Technical Field

The invention relates to the technical field of asparagus planting, in particular to a method for improving soil for asparagus planting.

Background

Asparagus is one of ten major vegetables in the world, also called asparagus. The asparagus is entitled as the king of vegetables in the international market, is rich in various amino acids, proteins and vitamins, has higher content than that of asparagine and trace elements such as selenium, molybdenum, chromium, manganese and the like in common fruits and vegetables, particularly asparagus, has the effects of regulating body metabolism and improving body immunity, and has strong inhibiting effect and pharmacological effect in the prevention and treatment of hypertension, heart disease, leukemia, edema, cystitis and the like.

Asparagus is originally produced in east coast and Xiaoyai of the Mediterranean sea, and still has wild species in Europe, Asian mainland, North African grassland and valley zone, the cultivation history is more than 2000 years, the Asparagus is transferred to America in 17 th century, Japan is transferred in 18 th century, and China is transferred in 20 th century. From the 80 s in the 20 th century, the industrial development of asparagus in China began, but the planting technology has not been greatly broken through all the time because of the late start, and particularly, effective research is not carried out on the aspect of scientific utilization of soil, so that the soil hardening is serious, and generally comprises the following reasons: after the nitrogen fertilizer is excessively applied to the soil, the nitrogen supply of microorganisms is increased, correspondingly consumed carbon is increased, the consumed carbon comes from soil organic matters, the content of the organic matters is low, and the activity of the microorganisms is adversely affected, so that the formation of soil aggregate structures is affected, and soil hardening is caused; when the phosphate fertilizer is excessively applied to the soil, phosphate ions in the phosphate fertilizer are combined with cations such as calcium, magnesium and the like in the soil to form insoluble phosphate, so that the phosphate fertilizer is wasted, and the granular structure of the soil is destroyed, so that the soil is hardened; when the potassium fertilizer is excessively applied to the soil, the potassium ion replacement property in the potassium fertilizer is particularly strong, and polyvalent cations forming a soil aggregate structure can be replaced out, so that the soil is hardened.

Therefore, a method for improving the soil for planting asparagus is an urgent problem to be solved.
