This fruit has many benefits for the human body when eaten and is high in nutritional value, so many farmer friends also grow it at home. So how do you select pomelo seeds? What are the seedling-raising methods? Below, the editor will tell everyone!
1. How do you select pomelo seeds?
For pomelo seeds to germinate, good seeds must first be selected. The surface must not have cracks, and plump, full seeds should be chosen as much as possible. The surrounding environment has very high temperature requirements. They can germinate within the range of 15-18°C. If the temperature is on the low side, it will be difficult for them to germinate. Before planting, treat the seeds first, choose loose, soft sandy soil, and place the seeds in a flowerpot with the pointed end facing down.
2. Pomelo seedling-raising methods
1. Dig drainage ditches around the seedbed
Drainage ditches must be dug around the seedbed, which makes timely irrigation and drainage very convenient. The seedbed must be arranged in an east-west direction, generally 120 cm wide and 20 cm high, with ditches 40 cm wide; the length can be decided according to the terrain. The bed surface must be level, and the soil particles must be fine, crumbly and soft. A few days before sowing, put in 3,000 jin of farmyard manure and 300 jin of plant ash fertilizer and mix them evenly with the surface soil, then sow the seeds. After growing from September to December, sowing can also be carried out; at this time, the seeds can be stored in sand until the next spring before sowing.
2. Promote seed germination
When sowing, first open appropriate furrows in the ground, with a distance of 10 cm between each row, and the amount of seed used per mu is about 30 jin to 37 jin. About 60,000 seedlings can come out. After sowing, cover with about 10 cm of dry soil, then cover the ground with straw or weeds. Water to keep moist. In places convenient for irrigation, a round of clear water can be applied, allowing it to seep into the ground. When dry, pay attention to the frequency of watering and always keep the seedbed moist, which can promote seed germination. After the young seedlings emerge, uncover the covering grass as soon as possible.
3. Keep the seedbed moist
After the seedlings emerge, the seedbed must always be kept moist, but too much water must not be allowed to accumulate in it. When the young seedlings grow to two leaves and the leaves turn dark green, fertilizer must be applied in a timely manner. In the early stage, use less fertilizer and increase the number of fertilizations, fertilizing about once every 10 days, for about 7 consecutive fertilizations. In the later stage of growth, be sure to reasonably control the number and amount of fertilizing according to the growth of the young seedlings, mainly using poultry manure or quick-acting ammonia fertilizer.
4. Growth management
When fertilizing, some plant ash fertilizer, or phosphate and potassium fertilizers such as superphosphate, can also be used. Its growth management generally lasts one year, and the young seedlings can grow to 30-50 cm tall. At this time, they can be planted directly or used as rootstock seedlings for grafting. During the seedling stage, be sure to pay attention to moisture; do not add too much. After watering, also pay attention to observing the humidity in the air. Also pay attention to promptly removing weeds from the seedlings, thus reducing competition between weeds and seedlings for nutrients. When using direct sowing for planting and seedling raising, be sure to pay attention to correct management methods.
