Winter and Spring Fruit Management Techniques

Pour enough frozen water and fertilize before freezing. This fertilizer is extremely beneficial for flowering and fruiting in the second year. 100 kg of organic fertilizer can be applied to each plant, 0.5 kg of organic fertilizer is applied per 0.5 kg of fruit, and 1 to 2 kg of urea per plant is used depending on the size of the tree. Do a good job of whitening the trunk to prevent freezing of the trunk. Use 10% lime water, mix appropriate amount of loess, salt, and vegetable oil, and apply it on the stems of fruit trees in the early winter and early autumn to ease the temperature changes on the stem surface and prevent frost damage and rot. Do a good job of winter trimming. Can be carried out after falling leaves, do not injure the bark, to protect the larger cut rot to be rot and to protect against rot. Do a good job of scraping the old skin in spring. From the end of February to the beginning of April, the germs and pests hidden under the old skin can be eliminated and their wintering base can be reduced. However, the skin scraping should not be excessive, and the old scraping skin scraped should be burned. Do a good job of scraping the apple rot disease. From October to November and from February to March in the following year, it was the peak of two apple rot diseases. It was necessary to check and timely scrape the diseased skin and apply new anti-rot drugs. Do a good job of tree disinfection in early spring. In early March, the whole tree is sprayed 1 to 2 times with 50 to 100 times the amount of Formosa arsenic to destroy the bacteria. In early April, it sprays 3 to 5 Baume degree lime sulfur to kill the wintering spider mites, aphids and pathogens. In the bud stage, spray 0.5 times of Baume degree lime sulfur. Pouring enough germination water to apply base fertilizer. After the soil is thawed, a fertilizer is applied, and urea is used as the main compound with some nitrogen, phosphorus, and potassium multi-element compound fertilizers, and the water is poured. Branches make up fat. During the germination period of spring fruit trees, branches sprayed once or twice with 0.5% urea and 0.3% borax, which resulted in uniform flowering period, flower hypertrophy, increased fruit setting rate, and neat fruits. Can also be sprayed twice in this period 200 to 300 times Huimanfeng, so that budding in advance, improve the fruit setting rate. China Agricultural Network Editor

Integrated Roughness Profilometer

Roughness Profilometer, also known as surface roughness meter, surface smoothness meter, surface roughness tester, roughness measurement meter, roughness tester, and other names. It has the characteristics of high measurement accuracy, wide measurement range, easy operation, portability, and stable operation. It can be widely used for the detection of various metal and non-metal processing surfaces. This instrument is a pocket instrument that integrates sensors and hosts, with handheld characteristics, making it more suitable for use in production sites. The exterior design is sturdy and durable, with significant resistance to electromagnetic interference, in line with current design trends.

The application fields of roughness meters include:

1. Mechanical processing and manufacturing industry, mainly metal processing and manufacturing. Roughness meters were originally developed to detect the surface roughness of machined parts. Especially, stylus type roughness measuring instruments are more suitable for detecting hard metal surfaces. For example, the automotive parts processing and manufacturing industry, the mechanical parts processing and manufacturing industry, and so on. As long as these processing and manufacturing industries involve the surface quality of workpieces, the detection application of roughness meters is essential.

2. In the non-metallic processing and manufacturing industry, with the progress and development of technology, more and more new materials are applied to processing processes, such as ceramics, plastics, polyethylene, etc. Some bearings are now made of special ceramic materials, and pump valves are made of polyethylene materials. These materials have a hard texture, and some applications can replace metal materials to make workpieces. During production and processing, their surface roughness also needs to be tested.

3. With the continuous strengthening and improvement of the technology and functions of roughness meters, as well as their in-depth promotion and application, more and more industries have been found to require roughness detection. In addition to mechanical processing and manufacturing, roughness evaluation is also required in the production and processing of power, communication, electronics, such as couplings on switches, integrated circuit semiconductors, and even stationery, tableware, and other products used in people's daily lives The surface roughness of human teeth needs to be tested.
