Introduction to rose culture methods:
Rose breeding and cultivation is easy. Breeding is usually carried out by sowing, ramets and cuttings. Sowing is required in the fall and will be planted for sand treatment. Sand storage method: Mix the sand with a small amount of soil, pour it with water, hold it in a hand, and granulate it into a grain. The seeds are then washed and mixed into the sand. In the sunny or semi-caston, digging 60 cm wide and 80 cm deep, the east-west gully, the sand mixed with seeds is buried in it, leaving pores. Excavated at the beginning of the spring of the next year, the seeds with the broken grain are the best. The ramets can be propagated in spring and autumn, and autumn is good.
The seedlings of 1~2 years old are separated from the old plants by the roots, and the wounds can be disinfected better and become more viable. Cuttings are mostly carried out from July to August. Choose two-year-old strong and full-fledged branches, cut 15~20 cm long knots for cuttings. Each cutting head needs to have at least three leaf buds, and the lower part is cut into horseshoe-slanted shape with the upper part parallel. Potted inserts and cuttings can be used. After insertion, it should be shaded, sun-protected, and often sprinkled with water to maintain a certain humidity and temperature. It takes about a month to root and become a new strain, which can be transplanted after one year.
Roses are hi-light, hi-yang, cold-tolerant and drought-free. As long as there is no drought, it can grow without watering (referring to the ground planting). The requirements for the soil are not strict, generally the fertile soil can grow vigorously, the leaves are leafy and the flowers are good. Fertilization should be carried out in summer, and it should be applied every 15~20 days. After fertilization, it should be watered in time to prevent burning. It should be trimmed in the fall to prevent the growth of the flowering and plant type. Roses are more locusts, pay attention to prevention.
The cultivation of roses is not strict with the soil, but it is most suitable for medium or micro-soil, and slightly acidic soil. Therefore, roses should be planted in fertile loam in the fields of ventilated sun and watering, good drainage conditions, and ground. Roses are low-lying and easy to smash. When they encounter cockroaches, the lower leaves turn yellow and even the whole plant dies. The flower bud and germination of the rose requires an average temperature of 7 degrees or more. From the initial stage of germination to the flowering stage, the temperature needs to be 365 degrees, which is generally determined by the temperature. In the rose period, the hot air and the soil are most dry, and the fields with water conservancy conditions can be irrigated. In the process of production and development, the rose has stopped growing for two times (generally called summer sleep in June-July; hibernation in November-December). At this time, no branches are produced and the branches are not elongated. The summer sleep period is the best pruning period for the flowering seedlings. During the hibernation period, it can be combined with the base fertilizer and the wintering water, which lays a foundation for the stable and high yield of the flower buds in the coming year.
General Purpose Powder-Actuated System is used for building fastening, which have three parts: Actuated tools, Cartridges and fasteners. When Actuated Tool strikes cartridge and cartridge will explode in the inner of tools and produce a lot of high temperature and high pressure gas. The gas will push the piston and the piston will push the fasteners into the basement. Or the gas will push the fasteners directly into the basement. Like this, we can fix a lot of things into concrete and steel basement tightly.
The fundamental is as the following:
The Actuated tools are classified for direct tools and undirect tools, we can also called high velocity and Low velocity tool, the fundamental is as the following:
High velocity tool:
Low velocity tool:
Based on different purpose, Cartridges are classified for different calibers and dimensions. The usual caliber and dimension is as the following:
.27calX11mm(S1)
.22calx15mm(S5)
.22calx16mm(S52)
.27calx18mm(S3)
.25calX16mm(S43)
At the same time, each caliber cartridge is classified for different specification based on the quantity of inner powder, which is marked by different color. when the color is more darker, the power level is stronger. otherwise, the power lever is lighter.
The fasteners are classified for different categories. Each different category is classified for different specification based on different length and diameter. At the same time, it is can also be re-designed based on special use.
The packages are as the following:
1. Tools: one tool/ plastic box/carton or five boxes/carton
2.Cartridge: 100pcs/paper or plastic box, 100boxes/carton.
3. Fasteners: 100pcs/paper box, XX boxes/carton.
For shipment, all cartons will packed by pallet.
