Rice, one of the three major crops in the ningxia irrigation area of yellow river. is widely planted. the traditional irrigation techniques of rice are flood irrigation and deep storage. which need more water consumption and have higher application volumes. with the increase in population, the development of industrial and agricultural production and the uniform catchment agreement for the water resource of yellow river, the supplying and demand contradiction of the water resources in ningxia is more evident, then drang is presented for developing water - saving and efficient agriculture
近年來，水稻節水控灌技術在寧夏引黃灌區推廣后取得了顯著的經濟和社會效益。但如何確定節水控灌技術是現有條件下適合寧夏引黃灌區特別是鹽堿耕地的水稻種植先進灌溉技術，如何確定鹽堿地的淋洗水量及灌水模式，探索節水控灌技術在鹽堿地的適應性，研究水稻節水控灌技術增產機理，對進一步推廣水稻節水控灌技術及改良、開發鹽堿地和鹽堿荒地具有重要意義。 -
Using plots with water and fertilizer fully controlled, the effect of photosynthetic characteristic and yield under different treatments of water and fertilizer coupling was investigated. the result showed that photosynthetic rates are different among treatments of water and fertilizer coupling, and the change of stomatal conductivity is the same as photosynthetic rat. there is almost no influence on evaporation rate and cellular co2 concentration the combination of fertilizer and manure under natural rainfall is beneficial to the maintenance of photosynthetic rate during grain filling, thus results in highter yield and good quality. however, the coupling of fertilizer and manure with sufficient water results in the decline of photosynthetic rate and stomatal conductivity, the yield decreased indicating there has a balance ratio between water and nutrients ( fertilizer and manure ) supply. the study proposed that the optimum management to exploring yield and qlality potential is the combination of fertilizer and manure application with no irrigation
利用可精確控制水分條件的水肥平衡場，在不同水肥耦合處理的條件下，研究了水肥耦合對玉米光合特性及產量的影響，結果表明:不同水肥耦合處理的條件下，玉米的光合速率有所不同，氣孔導度的變化與光合速率的變化表現基本一致，而對蒸騰速率、細胞間co2濃度影響不大.其中，在自然降水條件下，有機肥和無機肥的配合，有利於玉米子粒灌漿期維持較高的光合速率，表現出良好的產量潛力.充足水條件下，有機肥和無機肥的配合，光合速率及氣孔導度表現較低，表現產量有所下降，說明供水量與施肥量之間有一個平衡系數.表明黑龍江省北部黑土區自然生態條件下，為充分發揮玉米的產量潛力，最佳的管理措施是增施無機肥和有機肥的配合 -
The first part is about the computing of crop water requirements ( or crop evapotranspiration ) and net irrigation requirements ( nir ) of ten crops in bojili irrigated district. then the traditional irrigation schedules of winter wheat and summer maize, which are the main crops in bojili, were evaluated with simulating model isareg. third, the field application efficiency in the experimental areas was evaluated from three methods
本文即是由灌區實測資料計算各種作物需水量，推求其凈灌溉需水量；然後通過模型檢驗現行作物灌溉制度是否具有合理性，並對田間灌溉系統進行評價，求其實際田間灌溉效率；最後由兩種不同灌溉制度方案的對比，確定試區合理的作物灌溉制度，在此基礎上求出各代表年的田間灌溉需水量和用水過程線。 -
According to the manner of possible water shortage in future, the water deficit treatment was designed with controlled water application method ( reduce water application with irrigation date remaining unchanged according to the irrigation schedule in use ) which is more suitable to the irrigation management of the local area
結果表明，兩種作物相對減產量與相對虧水量的線性相關系數偏低，顯示除缺水程度外缺水時間對產量也有顯著影響，線性模型僅比較粗略地表達這兩種作物的產量與全生育期水分的關系。 -
Nitrate content of rape and coriander increased with higher nitrogenous fertilizer application and lower water supply. nitrogen leaching in the soil increased with higher nitrogenous fertilizer application and water supply in column and micro - plot experiments, especially on higher irrigation and higher nitrogenous fertilizer. there was little nitrogen leaching when n application was below 135 kg / hm2, but n use at a rate of 270 kg / hm2 increased nitrogen leaching in the soil
在一定的施氮量下，硝態氮的積累峰值隨著灌水量的增加而下移， 150mm灌水量下田區試驗和模擬土柱試驗0 100cm土體內硝態氮的積累峰值分別出現在0 30cm和50 70cm ； 250mm灌水量下分別出現在40 60cm和60 80cm ； 350mm灌水量下田區試驗中0 100cm土體硝態氮沒有出現峰值，而模擬土柱試驗在80 100cm則有明顯的積累。
