A method of planting Scutellaria baicalensis covered with black plastic film

Abstract

The invention discloses a method for planting scutellaria baicalensis through whole black mulching film coverage. The method comprises the steps of (1) land selection and land preparation, (2) planting, (3) intertillage and weed control, (4) topdressing, (5) pest control, (6) bud picking and (7) seed collection. The method is characterized in that before seedlings are planted, the roots of the seedlings are soaked in liquid pesticide; when the seedlings are planted, ditching is conducted, a ditch is paved with a layer of ash by 0.5 cm to 1.0 cm in thickness, the seedlings are placed on the walls of the ditch by inclining by 45 degrees according to row spacing, ash is scattered by 0.8 cm to 1.5 cm in thickness, and finally, the ground is covered with soil by 2 cm to 3 cm in thickness; after the seedlings are planted by six rows, the ground is coved with a black mulching film with the width of 120 cm, the film is drawn to be expanded, the edges of the film are covered with soil by 7 cm to 10 cm in thickness, and holes where the seedlings are planted are scraped by a knife so that the seedlings can be exposed when the seedlings sprout to break the ground 18 to 20 days after planting. According to the method, the ground is covered with the whole black mulching film, so that the purposes of soil moisture conservation and fertilizer conversation are achieved, surface temperature rising is facilitated, the transplanting time is made to be earlier, growth of weeds is restrained, and the yield and quality are improved.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese herbal medicines, and in particular relates to a method for planting scutellaria baicalensis covered with black plastic film. Background technique [0002] Scutellaria baicalensis is a perennial herb of the Labiatae family, also known as camellia root and Tujincha root. The root is used as medicine. It has the effects of clearing away heat and dampness, cooling blood and preventing miscarriage, and detoxifying. It is mainly used for febrile diseases, upper respiratory tract infections, lung-heat cough, Damp-heat jaundice, pneumonia, dysentery, hemoptysis, red eyes, restless fetus, high blood pressure, carbuncle and boils. Clinical application shows that the antibacterial effect of Scutellaria baicalensis is better than that of Coptis chinensis, and it does not produce drug resistance, so it is a high-quality Chinese medicinal material. [0003] Scutellaria baicalensis grows wild on sunny...

Problems solved by technology

[0004] However, the current planting of Scutellaria baicalensis still adopts the traditional direct-seeding planting, which is highly dependent on the weather, soil moisture and surface temperature cannot be effectively controlled, which affects the germination rate of seeds, and the traditional planting method also has the problem of many weeds

Aiming at the problems existing in the traditional planting method, the patent CN101353638A discloses a method for cultivating Scutellaria baicalensis tissue, which uses the technical means of cutting and inoculating to cultivate Scutellaria baicalensis seedlings, which can speed up the seedling cultivation, but the cost and investment are large, which cannot be accepted by the majority of medicinal material growers; Patent CN102084771A discloses a method for cultivating Scutellaria baicalensis medicinal materials, which uses interplanting of forest medicines and cutting seedlings to improve land utilization and increase the rate of live seedlings. However, the cutting process requires large labor costs, which affects the economic benefits of Scutellaria baicalensis planting; Patent CN102349412A discloses the cultivation method of Scutellaria baicalensis, which adopts the means of soil treatment and seed treatment. On the one hand, the purpose of preventing waterlogging and loosening the soil is achieved by making a bed, and on the other hand, the soil is mixed with Miller granules to prevent pests. Inconvenient temperature control, large dosage of drugs and easy failure, fast growth of weeds, frequent weeding, resulting in increased costs

The method of planting crops with plastic film covering has become one of the most common methods. However, the traditional method of planting Scutellaria baicalensis with plastic film mulching will increase the number of diseases due to the high surface temperature. It makes weeds grow faster, which not only reduces the water absorption and fertilizer absorption ratio of Scutellaria baicalensis, but also increases the humidity and heat of the soil, and also increases the occurrence of diseases
