The latest seed price and planting method of Pinellia ternata

Pinellia ternata, also known as earth, field, taro and so on, is a medicinal plant of Pinellia ternata of Araceae, which is widely distributed in the Yangtze River Basin and Northeast and North China of China. It has the functions of drying and dampening phlegm, reducing adverse and stopping vomiting, eliminating ruffian and dispersing knots, and so on. Its cultivation value is high, so let's take a look at the seed price and planting method of Pinellia ternata.

How much is the seed of Pinellia ternata per jin?

The price of Pinellia ternata seeds is about 35-50 yuan per jin, but it varies according to the variety, quality, origin and quantity of seeds. Pinellia ternata is a large variety of commonly used medicinal materials. At present, due to wild resources being exploited and exploited indiscriminately, and artificial planting is rare, its prices rise year after year and demand exceeds supply, so the cultivation benefit is higher. After planting bulbs, it can be harvested in the same year. The yield of dry products per mu is about 150 kg, and the benefit per mu can reach more than 20,000 yuan.

Propagation methods of Pinellia ternata

1. Tuber propagation: after 2-3 years of cultivation of Pinellia ternata, underground tubers can be dug up every year after falling seedlings, small and medium-sized tubers with strong growth and free of diseases and insect pests can be selected as seeds, mixed with moderately dry and wet fine sand and stored in cool and ventilated places. take out and plant in the winter of the same year or in the spring of the following year.

2. Bulb propagation: in summer and autumn, mature bulbs under petiole are used for strip planting, with 3-5 buds per hole and 1.6 cm thick soil cover. At the same time, proper amount of mixed fertilizer is applied, which can not only promote the germination and growth of bulbs, but also increase the application of fertilizer for mother tubers.

3. Seed propagation: more than two-year-old Pinellia ternata can blossom and bear fruit one after another from early summer to autumn and winter. About 10 days after flowering in autumn, mature seeds are collected and stored in wet sand for seed use, but this method is used in seedling shortage or breeding.

Planting method of Pinellia ternata

1. Soil preparation and fertilization: the planting of Pinellia ternata is sunny, the soil layer is deep, the previous crop is leguminous and gramineous crops, the sandy soil rich in organic matter is planted, deep ploughing is used to make beds, 1500kg / mu of rotten farm fine fertilizer or soil miscellaneous fertilizer and 20kg / mu of calcium superphosphate are applied.

2. Sowing at the right time: the seeds can be sowed in Pinellia ternata, spring, summer and autumn, and it is better to sow seeds from late February to early March. The tubers are sown in ditches with a row spacing of 20 cm to 25 cm and a depth of 5 cm to 7 cm. The seed amount per mu is about 60 kg.

3. Seedling stage management: after sowing in Pinellia ternata, cover seeds with rotten farm manure or soil manure, then pour 1500kg to 2000kg clear manure water, cover soil and border surface flat. Generally, after 20 days, the mulch was observed every 2 days, and the mulch was removed after 6 pm when the emergence rate reached about 60%.

4. Intermediate ploughing and fertilization: about 20 days after Pinellia ternata was planted in the first ten days of April, 1000 kg of human and animal dung water was applied at 1:3 per mu. Check the field at any time, find weeds, should be pulled out in time, between the lines with a shallow hoe, a depth of about 2.5 cm, to avoid root damage.

5. Cultivate the soil at the right time: sown before the first ten days of March of Pinellia ternata, cultivate the soil once before June 10, use about 200 kilograms of fine mud at the bottom of the plough per mu, cover the border surface, about 1.5 cm thick, cover the bulbs and seeds and slightly suppress it, and cultivate the soil once on July 15 and September 10 respectively.

6. Irrigation and picking buds: Pinellia ternata likes to be moist and is afraid of drought. if it is sunny and dry for a long time, it should be irrigated for half an hour after 6 p.m. and if Rain Water is too much, it should be drained in time. Except for seed reproduction, all buds extracted during the growing period should be removed so that nutrients are concentrated on the growth of underground tubers.

Prevention and control of diseases and insect pests of Pinellia ternata

1. Leaf spot

[harm] Purple-brown spots appeared on the leaves at the initial stage of the disease, and there were many small black spots on the disease spots in the later stage. In severe cases, the leaves curled and scorched and died.

[prevention and treatment] before and at the initial stage of the disease, spray 1-D-1-D-120 Bordeaux solution or 60% Dysen zinc 500-fold solution, once every 7 days and 10 days, 2 times in a row.

2. Rot disease

[harm] it occurred in the season of high temperature and humidity and low-lying stagnant water. after the disease, the tubers rotted and the aboveground parts withered and yellow and the seedlings died.

[prevention and control] timely drainage in the rainy season, burrow with 5% lime milk at the initial stage of the disease, and timely control of underground pests can reduce the harm.

3. Virus disease

[harm] it occurs in summer, and the leaves of the plant are curled and twisted, forming a dwarf deformity.

[prevention and treatment] choose disease-free plants to leave seeds, immediately pull out the diseased plants and burn them centrally, and fill holes with 5% lime milk to prevent spread.

4. Red diamondback moth

[harm] it mainly bites the leaves, and when it is serious, it can eat up the leaves.

[prevention and control] manually killed or sprayed with 40% dimethoate milk 1500 × 2000 times or 90% trichlorfon 800 times 1000 times, once every 5 / 7 days, 2 / 3 times in a row.
