1、育苗 (1)种子处理:苦楝果核坚硬,为了缩短发芽时间,出苗整齐,在播种前必须进行催芽处理。可在冬季沙藏3个月以上。也可在播种前用50℃温水浸种,放置两天,然后混沙增温催芽,促使种壳开裂,但不如沙藏发芽整齐。 (2)播种:苦楝可春播也可冬播,以春播较多。用大田式或苗床式育苗均可。行距40cm,开沟5-6cm,在沟内撒播或点播。点播株距15cm,覆土2-3cm,覆土后轻轻镇压,使种子与土壤密切接触。每亩播种量20-25公斤。 1, nursery seedlings (1) seed treatment: Meliaceae nuclear hard, in order to shorten the germination time, emergence and tidy, must be germinated before sowing. Sand in the winter more than 3 months. Can also be soaked with 50 ℃ warm water before sowing, place two days, then mixed sand warming sprouting, prompting the seed shell cracking, but not as neatly distributed sand reservoir. (2) Seeding: Meliae can be sowing can also be winter sowing, spring sow more. With field or seedbed nursery can be. Row spacing 40cm, ditching 5-6cm, in the trench broadcast or on-demand. On-demand plant spacing 15cm, 2-3cm soil cover, after the soil gently suppressed, the seeds and soil in close contact. Sowing 20-25 kg per acre.
