After the colonization of tomato cultivation
1. Time cultivator should be cultivated in time after cultivating and planting. Early cultivating and deep cultivating are beneficial to the improvement of soil temperature and promote rapid rooting and seedling growth. It is more important for early maturing. The cultivator should be carried out three to four times in a row, and the depth should be shallower than once. Promotes the growth of adventitious roots in the stem base and expands the root mass. 2, fertilizer and water management tomatoes need a larger amount of fertilizer, but also more fertilizer-resistant. After the planting of the seedlings, the seedlings should be applied once. Each mu can be used to compost 250-500 kg of manure or 10-12.5 kg of ammonium sulfate. When the fruit of the first ear begins to swell, the second fertilizer is chased. This time, the amount of topdressing should be increased, and should be combined with nitrogen and phosphorus. Urea 10-12.5 kg per mu, calcium superphosphate 20-25 kg, second fruit When it is quite large, it should be applied for the third time. The amount of fertilizer is the same as the second time. Can be supplemented with extra-root fertilizer, or foliar fertilizer, at the end of the result. 3, the plant can adjust the non-self-sealing type of tomato can use single-pole pruning or double-bar pruning. Single pole pruning: left 7 panicles per plant. The first 1-4 panicles, leaving 2-3 fruit per panicle; after the fifth panicle fruit, 3-4 fruit per panicle, the excess removed. Timely eradication of lateral buds and timely sparse thinning of fruit to maintain a uniform fruit. 4. Pest and disease control diseases mainly include early blight, leaf mold, gray mold, and ulcer disease. At the beginning of the disease, it can be controlled with Bordeaux mixture 1:2:200, 70% thiophanate-methyl 800- to 1000-fold, and 75% chlorothalonil 600-fold spray at the later stage. The insect pests mainly include cotton bollworm, cabbage caterpillar and aphid. Such as damage to leaves and fruit, with Tianrun insecticide No. 1 or Tianrun insecticide No. 2 on the cotton bollworm and cabbage caterpillar have better control effect. 5. There are many reasons for falling flowers caused by falling flowers and their prevention and control. To sum up, there are mainly the following two aspects: (1) Malnutrition caused by obstacles. (2) Obstructed flowering of reproductive development. To prevent falling flowers, we must fundamentally strengthen cultivation and management to cultivate strong seedlings, timely planting and pay attention to root protection, strengthen fertilizer and water management, prevent soil drought and water, ensure adequate nutrition to prevent excessive application of nitrogen fertilizer, timely plant adjustments.
