Artificial planting

1. Land selection and preparation: it is appropriate to choose sunny, good drainage, deep and loose and fertile loam, full reclamation, deep ploughing of 30cm, rake flat broken soil, make beds, and open drainage ditches.

2. Sowing and raising seedlings: either autumn sowing or spring sowing. Autumn sowing in September when the seeds mature, sowing along with the harvest, the germination rate is high. Spring sowing takes place in late March. Sow the seeds in the seedbed, cover 2cm of fine soil, cover the grass and water. The sowing rate is 1250 / mu 1500 g / mu. The seedlings can emerge 20 days after sowing when the temperature is above 25 ℃, and the cover grass can be removed after emergence.

3. Planting: when the height of the seedling is about 20 cm, it can be transplanted. Hole planting: dig the pit according to the plant spacing of 70 cm and the row spacing of 90 cm. The tree pit length X wide X depth (cm) is 60X 60X 50, and each pit is fully fertilized. One plant was planted in each hole.

Maintenance and management

1. Intertillage weeding: within 1-2 years after planting, weeding is done 4-5 times a year, during which peanuts, soybeans and other crops can be planted. Two years later, it was ploughed and weeded 3 times a year for 4 times.

2. Topdressing: topdressing human feces and urine or urea once a month at seedling stage. After planting, turf mud, compost and barnyard manure were applied once every summer and winter. Cultivate the soil after each topdressing.

3. Pruning: after the trunk of more than two-year-old plants is basically formed, the weak branches, disease and insect branches, withered branches and budding branches from the rhizome should be pruned.

Pest control

It is common for longicorn beetles to eat stems and roots, which can manually capture adults or remove eggs, insert worms with wire to stab the larvae, or soak 80% of dichlorvos solution with medicinal cotton into the bores, seal them with mud and poison the larvae. Zanthoxylum nitidum is used as medicine. It is generally cultivated for 5 years and harvested after 6 years. Dig in winter, wash the sediment, slice it and dry it.
