Planting techniques and management of gardenia jasminoides Ellis

The planting techniques and management of Gardenia jasminoides Ellis are as follows:

First, technology:

1. Land selection and preparation.

Alluvial loam, purple loam and gravelly soil with deep plough layer, fertile soil, loose soil and convenient irrigation and drainage are suitable for selection. Heavy clay and saline-alkali soil are not suitable for planting. After the land is selected, it should be turned deep before winter to freeze it.

2. Planting. ?

According to the plant spacing of 1x 1.5m, plant 400 plants per mu in the same way as planting trees.

Second, management:

(1) After planting, especially strengthen intertillage weeding and keep it more than twice a year. Intertillage weeding should be shallow, combined with rhizosphere soil to prevent freezing and moisture in winter.

(2) After planting, the buds are pruned 1 year, and all the buds below 30 cm of the trunk are erased to ensure that the tree is small and tree-shaped, and then the tree is pruned into a well-defined and hollow crown according to the growth of the tree.

(3) At the end of March and the beginning of April, apply 3-4 kilograms of urea per mu to lay a nutritional foundation for flowering. At the end of June after flowering, 4-6 kilograms of compound fertilizer should be deeply applied per mu. At this time, nitrogen fertilizer should be avoided to prevent excessive germination of summer shoots.

(4) As a result, the website moves faster. Before and after the solar term in beginning of autumn, chemical fertilizer was re-applied to flower buds, with 6-7 kilograms of urea and 200 kilograms of excrement and urine water per mu. The key to increase production is to apply this fertilizer well. After intertillage and weeding in winter every year, temporarily apply urea 10-20kg and phosphate fertilizer 30-40kg per mu to supplement nutrition, so that it can survive the winter safely.
