Abstract

The invention relates to a planting technology of pinellia ternata, which belongs to the field of medicinal plant planting, wherein pinellia ternata plants are short and small, soil is loosened and weed is removed frequently during growth, grassy waste is avoided, and because roots of pinellia ternata grow around tubers and are intensively distributed on a surface soil layer with the depth of about 10-15cm, early removal and small removal are achieved during weeding. In the harvesting process, the traditional harvesting method is adopted, the harvesting efficiency is low, pinellia ternata and underground stems are extremely short, 1-2 tuberous roots and a large number of fibrous roots can be generated on the stems, the root tips of the larger tuberous roots are often rotten, and the tuberous roots can be propagated. The planting technology of the pinellia ternata overcomes the defects, and the yield and the quality of the pinellia ternata are effectively increased by adopting the methods of seed selection, soil preparation, planting, management, harvesting and storage, so that the economic efficiency of a grower is improved.

Description

Planting technology of pinellia ternata

Technical Field

The invention relates to a planting technology of pinellia ternata, and belongs to the field of medicinal plant planting.

Background

Pinellia ternata (Thunb.) Breit is a plant of Araceae. The dried tuber is used as a medicine, and has the effects of eliminating dampness and phlegm, lowering adverse qi, preventing vomiting and dissipating stagnation. At present, the production of pinellia ternata is derived from wild and artificially planted pinellia ternata. With the development of the traditional Chinese medicine industry, the dosage of pinellia ternate is larger and larger, and wild resources obviously cannot meet the requirements. Because pinellia ternata is short and small, soil and weed are frequently loosened during the growth period, and grassy waste is avoided, because the roots of pinellia ternata grow around tubers, and the root systems of pinellia ternata are intensively distributed on a surface soil layer with the depth of about 10-15cm, the early and small weeding is realized. In the harvesting process, the traditional harvesting method is adopted, the harvesting efficiency is low, pinellia ternata and underground stems are extremely short, 1-2 tuberous roots and a large number of fibrous roots can be generated on the stems, the root tips of the larger tuberous roots are often rotten, and the tuberous roots can be propagated.

Disclosure of Invention

The planting technology of the pinellia ternata overcomes the defects, adopts the methods of seed selection, soil preparation, planting, management, harvesting and storage, effectively increases the yield and quality of the pinellia ternata, and improves the economic efficiency for farmers.

The pinellia ternata planting method is characterized by comprising the following steps:

1) selecting pinellia tuber with diameter of 0.5-1 cm as seed, soaking in 800 times of 50% sterile solution for 10-20min, taking out, and draining;

2) selecting land and preparing land, selecting a flat land block without water accumulation, deep ploughing by using a large tractor, repeatedly smashing, ridging by 10-15cm in height, 6-8 cm in depth and 15-18 cm in ridge width;

3) planting in selective days, namely sowing the seed stems or the seed stems subjected to germination acceleration on ridges at a planting distance of 5-8cm in the last ten days of March, wherein the depth is 3-5cm, covering a layer of heat preservation film on the ridges after sowing, and pressing the two sides by soil blocks;

4) the method comprises the following steps of (1) carrying out field management, keeping soil moist after planting, poking a small hole at a sprouting place after 5-10 days, watering after 20 days, topdressing after 30 days, mixing according to 10 kg/mu of calcium superphosphate, 200 kg/mu of organic fertilizer and 5-8 kg/mu of nitrogen fertilizer, shading by using a 50-80cm high shed in the middle ten days of the 5 th month of the lunar calendar, weeding 3-4 times when harvesting, taking care when weeding each time, and not turning over soil blocks too much;

5) harvesting when selecting, removing the shed frame on the ground surface in advance when the water content of the soil is lower than 10% in late 8 th month of the lunar calendar, cutting off dead leaves and weeds above the ground surface, dragging the pear with the inclined hook by using a large tractor to deeply turn over for 25-35cm, and then repeatedly raking up the mature pinellia ternata along the ground surface by using a multi-tooth rake;

6) and packaging and storing, namely turning the pinellia tuber to and fro by using the tuber, shaking off attached soil, cutting off fibrous roots by using scissors when the water content is 45-55%, using a cloth bag to pack the fibrous roots and placing the fibrous roots at a dark and moist position for temporary storage, and using a gunny bag to intensively store the tuber of the pinellia tuber.

Has the advantages that: because pinellia ternata is short and small, soil and weed are frequently loosened during the growth period, and grassy waste is avoided, because the roots of pinellia ternata grow around tubers, and the root systems of pinellia ternata are intensively distributed on a surface soil layer with the depth of about 10-15cm, the early and small weeding is realized. In the harvesting process, the traditional harvesting method is adopted, the harvesting efficiency is low, pinellia ternata and underground stems are extremely short, 1-2 tuberous roots and a large number of fibrous roots can be generated on the stems, the root tips of the larger tuberous roots are often rotten, and the tuberous roots can be propagated. The planting technology of the pinellia ternata adopts the methods of seed selection, soil preparation, planting, management, harvesting and storage, so that the yield and the quality of the pinellia ternata are effectively increased, and the economic efficiency is improved for farmers.
