Problems solved by technology

At present, there are mainly the following problems in Pinellia: (1) Since Pinellia was successfully transformed from wild to domestic species in the 1970s, after years of development, its cultivation has not made great progress. atrophy
(2) The sowing density of pinellia in different producing areas is very inconsistent, and farmers generally arrange the planting density of Pinellia according to their long-term planting habits
There is a serious lack of effective control methods for the diseases and insect pests of pinellia
(5) The processing method of pinellia has a great influence on the quality of pinellia, especially when sulfur is fumigated, it is easy to cause the sulfur dioxide of the medicinal material to exceed the standard, and the total alkaloid content decreases
[0004] There are many cultivation techniques of Pinellia recorded in the literature, but the cultivation methods are greatly affected by environmental factors in different regions, and it is difficult to unify the cultivation of Pinellia with systematic cultivation methods, and most of the research focuses on a certain aspect
[0005] The existing pinellia cultivation technology has the following disadvantages: large-scale and standardized cultivation cannot be achieved, and the cultivation method cannot meet the requirements of GAP; the yield is low, the quality is poor, and the quality is easy to degrade. The sowing time of pinellia is divided into winter sowing and spring sowing, which not only occupies land resources and also affect the quality of pinellia

Embodiment 2

[0035] 1. Site selection and site preparation

[0036] Pinellia is a perennial field weedy plant. It has no strict requirements on the soil and has a wide range of adaptability to the soil. It is wild in various types of soil, but it is neutral to slightly acidic in moist, loose, fertile, and soil pH ( pH value 5.5-6.8), sandy loam and light clay soil grow well. It is advisable to choose low mountains and hilly areas below 2000 meters above sea level, and choose loose, fertile, neutral or slightly acidic, red oil sandy soil, mountainous oil sandy soil, tidal sandy mud, purple sandy mud, and mountainous sandy mud with easy drainage and irrigation. Or lighter soils such as ash-packed soil. Choose slopes that can only be exposed to the sun in the morning. You can also choose half shade and half sun, humid and foggy gentle slope mountains. Avoid afternoon sun exposure. If it is cultivated in Pingba, it is best to interplant with high-stalk crops such as corn and sorghum, or to...

[0078] Choose loose, fertile, neutral or slightly acidic red oil sandy soil that is easy to drain and irrigate, turn the ground 20-25 cm in spring, and select tubers with a transverse diameter of 0.5 cm, robust, no pests and diseases, and regular shapes as seeds (plant stems). On February 20, the seeds were planted at 180 kg per mu, sprinkled with microbial organic fertilizers, and covered with soil. Pinellia topdressing 4 times during the growth period. For the first time, 1,000 kg of clear manure water was applied per mu after the seedlings were assembled in early April; for the second time, 2,000 kg of decomposed manure water was applied per mu during the bulbil formation period in the middle and late May; After the bulbils fall to the ground, topdress 50 kg of cake fertilizer or 500 kg of compost made of straw and manure together, and combine the soil to cover the fertilizer and bulbils; Add 50 kg of decomposed cake fertilizer, 20 kg of superphosphate, and 10 kg of urea, ...

Abstract

The invention discloses a high quality and yield culture technology of pinellia ternate, which comprises the following steps: land selection and preparation, seeds preparation, sowing, field management, harvesting and prevention and cure of plant diseases and insect pests. The technology of the invention is characterized in that: the loosening, fertile, neutral or subacid soil with convenient irrigation and relatively light texture, such as red oil sandy soil, hilly oil sandy soil, tide sandy mud, purple sandy mud, hilly sandy mud or ash pack soil, and the like, is chosen; before sowing, plough is carried out as per depth of 0.2m, and the suitable time for sowing is from February 20 to March 10, bottom fertilizer application is carried out according to the dosage of 180-220kg per mu, and soil is covered; before sowing, the medium-sized or small healthy stems which have the diameter of 0.5-1.5cm, regular shape and no plant diseases and insect pests are selected as the seeds (seed stems), and the stems are soaked into the 500-1000 times of liquid of 50% carbendazim for 10-20 minutes. The effect of the method is to improve the yield of pinellia ternate by 18%-22%, improve the water-soluble extracts by 10%-15%, increase the content of total alkaloid of by 18%-24%, and increase the benefit by 15%-20%.

Description

technical field [0001] The invention relates to a high-yield cultivation technology of Pinellia chinensis, including the processes of site selection, site preparation, seed selection, sowing, fertilization, fine field management, reasonable planting mode, scientific pest control measures and the like. Background technique [0002] Pinellia is the underground tuber of the Araceae plant Pinellia, which has a long history of medicinal use. It is produced in most parts of the country. Traditionally, it is better if it is white in color, firm in texture, and powdery enough. In the 2005 edition of the Pharmacopoeia, only Pinellia is processed. Method and TLC identification, there is no corresponding quality control index, the present invention uses water-soluble extract and alkaloid content as quality evaluation index (alkaloid is the material basis of the clinical curative effect of pinellia radiata recognized clinically now). At present, there are mainly the following problems i...
