Seeding, breeding and cultivating method of Melia azedarach

Abstract

The invention discloses a seeding breeding and cultivating method of Melia azedarach, comprising following steps: (1), picking fruits from Melia azedarach trees as seeds in late November of the year before seeding, and storing the seeds in dry and ventilated place; (2) selecting a moist and loose land with good drainage as a seedling land, applying a base fertilizer to the seedling land before seeding, and raking to make a seedling bed after subsoiling; (3), subjecting the fruits to bud forcing treatment, ditching the seedling bed for sowing in line, and earthing and watering after seeding; (4), weeding after emergency of seedlings, carrying out thinning when seedlings are 8-10 cm high, and reserving a strong one in each bundle; (5), transplanting the Melia azedarach seedlings on the seedling bed before the Melia azedarach seedlings germinate in spring of the year just after seeding, transplanting the Melia azedarach seedlings to a nursery according to 3m*3m row and plant spacing, and outplanting when the Melia azedarach seedlings are 3 m high and greater than 3 cm in diameter at breast height. The method has simple steps, is easy to implement and enables effective improvements in germinating rate of the Melia azedarach seeds and seeding breeding survival rate.

Description

technical field [0001] The invention relates to a method for sowing and propagating trees, in particular to a method for sowing and propagating neem, belonging to the technical field of agricultural tree cultivation. Background technique [0002] Neem, a well-known species in the Meliaceae plant, also known as Kuling, Jinlingzi, Sandalwood, Senshu, etc.; it is a deciduous tree plant in the Meliaceae family, 10-20m high; the bark is dark brown, longitudinally split, and the old branches are purple. There are many small lenticels; born in the wilderness or by the roadside, often cultivated in the front and back of the house; the plant grows quickly on moist fertile soil, and the soil is not strict, and can grow in acidic soil, neutral soil and limestone areas , is a good tree species for afforestation in plains and low-altitude hilly areas, and it is more suitable to be planted beside village roads; The root bark can drive away roundworms and hookworms, but it is poisonous, a...

Problems solved by technology

[0003] At present, the sowing and propagation process of neem is complicated and diverse, and it is not easy to implement. Moreover, the structure of the neem seed coat is hard, compact, and impermeable, and the germination rate of seeds is extremely low. The survival rate of sown neem seeds is not high, which cannot meet market demand. Simultaneously, the wasted breeding and cultivation time virtually increases the cost of neem propagation
