Planting time and High-yield cultivation techniques of Pinellia ternata

As the saying goes, everything is difficult at the beginning, a good beginning is equal to half of success, and this is roughly the case for everything. The most important thing to plant Pinellia ternata is to choose a good planting time for Pinellia ternata. Only in this way can we lay a good foundation for the future planting process of Pinellia ternata.

Planting time of Pinellia ternata

The season of planting Pinellia ternata should be determined according to the local climate. In the south of the Yangtze River, Pinellia ternata should be planted in Yangchun in February. In the north and north, the planting time of Pinellia ternata should be postponed, and it is best to plant it from April to May.

High-yield cultivation techniques 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.

Living environment of Pinellia ternata

1. Temperature: when the average ground temperature is about 10 ℃, Pinellia ternata germinates and seedlings emerge, and when the average temperature reaches 15 ℃ ~ 27 ℃, Pinellia ternata grows the most. In some parts of China, since mid-July, with the end of the plum rain season, the temperature rises, and the highest temperature often exceeds 35 ℃. The growth of Pinellia ternata is seriously affected, and the aboveground parts of Pinellia ternata without shade die one after another, forming summer seedlings. The suitable temperature for Pinellia ternata growth is 23 ℃ ~ 29 ℃.

2. Humidity: Pinellia ternata is not tolerant to drought and likes to grow in the soil with high humidity. We have investigated a high yield field of Pinellia ternata in Zhongxing Town, Shan County, with an average tuber yield of 1500 kg. Its variety is "narrow clover Pinellia ternata" in Heze, there is almost no obvious seedling falling process in the whole year, and the growth is very exuberant even in the midsummer season. One of the main measures is to irrigation with well water ditch once every evening in summer, which not only keeps the soil moist, but also lowers the soil temperature, killing two birds with one stone. Pinellia ternata both like and afraid of water, when the soil moisture exceeds a certain limit, but poor growth, resulting in rotten root, rotten stem, seedling death, tuber yield decreased.

3. Light: Pinellia ternata is a shade-tolerant plant rather than a shade-loving plant, which can grow luxuriantly under moderate shading conditions. However, if the light is too strong, Pinellia ternata is difficult to survive. The number of bulbs and the weight gain of tubers can reach the maximum in semi-shade environment.

Harvest and processing of Pinellia ternata

1. Harvest: the seeds sown were harvested in the 3rd and 4th year, and the tubers propagated in the same year or the second year. The stems and leaves withered and fallen seedlings were dug in summer and autumn, and it was better to harvest between Grain in Beard and the Summer Solstice in summer. Choose sunny days to dig carefully when digging to avoid damage. Shake off the mud and sand, put it in the basket and cover it, do not expose yourself to the sun.

2. Processing: wash the sediment of fresh Pinellia ternata, divide it into sacks according to large, medium and small grades, first gently beat it on the ground, then pour it into a clear water tank and knead it repeatedly until the outer skin is clean. Then take out the sun, and constantly turn, in the evening flat spread indoors to dry, and then take out to dry the next day, that is, Pinellia ternata.

As the producing area of Pinellia ternata is widely distributed, we need to make a detailed division of the planting time of Pinellia ternata according to the region when planting Pinellia ternata, so as to improve the survival rate of Pinellia ternata and realize the yield and planting benefit of Pinellia ternata. Increase planting income.
