Pyracantha fortunei planting: 1. The upper pot of pyracantha is usually placed in a round purple sand pot, and the bottom of the pot can be coated with some rotten cake fertilizer, hoof pieces or manure. Generally, potted soil consists of 4 parts humus soil, 5 parts garden soil and 1 part river sand. After planting, water it, put it in the shade for 7 ~ 10 days, and then put it in the sunny place for maintenance. 2. plastic trimming. Pyracantha fortuneana is widely distributed in southern provinces. Ornamental pyracantha can be potted, and old piles can be dug in the wild. After 1 ~ 2 years of green cultivation, we can start modeling. Can be made into straight stems, inclined stems, bent stems, cliffs, hanging branches and so on. Because the old stems of Pyracantha fortuneana are thick and hard, it is difficult to twist, so the shape should be guided by the situation, considering the overall layout and polishing. Pyracantha fortunei has soft and slender branches and good toughness, which is suitable for cliff-type and vertical-branch potted fruit trees. Pyracantha fortuneana mainly bears short fruit branches. After fruit setting, 2 ~ 3 buds should be cut from the long branches to form the fruiting mother branches. Generally, long branches should be sparse. If this part is free, it can also be cut short to make it branch and bear fruit. Pyracantha inflorescences are densely bunched, and each inflorescence has dozens of flowers, so flowers should be sparse. Generally speaking, the ornamental surface should be thinner, the back should be thinner, the flowers should be cut more densely, the flowers should be cut less or not, and the fruit should be thinned again after setting, so that the color of the fruit is bright and the tree shape is beautiful. For the fruits hanging on trees, except for viewing during the Spring Festival, they are generally picked after New Year's Day to avoid consuming nutrients and improve the storage and nutrition level of trees. Different shapes have different maintenance conditions. The drooping potted trees should be placed in a semi-cloudy and semi-sunny environment to make the new branches slender and soft and reach the required length as soon as possible. The potted trees that have been shaped should be placed in a place with sufficient sunshine and long illumination time, so as to control the growth of branches and facilitate flowering and fruit setting. The flowering period should be placed in the leeward and sunny place, which is beneficial to fruit setting. After the fruit is harvested, it should be stored in a sunny place to make the fruit colorful. After the fruit is ripe, it should be moved to the semi-cloudy and semi-sunny place to overwinter in the cold room after autumn, and the room temperature should be kept at about 8℃. Too high temperature and poor dormancy will affect the differentiation, flowering and fruiting of flower buds. In the growing period, light pruning is feasible. If the shoots are too long, they can be picked to promote branching. Usually, the growth of branches should be checked frequently, and methods such as branching, bending, bracing and bending should be adopted to make them meet the modeling requirements. 3. Fertilizer, water and base fertilizer should be applied in winter. Generally, decomposed cake fertilizer or manure can be applied, and each pot is 1 ~ 2kg. In the vigorous growth period, sufficient fertilizer and water should be applied, and decomposed pancake fertilizer 1 time per month, or 0. 1% compound fertilizer, and phosphorus and potassium fertilizer 1 ~ 2 times before flowering, which is beneficial to fruit setting. Usually keep the basin soil moist, and when it is dry, it will be wet. Water should be properly controlled during flowering period to make the pot soil slightly dry, so as to facilitate fruit setting, avoid water accumulation in the pot soil and prevent root rot. Enter indoors in winter (165438+1mid-October) and put it in a sunny place. Because pyracantha is cold-resistant, it is not easy to enter indoors too early, the temperature should not be too high, and the fruit will not fall after the year. In May of the following year, flowers and fruits meet, and white flowers and red fruits set each other off. Pyracantha fortunei is vulnerable to stem borers in cultivation, which leads to the death of branches. Red spiders, cobworms and aphids often occur, so attention should be paid to prevention and control.
