The latest course of rose cultivation techniques and methods

Rose belongs to Rosaceae, Rosaceae deciduous shrubs, branches multi-needle, odd-pinnate compound leaves, leaflets 5-9, oval, the back is densely covered with white villi with edge thorns. Petals Obovate, double to semidouble, purplish red, white, fruiting August-September, oblate.

Soil preparation

Rose is a perennial woody plant with a long production cycle. Cutting seedlings can be harvested for 3-4 years, and grafted seedlings can be harvested for 5 years. In order to obtain the high quality, high yield and high benefit of cut flowers, the soil for planting roses must have good physical and chemical properties during cultivation. It is better to choose muddy loam with low groundwater level and loose ventilation. The soil should be rich in organic matter, and the content should be more than 10%. The pH value of soil is about 6 and 5. Soil improvement should be combined with planting bed arrangement, through deep turning and applying a large amount of organic fertilizer, the soil permeability and water retention and fertilizer can be improved and maintained for a long time, and promote the long-term growth of rose root system. The kinds of organic manure for improving soil can be cow manure, pig manure, sheep manure, chicken manure, bone meal, rotten leaf soil, compost and so on.

The planting border should be smooth according to the width of the border surface 0.9m, the bottom width of the walkway 0.5m and the height of the border 0.5m. After the planting bed is finished, it is necessary to check the pH value and EC value of the soil again, and adjust it with fertilizer, acid and alkali so that the pH value is about 6.5 and the EC value is adjusted to 0.8~1.2mS/cm. If the EC value is less than 08, the EC value can be leached with water. Drip irrigation is pre-installed.

Cultivation mode and planting

The broken branch cultivation method is mostly used in rose production, and the cultivation method is single-row and double-row cultivation, plant spacing 12cm, row spacing 50cm, planting 5000 trees per mu. The cultivation in greenhouse can be planted all the year round, and it can be planted in a straight line when planting to ensure that the seedlings are straight and beneficial to management. The planting depth is slightly deeper than the cutting depth, but the soil should not exceed the main bud of the seedling. The slow seedling period of modern industrial production is short and the survival is fast.

After planting, pour enough root water in time, pay attention to shading and cooling and spray water to the leaves when planting in high temperature weather. Fully ensure that the root soil and topsoil are moist within a week after planting, spray water on the leaves during the day, and properly shade; gradually reduce the amount of foliar watering after 7 days, but keep the topsoil moist, and spray fungicides such as carbendazim or chlorothalonil for a disease control; gradually reduce the amount of soil watering after 15 days, and then timely watering according to the soil dry and wet conditions, keep the soil moist, and begin to use drip irrigation system; enter normal management after 30 days.
