Potted Phyllostachys pubescens in northern China
Purple bamboo can be potted.
1. Select bamboo. Select Phyllostachys pubescens with dense bamboo joints and short branches and leaves, leave 1 ~ 2 leaves and cut them off. Two-year-old bamboo with soil on its roots and strong bamboo whip should be planted in a pot.
2. Choose a basin. You can choose a medium-deep purple sand pottery basin or glazed tile pottery basin, or you can use a clay basin, a tile basin, a plain burning basin or a plastic basin. The shape of the basin can be round, square or polygon, lotus basin, rectangular basin or oval basin. Should choose pale yellow, light gray or plain pot, generally do not use purple or green pot.
3. Choose the soil. Zizhu likes loose and fertile sandy soil, which is rich in humus and has good drainage and permeability. 5 parts of loose mountain mud, pastoral soil, pond mud and humus soil can be used as culture soil, 3 parts of river sand, coal cinder, edible fungus leftovers and chaff ash, 2 parts of high-quality decomposed farm manure, livestock manure and compost, and a small amount of calcium superphosphate can be mixed and stirred.
Step 4 serve food. Phyllostachys pubescens should be transplanted in pots from February to early March in spring or from September to 65438+ 10 in autumn. Stewed bone pieces, cake crumbs, bone meal, etc. As a base fertilizer, it is applied to the basin bottom. You can plant a single plant, or you can plant a number of purple bamboos with different heights together in a pot, and the height and density should be changed.
5. Environment. Zizhu likes a warm, humid and sunny environment, and should be maintained in a sunny place during the growing season. In summer and early autumn, shade 80% ~ 90% from 9: 00 a.m. to 5 ~ 6: 00 p.m. on sunny days to prevent strong sunlight, or move it to the southeast balcony or windowsill, or move it to a green shed or a shady place for maintenance. Overwintering in the leeward and sunny places in winter, it is best to bury the pot underground for overwintering; Northern areas should be moved indoors or in greenhouses for the winter.
Water it. When growing, always water and spray foliar water, keep the soil moist and not waterlogged, avoid water accumulation in the basin, water thoroughly, and avoid watering half. In winter and after bamboo shoots are exposed, water should be reduced appropriately to keep the basin soil dry and wet.
7. Fertilize. In the growing season, liquid fertilizer should be applied 2 ~ 3 times a month with water. 0. 1% ~ 0.3% potassium dihydrogen phosphate aqueous solution can be added to the decomposed cake fertilizer water for irrigation. The temperature is too high in summer and no fertilizer is applied in winter.
9. Trim. After bamboo shoots are unearthed, according to the modeling needs, bamboo shoots can be bent in combination with water control, sharpened and topped at an appropriate height, and branches and leaves can be trimmed in time to increase the ornamental effect.
10. Pest control.
At ordinary times, we should strengthen the cultivation management, pay attention to the ventilation and light transmission of the environment, and pay attention to the prevention of witches' broom, bamboo shoot blight, stem rot, bamboo moth, bamboo moth, bamboo locust and other pests and diseases.
Garden zizhu planting method
First of all, the choice of pot soil, potted purple bamboo planted at home is better to feed, as long as the temperature is enough and the sunshine is enough, the selected soil should be loose. You can choose to plant purple bamboo in plastic pots, and you can usually water it with rice washing water.
Second, water and fertilizer management. Zizhu likes warm and humid places. According to the weather changes during the growing period, the basin bottom should be watered every 2-5 days, not too much to prevent the roots from rotting. After bamboo survives, apply fertilizer appropriately to achieve' thin fertilizer and diligent application'. Temperature and illumination: Zizhu is most suitable for 18℃ to 25℃, and it is not suitable for exposure in summer. It's best to put it in a sunny place, otherwise it will lose its luster. When the temperature drops below 5℃, it should be kept indoors for the winter.
3. Then, update communication. If it is found that the height of Phyllostachys pubescens is not balanced with the size of the pot after planting for a long time, it can be cut short from the pot soil 10cm ~ 15cm in May and June, and new branches will grow on the lower part after subtraction. The cut stems are not useless, and they can continue to reproduce. Plant the cut purple bamboo directly into the soil as long as it takes root.
4. Then, don't put it in an excessively dry place. The first time the basin water must be poured through the bottom, and then the basin bottom must be kept moist, but not too much, otherwise the roots of Zizhu will rot, greatly reducing its ornamental value.
Then, from the time he was put into the pot until he survived, he should always spray water like the surface of a leaf. If he finds the leaves curly, he should water them in time. The organic fertilizer of potted Phyllostachys edulis should be applied "thinly and diligently" after survival.
Finally, potted Phyllostachys edulis should also pay attention to pests and spray 80% dichlorvos emulsion. If you pay more attention to ventilation and light transmission, you can effectively prevent the harm of pests and diseases. At ordinary times, we should strengthen management and trim bad branches in time.
