Rose cultivation management points

1. Planting is mainly planted and there are also a few potted plants. In the Yellow River basin and its areas south of the area can be planted, exposed winter. In the cold northern regions should be potted, indoor winter, or digging trenches buried winter. It can be planted after falling leaves in autumn and before sprouting in spring. It should be planted in a place with high topography, sunny reach, and no standing water, and the depth should be 15 cm from the ground. Potted plants were cultured with rot-leaf, garden soil, and river sand. Wells were added with appropriate decomposed manure or cake fertilizers and compound fertilizers. After the plant was poured, it was permeable for 1 time and the seedlings were placed in the shade and cultivated for several days before being moved to sunlight.

2. The light and temperature of sunlight can promote good growth. Regardless of the land planting, potted plants should be placed in sunny places, to accept more than 4 hours of direct sunlight every day. Can not be placed long-term in places with insufficient indoor light. Enter the room in winter and put it in the sunny area. Suitable growth temperature 12-28 °C, can withstand -20 °C low temperature. It is safe for wintering in the Zhengzhou area.

3. Before watering and fertilizing, appropriate amount of organic fertilizer is applied in the tree hole before planting. To plant roses, the requirements for water and fertilizer are not strict. Generally, there are three fertilizers. First, before flowering, it is necessary to apply furrows before the buds of spring buds. It is better to use rotten manure and rot leaves. The second is after the flowering of the flower, thanks to the spent cake fertilizer slag, to supplement the flowering consumption of nutrients. The third is to enter the winter fertilizer, cast manure after falling leaves to ensure that the rose safely winter. Potted roses can be applied to the cow for a long period of time and can be applied for 10-15 days. Roses are tolerant to drought, and usually they are usually planted without watering, and are poured once every 20 to 30 days during summer or spring drought. The pots were poured 2 times a day and poured 1 time a day during the summer or spring drought.

4. Plastic pruning generally does not require pruning, and the old strains can be repaired to have dense branches, stem branches, and pests and branches. The rose blossoms, picks up with the opening and losing, picks it again, otherwise it only opens 1 flower.

5. Flowering is generally controlled by the natural flowering period.

Leveling the land Choose a thick soil, loose structure, well-drained plots to build a rose garden, dig pits with a spacing of 50 cm, spacing 150-200 cm, and a pit depth of 50 cm, applying 10 kg of farmyard manure or bio-organic fertilizer per pit.

Choose a good seedling to choose robust rose seedlings, sprouting seedlings should have 2-3 branches; grafted seedlings require station root system developed, stem diameter 3-4 mm, plant height 30 cm, to be with the plant, shipped to the field Seedlings should be packed with pulp.

In order to save land, planting 1500-2000 trees per acre can be planted in accordance with the requirements of reasonable close planting. About 2 000 rose seedlings per acre are needed. In the second year, seedlings can be transplanted or sold, and the spring planting is before the rose sprouts. In the early spring, autumn is planted from October to December, and summer planting takes place on rainy days in the rainy season.

Scientific management of cultivating and weeding, due to small seedlings, weeds are very easy to grow, we must do a good job of sorghum in time, so as not to hurt the seedlings and no grass. Keep the soil loose. Fertilization uses organic manure as the main fertilizer, usually four times in the year. The first time before and after the Ching Ming Festival, the water is poured into the livestock manure water, which is called germinating fertilizer and is watered in time. The second time in late April, the buds or the second time before the flower is collected, the second time the livestock manure is applied. Water promotes many and full buds; in May organic bio-fertilizers are applied and winter fertilizers are applied at the end of autumn and winter to ensure safe wintering of seedlings. After the flowering in June and the dormant period in winter, old branches, diseased shoots and weak branches were cut off and new branches were planted. Pay attention to the prevention and control of pests and diseases during all stages of field management.

Disease and Insect Pest Control (1) Aphid and Spodoptera exigua: Harmful plants and leaves damaged, can be used 40% omethoate 2000 times spray or methamidophos water spray. (2) Scarab, small tiger: Hazard to the roots of plants, available for bait trapping. (3) rust disease: There are leaves and dorsal leaves.
