Problems solved by technology

In recent years, due to uncontrolled excavation, the resources of wild Glycyrrhiza inflata in Xinjiang have been severely damaged, and the population has dropped sharply, making it difficult to meet market demand. Therefore, the artificial cultivation and wild tending of Glycyrrhiza inflata is imminent

Embodiment 1

[0023] Embodiment 1: the plantation site of Glycyrrhiza inflata in the test site. Three replicates were set up, each sample area was 4m×4m, and the distance between each plot was 0.5m. According to the setting and layout of the sample plot, deeply plow the saline-alkali land for 40-60cm, sprinkle sand on the soil surface for 3-5cm, and all treatment requires 12.96m of sand 3 -21.6m 3 . The surface of the planting site is shallow ditch <5mm, sow the treated Glycyrrhiza inflata seeds with a plant spacing of 40cm, cover the seeds with a thin layer of soil, and then cover them with film. After sowing, carry out field management, water and fertilize regularly, the fertilizer is mainly manure with high phosphorus content, licorice has 5-6 true leaves on the seedlings and timely loosen the soil after it rains, another aspect of field management is To prevent edge effects, a ridge with a height of 10 cm and a width of 20 cm at the bottom was set 1 meter away from the edge of the en...

Abstract

The invention discloses a glycyrrhiza inflata planting and soil improvement desalting method for saline-alkali soil. The method is characterized by comprising the following steps of selecting a proper planting area according to the conditions that the NaCl and Na2SO4 resistance of glycyrrhiza inflata is higher than that of NaHCO3, the salt composition of planting soil is mainly chloride-sulfate, and the total salt amount range is 0-1.3% (0-211.06 mmol / L); performing deep ploughing, sand laying and other measures on the discarded saline-alkali soil before planting; pretreating glycyrrhiza inflate seeds with industrial sulfuric acid; sowing at the plant spacing of 40 cm; and regularly watering and fertilizing, intertilling and loosening soil, and arranging ridges to prevent edge effect. According to the method, soil salinity rising can be inhibited, the soil structure can be improved, the soil fertility can be increased, the soil environment of the abandoned saline-alkali soil is further improved, meanwhile, the defects of wild glycyrrhiza inflate resources are effectively overcome, and the win-win situation of sustainable utilization of medicinal plant resources and saline-alkali soil improvement is achieved.

Description

technical field [0001] The invention relates to the field of saline-alkali land improvement methods, in particular to a saline-alkali land improvement method for licorice inflating. Background technique [0002] China is a country with a large amount of saline-alkali land, ranking third among the top 10 countries with saline-alkali land area. China's saline-alkali land is distributed in 17 provinces including the Northwest, Northeast, North China and coastal regions. The total area of ​​saline-alkali wasteland and saline-alkali land affecting cultivated land exceeds 500 million mu, of which the agricultural development potential accounts for more than 10% of China's total cultivated land. Rational development and utilization of these saline-alkali land resources is of great significance to ensuring food security in my country, promoting sustainable agricultural development, improving the ecological environment, and promoting coordinated regional economic and social developmen...
