What good method is there in breeding? What matters should we pay attention to when breeding auspicious fruit? Please read down with me with your questions!
Cultivation method of auspicious fruit (basic knowledge): the best propagation time: the best propagation time of auspicious fruit is from late March to early April, and the planting time can be in late autumn or early spring.
The best growing soil: 1 / 2 legume straw composting soil 1 / 4 garden soil 1 / 4 sandy soil, in which 25% NPK compound fertilizer is added properly.
Growth humidity requirements: when the plant is flowering and fruiting, the demand for water is very large, usually keep the soil moist.
The best growth temperature: the best growth temperature of auspicious fruit is 18 ~ 27 ℃.
Best growth light: it's best to put it under the sun during the day, so that the auspicious fruit grows well.
In order to give full play to the effect of fertilizer and meet the needs of the growth of Jixiang fruit tree pile, the new pile is generally not fertilized from March to April, 0.2% urea solution is applied to the basin soil and leaves every 10 days from May to June, rapeseed cake water is applied every 10 days from July to September, and chicken manure diluted by 10% is applied every 15 days from October to December Fertilization was stopped from January to February of the next year.
Key points of watering: for the Jixiang fruit tree pile in the first pot, after the new buds grow 5cm ~ 6cm, it can be watered once a day. Pay attention to the pot soil not to be too wet, so as not to affect the normal growth of new roots. When the new buds grow 8 cm ~ 10 cm, the new roots have basically formed, which can be watered according to the growth condition of the plant.
Pruning tips: the germination rate of Pyracantha fortuneana is high, the branches and leaves are luxuriant, the trees are easy to be dense, and the tree shape is chaotic. It needs to be pruned many times in a year. Potted Pyracantha fortuneana can be made into a single stem round head shape, with a stem height of about 30 cm. It can be pruned at any time during the growth period, and the branches can be sparse for many times. The excessive branches, over dense branches and dead branches should be cut off in time to keep the tree beautiful, ventilated and transparent. When pruning in winter, the dense branches can be thinned, and some branches can be cut short, which can not only promote the development of branches, but also control the plant height and maintain the beautiful tree shape.
Basin soil replacement: auspicious fruit bonsai fruit every year, the nutrient consumption is very fast, generally the best time to change the basin in late February to Qingming. Before the new buds germinate, the leaves and fruits are removed, and the nutrient soil with phosphorus and potassium fertilizer is used to change the pots.
Propagation key points: seed sowing or branch cutting propagation seedlings, sowing in late March to early April, strengthen fertilizer and water management after emergence, and cultivate strong seedlings that can be planted in pots. Hardwood cutting was carried out in March. Softwood cutting should be carried out in June. After cutting, shade should be provided above the nursery. After new roots grow, shade objects should be removed. Water management should be strengthened for cutting seedlings to cultivate strong seedlings.
Disease and insect control: Jixiang fruit is easy to get powdery mildew, damaging leaves, twigs, flowers and fruits. This is due to insufficient light, poor ventilation and long shading time. It can be controlled by spraying Bordeaux mixture, stone sulfur mixture or carbendazim. There are two kinds of pests harmful to the growth of auspicious fruit: one is the stinging and sucking scale insect, which can make the growth of tree stump decline, or even the whole plant die. The scale insect has a wax layer on its surface, so it is difficult for drugs to enter the insect body. Prevention and control methods: to often observe, such as the discovery of scale insects to immediately use wire, stick or knife to get rid of scale insects. 1% oil floating agent can be used to spray the tree, and 1% carbofuran can be buried in the basin soil to kill the insect through internal absorption. Second, aphids are easy to occur in spring and autumn. Aphids harm tree stumps, which can distort new shoots and young leaves, and the feces excreted by aphids fall on the leaves and fruits to form small black spots, affecting the ornamental effect of auspicious fruit bonsai. All aphids could be killed by spraying 40% Omethoate 1000 times or 80% dichlorvos 800-1000 times twice.
Auspicious fruit pot culture auspicious fruit experience: 1, to cultivate good auspicious fruit, to understand its habits, spring is one of the most vigorous seasons of its growth cycle, late spring, early summer and even autumn, mainly to prune and shoot. So in spring, we should take good care of it, water and fertilize in time, observe the flowers and leaves in order to prevent all kinds of diseases and insect pests. During the day, we must put it in the place where the sun shines. Autumn is another growth peak. It's better to take off the top advantage when cutting shoots. Avoid the nutrient consumption of autumn shoots, which is harmful to overwintering and fruit setting. 2. Overwintering management. In order to avoid severe cold damage, potted Pyracantha fortuneana can be moved to the place where the wind is away from the sun or to the room for overwintering in winter. Check the basin soil frequently during overwintering. If the basin soil is too dry or before the cold current comes, it should be watered once to prevent freezing.
