How to grow kapok seeds
This article will give you a detailed explanation of how to grow kapok seeds and the plant breeding experience of some tips for maintaining kapok seeds. Next, this website will introduce it to you.
The kapok tree is a large deciduous tree belonging to the kapok family, also known as Panzhihua, Molian, red jasmine, Molian flower, red cotton, mottled awns, etc. It is a large deciduous tree growing in tropical and subtropical regions, with a height of 10~20 meters. The kapok tree is a deciduous tree in the kapok family. Kapok blossoms first from February to March every year and then grows leaves. The corolla is five-petaled, orange or orange-red, and usually grows in early spring, appearing earlier than the leaves. It used to be an economic tree species, but now it is a flower tree for viewing. Domestic cultivation is mainly carried out in Hainan, Fujian, Guangxi, Guangdong, Guizhou, Sichuan, Yunnan and other provinces and regions. Hainan kapok has been open to price increases from south to north since the Spring Festival. February and March of early spring is the season when kapok is in full bloom, and it grows beautiful. February of early spring is the day when kapok trees are planted. In some places where kapok trees are planted, brilliant flowers will bloom one after another. Looking at it from afar, the orange-red color of the tree looks particularly vibrant.
1. Breeding methods of kapok: The breeding methods of kapok include seed reproduction, layering reproduction and tissue cultivation reproduction. Seed reproduction is commonly used.
1. Seed reproduction: From mid-June to mid-December, the pods mature one after another. Collect the ripe fruit pods from September to October, place them in the sun to expose them to the sun. After cracking, the seeds are peeled off. They can be sown as they are picked, and the seedlings can survive the winter. They can also be stored and sown in the spring of the following year. Sowing in the middle and late March of spring. Before sowing, soak in warm water at 60 ° C before sowing, and continue to soak for 12 hours after cooling. Germination is rapid. Generally, germination begins three days after sowing and ends within one week. The germination rate is about 60%. Using the drill sowing method, the seedling growth rate is medium. Nitrogen fertilizer is applied 2 - 3 times at seedling stage. After October, the application of nitrogen fertilizer is stopped and the application of potassium fertilizer is consistent to promote early lignification. Pay attention to covering and preventing frost in winter. One-year-old seedlings can be planted in the nursery., two-year-old saplings can bloom for viewing.
2. Layered propagation: Kapok is a tall tree and mainly adopts high-pressure propagation method. The method is to select 2-4-year-old branches with relatively vigorous growth on the crown. At a distance of 20-30 cm from the base branch, first peel off half of the two by a circular peeling method. One to two-thirds of the skin layer, then mix some high-quality flour fertilizers such as compound fertilizers with fertilizer mud and wrap it around the wound to form a ball. The outside is wrapped with plastic film to moisturize. The high-pressure time is usually carried out in February to March in early spring. After white roots can be seen growing through the plastic film from August to September, the batten will be sawed off from 3-5 cm below the batten. The removed batten must be planted immediately.
3. Cuttage propagation: Generally, cuttage is carried out during the period when kapok flowers are growing vigorously from April to May. After cuttage, moisturize and avoid standing water, cover the shade and avoid direct exposure to the sun, and keep the temperature at 25-27 ° C for easy survival. The cuttage method is to select well-growing branches from healthy plants and cut them, cut healthy branches with a length of about 8-15 cm, and cut them in a moist sandy soil matrix, preferably keeping the temperature between 15-30 ° C., just pay attention to shade and moisturize. Insert one-half to two-thirds of the cutting into the hole obliquely, compress the soil tightly, and water it once. Cover the shade and moisturize after cutting, and you can take root quickly. Generally, the survival rate of cuttage propagation is relatively low. In order to improve the rooting rate of cuttage, plant growth hormone can be used to treat the cuttings of Camellia japonica during cuttage, which has obvious effects on promoting rooting. Commonly used growth hormones include indolebutyric acid, indoleacetic acid, naphthylacetic acid, 2,4-D, rooting powder, etc., all of which have a good effect on promoting rooting.
2. Cultivation: Kapok can be cultivated in courtyards, parks or as street trees. Kapok is generally carried out in spring before the roots of seedlings have yet to sprout, with a row spacing of 1.2 meters ×1.2 meters. It is sprinkled with root-fixing water on the day after planting. Adhere to the principle of "eliminate early, eliminate small and eliminate all" and remove weeds in a timely manner.
3. Management: The management of kapok is relatively simple. Fertilization is generally applied three times after transplantation. The first fertilization is carried out in mid-April, the second fertilization is carried out in mid-July, and the third fertilization is carried out in mid-September. Hole application method is used to dig symmetrical holes 30 cm away from the seedling trunk, the holes are deep enough to the seedling root distribution layer, and 0.5 kg of compound fertilizer is applied to each plant. In the future, fertilization will be carried out according to the growth of kapok flowers. Under normal circumstances, no more fertilization will be carried out.
