土壤出现长期极度干燥的情况，因此对作物根系的生长和吸收比较有利。
8.
In the fourth chapter , the effect of controlled alternative furrow irrigation on the ratio of root to shoot , filling rate , leaf physiological indexes , yield and water use efficiency of summer maize were discussed , and the lower limits of suitable irrigation for summer maize in controlled alternate furrow irrigation were analyzed and determined 29 ，表明干湿交替循环不仅可以减少每次灌水间隔期间的棵间土壤无效蒸发，而且也抑制了作物的奢侈蒸腾，因此作物需水量明显减少，节水效果非常显著，被证明是沟灌方式中最科学的一种灌水方法。

In the first chapter , the improvement and development of furrow irrigation technique , theory foundation of controlled alternate furrow irrigation , and related research advance at home and abroad were analyzed and elucidated , and the main problems needing to be studied further and to be solved were put forward . in the second chapter , the soil infiltrative parameters , irrigating water advancing and water redistribution in soil were studied by adopting the controlled alternative furrow irrigation in field 根据建立的水量平衡方程，采用模式搜索技术中的爬山法，利用infiltvs分析软件，计算得到的不同沟灌方式灌溉水流的推进过程与利用实测资料回归分析得到的水流推进过程几乎完全重合，预测精度很高，因此证明本文建立的模型和分析计算方法是合理可行的，完全可用于不同沟灌方式土壤入渗参数和水流推进过程的估算。
10.
In order to decrease expenditure and increase total economic efficiency , the key technique consisted of a complete sets of base fertilizer heavily , stabilizing n , increasing p and k , herbicide , coordinating of irrigation , fertilization and dpc regulation in first - flowering time , water - saving by furrow irrigation , simple pruning of cotton plants , chemical accelerating the ripening and so on 以重施基肥，稳氮增磷增钾，化学除草，初花期水、肥、控同步，沟灌节水，简化整枝及化学催熟等项技术组装配套，达到节支省工，提高整体经济效益。
