Temperature grapes are open-cut cuttings that have different temperature requirements during each period of growth. When the average temperature in early spring reaches 10 °C, the grapes begin to sprout. As the temperature increases, the new shoots will accelerate and grow. The temperature suitable for shoot growth and flower bud differentiation is 25 °C ~ 38 °C. When the temperature reaches about 25 °C, the grapes can take a lot of roots. Therefore, it is necessary to provide suitable temperature for the growth of the grapes to ensure that the grape roots survive at the same time. Moisture water plays an important role in the life activities of grapes. The nutrients are dissolved in water and transported to various organs. If the soil is too dry, the roots are hard to absorb water and nutrients from the soil, and photosynthesis is weakened. However, too much water is not conducive to the growth of the grapes, causing the roots to suffocate, the new shoots are not full, the flower buds are poorly differentiated, and even the plants die. Grapes have different water requirements at different times. In the early spring germination, new shoot growth period, and young fruit expansion period, sufficient water supply is required. Soil grapes have strong adaptability to soil. Except for suitable growth in wetlands and heavy saline soils, all other types of soil can be cultivated, and fertile sandy loam is most suitable. Different soils have different effects on grape growth and quality. Disclaimer: Some articles on this website are transferred from the Internet.

The dry urine analyzer is mainly used to automatically evaluate the results of the dry test paper method. Because of its simple structure and convenient use, it is widely used in clinical practice.
(3) According to the degree of automation, it can be divided into semi-automatic urine analyzer and automatic urine analyzer.

Light grapes are hi-light plants, which require high light, and the length of light has a great influence on the growth and development of grapes. When the light is insufficient, the new shoots grow thin, the leaves are thin, and the leaves are light. Therefore, it is necessary to improve the wind and light conditions of the frame in time.
(2) According to the classification of test items, it can be divided into 8 items, 9 items, 10 items, 11 items, 12 items, 13 items and 14 items. The testing items included urinary protein, urinary glucose, urinary pH, urinary ketone body, urinary bile erythroplasm, urinary bile gen, urinary occult blood, nitrite, urinary white blood cell, urinary specific gravity, vitamin C and turbidity.
The "fake death" phenomenon of grape seedlings means that the grape seedlings do not grow, germinate, or grow in a short period of time, but the branches themselves are soft and green, and there is no dryness. The "fake death" of grape seedlings will affect the production of grapes next year or even the next year, so it is necessary to strengthen the management of grape seedlings and timely remediation.
