Identification method and identification system of suitability for crop aerated irrigation

Abstract

The invention discloses an identification method of suitability for crop aerated irrigation. The identification method comprises the following steps: arranging at least three control samples, cultivating a first control sample in low-bulk density soil, cultivating a second control sample and a third control sample in high-bulk density soil and introducing air into the third control sample; introducing the air into the third control sample, thereby being capable of contrasting with the second control sample, and cultivating crops in the same other external environments by the three control samples; weighing after culturing the set time to obtain the yield decreasing range of the second control sample relative to the first control sample, and the yield increasing range of the third control sample relative to the second control sample; obtaining sensitivity indexes according to the yield decreasing range and the yield increasing range. The method compares the second control sample with the first control sample and the third control sample respectively, and combines two comparison results, so that a more accurate and reliable judgment result can be obtained. The invention further provides an identification system of the suitability for the crop aerated irrigation, therefore, a same technical effect can be reached.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, and further relates to a method for identifying the suitability of crop aerated irrigation. In addition, the invention also relates to a crop aerated irrigation suitability identification system. Background technique [0002] Aerated irrigation or aerated irrigation is currently a research hotspot in water-saving irrigation technology. It is a new technology for increasing production with integrated application of water and fertilizer, underground drip irrigation, steam reduction and water-saving technology. Optimize the soil gas environment to achieve further water saving, yield increase and quality improvement. [0003] However, it is still in the exploratory stage at present, and experiments are mainly carried out on a few kinds of crops. Different crops have very different responses to the effect of aerated irrigation, and the influencing factors are relatively complicated. A crop o...

[0003] However, it is still in the exploratory stage at present, and experiments are mainly carried out on a few kinds of crops. Different crops have very different responses to the effect of aerated irrigation, and the influencing factors are relatively complicated. A crop often needs to go through a large number of multi-point experiments to clarify its specificity. The effect of aerated irrigation
