How to plant Moringa oleifera seeds?

Moringa oleifera is generally propagated by seeds, and it is best to use fully mature seeds harvested in the same year. The seed germination rate can reach more than 90%, and the germination rate of seeds stored for too long will be reduced. The germination rate of seeds stored routinely for one year at room temperature is only about 60%. Seeds can be sown all the year round in the tropics, but the best sowing time is from the end of February to early March. Let's take a look at how to plant Moringa oleifera seeds.

Preparation of Moringa oleifera seedling bed

The Moringa oleifera seedbed selects land close to the planting site, calm wind and convenient water source, remove weeds, stones and other sundries, level the land, use red brick to build a sprouting bed with a length of about 600 × 80 × 40 cm, and then put it into the river sand with a thickness of 20-25 cm. A shading net of about 40% is erected above the seedling bed, and the shade is 1.7 meters high, depending on the actual topography of the seedling bed.

Moringa oleifera seed treatment

Before sowing Moringa oleifera seeds, remove defective seeds, immature seeds and moldy seeds, pour the selected seeds into the prepared potion and soak for 15 hours for 17 hours. Fungicides such as 800-1200 times liquid carbendazim, Luheng No. 2 and Baijuqing can be selected. When sowing, flatten the sand bed with a straight stick, press the seeds into the sand by hand, the spacing is about 2 cm, and the sowing depth is 1.5-2 cm. Too deep or too shallow will reduce the emergence rate. Sow the seeds with water, then cover them with agricultural film. The seeds of the same year can sprout in 5-7 days, and the seeds of the second and third years sprout 3-5 days later.

Raising seedlings in bags of Moringa oleifera

The nutritive soil of Moringa oleifera seedling bag is required to be fertile and loose. It is prepared with pure land, rotten high quality organic fertilizer, calcium magnesium phosphorus and compound fertilizer according to the ratio of 100 ∶ 25 ∶ 3 ∶ 2. The specification of nutrition bag is 12 × 17 cm, and the seedling bed should be low moisture content, about 80 cm wide. The bagging requirements are tight and full. Put the nutrient bags containing nutritious soil on the seedbed, and the bags are close to each other. About a week after sowing into the sand bed, the seedlings began to unearth. when the cotyledons were just unfolded, they were moved into an arranged nutrition bag. Be very careful not to hurt any part of the seedlings. After planting, water thoroughly with 800 times Luheng 2 liquid or other fungicides as soon as possible.

Management of Moringa oleifera seedlings

After Moringa oleifera transplanting survived, 800 times Luheng No. 2 and other fungicides were poured every 15 days, and insect pests were observed at any time, spraying medicine at the right time, often drenching water, keeping the soil moist in the bag, but not too much water to prevent rotting roots. When the seedlings grow to 5 or 6 leaves, the shading net can be removed, and the plant height can reach more than 40 cm in 4 weeks, which can be timely implanted into the field. If the seedlings are planted too late, the survival rate will be affected by the penetration of the main root into the bag.
