Glutinous rehmannia anti-continuous-cropping yield-increasing agent and its preparing method

Abstract

The invention relates to a kind of glutinous rehmannia resisting repeated-planting production increasing agent, prepared from humic acid sodium, humic acid kalium, yellow humic acid cuprum and organic acid. It can effectively eliminate the restraint to repeated-planting glutinous rehmannia from the vegetal period secretion of the last planting glutinous rehmannia, decompound the deleterious substance in the soil damaging the growth of glutinous rehmannia, and accelerate the normal growth. The growing experiment result of the glutinous rehmannia repeated-planting growth proves that it can avoid rotating and converse planting, reduce plant disease, evidently improve output of glutinous rehmannia, and it has prominent effect in the effect application of glutinous rehmannia resisting repeated-planting growth.

Description

Technical field [0001] The invention relates to a fertilizer, in particular to a fertilizer for rehmannia rehmanniae resistant to repeated cropping and increasing production, and a preparation method of the fertilizer. Background technique [0002] Rehmannia glutinosa Libosch., also known as Shengdi, is the fresh or dry tuber of the perennial herb of the genus Rehmannia in the family Scrophulariaceae. Rehmannia glutinosa has unique medicinal value and health care function, and has always ranked first in the amount of Chinese medicinal materials. However, due to the hazards of Rehmannia glutinosa secretion, degenerative virus (DDV), Rehmannia X virus and CMV pathogens left in the soil after the growth of Rehmannia glutinosa, Rehmannia glutinosa cannot be planted repeatedly, and crop rotation must be strictly implemented. Generally, the rotation period in arid areas is 10-15 years, and the rotation period in flood and drought areas is 8 to 10 years. In the past, many methods...

AI Technical Summary

Problems solved by technology

In the past, many methods have been tried to obtain Rehmannia glutinosa virus-free plants through tissue culture, breeding resistant varieties of Rehmannia glutinosa, using pesticides to control viruses and bacteria, etc., but no breakthrough has been made in rehmannia glutinosa replanting

Our country has a lot of people and little land, and the rotation of crops has restricted the planting area of ​​rehmannia glutinosa, which has brought great difficulties to the professional and intensive production of rehmannia glutinosa
