Planting techniques of red roses
As follows: Red roses can be planted singly or interplanted, suitable for barren hills and slopes, and scattered fields. If there is no special land, they can be interplanted with orchards or cash crops with short growth period. After loosening the whole field, only one field should be dug. The size of the cave is 8 inches square, and the cave surface is off the ground 1 inch. Row spacing per plant 1 m is enough. Agree to plant 120 plants per mu. Generally in late April (between Grain Rain and Changchun), seeds with full seeds and no pests should be directly sown. Before sowing, put half a handful of calcium superphosphate and appropriate amount of soil in each hole. Finally, there were 1 seedling per hole, and the seedlings propagated well. Some people say that the cuttings of roses are lifeless, but in fact they can survive, so cuttings can also be used to breed roses. "Reading Mirror" noticed that every time a new rose was painted, its roots would wither easily, so it was necessary to quickly transplant the twigs next to the roots, and then its roots would remain the same, so it was commonly called "leaving the mother grass". In most places, the method of dividing plants is used for propagation, generally during the dormant period (from defoliation to germination), both in spring and autumn. The method is to dig out the whole plant first, mix the plants scattered in the soil together, then cut off a branch, remove the old roots and plant it alone, or keep the mother plant still, cut off the new plant and plant it alone, which is very simple.
Red roses should be fertilized immediately after thinning. I applied water fertilizer, plant ash and other miscellaneous soil fertilizers, and dug ditches to cover them when fertilizing in sunny days. If it is better to apply chemical fertilizer in rainy days, you can spray 5 kg of ammonium bicarbonate and water per mu. At the same time, intertillage weeding must be completed before the heat, and then weeds should be pulled out. Before budding, flowers should be sprayed with 10 kg urea or compound fertilizer per mu in time after rain. Roses are naturally fat, and if they are not fat enough, they won't bloom much. Overwintering fertilizer and petal fertilizer are essential, and the principle of light application should be implemented on weekdays to maintain vigorous growth.
Red roses have strong disease resistance and few diseases and insect pests occur. Once it happens, each mu can be sprayed with 1 dichlorvos or thiophanate-methyl mixed with water. For example, pests can be sprayed with appropriate amount of pesticides, and diseases can be sprayed with appropriate amount of amobam or neomycin, and more chemical fertilizers can be applied. Special attention should be paid to the prevention and control of underground pests, which can be trapped and killed. Put a teaspoon half a foot in each hole, make it quickly before sowing and treat it three times. After flowering, the branches of pests and diseases and the old branches should be pruned. The soil should be cultivated to prevent freezing in winter.
During the flowering period, roses usually bloom at dawn every day, and the standard is that the buds are just put into rings every day. If the flower is closed and the flower heart is yellow, you can pick it. If the flower heart turns red, the quality will drop. Therefore, the time to pick flowers every day must be before the dew is dry in the morning. Before dawn, the petals are exposed. The amount used for refining essence is high, and the oil content of roses picked with dew is high. If the temperature is low and the flowers bloom late, the picking time can be postponed appropriately. Picking roses is a hard and interesting job. Flower farmers invade the sea of flowers at dawn every day and soak in the fragrance of roses, just like experiencing a "fragrant bath."
Planting red roses can harvest its flowers and fruits and sell them in the sun, so it must be harvested in sunny days. Generally, it takes about seven months from sowing to collecting flowers and fruits. The standard of harvesting is that when the leaves turn yellow and the seeds turn black, you should hold the stem tip with one hand and gently pick it with the other. After harvesting, it needs to be dried for 2-3 days before processing. When processing, hold a flower and fruit in a circle with the index finger and thumb of the right hand, and hold the pedicel with the left hand and lift it out hard to separate the seed from the peel. Fresh red rose pulp is hard and brittle, which is not easy to process, but it is not easy to process if it is over-dried, so we should also pay attention to moderation when drying.
