When sowing, 70% of nitrogen fertilizer and total phosphate fertilizer and potassium fertilizer were used as base fertilizer at one time. The other 30% of nitrogen fertilizer was applied at roots 15 cm when the plant grew to 10 leaves. Seeding techniques: where conditions permit, it is advisable to sow or sow seedlings with a sowing volume of 2 kg/mu. Seeds and fertilizers are sown separately. Note that the fertilizer should be applied 3 to 4 cm below the seeds. This will not only prevent the burning of seedlings, but also promote the roots of the seedlings. Unconditional can be used to open the ditch with small rakes, hand-sprinkled seeds, sowing volume of 2.5 ~ 3 kg / acre.
