Ornamental jujube pot maintenance points
2021-02-24 15:21:21
Jujube is a ramylaceae, deciduous fruit tree of the Chinese genus, native to China. Jujube adaptability, resistance to thin, salt and alkali resistant, easy to manage. Potted jujube products are better for early fruiting, fruiting, branching, and plant shape, such as Long jujube, winter jujube, snow jujube, gourd jujube, teapot jujube, etc., as well as the Wuli River Farm Fruit Research Institute in Sihong County, Jiangsu Province. The cultivated 'potted jujube 1'. Here to talk about ornamental potted plant technology:
1. Nutrition soil configuration and container selection.
4 parts of garden soil, 4 parts of decomposed organic fertilizer, and 2 parts of sandy soil were mixed and the potassium permanganate solution was sprayed. The plastic film was used to cover the nutrient soil, and the plastic film was removed after one week. Pots and pots of purple pots are preferred for the containers. New pots must be soaked in water for three days before use to prevent pots from collecting water and damaging the roots. The old flowerpot must be brushed clean, and it can be scalded with boiling water to achieve the purpose of disinfection.
2. Seedling selection and upper pots.
One-year-old grafted seedlings were selected to require superior jujube seedlings with a seedling height of 50 cm or more and a fresh, thick, well-developed root system. Before the basin, cover the drainage holes with tiles, and then fill the pelvic floor with a large particle of vermiculite about 3 cm thick. As a drainage air permeable layer, remove excess fibrous roots, roots, and roots of jujube seedlings and put them on The center of the basin is filled with nutritious soil, poured with water and covered with a thin film.
3. Water and fertilizer management.
As long as the water in pots and soils should be watered in time, the watering must be thorough, and the phenomenon of “wet and dry†cannot occur. In the flowering period, at noon often with water spray to maintain humidity, there is the effect of flower protection and fruit preservation. During the month before flowering and in the young fruit period, the soil in the pot should be kept moist. Top dressing has a large demand for nutrients. Saplings were planted until the end of May, and 0.1% to 0.2% potassium dihydrogen phosphate was used as the main ingredient. From June onwards, the application of 0.5% to 1% potassium dihydrogen phosphate aqueous solution, flowering period and fruit expansion period, should be applied once every 10 days. At the same time, it is necessary to spray once every two weeks, such as 0.1% urea + 0.2% potassium dihydrogen phosphate + 0.2% magnesium potassium fertilizer or iron-zinc fertilizer mixture. Basal fertilizer is applied in mid-September in the fall. The method is to remove 10 cm deep soil from the pot, then fill in the decomposed organic fertilizer or cake fertilizer, and pour enough water.
4. Prune trim.
Potted jujube tree is very happy, pay attention to pruning, do not shade each other. When the collaterals were extracted, three or four lateral buds were selected to remain strong and evenly distributed, and all the others were cut off. Properly cut dense branches, leggy branches and slender branches to facilitate ventilation and reduce the occurrence of diseases. When entering the flowering stage, the top of the new shoots should be cut off by hand to promote nutrient supply.
5. Keep flowers and fruit and thinning fruit.
In order to increase the fruit setting rate, the spray should be sprayed with 10 to 15 ppm gibberellin (90%) from 5 to 7 days after the flowering period in early June, and sprayed every 5 days for a total of 2 sprays. At the same time, spray borax 5,000 times to promote fertility and strong, spray once every half a month, even spray several times, but can not be mixed with other pesticides spray at the same time, in order to avoid phytotoxicity. In the hard-core period, 10 mg/l naphthalene acetic acid can be sprayed to prevent flowering and fruit drop. Weed out excessive flowers and young fruit, reducing the consumption of nutrients, and ensuring that there are sufficient flowers and fruit left by the supply of nutrients. The first thinning of fruit can be performed after the flowers have been identified, and each inflorescence is left with 1 to 2 fruit. The second thinning of fruit was carried out one month after flowering (the fruit diameter ranged from 1 cm to 1.5 cm). The thinning fruit was the fixed fruit. Generally, one fruit per 2 to 4 leaves was appropriate, and the strong branch had more fruits. Weak branches, leaving fruit, remove chlorosis, pest fruit, malformation, and stay small.
6. Down pot change soil.
Potted jujube grows from 2 to 3 years later, the root system becomes larger, and the basin soil nutrients gradually lack. At this time, nutrient soil and large pots should be replaced. Before spring, April, five days before the pot, the basin soil should be poured with enough water, and the pots prepared for the change should be soaked with water, and the periphery of the soil group should be rooted 3 cm with a sharp blade. To 5 cm thick, cut the soil into the pot, use the prepared nutrient soil to fill the gap, and water can be poured.
7. Pest control.
The pests that injure the jujube tree include green-lipped stinkbugs, juvenile cockroaches, food buds like weevil beetles, beetles, red spiders, and leafhoppers. The diseases include anthrax, ringworm, date rust, and fruit shrinkage. Pest control, from mid-April to mid-May, choose 30% acephate 600 times to 800 times, or 2.5% enemy kill or destroy 3000 times the sweep, alternating spraying 3 times. From the end of May to the beginning of June, it was chosen to spray 1.8% of schizophylline or 3000 mg of scorpion. In mid-June, spray 20% broom net 4000 times liquid and so on. At flowering time, chafers and green-lipped animals can be killed by hand and generally do not spray. If they occur in large numbers, 2.5% trichlorfon powder can be placed in the pot. Disease prevention and control, from the middle of July to the end of August, the fruit growth period, spraying once every 10 days to 15 days, spray a total of 3 to 4 times. The agent is 1000 times of 50% carbendazim, 70% thiophanate-methyl, 75% chlorothalonil, and the like.
