Where can I sell catalpa seeds? What are the methods of raising seedlings?

When it comes to catalpa trees, friends who have lived in rural areas for a long time are probably very familiar with them. Food materials can be seen in mountains and forests, with high ornamental value, fruit can be used medicinally, and wood is a good material for furniture. So where can I sell catalpa seeds? What are the methods of raising seedlings? Friends who want to know, please read the following!

First, where can I sell catalpa seeds?

Now there are still many places to sell catalpa seeds. Generally speaking, there are local seed stores and flower markets, as well as some e-commerce network platforms, so you can choose more reliable stores to buy. Our rural information network also has catalpa seeds to provide, and after-sales service is guaranteed.

Second, what are the seedling methods of catalpa seeds?

1. Seed collection

The seeds of catalpa generally become hot from September to October and often do not fall through winter, and the seeds can be collected in November. A fine single tree with good growth, straight stem shape, open crown and full fruit is selected as the mother tree for seed collection. After the recovered fruit is dried, the pure seeds can be obtained by removing the shell and other sundries. The seeds are oval, about 0.8cm long, with white hairs at both ends, and the germination rate is about 40%. Put the seeds in a cloth bag and store them in a sterilized, low-temperature, dry and ventilated room.

2. Nursery site selection and soil preparation

Catalpa is a small seed with high requirements for seedling rearing, so choose sandy loam with loose, fertile and breathable soil, good water conservation and drainage performance, and free of underground pests and bacteria. The sowing land had better be ploughed one to three times in autumn and winter, and 5% phoxim granule of 2-3ks per 667m2 was given. The medicine was added to the fine soil, sprinkled into the nursery, and then ploughed to eliminate underground pests, so as to promote soil weathering, store water and preserve soil moisture, and eliminate weeds, diseases and pests. In spring, a border with a width of 1m and a length of 10m was made and base fertilizer was applied. 15-20kg ferrous sulfate was applied per 667m2, mixed with 20 times fine soil, and evenly sprinkled into the seedling bed to control seedling blight.

3. Sowing seeds

Catalpa seeds germinate easily and sow for a long time. Sow as early as possible when the soil temperature is suitable in spring to increase the growth time of seedlings. Fill with enough bottom water before sowing. Catalpa seed germination rate is low, the amount of seed can be larger, generally 5 to 10 grams per square meter. When the number of split-mouth seeds of mixed sand germination seeds reached more than 30%, the 1 m wide border sowed 4 ridges, sowed 10cm, sowed soil thickness about 0.5cm, and suppressed in time with the degree of micro-buried seeds. After sowing, cover the grass to cover the shade, spray water at the right time, keep the bed moist and unearthed in 7-10 days. The use of strip sowing is not only beneficial to ventilation and light transmission of seedlings, but also easy to manage.

4. Tending and management of seedlings

In the process of seedling growth, strengthening the tending and management of seedlings is the key to cultivate strong seedlings. Catalpa seedlings grow slowly in the first month, so it is necessary to keep the nursery moist and pay attention to loosening the soil and weeding to promote the rooting of the seedlings. After 6 true leaves enter the fast-growing stage, it is necessary to plant seedlings as early as possible. It is appropriate to keep 120 seedlings per square meter, ask the seedlings to be small and large, remove the inferior and retain the good, keep the density sparse, the whole seedling equidistant, and carry out it in cloudy and rainy days. Combined with inter-seedlings, the missing plants were treated with supplementary seedlings to ensure the uniform distribution of seedlings. The whole seedling stage should be topdressing 2-3 times, the first time in late May, this fertilization should be a small amount of fine application, urea 0.15kg per 10m2 border topdressing, hoe a shallow trench in the seedling row, cover the soil, and water after topdressing; the second fertilization should be in late June, the same method topdressing urea 0.3kg per lorn2 border. The third fertilization should be applied before the second growth peak of seedlings, that is, in late July, compound fertilizer 0.3kg should be applied in each 10m2 ditch between two rows of seedlings. In order to meet the late growth needs of seedlings, accelerate the Lignification of seedlings, and improve the cold resistance of seedlings. The seedlings can be planted in human trench after defoliation in autumn, and then planted in the following spring, and the height of one-year-old seedlings can reach 60-80cm.
