Salviae miltiorrhizae cultivation method capable of lowering continuous cropping bad effect

Abstract

Provided is a salviae miltiorrhizae cultivation method capable of lowering continuous cropping bad effect. A plurality of simple operations of lime applying and plant ash applying during soil preparation and alkaline fertilizer adding during topdressing in a growing period are added on the basis of original conventional production plantation. 20-40kg of lime and 30-50kg of plant ash are applied each mu. During first topdressing in the growing period, 10-15kg ammonium bicarbonate is applied each mu, and during second topdressing in the growing period, 15-25kg calcium magnesium phosphate is applied each mu. Applying is easy, investment is low, harvest is high, salviae miltiorrhizae can be continuously cropped for a year, the problems that during salviae miltiorrhizae traditional continuous cropping, plant diseases and insect pests are aggravated, physiologic seedling dying and withering happen, growth amount on and under ground is decreased, root system number, diameter and length are reduced, harvest is lowered, and active ingredient content is lowered are effectively prevented. Due to the fact that continuous cropping can be carried out for a year, using rate of limited soil which is suitable for planting the salviae miltiorrhizae in authentic producing areas is improved, the plantable area of the salviae miltiorrhizae is increased manifold, and accordingly total output of the salviae miltiorrhizae is increased manifold.

Description

technical field [0001] The invention belongs to the field of salvia miltiorrhiza cultivation, and in particular relates to a salvia miltiorrhiza cultivation method for reducing adverse effects of continuous cropping. Background technique [0002] Salvia miltiorrhiza is a medicinal plant of Labiatae. Its dried roots and rhizomes are often used. 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, upset and insomnia, hepatosplenomegaly, angina pectoris, 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. Demand stimulates production and excavation. Years of large-scale excavation have seriously damaged wild resour...

Problems solved by technology

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