[Method] The field experiment with three factors and two levels were applied for the study in order to research the effect of all treatments with the yield, quality, bearing branch, flower, fruit diameter of jujube. [Result]With different irrigation patterns, the result of comparing the length of bearing branch was drip irrigation furrow irrigation micro spray, and the result of comparing the number of bearing branch, the bud number, the flower number, fruit diameter was the same, as follows： drip irrigation microjet irrigation furrow irrigation; the result of comparing the yield was drip irrigation furrow irrigation microjet irrigation with significant differences. With different irrigation quantities, high irrigation water quantity treatment was proved higher than low irrigation quantity treatment in every survey index. [Conclusion] The analysis indicates that drip irrigation, microjet irrigation and furrow irrigation increased the irrigation water quantity can significantly promote the growth and the yield of jujube and the effects of the three kinds of irrigation patterns are drip irrigation furrow irrigation microjet irrigation.展开更多
[Objective]This study aimed to determine the number of microorganisms of cotton rhizosphere in a soil at various amounts of applied nitrogen fertilizer in a red date-cotton intercropping system.

[Method] In the field experiment, nitrogen fer-tilizer was applied at 0, 150, 300, 450, 600, and 750 kg/hm2, respectively. The dy-namic changes of the populations of bacteria, fungi and actinomycetes at the rhizo-sphere of cotton intercropped with red date were investigated. [Result] Microbial populations significantly increased at nitrogen fertilizer of 300 and 450 kg/hm2 during bud, flowering and bol opening periods. The numbers of bacteria and actinomycetes were higher during flowering and bol opening stages than at bud stage. The num-ber of fungi slightly changed during the entire growth period. Appropriate amount of nitrogen fertilizer （300 to 600 kg/hm2） was favorable to the survival of the microor-ganisms in the soil under the intercropping system. [Conclusion] The study provides a guideline for screening and determining the optimum amount of applied nitrogen fertilizer.展开更多
