1, high ridge planting many people in the summer planting tomatoes, are planted in flat beds or shallow groove cultivation. And after planting, in order to avoid weed damage, will also cover the black film, and in the high temperature and strong light environment, the temperature within the soil is very easy to rise, and in the agricultural operation, directly on the film. In this case, it will lead to the film clinging to the ground, resulting in the soil between the rows of platelets. The permeability of the soil becomes poor, resulting in the roots of the water and nutrient absorption is blocked, the plant's growth will also be weakened, reducing the speed of fruit expansion. So we must pay attention to the summer planting of tomatoes to high ridge planting.
Summer tomato technology management
2, cultivate strong tree in the summer planting tomatoes, pay attention to control the amount of fruit. If the lower part of the tomato plant to leave too much fruit, it will lead to too much nutrient consumption, easy to fall, affecting the later growth of flowers and fruits, so less fruit. Especially in the lower part of the plant, if the plant stalk is weak, then first remove the first spike of flowers, cultivate strong trees. Then increase the appropriate amount of fruit, and if the plant is strong, then the first spike of fruit can be left about 2, the second spike of fruit can be left about 3, and the upward spike of fruit left about 5. However, be careful to remove the first flower from each spike and not to spot flowers.
3, the whole branching and leafing many people in the summer in order to reduce the temperature, will choose to use the shade net, but this will easily lead to plant prolongation, tomato plant stalks are also prone to become weak, so to chemical control of the main. Available chlorophyll, multi-purpose azole, etc., to adjust the concentration of the drug with the changes in temperature and plant growth. In the summer time, try not to beat the leaves unless the plant branches and leaves are too lush, causing serious impact on the permeability of the plant. Then after the last fruit has sat on the top, at least two leaf heads should only be headed to shade the top fruit. Finally the tops must not be removed completely to avoid premature senescence.
4, shed cooling just said, the summer temperature is very high. So if it is planted in the shed, then we must pay attention to do a good job of cooling. You can reduce the temperature through ventilation, in addition to shading, water spraying and so on are the main measures to reduce the temperature. Be careful to cover the shade net in the time point of 10-15 o'clock every day. At the same time, you can spray the appropriate amount of cooling agent on the shed film and spray water inside the shed. If the hot weather is continuous, then small amounts of water should be poured into the furrows and ventilation should be done. Finally, if you don't cover the film, then you should carry out the work after watering, so as to avoid the lack of water to cause the soil to dry and crack, affecting the growth of the roots.
