(1) Juvenile Tree: Continue to clean up the garden and maintain the orchard irrigation and drainage system. Pruning is completed and the long autumn shoots are cut short. Over the trees, the overlapping branches, the dense branches and the short branches are cut short; the old trees are short before the buds sprout.
(2) Result tree: Continue to trim and apply heavy fertilizer. Pruning: For the purpose of restoration of tree vigor, pruning of high-yield and debilitating trees for successive years, when the spring shoots are sprouting, cut off the weak branches, branch pests and dead branches, and short-cut branches. The sparse plexiform "broom" branch, the weak branch of internal decay "staying pile" (branches with 2-3 buds) short; fertilization: expanding the soil and changing the soil, applying heavy fertilizer, digging deep trenches, deep 50 cm, width 20-30 cm, depending on the length of the ditch, the application of mixed fertilizer, 25-30 kg of compost, 0.5-1 kg of phosphate fertilizer, green fertilizer as the source of fertilizer applied; spray foliar fertilizer, can be combined with pest control Spraying.

Grasp plastic trim. Pruning is mainly used to improve the illumination in the crown. The upper part and the outer part are thinned, and the lower part or the inner part of the branch is short-cut and updated. The main focus is on light shear, which strives to provide light and air outside the crown. The aging tree is mainly updated. The young trees are mainly plastic and cultivate a high-yield tree. At the same time do a good job in the development of the new garden, seedlings planting Yi Shen (cover not married interface), timely watering after planting, and covered with weeds to facilitate survival.

After Yu Lichun applied spring fertilizer in stages. In order to promote the growth of spring shoots and fruit growth, adult trees account for about 30% of the total amount of fertilization in the year. Plant applied 0.8-1kg three yuan compound fertilizer. For Boron-deficient Garden, 0.1% borax was sprayed during flowering. Juvenile tree, to expand the canopy, thin fat diligence. In order to increase fruit weight and increase tree vigor, thinning should be carried out. It usually starts from the beginning of spring to March (the temperature is stable at 10 degrees or more) and starts at 2-3 times. First remove the frozen fruit, malformed fruit, pests and diseases, and then depending on the variety, tree vigor to determine the amount of retained fruit, stay strong and retain the election, the fruit should be distributed evenly in the crown.
4G Mini Camera Structural components
The main structures and components of the camera can be listed from the working principle of the camera:
1. LENS
Lens structure, consisting of several lenses, including plastic lens or glass lens
2. Image sensor
It can be divided into two categories:
CCD (charge couple device): charge coupled device
CMOS (complementary metal oxide semiconductor): complementary metal oxide semiconductor
3. Digital signal processing chip (DSP)
There are many DSP manufacturers, such as VIMICRO 301P/L, SONIX 102/120/128, ST (Logitech LOGITECH's DSP provider), SUNPLUS (SUN+focuses on the development of CIF and VGA for single chip, but the image quality is average), PIXART (original phase), PAC207, SQ930C, etc.
4. Power supply
Two working voltages are required inside the camera: 3.3V and 2.5V. The latest process chip can use 1.8V.
Some cameras also use video transmission lines for synchronous power supply without external power lines.
