Friends who have planted tomatoes know that most of the tomatoes will be used to help the tomato grow during the tomato planting process. However, in the process of using the vitamins, some problems need to be paid attention to, otherwise serious consequences will occur.
The small fruit disease is caused by the fact that the farmers use the Zuojinsu (or Xiaofengwang) in the tomato seedling stage at a large dose and at a late time (generally in the “high-footed seedlingsâ€). Although the plant height is controlled, the ear development is also inhibited. At this stage, the “rooting and seedling method†should be adopted. The specific method is to use 500-800 times Gaomei applied organic humic acid active liquid fertilizer to irrigate the roots, each plant uses 100 ~ 150g pesticides , and spray Wanchun plant growth agent plus carbendazim or Luheng No. 1 to promote root development and improve Disease resistance. To this end, it is recommended that tomato chemical control should be based on nutritional regulation, and care should be taken to prevent the following.
"Splinter Fruit Disease": Using the chemical control, it can thicken the peel and make the flesh expand rapidly, thus forming "split fruit disease". Prevention of this disease should increase boron, calcium, and cooling. Specifically, in the tomato flowering period, spray 300-500 times of humic acid boron calcium or 300-500 times of high-beauty application, and use the small fertilizer to wash the root potassium.
"Green Top": Some farmers have increased the fertilizer and water temperature management, so that the fruit development is too fast, coupled with the uneven use of hormone spraying, resulting in uneven development of various parts of the fruit, forming "green top disease." The root cooling method should be adopted for control. Specifically, when the second and third panicles grow out of the tomato, the bio-organic fertilizer plus potassium sulfate compound fertilizer is applied to the ditch or the hole to promote the growth of the secondary roots, and the ability to absorb water and absorb water is cultivated, which lays a good foundation for the late growth stage.
"Small fruit disease": Because the farmers use the Zhuangsu (or Dwarf King) in the tomato seedling stage, the dose is large and the time is late (usually in the "high-footed seedlings"). Although the plant height is controlled, the ear development is also inhibited. . At this stage, the “rooting and seedling method†should be adopted. The specific method is: use 500~800 times Gaomei applied organic humic acid active liquid fertilizer to fill the roots, use 100~150 grams of liquid per plant, and spray Wanchun plant growth agent plus carbendazim or green hengyi No.1 to promote root development. And improve disease resistance.
Pot Rubber Bearing is composed of sliding plate,alloy steel sliding surface,bearing pot,PTFE disc,pot cover,vulcanized-in pressure seal,elastomeric pad and seal against moisture.The movement of the bearing is realization for the sliding between the alloy steel sliding surface and PTFE disc.The friction coefficient of sliding each other is reduced with increase of the pressure,friction resistance also reduces greatly under silicone grease lubricate,so this make a precondition for moving freely and low friction coefficient.The elastomeric pad in the bearing pot is in three directions force state.The steel bearing pot greatly reinforces the intension of elastomeric pad and PTFE.We J.S.Brown supplys Gpz Pot Bearing,TPZ pot bearing and so on.
