Planting technology of bamboo emperor grass? When do you plant it?

Pennisetum is a common perennial herb with high ornamental and ecological value. If you want to grow Pennisetum, you can follow the following steps:

1. Land selection and soil preparation: Select the land with fertile soil, abundant sunshine and good irrigation and drainage conditions as the planting land of Pennisetum. When preparing soil, we should dig deep into the soil, remove weeds and stones, finely divide the clods, sprinkle enough farmyard manure as base fertilizer, and finally ditch and plant.

2. Seeding and seedling raising: Pennisetum generally adopts asexual propagation, that is, it is planted by using stem nodes. Seedling should be raised from stem nodes before planting, and then transplanted when the seedlings grow well. Seedling raising time is generally selected from February to May every year, and the best time is around March. Stem nodes need to be mature, healthy and free from pests and diseases, and each node needs at least one bud point. Put the stem nodes into the soil obliquely to keep the soil moist. Generally, seedlings can emerge in about 7 ~ 10 days.

3. Scientific planting: The planting density of Pennisetum needs to be analyzed according to the planting purpose. Generally, 2000 ~ 3000 plants can be planted per mu, with a row spacing of 60 cm and a plant spacing of 20 ~ 30 cm; Or 800 ~ 1000 plants can be planted per mu, with the row spacing of 90 ~ 100 cm and the plant spacing of 30 ~ 50 cm. When planting, it is necessary to water the roots to keep the soil moist. Generally, it is not necessary to water in rainy days, and it needs to be watered every 2 to 3 days in sunny days. At the same time, it is necessary to check the survival of transplanting in the field, replant seedlings in time, and ensure the cleanliness of the field.

4. Field management: Field management is needed after planting, including watering, weeding and fertilization. Water needs to be moderate, and water needs more in sunny days. Generally, water should be watered once every three days, moderately on cloudy days, and timely drained in rainy days to avoid drowning of yellow clover caused by accumulated water in the field. When weeding, intertillage weeding is carried out irregularly to promote plant growth. When applying fertilizer, topdressing should be carried out on the basis of sufficient base fertilizer, mainly nitrogen fertilizer or manure.

5. Pest control: Pennisetum may be attacked by pests and diseases during its growth period, so it is necessary to find out in time and take corresponding measures to prevent and control it.

These are the steps of planting Pennisetum. To thrive, Pennisetum needs diligent management, regular watering, weeding and fertilization.
