Greenhouse pinellia ternate two-planting and two-harvesting cultivation method

Abstract

The invention provides a greenhouse pinellia ternate two-planting and two-harvesting cultivation method. The greenhouse pinellia ternate two-planting and two-harvesting cultivation method comprises the following steps that a single steel frame greenhouse is used, and the specification of the greenhouse is that the span is 6m, the top height is 2.5 m, the length is 20m, and the height of a ventilation opening is 1.5 m. Thin-wall steel pipes with the pipe wall thickness of 2.5 mm are made into arch rods, vertical rods and pull rods, and the distance between every two adjacent steel pipes is 1-1.2 m; a covering film is fixed by a film clamping groove; the cultivation of the pinellia ternate in a steel frame greenhouse is divided into spring advanced cropping and autumn delayed cropping; early spring crops are seeded in early February and the early spring crops are harvested in mid-to-late June; late autumn stubbles are seeded in late June, and late autumn stubbles are harvested from early and middle October to early November; and a medium is cultured in the greenhouse, and the medium is prepared from 20-30 parts of straw incineration materials, 20-40 parts of cow dung, 4-6 parts of rapeseed oil cakes, 5-8 parts of urea, 3-6 parts of potassium sulfate, 9-15 parts of calcium superphosphate, 3-7 parts of limestone powder, 2-6 parts of traditional Chinese medicine residues and 4-8 parts of EM complex microbial inoculants. The pH value is 7.0 to 7.6. Pinellia ternate produced through the method is large in size, full and easy to peel, the large grain rate (the diameter is 1.0 cm or above) reaches 55%, and the yield is increased by 1.0-1.5 times or above compared with that of common field cultivation.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a method for cultivating pinellia pinellia in greenhouses with two harvests per year. Background technique [0002] Pinellia, the dry tuber of the Pinellia araceae plant, is a commonly used traditional Chinese medicine. It was first recorded in "Shen Nong's Materia Medica" and listed as a low-grade product. It is a good medicine for cold drink with wet phlegm, vomiting, nausea, cough with excess phlegm, fullness of chest and diaphragm, phlegm reversal, headache, dizziness and insomnia and other symptoms. [0003] There are more than 500 kinds of new drugs, special medicines and Chinese patent medicines in my country with pinellia as the main raw material, and more than 500 Chinese herbal medicine processing enterprises use pinellia as the main raw material to process ginger Pinellia, Qing Pinellia, Bamboo Lek Pinellia, and Pinellia Xiaqu and other traditional Chinese medicin...

Problems solved by technology

[0004] However, in the cultivation of pinellia, there are problems such as degeneration of species, aggravation of diseases and insect pests, quality decline, reduction of medicinal material production, and reduction of income of farmers, which seriously affect the yield and quality of the back-end medicinal materials of pinellia.
