In the cultivation of tomato, in addition to the collaterals that should be retained, the operation of removing all the remaining lateral branches is called snoring. Scientific snoring is a very important part of high-yield cultivation of tomatoes. However, many vegetable farmers do not pay enough attention to this aspect and think that it is irrelevant, causing a series of adverse consequences. Therefore, pay attention to the following matters when you fight.
(1) Pay attention to the growth rate of crickets and do it at the right time. The approach of vegetable growers is often whether they are large or small, and they will fight when they meet. Of course, too late snoring and excessive consumption of nutrients will affect fruit set and fruit enlargement. However, in the early stage of tomato growth, the volume of nutrient assimilation of the plant is small, and snoring is too early, which affects the growth and development of the root system, resulting in slow growth and a decrease in the resulting force. Especially early-maturing varieties and weakly growing varieties became more pronounced. The correct course of action should be to remove the disease in stages and grades when it grows to about 7 centimeters. For the weak plant growth, if necessary, 1-2 leaves should be kept on the pods and then hit the heart to ensure that the plants grow robustly.
(2) Grasp the time of war. In 1 day, it is best to choose snoring during sunny high temperatures. In the morning, the snoring caused excessive flow of blood and caused the loss of nutrients. At noon the temperature was high. After the snoring, the wounds healed quickly and there was less wound flow. If the snoring occurred after 4 o'clock in the afternoon, the wounds were easily infected by bacteria during the night.
(3) Do a good job of disinfection before snoring to prevent cross-infection. Because the hand, especially the smoker's hands, often have tobacco mosaic virus and other harmful bacteria, such as incomplete disinfection can easily cause a large area of ​​infection. Therefore, beforehand, hands and scissors should be thoroughly cleaned with soapy water or disinfectant. When burping, be selective. That is to say, first hit a healthy and disease-free plant, then hit the affected plant, and the remaining debris should be piled up, then clean up and buried, and avoid throwing it away.
(4) Appropriate retention. Many farmers have wiped their hands from the base when they fight. The disadvantage of this approach is that in the event of pathogenic infection, pathogens quickly spread to the trunk along the wound, and the wound is large and unfavorable for wound healing. The correct approach should be to leave a 1-2 cm high file at the base of the cockroach when it is in force, which effectively prevents germs from invading the trunk from the wound. It can also make the wound small and help the wound heal.
