Magnolia grandiflora field interplanting shrub

In the first three years of Magnolia magnolia seedlings, in order to make up for the shortcomings of large investment and no benefit output of planting trees in the early stage, small shrubs can be planted, such as small shrubs, such as Euonymus tomentosa, Ligustrum lucidum, Berberis amurensis and so on. During the period of interplanting seedlings in the first three years, there were 6000-7000 seedlings per mu, with an average of 0.5 yuan per plant, and the income was more than 3000 yuan. After the fourth year, Magnolia magnolia grew to 5-6 cm, which could be sold at intervals of about 80 yuan per plant. Every year since then, there will be a profit from the sale.

Key points of cultivation: when planting one-year-old seedlings of Magnolia magnolia, the plant spacing is 1.2-1.3 meters, the row spacing is 1.5-1.7 meters, and 300-400 plants can be planted per mu, one row for every two plants. When interplanting seedlings between the borders of Magnolia magnolia, the plant spacing is 15-20 cm, the row spacing is 25-30 cm, and 6000-7000 plants can be interplanted per mu.

Management measures: regular ploughing, weeding and fertilization, extra-root topdressing 2-3 times a year, compound fertilizer once from March to April, urea once from May to June, and once more at the end of July; urea can be applied to seedlings once a year in spring, 20 kg per mu. In April, attention should be paid to the prevention and control of leaf roll moths that harm the buds and leaves of Magnolia. 98% crystal trichlorfon can be sprayed 1000 times for 2-3 times.
