Cultivation method for improving continuous cropping yield and active ingredient content of salvia miltiorrhiza

Abstract

Provided is a cultivation method for improving continuous cropping yield and active ingredient content of salvia miltiorrhiza. According to the cultivation method, on the basis of original conventional production and plantation, some simple operation of applying potassium hydroxide and calcium magnesium phosphate fertilizer in the soil preparation process and additionally applying alkaline fertilizer and inorganic base in the growth topdressing process are added. In each acre, 1-2 kilograms of potassium hydroxide and 10-20 kilograms of calcium magnesium phosphate fertilizer are used; for the first topdressing in the growing period, 10-15 kilograms of ammonium bicarbonate is used in each acre; for the second topdressing in the growing period, 800-1200 grams of potassium hydroxide is used in each acre. By means of the cultivation method, implementation is simple, input is little, the salvia miltiorrhiza can be continuously cropped for one year, pest and disease damage aggravation caused by traditional continuous cropping of the salvia miltiorrhiza can be effectively prevented, and the problems of physiological seedling death and seedling withering, poor growth of the ground part and the underground part of the survived salvia miltiorrhiza, yield reduction and reduction of the active ingredient content are effectively solved. Because the salvia miltiorrhiza can be continuously cropped for one year through the method, the utilization rate of limited lands suitable for growing the salvia miltiorrhiza in a tunnel region is improved, the plant area of the salvia miltiorrhiza is multiplied, the total yield of the salvia miltiorrhiza is multiplied, and the quality of salvia miltiorrhiza medicinal materials is guaranteed.

Description

technical field [0001] The invention belongs to the field of cultivation of salvia miltiorrhiza, in particular to a cultivation method for improving the continuous cropping yield and content of active ingredients of salvia miltiorrhiza. Background technique [0002] Salvia miltiorrhiza is a medicinal plant of Labiatae. Its roots and rhizomes are generally used as medicine. It has the effects of promoting blood circulation and regulating menstruation, dispelling blood stasis and relieving pain, cooling blood and eliminating carbuncle, clearing heart and troubles, nourishing blood and calming the nerves. Accumulation of abdominal mass, tingling pain in the chest and abdomen, heat pain, swelling and pain in sores, restlessness, insomnia, hepatosplenomegaly, angina pectoris, it can be used alone or in combination with other traditional Chinese medicines. With the in-depth research on the application of Salvia miltiorrhiza, its uses are also increasing, and its demand is also inc...

AI Technical Summary

Problems solved by technology

However, crop rotation has greatly reduced the utilization rate of the already limited land area suitable for cultivation, greatly reduced the actual planting area of ​​Salvia miltiorrhiza, further reduced the total output of Salvia miltiorrhiza, and made the contradiction between supply and demand of Salvia miltiorrhiza more prominent.

The demand for Salvia miltiorrhiza is increasing, but the total output is decreasing year by year, and the quality of the medicinal materials of Salvia miltiorrhiza is also greatly declining. Therefore, it has become a major problem in production to solve the above problems with better methods.
