Salvia miltiorrhiza has such a wide range of uses, what is its planting method? What is there to pay attention to?

Key points to be paid attention to in growing Salvia miltiorrhiza:

Salvia miltiorrhiza like warm and humid, cold-resistant and waterlogging, strong adaptability, except for the soil is too heavy or low-lying stagnant water, the general land can be planted. It is best to choose deep, fertile, loose, well-drained land for planting. When preparing the land, we should plough deeply, break up the soil and make beds.

Radix Salviae Miltiorrhizae is mainly propagated by the method of dividing roots. The stout new root can be selected as seed, and the root strip can be cut into 5 cm long root segments and planted between November and December. When planting, stand upright, do not invert up and down, and cover the soil 3 cm thick after planting. The root strip can also be placed horizontally in the sowing ditch, covering soil 5 cm, row spacing 25 cm, plant spacing 20 cm. It can also be propagated with seeds, which must be planted in the season of abundant rainfall in the year when the seeds are collected. After sowing, the grass should be covered and sun-dried frequently to keep moist. Seedlings can emerge after 7 days, and then transplant after the seedlings are strong.

Planting Salvia miltiorrhiza should apply more basic fertilizer as much as possible, and apply fertilizer several times during the growing period. Ploughing and weeding should be done in time, ditching and drainage should be paid attention to and moss should be divided into stages. In addition to leaving a seed to pull the plant, the inflorescence should be cut off several times during the flowering period to facilitate root growth.

The diseases and insect pests that need to be prevented in planting Salvia miltiorrhiza are as follows:

(1) Leaf spot disease: spray Bordeaux solution with 1purl and 150 Bordeaux solution during the onset period.

(2) Root rot: the method of prevention is to choose the land with high terrain and good drainage to plant. In the rainy season, the ditches should be dredged in time so that there is no stagnant water. During the onset of the disease, the root was perfused with 1000 times of carbendazim powder. Leaf spot disease: spray with Bordeaux solution of 1 / 1 / 1 / 1 / 150 / 1 / 1 / 1 / 1 / 1 / 1 / 1 / 150 during the onset of the disease.

(3) grub: generally harmful in autumn, the root can be poured with 1000-1500 times liquid of crystal trichlorfon, or it can be killed manually.

(4) Root-knot nematode disease: the main control methods are rotation, no continuous cropping, no continuous cropping with crops easily infected with the disease, leaving seeds and raising seedlings in disease-free land. Salvia miltiorrhiza can be harvested from late November to the end of December after a growing season. During harvest, the whole plant should be planed (be careful not to cut off the roots), shake off the soil, cut off the roots, abandon the Reed head, and then dry or dry. The fresh roots dug up should be dried as soon as possible to prevent freezing and decay.

(5) Land tiger: it can be caught in the early morning, or 100 grams per mu of crystal trichlorfon and 5 kilograms of fried rapeseed cake can be used as poison bait in the field.
