The latest course of Zanthoxylum bungeanum cultivation techniques and methods

Zanthoxylum bungeanum is a kind of shrub with high economic value, which is an important woody oil and spice tree species. Because of its strong adaptability, wide distribution and large income, it is deeply welcomed by the masses, but Zanthoxylum bungeanum is not resistant to waterlogging and afraid of storm, so the seedling land should not be planted in the mountain top, tuyere, alpine and cold areas.

Seedling raising technique

1. Seed collection. There are many varieties of Zanthoxylum bungeanum. When collecting seeds, plants over 10 years old with strong growth, early fruit, high yield and good quality should be selected as the mother tree. The seeds should be dried and can not be exposed to the sun to prevent high temperature damage and loss of germination power.

2. Seed treatment. After the seeds are dry, remove the blighted seeds with a wind separator. Soak in lye or washing powder water (50 grams of 5kg seed with alkali or washing powder) for two days, scrub by hand to remove fat, and then rinse with clean water.

3. the arrangement of the nursery. The nursery land is best selected in the yellow loam or sandy soil with drainage and irrigation conditions, first ploughing, combined with ploughing mu application of accumulated fertilizer 3000kg or ammonia hydrogen phosphate 50kg, and then rake flat ridge or border.

4. Sowing time and method. It is generally carried out in winter and spring and before the Beginning of Spring, and the sowing method can be border sowing or semi-high bed; the sowing rate is 20kg per mu for selected seeds and about 40kg per mu for unselected seeds.

5. Nursery management. After sowing, it is necessary to keep the seedling bed moist. When the seedlings are unearthed and grow to 4cm-5cm, the seedlings can be interspersed, and the suitable distance between seedlings is 10cm-12cm. Pepper seedlings when young, to use artificial or chemical weeding, can not use hoe hoe, so as not to hurt the roots of the seedlings. Urea can be applied 3-4 times from June to July, each time at an interval of about 15 days, 5-7.5kg per mu each time, or about 300kg in feces and urine of acquaintances. When the seedlings grow above 60cm, they can go out of the nursery for afforestation.

Land preparation and afforestation

Different methods of land preparation are used in different types of afforestation land. Generally, the large pit is used for afforestation, and when the slope is steep, the horizontal ditch is used for afforestation. The specification of the pit should be more than 30 × 30 × 30cm. Farm manure and calcium magnesium phosphate fertilizer should be used as base fertilizer in the pit.

1. Afforestation specification. The row spacing is 3 × 4 m, 56 plants per mu.

2. Afforestation time. It is usually carried out in winter and spring before the Beginning of Spring. Areas that are too dry in winter and spring can also be carried out in the rainy season, but they should be completed before the Beginning of Autumn, and some leaves should be subtracted when planting to reduce evaporation so as to improve the survival rate.
