How to grow kapok planting methods and matters needing attention

Sometimes you will see a kind of red flower on the road, very good-looking, in fact, it is kapok, its plant is very tall, has a high ornamental value, and it is usually sown with seeds, but generally seeds planted in this way need to be treated, so let's take a look at how it is planted.

How to grow kapok

Kapok seeds are easy to float around with cotton hair, so if you want to collect seeds in time, spread out and expose the seeds after harvest. If stored for too long, the germination rate will decrease or even lose the ability to germinate, so it is best to sow with picking. Before sowing, disinfect the seeds with 0.3% potassium permanganate solution, then rinse them with clean water, sow them after drying, and prepare the soil carefully before sowing. Sowing is used to sow, after sowing, cover the soil 2 cm thick, slightly suppress so that the seeds are closely combined with the soil, and then sprinkle with enough water, and then sprinkle water once or twice a day to keep the soil moist.

Planting method of kapok

1. Propagation time: kapok should be grafted from March to March and from July to July. When the temperature rises quickly from March to March, kapok begins to sprout and shoots, so the grafting is easy to survive.

2. Growing soil: kapok is not demanding on soil, sandy soil or clayey soil is suitable, acidic soil is more resistant to drought, but also slightly resistant to water and moisture, the requirement for fertility is not very high, generally medium fertility, high phosphorus and potassium fertilizer soil.

3, growth humidity: kapok growing season to keep the soil moist, or directly planted into a watertight basin, can avoid the trouble of watering every day, when the temperature is higher, but also pay attention to foliar spraying to maintain humidity.

4. Growth temperature: kapok is not cold-resistant, open field in East China can survive the winter with a little protection, and the winter temperature is not lower than 5 ℃.

5, growth light: kapok adapts to a wide range of light, can grow well in all-day or semi-shady places, and avoid scorching sun exposure.

Planting matters needing attention

1. Application of fertilizer: the requirements for soil are not harsh, sandy soil or clayey soil is suitable, acidic soil is more resistant to drought, but also slightly resistant to water and moisture, the requirement for fertilizer is not high, generally medium fertility, high phosphorus and potassium fertilizer, it is appropriate to apply rotten cake fertilizer or garbage as base fertilizer when planting, and topdressing phosphorus and potassium fertilizer before flowering and in full bloom.

2, watering key points: kapok in the growth process, we should pay attention to keep the soil moist, timely watering on it.

3, pruning essentials: during the growing period, kapok should remove the residual branches and flowers in time, control the growth of the overgrown branches by picking the heart, promote the new branches, make the plant perfect, have a good crown, and prolong the flowering period.

Propagation mode of kapok

1. Sowing and reproduction

Every October, the fruit is gathered in clusters, harvested and stacked in a cool place. After a few days, spread out to dry, the fruit split to remove, remove floc sundries, dry after storage. Sow seeds from February to March in early spring and sprout before sowing, either by strip sowing or sowing. The seed consumption per hectare is 45-60kg.

After sowing, we should strengthen the management according to the general measures of raising seedlings, and when the seedlings grow to 5-6cm, we can carry out transplanting and separate bed cultivation. The annual seedlings are up to more than 50cm and will be planted in the nursery after autumn or in the following spring.

2. Cuttage propagation

Before blooming and sprouting in early spring, collect sturdy 1-2-year-old branches with full winter buds, cut them into 20cm long cuttings, plant them densely in the sand bed, soak them with water and keep warm, and then move them into the nursery bed after the long leaves have roots, or bury them with larger branches (diameter 5~10cm), dry length 80~100cm, plant distance 80cm, pit depth 30cm, first pour water at the bottom of the pit, mix it into mud, put the dry cuttings in the hole, fill the soil and step on it, and avoid hard insertion. So as not to damage or break the plug to affect survival.

After burying and moisturizing, too many sprouts and axillary buds should be removed after survival, and a strong sprout should be retained to grow upward so that it can form a good trunk and can be planted in the nursery for 1-2 years. Planting should be sparse but not dense, and it is not suitable for continuous planting, generally for isolated planting or row planting, with a distance of 8m × 10m or more. Planting should be dug big ridge, put enough base fertilizer, colonized with soil mass from February to March, drenched with fixed root water, fertilized 2-3 times a year in the first 3 years to promote its growth.

It seems that in addition to sowing, kapok can still be propagated by cuttings, and we can choose the way we like to plant it. Although the method of planting kapok is relatively simple, the key to planting lies in its nursing. Fertilization, watering and pruning are the key, and we have to do it carefully every step.
