1, daily maintenance of original stone flower planting
The key to planting raw stone flowers is to pay special attention to water supply, temperature and light. It is absolutely necessary to wet the soil during the growing period, and it should be kept continuously, with dry-wet intervals and dry-wet alternation. The capillary roots of the middle ball and the ball are dry, and the degree of wrinkles on the ball or the situation that water often flows out from the bottom of the basin should be avoided. The quantity and frequency of water supply should be reduced, such as small balls.
Dormancy period of the original stone flower: the small ball and the middle ball are often watered slightly, which can even slow down the shrinkage phenomenon. When the ball is big, it is necessary to completely cut off the water and let it sleep completely!
The dormant original stone flower gradually loses its luster, and soon the ball will become shriveled and shriveled. At this time, it is necessary to strictly control watering, often use sprayers after sunset in hot summer, or reduce the temperature in the cultivation room to slow down the shrinkage. It depends on the concern of the cultivator!
Try to be careful in the irrigation of raw stone flowers. When peeling, the new ball unfolds from the old body, and there will be some cracks. On the contrary, the growth of the old body and the new ball is shrinking, forming a new laceration. When the small mouth is invaded by water, it will accelerate the atrophy of the old body and the small ball will appear in advance, which is not good for the growing small ball. During peeling (1~2 weeks), water will be cut off, the nutrient supply of roots will stop, and new bulbs will absorb nutrients from the old ones and grow.
2. Culture medium for growing rough stone flowers
As far as the cultural soil of raw stone flowers is concerned, there are various interesting sayings. In fact, among many kinds of succulents, it is not common for raw stone flowers to have low requirements for culture soil. They are usually cultivated and viewed in small pots. According to common sense, we use soil containing a certain amount of fertilizer, and there is absolutely no need to give raw stone flowers a lot of compost or other fertilizers.
The simplest is 8 parts of river sand and 2 parts of high-quality compost soil containing fertilizer. Using spherical soil under the basin can achieve good drainage, and raw stone flowers don't have to worry about rotten roots. The lower part of the sphere is her perishable place. Most suitable for clay soil, the size is between the size of beans and the size of fingers. Cooling in summer is the main way, such as changing some media, putting white stones on the surface, double pots and so on. )
The main purpose of turning over the pot (transplanting) of the original stone flower is to change the soil and provide enough nutrients for potted plants. Because of the limitation of soil, she needs to grow smoothly and turn over the pot for use. Also, with the continuous watering of the basin soil, the drainage condition is also deteriorating. Generally speaking, the fertility of the soil used begins to be scarce after one year. Plants need bigger flowerpots when they grow up.
The best time to transplant the original stone flower is when dormancy ends and growth begins. In fact, if a large number of plants or seedlings cannot be transplanted in this optimal period, it is better to transplant them at any time during the growing period. It can also achieve a full effect. In any case, it is necessary to transplant once a year.
Plants removed from pots by changing pots, dead plants in dormancy and excessively long roots should be removed. For them, new roots will be born soon. If root lice were found at that time, pesticide powder should be used to repel insects when planting.
3. Planting and breeding of original stone flowers
The propagation of the original stone flower is generally seedling raising, branching, cutting and sowing. It is becoming more and more difficult to introduce high-purity seeds from abroad, so it is very important to collect seeds by yourself. Stone flowers usually cannot pollinate themselves, nor can they pollinate themselves. Seed collection must have more than 2 living bodies. The key point is to choose plants with high purity as parents for seed collection. The purity of parents can be judged directly from the seedlings. The most important thing is to choose varieties according to their shape, color and appearance.
Parents should manage flowers at the same time in the same environment and rely on artificial media to bear fruit. If there are only two single-headed varieties, sometimes it is impossible to pollinate artificially without flowering at the same time. If possible, it is best to have 3-4 or more varieties of the same variety. After several years, the parents become group plants, each ball blooms several times, the whole plant has a long flowering period and many pollination opportunities. Two such group varieties are enough. It is forbidden to cross with other varieties of raw stone flowers. In addition to special research purposes, as growers, we should remember the value of pure varieties. Therefore, if the intended parents miss the flowering period, the pens used for pollination should be reused in the next year, which is a responsible cultivation attitude towards gardening.
The flowers of the original stone flower will bloom for about a week in sunny days in autumn. Some flowers bloom for more than a week, and a few days after flowering, the pistil is suitable for pollination when it is star-shaped. Collect pollen from other plants with a soft brush and coat it on the stigma of pistil. The tip of pistil is thin and soft, so be careful when pollinating. After pollination, the ovary becomes larger and larger, and it is fully mature after 6-7 months. Fully mature seeds need another 5-6 months or more after ripening period to be harvested with pods. If you sow before the ripening period, the germination rate is extremely low. Some can't germinate. On the contrary, seeds collected and properly preserved for many years have a good germination rate. It is best to plant in autumn or spring. Autumn is September-165438+1October, and March-April is suitable. Moderate heat preservation in winter is also a season that can be used. Seeds are sown on the washed river sand and kept moist. It takes 5-6 days to germinate, and all seeds need one month to germinate. From time to time, guys who germinate late after 2-3 months:) Precious varieties need long-term careful management.
The soil used for seedling cultivation is ordinary sand without fertilizer. In order to promote the growth of germinated seedlings, other soil containing nutrients will be used for transplanting. At this time, the soil should be used according to the general standard, and there should be 1 ~ 2 cm sand grains on it. The seedlings are small and soft, so be careful when transplanting for the first time. We are all experts in using chopsticks. Let's use this skill flexibly!
It takes 3-4 years from sowing (seedling) to flowering, and it is very common to change two flowers in turn one year later. It will take several years for 5~6 plants to cluster, and large-scale clustered plants are very precious. The greater the ornamental value, the higher it is. A few valuable varieties, weak characteristics, etc. It is safer to plant by dividing plants, and the work of dividing plants is simple. Cut it near the roots with a sharp knife. After a few days in the shade, the incision is dry, and the root can be moved after being inserted into river sand 1~2 weeks. General management will do. (ramets are most suitable at the end of dormancy and before growth begins. )
