解釋
壠田-
Comparison of the characteristics of soil biological in sea - island cotton field between drip irrigation under mulch and furrow irrigation in tarim reclamation area
膜下滴灌與溝灌海島棉田土壤微生物特性的比較 -
Aimed at the landform and the shortage of water resource in hilly mountain areas, the field experiments of surge furrow irrigation and continuous irrigation were carried out
本文針對丘陵山區地形和水資源短缺等特點，採用正交試驗設計進行波涌灌和連續灌田間試驗。 -
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
與固定隔溝灌相比，交替隔溝灌土溝的干濕交替循環不會使根區部分土壤出現長期極度乾燥的情況，因此對作物根系的生長和吸收比較有利。 -
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
根據建立的水量平衡方程，採用模式搜索技術中的爬山法，利用infiltvs分析軟體，計算得到的不同溝灌方式灌溉水流的推進過程與利用實測資料回歸分析得到的水流推進過程幾乎完全重合，預測精度很高，因此證明本文建立的模型和分析計算方法是合理可行的，完全可用於不同溝灌方式土壤入滲參數和水流推進過程的估算。 -
At present, the studies about the controlled alternate furrow irrigation are focused on how it affects the water physiological indexes, water consumption and yields of crops. but, some problems suc h as the soil infiltrative parameters, irrigating water advancing, water redistribution in soil, calculation of crop water requirement and water consumption, and the upper and lower limit indexes of soil moisture, guiding a field irrigation after the controlled alternative furrow irrigation is implemented in field, have not been researched systematically and deeply. if these problems could not been solved commendably, the popularization of controlled alternate furrow irrigation will be affected
然而，目前有關交替隔溝灌溉的研究還主要集中於這種灌水方式對作物水分生理指標、耗水量和產量的影響方面，而對大田採用這種灌水式后的土壤入滲參數變化情況、作物需水量與耗水量計算、以及指導大田灌溉的水分下限控制指標等與大田生產實際密切相關的幾個問題基本上還沒有進行系統的深入研究，而這些問題如不能得到很好地解決，勢必會對這種灌水方式的推廣應用產生嚴重的影響。
