"auspicious fruit" how long will it take for dragon fruit seeds to germinate? How many years will it bear fruit? How do you plant it?

Fire dragon fruit, also known as jade dragon fruit, green dragon fruit, is a common tropical fruit in Guangdong, Guangxi, Fujian and other places. After eating, many people will plant the black seeds in flowerpots. How long will the dragon fruit seeds germinate? How many years will it bear fruit? How do you plant it?

How long will it take for dragon fruit seeds to germinate?

Pitaya seeds do not need to soak in water, sow directly, good germination, generally 3-4 days after planting will germinate, sowing without covering the soil, but the seeds as far as possible in full contact with the soil. In general, sowing requires a peritoneum to maintain humidity and temperature.

Second, how many years have the dragon fruit seeds been planted?

The dragon fruit begins to blossom and bear fruit 12-14 months after planting, and can blossom 12-15 times a year. April-November is the fruit-bearing period. The fruit matures 30-40 days after flowering, and the single fruit weighs 500-1000g. It produces more than 20 fruits per column in the second year after planting, and reaches the full fruit stage in the third year. The per unit yield can reach 2500 kg / mu.

Third, how to plant dragon fruit seeds?

1. When will the seeds be planted?

The dragon fruit can be planted all the year round, but it can not be deeply planted, it can be implanted about 3 times deep, and the soil should be kept moist at the initial stage. It began to blossom and bear fruit 12-14 months after planting, and the fruit-bearing period was from April to November. The fruit was ripe at 30-40 days after flowering, and the single fruit weighed 500kg / 1000g. It produced more than 20 fruits per column in the second year after planting, entered the full fruit stage in the third year, and the higher management level, the per unit yield could reach 2500 kg / mu.

2. What are the high-yield planting techniques of dragon fruit?

(1) emergence of seedlings. Sprinkle the seeds evenly into a flowerpot with soil and sprinkle with some water. Be careful not to pour water directly. Then cover it with cling film. Remember to lift the cling film every other day and sprinkle it with a spray can. If you don't use it for a week, the seeds will begin to sprout, and then the cling film can be removed. When the seedlings are about the same, they begin to plant separately.

(2) planting methods: pitaya can be planted in a variety of ways, which can be planted by climbing the wall or in a shed, but column cultivation is the most common, which has the advantages of low production cost and high land utilization rate.

(3) planting specification: the row spacing of dragon fruit with double-season column is 1.5 × 2 meters. According to the calculation of 4 seedlings planted around each column, 750 plants can be planted per mu. But pay attention not to deep planting, implant about 3 cm deep, the initial should keep the soil moist.

(4) reasonable interplanting: red dragon fruit has poor self-pollination compatibility, low rate of self-pollination, small fruit, poor marketability, and needs white meat dragon fruit pollination. Interplanting about 10% white meat type dragon fruit can significantly improve the seed setting rate.

3. Planting conditions:

(1) temperature: lukewarm dragon fruit is not afraid of high temperature and low temperature, the average annual temperature is not less than 18 ℃, the average temperature in January is not less than 8 ℃, the extremely low temperature is-3 ℃, the duration is not more than 6 hours, the optimum growth temperature is 25: 35 ℃, the temperature below 10 ℃ and above 38 ℃ will stop growing.

(2) soil: Dragon fruit has extensive adaptability to soil, and can grow well in mountain, dry land, semi-dry land, stony mountain, wasteland and waterlogged low-lying land, especially the dragon fruit grafted with local ruler, its adaptability is more extensive.

(3) moisture: pitaya is a drought-tolerant plant, but it needs plenty of water to grow. if the pitaya is short of water for a long time, it will cause the growth of pitaya to stagnate, and even the original stout fleshy stem will slowly wither.

(4) Light: the dragon fruit is a typical solar plant, which likes warm direct sunlight. If the sunlight time is long and the sun is sufficient, the photosynthesis is especially exuberant, the flesh stem is stout, the color is thick and green, the flowers are many and fruits are large and fruitful, otherwise, the amount of fruit is obviously reduced.

(5) Fertilizer: the dragon fruit grows fast, and the fertilizer needed in the whole growth cycle must be sufficient. Sufficient nitrogen fertilizer should be supplied in the early growth stage to help the plant grow fast, tall and strong. In the middle and later stages of plant growth, more balanced application of nitrogen, phosphorus and potassium fertilizer should be applied to increase plant photosynthesis.

4. How to repair plastic surgery?

The main results are as follows: (1) Seedling stage: during the seedling growth, one strong upward branch should be retained, and the other lateral branches should be cut off in time, which is beneficial to concentrate nutrition for the strong branch to climb up quickly.

(2) growth stage: when the plant grows to 1.5 meters high, it can divide into more than 3 naturally drooping branches, and when the branches are mature and in the period from April to November, these drooping branches will have a chance to blossom and bear fruit. It is observed that the upper and middle branches, especially the drooping branches, have a higher flowering and fruiting rate, while the middle and lower branches rarely bloom. From the analysis of the distribution position of the branches, the growth potential of the upper branches is usually larger than that of the middle and lower branches, which may be caused by the top dominance, but the upper branches are not easy to be bound because of their high position, and their growth potential is strong, but the mechanical strength of the tissue is poor. It is often easy to be blown off by the wind. The upper branches can gradually adopt the methods of bracing, pulling, hanging and binding, and gradually let them droop to reduce wind damage after the branches mature and begin to blossom.

(3) after fruiting: each plant can arrange the branches of 2pare 3 as fruiting branches, and the other branches of 1x3 can erase the buds or flowers, reduce the growth angle of the branches, promote their realistic vegetative growth, and cultivate them as strong preparatory fruiting branches. If some plants bear more fruit, it is less likely to form a large number of concentrated flowering branches in the next year, and after forming a large number of strong branches at the base of the plant, thinning can be used to thinning and leaving strong branches, or cutting weaker branches to promote it to develop into strong vegetative branches.

(4) after fruit harvest: replanting and pruning should be carried out, that is, individual plants with weak growth should be dug out and new seedlings should be planted, and the top or weak branches that have borne many fruits should be cut off, so that the sturdy branches left can grow new branches again, so as to ensure the yield and quality in the coming year.
