The growth and development process of radish includes two stages: vegetative growth and reproductive growth. The vegetative growth is divided into germination stage, seedling stage, leaf growth stage, fleshy root growth period and dormancy period, in which the fleshy root expansion period is the maximum period of nutrient.
The radish has strict requirements on water during the growth process. In the period of meat root formation, such as soil water shortage, it will cause the radish skin to be rough, the spicy taste is increased, the sugar and vitamin C content is reduced, and it is easy to worry. If the soil moisture content is too high, it will cause the radish skin to be rough and form irregular protrusions. The radish is not strict with the soil conditions. The soil layer is deep, the water retention and drainage are good, and the loose and breathable sandy loam is suitable.
Although the cultivation technique of radish is very simple, the heart disease that occurs during storage is caused by the lack of phosphorus and potassium, so it should be combined with fertilization to prevent it. The principle of fertilization of radish is: organic and inorganic combination, NPK balance. The specific fertilization methods are as follows: 1. Base fertilizer: On the basis of applying the mature organic fertilizer, the application of Tianji brand NPK fertilizer is about 30 kg. 2. Topdressing: In the period of succulent root expansion, the application of Tianji brand phosphate phosphate fertilizer is 25-30 kg.
Torpedo Levels are carpentry tools that are utilized to ensure that a surface
or angle is level or plumbed properly. The body of a torpedo level is rectangular in shape. With many
designs, the ends of the level are narrower than the middle section.
While all levels of this type will included at least one vial in the
middle section that is filled with some type of spirits, it is not
unusual for a multipurpose torpedo level to have up to three different
vials contained in the middle third section of the body. Multiple vials
or bubbles make it possible to check more than one angle at a given
time, which may be helpful when ascertaining the whether or not the
joint where two walls and a ceiling meet.
