In order to control the growth of plants, extend the harvest period, and play a role in promoting roots and strong trees, most vegetable farmers will “press the vines†on the prosperous plants and control the growth of the top. However, after the tomatoes are pressed, the vines should be hung in time. Many vegetable farmers still have no vines when the tomato plants grow to 60-70 cm in height, and the plants are sloppy, which is not only unfavorable for farming operations, but also not conducive to the formation of strong trees. Moreover, most of the stems and leaves of plants that are not hanged in time are attached to the ground. After watering or under cloudy weather, the humidity is too high, and the bacteria in the soil can directly spread from the contacted ground, and even cause the stalk to rot. .
Therefore, here to remind the vegetable farmers to pay attention, we must hang the tomatoes in a timely manner.
When the plants that have been pressed are hanged, the plants should be hung on the steel wire in the direction of pressing the vines. The stems should not be lifted too high to avoid damage to the adventitious roots, forming a large number of wounds, creating opportunities for pathogen infection. After hanging the vine, it can not only improve the ventilation and light transmittance between the plants, but also reduce the occurrence of diseases, which is also conducive to the operation of farming.
Hanging vines are generally carried out when the tomato plants grow to 30-40 cm.
The traditional tomato hanging method is to fix the upper end of the sling on the drawn sling wire and the lower end on the tomato plant.
This method of hanging vines often occurs as the stalk becomes thicker and the fruit set increases. The slings tend to “leave†into the tomato stalk, affecting the normal transportation of nutrients and water, and even breaking the stems, affecting the normal development of the plant. . In addition, it is laborious and labor intensive, increasing production costs.
New method of hanging vines:
Under the corresponding hoisting wire that has been pulled, and then 20 cm from the ground, pull a wire along the planting line. When hanging the vine, fix the upper end of the sling on the sling wire, and the lower end is 45-60 degrees, and the cable is fixed obliquely on the lower wire.
Then the tomato stems are directly coiled on the sling, no need to squat on the stalk. This not only avoids "straining" the stem, but also makes it easy to handle when it is falling. For parks with large cultivation areas or large production households, you can use the idle time to tie the slings in advance, so that the tomatoes grow up and then stalk the stalks on the slings, effectively reducing labor pressure.
