Since entering the winter, the weather between the sunny and the yin has brought serious impacts on vegetable production. The unfavorable conditions of unstable temperature, insufficient illumination time and low ground temperature have become important factors restricting the high yield and stable yield of vegetables. Roots are the basis and key to crop growth, and the roots of conservation have become an important part of stabilizing the growth and yield of vegetable crops during this period. The rooting agent plays an extremely important role in the process of curing the root system. However, there are many varieties of rooting agents currently on the market, and how to correctly recognize, select and use rooting agents has become an important issue for the current farmers.

The rooting agent is an auxin compound belonging to the plant growth promoter. In the vegetable production application, there are a plurality of components such as indole acetic acid, indolebutyric acid, naphthalene acetic acid, etc., and the role thereof is to maintain the apical superiority of the plant in the plant, and induce Assimilation products are transported to products (fruits) to promote rooting of plants.

At present, the rooting agents on the market can be mainly divided into the following three categories: common rooting and seedlings (single-type compounds such as acetic acid and naphthaleneacetic acid or a mixture of the above-mentioned compounds according to scientific ratio), biological bacteria and Rooting agent compounding rooting agent (ABT biological rooting powder), nutrient elements and growth promoters compounding rooting agents (such as root dense, Fang Rungen, etc.). What are the differences between the three types of rooting agents?

The first common rooting seedlings are suitable for vegetables at the seedling stage and late growth stage. After use, it can obtain obvious effects in a short period of time, and the effect is rapid, but it is best not to use it continuously, otherwise it may cause adverse symptoms such as longevity and premature aging of vegetable crops.

The second type of rooting agent products are suitable for the initial stage of the results and the early stage of crop growth, and the effective combination of the biological bacteria and the rooting agent can play a "double effect" role. The derivatives of the biological bacteria in the growth and reproduction process can optimize the growth environment of the root system and slowly stimulate the growth of the root system. The rooting agent stimulates the root growth, and the combination of the two increases the nutrient absorption capacity of the roots of the plant, which is consistent with the growth of the vegetable crop. The early growth characteristics also meet the nutrient requirements of crops during vegetative growth and reproductive growth.

The third type of rooting agent product combines the characteristics of the above two. It can be applied throughout the entire crop growth process.

In the application process, the rooting agent should be selected according to the growth condition of the crop itself and the occurrence of bad weather, and the rooting agent should be selected according to the current growth state of the vegetable. Before use, determine the dilution concentration and method (irrigation or water application) in strict accordance with the instructions. Appropriate concentration can significantly improve the growth state of crops, promote the robustness of roots, and enhance the absorption capacity of roots. Otherwise, not only will not be able to achieve good results, but also easily lead to adverse conditions such as hormone poisoning and premature aging of plants.

Rooting agents are different from fertilizers, and the two cannot substitute each other, but they complement each other. After the rooting agent is absorbed by the crop, pay attention to timely supplement the nutrients needed by the crop to prevent de-fertilization.

Ball Valve

Ball valve is evolved from the plug valve, its opening and closing parts as a ball, using the ball to rotate 90 degrees around the axis of the stem to achieve the purpose of opening and closing, the difference is that the cock body is a ball, with a circular through hole or channel through its axis. The ratio of the sphere to the passageway should be such that when the ball is rotated 90 degrees, the inlet and outlet should be completely spherical, thus cutting off the flow.

The role of ball valve in the pipeline is mainly used to cut off, distribute and change the direction of media flow, designed into the V-shaped opening ball valve also has good flow regulation function.

Ball valve is not only simple in structure, good sealing performance, but also in a certain nominal range of small volume, light weight, less material consumption, small installation size, and driving torque is small, easy to operate, easy to realize rapid opening and closing, is one of the fastest developing valve varieties in recent decades. Especially in the United States, Japan, Germany, France, Italy, West, Britain and other industrial developed countries, ball valves are widely used, the variety and number of use is still continuing to expand, and to high temperature, high pressure, large mouth, high sealing, long life, excellent regulatory performance and a valve multifunctional direction, its reliability and other performance indicators have reached a higher level, And has partially replaced Gate Valve, Globe Valve, Regulating Valve.
