The high temperatures and rain in the summer, the tomatoes lose their weight. Therefore, the following countermeasures should be taken during the summer to prevent defeat. Change the cultivation method: change the flat ridge cultivation to ridging cultivation, to avoid the tomato root system by the stain. The plants that have been cultivated in peacetime can be combined with earth and graded to make them become ridgebacks. It is generally completed in 2 to 3 times of earth to prevent overdraw of primary soil and affect root absorption capacity. Changing the technique of pruning: When the first inflorescence is set, the first branch that grows below the second inflorescence replaces the trunk, and when it has two or three inflorescences, one side of the trunk is selected to be the main trunk. Such a continuous picking of the heart replaces the head, stimulating the plant to renew and grow, so that the plants are not defeated, and fruit set is more. Timely water supply fertilizer: water once every 7 days or so, and 15-20 days of top-dressing nitrogen fertilizer such as urea or ammonium nitrate, topdressing about 5 kg per acre. At the same time, spraying potassium dihydrogen phosphate solution on the leaves makes the plants robust and not too long. Timely prevention of pests and diseases: During the summer, tomato disease mainly has diseases and virus diseases. Carbendazim and zein zinc were used to dilute to 500 times liquid spray at a ratio of 1:1 for 10 to 15 days. Prior to the onset of viral disease, a 0.1% to 0.3% potassium permanganate solution is sprayed every 7 to 10 days to prevent viral disease. Timely drainage of water: tomatoes are afraid of flooding, watering in the morning and evening when the cool, immediately after the irrigation water to exclude the ditch.
