Plant Chinese prickly ash in late autumn and early winter

Compared with spring sowing, the effect of sowing and raising seedlings of Zanthoxylum bungeanum in autumn is better. Autumn sowing Zanthoxylum bungeanum, do not need to sprout, the seeds germinated naturally, generally in the following year late March to early April seedlings, 10-15 days earlier than spring sowing. In this way, the root system of seedlings is formed early, the ability of disease resistance and stress resistance is strong, and the rapid growth period comes early.

Prepare the land to make beds. Choose the sandy soil with leeward and sunny, deep and fertile soil layer and good drainage as the seedbed. Apply barnyard manure 2000-3000 kg per mu, deep ploughing fine Harrow. Make a bed after soil preparation, with a width of 1 meter.

Seed treatment. Chinese prickly ash seed shell is hard, with oily, waxy, impervious, germination is more difficult, before sowing to carry out degreasing treatment. Soak the seeds in alkaline water solution (1 kg of seeds with 25 grams of alkali powder, add water to submerge the seeds), remove the empty chaff seeds, soak for 2 days, scrub off the oil from the seed coat, remove and dry to sow the seeds. You can also rub it with plant ash to remove the grease from the seed coat.

Open a ditch to broadcast. The seeds can be sown from the end of autumn to before the soil is frozen. Each furrow is 4-5 rows, the ditch depth is 5 cm, and the sowing amount is 10-12 kg per mu. Cover the seeds with fine soil 2-3 cm thick after sowing.

Early spring management. When thawing at the beginning of the next spring, the seeds were suppressed once, so that the seeds were closely connected with the soil, so as to facilitate the seeds to absorb water and emerge seedlings. Take good care of the nursery, do not let people and animals trample inside. Water should be watered in case of drought in early spring. After watering, a few days after shallow hoe to preserve soil moisture, keep the border surface moist and prevent soil consolidation.
