Red-rooted salvia root cultivation method capable of achieving continuous cropping

Abstract

The invention provides a red-rooted salvia root cultivation method capable of achieving continuous cropping. On the basis of original conventional production and planting, only several simple operations including applying potassium hydroxide and plant ash during soil preparation and applying basic fertilizers during top dressing in a growing period are added to the red-rooted salvia root cultivation method capable of achieving continuous cropping. The red-rooted salvia root cultivation method capable of achieving continuous cropping includes: applying 1-2 kilograms of the potassium hydroxide and 20-40 kilograms of the plant ash per mu; applying 10-15 kilograms of ammonium hydrogen carbonate per mu during primary top dressing in the growing period; and applying 15-25 kilograms of calcium magnesium phosphate per mu during secondary top dressing in the growing period. The red-rooted salvia root cultivation method capable of achieving continuous cropping is simple to implement, small in input and large in harvest, enables red-rooted salvia roots to be capable of being continuously cropped for one year and is capable of effectively preventing the problems of aggravated pest and disease damage, physiological dead seedlings and withered seedlings, underground part growth amount decrease, decrease of the number, diameters and lengths of root systems, lower output, active ingredient content reduction and the like of conventional red-rooted salvia root continuous cropping. Since one-year continuous cropping can be achieved, use ratio of limited land suitable for planting the red-rooted salvia roots is increased in geo-authentic production regions, the plantable area of the red-rooted salvia roots can be multiply increased, and further, total output of the red-rooted salvia roots can be multiply increased, and the quality of red-rooted salvia root medicinal materials is guaranteed.

Description

technical field [0001] The invention belongs to the field of cultivation of salvia miltiorrhiza, and in particular relates to a cultivation method of salvia miltiorrhiza capable of continuous cropping. Background technique [0002] Salvia miltiorrhiza is a medicinal plant of Labiatae. Its roots and rhizomes are used as medicine. It is bitter in nature and slightly cold. Indications for irregular menstruation, amenorrhea, dysmenorrhea, accumulation of lumps in the abdomen, tingling pain in the chest and abdomen, heat arthralgia pain, sore swelling and pain, restlessness and insomnia, hepatosplenomegaly, angina pectoris, and it is mainly used in combination with other traditional Chinese medicines. In recent years, the research on the application of Salvia miltiorrhiza has become more and more in-depth, its uses are also increasing, and its demand is also increasing. The demand stimulates production and excavation. The large-scale excavation in successive years has seriously d...

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.
