Spring citrus is always curled up, what happened?

Recently, many citrus groves have experienced the situation of rolling leaves. Here, for the sake of simple summary of several reasons for the roll, although it may not be very comprehensive, but can be analyzed from these aspects, looking for reasons.

First, the coiled leaf caused by nematodes

In the second year, the fruit field without fruit was buried with winter fertilizer, water and fertilizer and foliar fertilizer. The same tree is rolled on one side, and the leaves are not rolled on one side; the roots on both sides of the rolled leaf and the non-rolled leaf are all showing serious root-worm; although there is no leaf on the right, it is believed that the nematode is not solved and will soon appear. The situation of rolling leaves.

This orchard is even more obvious. The management of water, fertilizer, pests and diseases in the whole orchard is relatively good. The overall tree potential is also very good, but when you walk into the orchard, you can see a lot of rolled leaves; some are whole leaves; some are While rolling leaves and yellowing, one side is normal; some are also normal. A few whole rolled leaves and some rolled leaves were randomly excavated, and the root nematodes showed very obvious performance, and the typical nematode harmed the root system.

Second, the fruit leaf caused by the de-fertilization

In the fifth year, the fruit trees were hanged, the winter fertilizer was not buried, the trees were weak, the whole garden was severely curled, and some of the leaves were yellow; the root system was dug, the roots grew well, and the soil was not dry; then the orchard was probably not timely after harvesting. Supplementing nutrition, restoring tree potential, resulting in loss of nutrients leading to leaf rolling. It is recommended to use water-soluble fertilizer for about 15 days, and the leaf surface should be supplemented with trace element fertilizer such as boron and zinc.

Third, the roots caused by broken roots

Roots on both sides

Four roots

This time is also the same orchard. The above tree is rooted on both sides, showing that the leaf is not obvious, and the four-direction short root is quite serious. Of course, the whole orchard is also accompanied by a worm, which may be caused by both reasons. There is existence.

Fourth, the leafworm caused by aphids

This kind of curling leaf is very clear to everyone, and it usually appears on the young shoots, which is very easy to distinguish.

Five other reasons

1. Boron deficiency, which causes curling when boron is absent, accompanied by veins protruding;

2, the cold spring, the temperature difference between day and night leads to the rolling leaves; when the spring colds in the past year, the leaf curls caused by the young leaves

3, fertilizer damage, roots and other causes root damage, insufficient nutrient absorption can also lead to citrus leaf problems.

POLELINE HARDWARES

Pole line hardware refers to a range of products and accessories used in the construction and maintenance of overhead power lines. It includes various components such as pole brackets, crossarms, insulators, guy wires, and clamps that are essential for supporting and securing the electrical cables to utility poles. These hardware items are designed to withstand the weight and tension of the power lines, ensuring their safe and reliable operation.

Yokelink supply a full line of Poleline Hardware, we offer from the top of the pole to underground. Here are some of the pole line accessories that you are likely to use for your project:

Pole Bands
A pole band is used as a point or platform for creating secondary racks to the pole. It is sometimes referred t as a fastening clamp or simply a pole fastener.
Guy Wire
Also known as a stay wire, this hardware is usually used for enhancing the stability of the pole. It balances the load that is on the electric pole.
Stay wire is usually assembled with other accessories such as pole bracket, guy thimble, and stay rod so that it can attach to the pole and ground.Guy wires must have high tensional strength to sustain the forces against it.
Anchor Rods
You will have to buy guy anchor whenever your project entails attaching guy wires onto the power line. The anchor plays the role of connecting the guy wire to the ground.A guy anchor should be strong and have adequate tensile strength to support the force of the wire.

Guy Clamps
You will need the best guy clamp to secure the strands of guy wire. The clamp comprises two pieces of carbon steel that are designed to form a parallel groove.The design of the clamp ensures that there is minimum damage caused on the strands of the guy wires.
Guy Grip

Also known as a dead-end grip, this pole line hardware is usually used on the distributed cables. It is usually attached to the grip conductor and as well as for the optical fiber.A guy grip has helical which is capable of holding the cable.

Guy Thimble

Also known as cable thimble, this utility pole accessory is usually used in conjunction with guy grip. The thimble acts as an interface between the pole band and the guy grip.
It can also connect to the tension clamp in order to protect the ADSS cable. You can also use the guy thimble to connect the stay rod to the guy wire.
Insulator Clevis

A secondary clevis comprises of a punched steel and a clevis pin. It is also known as dead-end clevis and is characterized by the D-shaped bracket. The main function of this powerline accessory is to connect with the pool insulator to the pole.Apart from the overhead line, this accessory is also used on the dead end.

Secondary RackSleepless_page34

As overhead line hardware, a secondary rack works as a platform for holding insulators. The u-shape design of the rack allows it to support the maximum number of insulators at any given time. It all depends on the number of spools that are on the rackThe smooth edges of the rack do not scratch he attached insulators on the rack.
Crossarm Braces & Bracket
This utility pole hardware is literally the arm of a streetlight pole. It extends from the pole to provide a platform where you will attach the lighting fixtures.Streetlight arms come in different lengths and designs depending on the needs of the users.
