How to grow strawflowers? Planting methods and care tips

Water spinach is a vegetable we often eat. It is delicious and easy to cultivate. It is very suitable for home growing. Just one flower pot is enough to grow it. Both the cutting and sowing methods can be used to grow potted vegetables. How can we grow a pot of water spinach? ? This is the method for growing potted water spinach in pots.

1. Water spinach cuttings

In fact, it is very simple. We buy water spinach from the vegetable market, and after proper handling we can carry out the cutting operation. It is easier to see results than sowing. The following are water spinach cuttings summarized by a flower friend (pre-marriage wedding shop). Experience.

Key point: cut off the hollow part at the bottom of the water spinach stem. Doesn't each section of water spinach have partitions like bamboo? (The fourth step in the picture below) Just cut to the place where the partition is visible, then insert it into the soil, and it will not rot.

Sowing water spinach

Generally speaking, water spinach seeds are not very expensive. Generally, a pack of seeds costs about 3 yuan. The sowing time is around April. Of course, it can be sown until August, and the germination temperature is 20-35°C. It can be germinated before sowing, that is, soaked in warm water at 50-60°C for 30 minutes, then soaked in water for 20 to 24 hours, taken out and washed, then germinated at a temperature of about 25°C. Keep it moist during germination, rinse the seeds once a day with water, and sow the seeds after the seed coat splits.

Daily maintenance: Water spinach likes a high-temperature and high-humidity environment and likes light, so during normal maintenance we can give it plenty of water. Water spinach can be grown in water in the south. If it lacks water, the taste of water spinach is worse, so do not be afraid to water the vegetables.

Harvest: Usually, when the seedlings are about 25 to 35 cm tall, they can be harvested. When picking, leave 2 to 3 nodes at the base and pinch off the young shoots by hand.

[Summary] The above is the potted growing method for water spinach. I hope it can help everyone. Water spinach grows very quickly. Each time we pick it we pick the topmost part, so it can resume growth and continue to be harvested.

Osmanthus is a flower that everyone likes very much. It is a common landscaping tree. Osmanthus fragrance can not only be used as tea, but also for medicinal purposes. Its economic value is very high. So how are osmanthus tree seeds grown?

●Sowing osmanthus tree seeds generally uses the strip method. The specific style is:

A. First, make horizontal or vertical grooves on the seedbed, the width of the groove is 12cm, and the depth of the groove is

B. Sow one germinated seed every 6-8cm in the groove, generally 30,000 seeds can be planted per mu.

C. Place the hilum side facing the side of the seedling to avoid bending the radicle and young stem and affecting seedling growth.

D. After sowing, cover with fine soil. The thickness of the covering soil should not exceed 2 to 3 times the transverse diameter of the seed.

That is, after covering with soil, level the surface to avoid water accumulation, then cover with a thin layer of straw so that the soil cannot be seen, and press the rope tightly to prevent the grass from being blown away by the wind

F. Then spray water thoroughly with a fine watering can until the soil is soaked through. Covering with grass and spraying water can keep the soil moist, avoid soil compaction, and promote seed germination and early emergence.

●Seed germination time and details. Pay special attention to the following points:

First, uncover the grass. When the seeds sprout from the soil, properly uncover the grass on cloudy days or in the evening. The grass should be uncovered carefully and in sections, and part of the covering grass can be left between the seedlings to keep the seedbed moist, reduce water evaporation, and prevent weed growth.

Second, shading. After uncovering the grass, shade should be provided in time so that the light transmittance of the shade shed remains at 40%, and ensure that the cover is put on in the morning and removed in the evening; in sunny places, shade can be stored and kept with reed curtains on rainy days and in mid-September.

Third, loosening the soil. Loosening the soil must be done carefully and in a timely manner, to a depth of 2-3cm. It should be shallow rather than deep to prevent root damage.

Fourth, weeding. Weeding can be combined with loosening the soil, and efforts should be made to achieve it early, remove small weeds, and remove them completely. In addition, weeds in ditches, paths and ridge edges should be cleared to clean the ground and eliminate pests and breeding sites.

Fifth, between seedlings and osmanthus, there are fewer seedlings because osmanthus seedlings have strong resistance to shade and grow slowly.

Sixth, when transplanting seedlings, be careful not to damage the root system of the preserved seedlings. After transplanting, irrigate the seedlings once so that the seedling root system is closely combined with the soil.

Seventh, irrigation and drainage. Osmanthus trees have high water requirements. In the dry seasons of summer and autumn, attention must be paid to drought resistance of seedlings, and the irrigation time is in the morning and evening. Use the method of rapid irrigation and rapid drainage, water evenly, and strengthen drainage in the rainy season to avoid seedling damage.

Eighth, fertilization. One month after the seedlings emerge, they enter the vigorous growth period. At this time, ensure that decomposed dilute fertilizer or nitrogen fertilizer is applied once a month. The concentration is 10kg of fermented fertilizer or 150-200g of urea or 300-400g of thiamine per 100kg of water. As the seedlings grow, the fertilization concentration can be appropriately increased. After fall, stop topdressing to prevent seedling growth and freezing damage. When topdressing, do not let fertilizer adhere to the seedlings to avoid damage.

Ninth, pest control. The most common diseases of osmanthus seedlings are brown spot disease and wilt disease, which cause leaves to turn yellow and fall off, and the roots and root cortex of the seedlings to rot, leading to the death of the whole plant; it is also prone to aphids, so special attention should be paid.

Tenth, transplanting. Osmanthus is generally 1 year old, and the seedling height can reach 20-30cm, and it can be transplanted the following spring. The height of 2-year-old seedlings is about 60 cm, and when the height of 3-year-old seedlings is about 1 meter, they need to be transplanted again. Many osmanthus trees are used as shade trees or street trees. This requirement is relatively high. It usually takes 8 to 10 years of cultivation, with a height of 2 to 3 meters and a base diameter of 8 to 1.
