Method and system for predicting water demand for promoting seedling emergence of artificially planted agriophyllum quarrosum

Abstract

The invention discloses a method and system for predicting the water demand for promoting the seedling emergence of the artificially planted agriophyllum quarrosum. According to the air temperature inthe agriophyllum squarrosum planting period and the agriophyllum squarrosum planting earth surface dry sand layer depth, the lowest water supplementing amount of the agriophyllum squarrosum seedlingemergence can be accurately and rapidly predicted, and a rapid judgment basis for judging whether the rainfall in a sand area after natural rainfall meets the requirement of the seedling emergence ofthe artificially planted agriophyllum quarrosum is theoretically provided, so that the method and the system play an important guiding role in the artificial planting production of the agriophyllum squarrosum, meanwhile, have the positive significance in guiding and promoting the efficient utilization of the scarce water resources in the sand area.

Description

technical field [0001] The invention relates to the field of desert plants, in particular to a prediction method and system for artificial planting of sand rice to promote seedling emergence water demand. Background technique [0002] Salami is an annual herbaceous plant belonging to Chenopodiaceae. It is a pioneer plant in the succession of mobile sand dunes and sandy surface vegetation, and is also an important wild economic plant in sandy areas. Its seeds are rich in crude protein, threonine and other essential amino acids and Magnesium, potassium, zinc and other mineral elements are a traditional and natural functional green food. The domestic and foreign researches on sand rice mainly focus on the ecology of sand rice, the nutritional components of seeds, the characteristics of seeds and their moisture content. There are also scholars who use different hormones such as gibberellin, ethephon, fluridone, etc. to study on breaking the dormancy of Amyrrhoea seeds, and obta...

Problems solved by technology

[0003] However, about the amount of water required for the emergence of sand rice, that is, the soil moisture threshold for the emergence of sand rice seeds (abbreviated as "the water threshold for emergence of sand rice"), or the soil water replenishment amount for the emergence of sand rice seeds (abbreviated as "the water replenishment amount for emergence of sand rice"), and For different rainfall (or artificial watering) infiltration in different depths of dry sand layer (moisture content < 2%) on the surface of quicksand, different time for infiltration water to evaporate and dissipate to below 2% at different depths of sand layers, etc. Research on this aspect is still a blank
