Description

Electric scissors for cutting {ELECTRIC SCISSORS FOR CUTTING OUT THE SUPERFLUOUS FRUITS}

The present invention (Disclosure) relates to electric shears for harvesting, which enable thinning out too many fruits during fruit cultivation.

Here, background art related to the present invention is provided, and they do not necessarily mean prior art (This section provides background information related to the present disclosure which is not necessarily prior art).

In general, fruit development is achieved by a smooth supply of stored nutrients stored in the tree in the previous year, nutrients and moisture absorbed from roots, and carbohydrates produced from leaves. The size of the fruit is determined by the amount of carbohydrates produced by the leaves, provided there is sufficient nutrient storage and absorption of nutrients and water by the roots.

In addition, the development of fruit begins with flowering and fertilization. The growth rate is very slow during the early stages of the fruit, but the growth rate increases rapidly from the end of the fruiting process, reaching maturity and harvesting. It is known that the rate of growth slows down again.

Therefore, in order for fruit to develop normally, it is desirable to limit the number of fruits through red fruit.

These red fruits are works to help the early growth of fruits by preventing the consumption of unnecessary nutrients, and include both red flowers, which remove flower buds before flowering, and red flowers, which thin out flowers during the pre-flowering period. .

On the other hand, the ripper is divided into manual ripper and chemical ripper work, and the manual ripper work uses pruning (ripper) scissors. The enemy and devices that enable this are being developed and used.
