Chinese rose pruning method

Pruning time: warm areas in late February, colder northern areas, trimming work to be carried out in March to April. Trim part: Trimming is generally about 1/3 of the height of the crop. The first step is to remove weak branches, diseased branches and dead branches. Last year, the newest plant was born with the most vigorous growth. The main branch was left with 2 to 3 strips of up to 5 pieces. According to the original growth of the plants, they were generally cut from the ground by about 50 centimeters. . The so-called "vigorous buds" are along unsprouted, plump, uplifted buds. In order to prevent the shoots from growing into dense shoots, strong shoots should be left on the outside of the plant. In addition, pruning should be done on the full part of the branches. When you trim with scissors, the sound of “sudden” is the plump part. If you feel that the incision is soft, cut it down to a hard place. Aging parts of the plant branches are rough and prominently bulging. There are no studs at all, so they must be cut off. The middle part of the main branch of 2~3 years is the new shoot multiple site, so only 10~20 cm can be left when pruning. In general, if you want to spend more on flowering, cut it weakly. If you want to spend a good period of flowering, do not ask for more, then make a strong cut. In addition, plants that are not growing well should be determined to cut them hard because the roots of the plants are stunted. If the crowns are too large, nutrient supply may be insufficient. It is best to do a high-concentration disinfection at the same time as pruning, which has a significant effect on preventing pests and diseases. After pruning conservation work: In order to tilt the trimmed branches outwards, they can be fixed with pillars (sticks, etc.) to make the tree shape balanced and beautiful, and avoid the branches and leaves rubbing each other when the wind blows. The shoots from the lower branches of the inclined branches are more robust and the flowers are luxuriant. Care should be taken to protect them. After the convulsion, the insects wake up from hibernation and start their activities. At this time, 10 ml of pupa pine (insecticide) and 20 g of wet sulfur powder for powdery mildew are dissolved in 10 liters of water and fully dissolved. Spray the plants with concentrated solution. Because at this time there is no long leaf in the Chinese rose season, there is no need to worry about phytotoxicity. About 20 days after pruning, the buds begin to sprout, and the weak buds are often eliminated in the process of sprouting. In order to make the flowers bloom well, the buds should be left according to the thickness of the main branch, leaving 3 to 4 buds for the coarse branches. Leave 1-2 buds on the branches of pencil, and remove all the rest. In areas where the weather is cold, budding is delayed and de-emergence may be postponed. If basal fertiliser has been applied in December, do not top-dressing in the early spring. Sprinkle appropriate amount of quantified fertilizer around the roots for germination. After the buds have been drawn out, if the ground surface is dry on a sunny day so as not to freeze the ground surface, water can be poured in the morning or at noon.

Gantry Type Video Measuring Machine

The gantry-type Video Measuring Machine can efficiently detect the contours, surface shapes, dimensions, angles, and positions of various workpieces. It is mainly used to measure the size and angle of parts and components that are difficult or impossible to measure with a caliper and angle ruler but play an important role in assembly. It can also be used to take pictures of some parts and components to analyze the causes of defects, especially for PCB boards, films, protective films, optical glass, electronics, large sheet metal parts, connectors, precision mechanical parts, electronic components, semiconductor components, and other industries, It can achieve rapid and accurate detection in large quantities.

advantage:

1. Adopting a high-power industrial high-definition color CCD and a continuous automatic zoom depth lens with fixed frame position, the zoom rate does not require calibration, greatly improving work efficiency and measurement accuracy.

2. Images can be output to electronic computer software for surveying and mapping engineering storage. It can be used for photography, copying, and storage.

3. It can inspect the specifications of buried holes, pipe trenches, etc. on the upper surface of the tested object block. The image and color tone on the surface of the product workpiece can be clearly seen.
