The most commonly used propagation method of Toona sinensis is to sow seeds. So how to plant Toona sinensis seeds? Let's introduce it to you by the editor.

1. Harvest seeds

The fruiting period of Toona sinensis is relatively long, and it will not enter the fruiting period until about 8 years after planting. When collecting seeds, we should choose Toona sinensis, which has been growing strongly for about 20 years, has high seed set and is free of diseases and insect pests as the mother plant. When the fruit changes from green to dark, it means it is ripe. At this time, it can be harvested. After harvest, the fruit should be exposed to the sun for a week or so. Until the moisture of the fruit evaporates and the pericarp cracks to reveal the seed. Then the impurities are removed and stored in a storage bag, and the germination rate of fresh seeds harvested in that year can reach about 85%.

2. Land selection and preparation

After seed collection, we have to choose a soil with sufficient water and sandy soil as the planting plot, which is very sad for drainage and irrigation. Then in the spring, the soil will be fine raked, and then according to the soil area to control the specifications of the border, to prepare the border for planting. After making the bed, it is necessary to apply sufficient base fertilizer, which is dominated by rotten farm manure and supplemented by phosphate fertilizer. Pay attention to control the dosage, keeping farm manure at about 1500 jin / mu and phosphate fertilizer at about 50 jin / mu. And properly spray trichlorfon and other insecticides to eliminate pests. Then plough the soil again, fully mix the soil with pesticides and fertilizers, and water enough a week or so before sowing.

3. Seed germination

After the preparatory work is done, it is necessary to accelerate the germination of the seeds. First of all, about a week before sowing, put the seeds in warm water of about 50 degrees and stir for about 5 minutes. Then soak the seeds for a day or so. After soaking the seeds, remove them and wash them, then put them in wet sand or a bag of seeds to ensure sufficient moisture, and then put the bag at a temperature of about 25 degrees to promote germination. Wash the seeds once a day during the budding process. When more than half of the seeds are cracked and exposed, they can be sown.

4. Sowing seeds at the right time

Half of the sowing time of Toona sinensis seeds is about 3-4, so we should finish the sowing work before Grain Rain. The sowing method of Toona sinensis is generally strip sowing, first of all, the sowing ditch should be dug on the border surface, and the row spacing should be controlled at about 36 cm. Then water the soil in the sowing ditch. When the water is soaked through the soil, the seeds are spread evenly into the sowing ditch, cover a layer of fine soil after sowing, and then pour enough water. When the seedlings are successfully unearthed, it is necessary to do a good job in seedling management and grow about 5 true leaves and time seedlings.

The above is a brief introduction to how to plant Toona sinensis seeds. The growth cycle of Toona sinensis is relatively long. Therefore, we should do a good job in management, strengthen planting techniques, and maintain a certain degree of patience. That's all for today's introduction. This article is for reference only.
