The longer the fruit tree is, the more prosperous it is.

The growth of fruit trees is weak, yellowing and wilting is always very worrying for fruit farmers, but if the fruit trees grow too prosperous, it will also cause low yield or no result. The main reason for this phenomenon is that the vegetative growth of fruit trees predominates and reproductive growth is at a disadvantage. Therefore, it is necessary to take corresponding measures to strengthen management to achieve the goal of high yield.

Broken root

The purpose of root cutting is to reduce the absorption of water and nutrients by roots and promote the reproductive growth of fruit trees. The practice is: dig a 60-70 cm wide annular groove along the vertical line along the outer edge of the canopy, cut the thick roots of the lower layer of the soil, and dry for 4-5 days, then mix the decomposed organic fertilizer with the topsoil. At the same time, combined with Qingyuan to cultivate the orchard to cut the soil, to cut off the absorption roots of the topsoil, reduce the transport of nutrients, increase the concentration of tree juice, and promote flower bud differentiation.

prune

Most of the fruit trees that are not fruitful are easy to extract new shoots because of excessive growth, and the branches of these fruit trees are numerous and chaotic, and the illumination is poor, and the result is moved outward. Therefore, part of the strong shoots in the upper part of the canopy should be cut off, and a part of the drooping branches and overlapping branches should be removed to make the crown get sufficient sunlight and enhance the accumulation of effective nutrients in the tree.

Ring cutting

Cut 1-2 turns on the main branch or the main branch that grows too badly, and go deep to the junction of the phloem and the xylem, without damaging the xylem. In this way, the nutrients produced by the leaves are no longer transported downwards, and all accumulate at the upper end of the incision, so that the shoots have sufficient nutrients.

In addition, it should be noted that the application of nitrogen fertilizer and excessive watering should be strictly controlled for such fruit trees. (microbial fertilizer)

ADVANTAGE & CHARACTERISTICS

1.Much higher adhesion between coating & substrate

2.PE & PVDF paint , high durability & wide applications

4.Distinct & vivid texture

The Prepainted Steel Sheet in coil is a product obtained by subjecting a hot dipped galvanized steel sheet, and galvalume steel sheet, or an aluminum sheet to a surface chemical treatment (coating) , followed by baking and curing.

  • The total thickness of the pre-panted galvanized steel coil is composed of the base steel – coating -primer – top paint – protective layer thickness. The top paint thickness is 15-25μm, and the back paint thickness is 5-20μm. The thinner the base steel thickness, the higher the price of the Ppgi Steel Coil , because the processing cost becomes higher.
  • Usually the paint coating material is polyester (PE) and the color of the back paint is white grey. The color can be customized according to the RAL color card or customer samples. Special patterns can be made, such as wood grain, flower print, camouflage, brick.

1) PPGI also known as Prepainted Galvanized Steel coil and color coated steel coil, with a hot dip zinc coated steel sheet substrate.

2) PPGL also known as Prepainted Galvalume Steel Coil, with a galvalume steel sheet as a substrate.
