Problems solved by technology

At present, the main way to prevent and control the harm of root-knot nematode is to use chemical agents. However, a large amount of pesticide spraying not only pollutes the environment, but more importantly, causes the content of heavy metal pesticide residues in Danshen medicinal materials to exceed the standard, which seriously threatens the safety of clinical medication.

Embodiment 1

[0040] Salvia planting, the steps include:

[0041] (1) Choose soil and optimize the environment

[0042] In late October, choose loose and fertile, well-drained, sandy soil with a pH of 6.5 to 7.5 and a mature soil layer thickness of more than 25 cm;

[0043] (2) Balanced fertilization, enough for one time

[0044] Apply 2500kg of farmyard manure per mu, and at the same time apply 50kg of superphosphate per mu as base fertilizer;

[0045] (3) Ridging

[0046] After balanced fertilization, ridging and leveling shall be carried out according to the standards of ridge width 60cm, ridge height 15cm, and ridge spacing 90cm;

[0047] (4) Mulching

[0048] Cover the ridge with 0.006mm thick plastic film, and press the sides of the plastic film with soil;

[0049] (5) Seedling transplanting

[0050] In late March of the following year, select two-year-old Danshen root segments that are consistent in growth, robust, free of diseases and insect pests, and have a diameter of 0.5-1...

Embodiment 2

[0054] On the plot of embodiment 1 harvesting salvia miltiorrhiza, sweet potato is planted, and step comprises:

[0055] (1) Land preparation and ridging

[0056]The land after Salvia miltiorrhiza is harvested is plowed and harrowed until the soil is soft and smooth. After raking, the mixed fertilizer composed of farmyard manure and erythromycin dregs is applied at 300 kg / mu (the mass ratio of farmyard manure and erythromycin dregs is 55:1), when the relative soil moisture content is 75% and above, the ridge width is 25-40cm, the ridge height is 20-30cm, and the ridge spacing is 10cm;

[0057] (2) Sowing potato seedlings

[0058] Select sweet potato seedlings (Jixu 23) with a length of 10-15 cm, keep 2-3 sweet potato leaves on the top, dip the roots in root powder and plant them on the ridge, and the distance between the plants of sweet potato seedlings is 10-12 cm;

[0059] (3) Field management and harvesting

[0060] 20-30 days after planting the sweet potato seedlings, d...

Embodiment 3

[0064] On the plot where sweet potatoes were harvested in Example 2, Salvia miltiorrhiza was planted in the same way as in Example 1 (that is, the second round of planting Salvia miltiorrhiza in the same plot).

Abstract

The invention relates to a method for reducing an obstacle in continuous cropping of radix salviae miltiorrhizae. The radix salviae miltiorrhizae and sweet potatoes are continuously cropped in a same field, wherein the radix salviae miltiorrhizae is planted by using a horse ear-shaped root segment propagation method, with a high survival rate, the sweet potatoes are planted after the radix salviae miltiorrhizae is harvested, after the sweet potatoes are harvested, and the radix salviae miltiorrhizae is further continuously cropped; plantation of the two kinds of crops are alternatively performed per year. When the sweet potatoes are planting, soil environment is improved and root knot nematodes of the radix salviae miltiorrhizae accumulated at roots of the sweet potato are inhibited and killed by a regulator, the radix salviae miltiorrhizae is planted after the sweet potatoes are harvested, and the quantity of the nematodes of the radix salviae miltiorrhizae is significantly reduced. The radix salviae miltiorrhizae cultivation mode provided by the invention is convenient in continuous cropping method, easy to implement, high in root segment survival rate, significantly increased in yield per unit area, and can continuously plant the radix salviae miltiorrhizae in the same field without applying fertilizer and herbicide, and artificial weeding is basically not needed, and thus cost is saved, improvement of the soil environment is facilitated, use amount of chemical fertilizer and pesticide are greatly reduced, and the method is safer and more environment-friendly.

Description

technical field [0001] The invention relates to a method for reducing obstacles to continuous cropping of salvia miltiorrhiza, in particular to a method for reducing obstacles to continuous cropping by utilizing salvia miltiorrhiza and sweet potato in rotation. Background technique [0002] With the surge of the trend of "returning to nature", traditional natural herbal medicines are becoming more and more popular. Salvia miltiorrhiza Salvia miltiorrhiza The dried roots and rhizomes of the herb have the effects of promoting blood circulation, removing blood stasis, dredging menstruation and relieving pain. It is a commonly used bulk medicinal material in clinical practice. It is known as "the largest pharmaceutical industry raw material" and is also a popular medicinal material developed internationally. Secondary metabolites in medicinal plants are usually an important material basis for the clinical efficacy of Chinese herbal medicines. The 2015 edition of "Chinese Pharma...
