irrigation frequency

the primary study on response of growth, yield and dry matter of cucumber under different irrigation frequency in solar greenhouse

灌溉频率对日光温室黄瓜生长发育及干物质积累的响应

Results showed that solute application method and irrigation frequency has a great influence on solute transport.

结果表明,溶质施加方式和灌水频率对溶质迁移影响较大.

With increasing of irrigation frequency, pH decreased, organic content and total dissolved solid increased, ion concentration in soil solution changed obviously.

同时，随着灌溉次数的增加，土壤pH值降低，土壤有机质和全盐量增加；土壤溶液中各离子浓度有显著变化。

and appropriate to reduce the irrigation frequency and amount has little affects on yield, and can increase water use efficiency.

且适当减少小麦灌溉次数和灌水量对产量影响并不大，并能提高水分利用效率。

effect of irrigation frequency and amount on seed yield and yield components of russian wildrye

灌水对新麦草种子产量及产量构成的影响

effects of evaporation and irrigation frequency on soil water distribution

蒸发和灌水频率对土壤水分分布影响的研究

Nitrogen application could significantly increase grain yield under low irrigation frequency ( W0 and W1), while neglected effect on yield was observed with high irrigation frequency ( W2 and W3).

在低灌水频次（W0、W1）条件下，施氮具有明显的增产效应；而高灌水频次（W2、W3），施氮的增产效应不显著。
