Tips for planting Pinellia ternata

Pinellia ternata is generally sown from February to April in spring, and the hotbed can be used to accelerate the germination of the seed stem, and the temperature of accelerating germination can be kept at about 20 ℃. When the coleoptile is white, it is necessary to soak the soil thoroughly before planting, and then the seed stem with bud head is planted in the ploughed land. Base fertilizer and topdressing can be selected to apply farm manure, and interplanting can be carried out between the rows of young fruit trees. after bolting and flowering, buds should be removed in batches, and sodium sulfite solution can be sprayed in the later stage to delay the seedling falling of the plant.

First, sprouting before sowing and plastic film mulching at seedling stage

1. Generally sowing Pinellia ternata from February to April in spring, because the temperature in spring is relatively low, the germination of seed stem will become slower, so we can choose indoor hotbed to accelerate seed stem germination before sowing. The suitable temperature for germination is about 20 ℃, and then it will sprout after 15 days.

2. You can also choose to accelerate germination outdoors, place the seed stem in a plastic greenhouse of 20-25 ℃, and then wait for 15 days. When the coleoptile turns white, you need to plant the seed stem with bud head into the ploughed land, and then cover it with plastic film, which only needs to be covered between the rows planted with seed stem, and the seedlings can be removed after the seedlings have grown.

Second, timely drainage and irrigation, timely topdressing

1. Pinellia ternata likes to be moist and resistant to fertilizer, but it is afraid of stagnant water, so it is necessary to soak the planting land before planting, which is beneficial to seedling emergence, keep the soil moist during the seedling growth stage, irrigate in time in case of dry climate, and do a good job of drainage in the rainy season. to avoid the death of seedlings caused by too much water in the field.

2. farm manure is mainly applied. In addition to applying sufficient base fertilizer during planting, it is necessary to apply fertilizer twice during the growth of Pinellia ternata, and the first topdressing is carried out from late May to early June. 50 jin of rotten cooked cake fertilizer and 4000 jin of mature human and animal manure were applied between rows per mu.

III. Selection and interplanting of stalk crops

Pinellia ternata is a shade-tolerant crop with strong growth and high yield in shady environment, so it is necessary to choose the gentle slope of half-shade and half-sun, interplant young fruit trees and plant tall stalk crops such as wheat and corn between the border of Pinellia ternata.

Fourth, remove the buds

About 60 days after planting Pinellia ternata, the plant will gradually bolting and blossom, and will consume a lot of nutrients, so in addition to retaining seeds, it is also necessary to remove flower buds in batches in time to promote the concentrated transport of nutrients to underground tubers, which is beneficial to accelerate tuber growth and increase yield.

5. Delay the fall of seedlings.

When Pinellia ternata meets high temperature and strong light, the seedling will fall, and the growth will be suspended, so delaying the seedling falling is the key to the high yield of Pinellia ternata. According to the relevant production experience, in addition to taking proper sunshade during the planting period, there are sprinkler irrigation measures to reduce the light intensity and air temperature, but also spray an appropriate amount of sodium sulfite solution 0.01%, which is beneficial to weaken the intensity of plant respiration, thus delaying the number of seedling falling. To achieve the goal of high quality and high yield.
