Planting method:
① Seedbed preparation. Padding 8 ~ 10 cm horse manure or broken grass at the bottom of the seedbed, covering it with a layer of soil and treading it flat. At the same time, 70% mepiquat chloride wettable powder of 0.3 ~ 0.6 g/m2 was used for disinfection, and the shed was closed. After sowing, fix the shed on the seedbed.
② Preparation of nutrient soil. Select the soil that has not used herbicides such as Pushing, Bensulfuron, etc., sieve it, and mix it with the decomposed farmyard manure after sieving at a ratio of 7: 2.
③ Bagging and sowing. Put the nutrient soil into a plastic bag of 10 cm× 15 cm, put 20 ~ 30 hydrazine as base fertilizer at the bottom of the plastic bag, fill the pier, cut off the bottom corner of the nutrient bag or tie 2 ~ 4 holes with 8 ~ 10 mm at the bottom for water permeability. The sowing time depends on the local season. Make a hole 3 ~ 4 cm deep in the middle of the nutrition bag with a wooden stick, put down the germinated seeds, and water it once after soil remediation.
