       Tomatoes are very sensitive to fertilizers. Too late too late, too little, too concentrated, are not conducive to tomato production. Therefore, rational fertilization is an important measure for high yield of tomato. The principle of “one control, two promotion, three sprays and four bogey†should be mastered.

      One control: Before the tomato is planted until the fruit is set, the topdressing technique should take control of topdressing and look at the seedlings. If the topdressing is too concentrated too much, the stems are thick and the leaves are dark green, causing the plants to grow, even Causes falling flowers and fruit. Therefore, in addition to the plant is seriously lack of fertilizer, slightly applied water manure or biochemical organic liquid fertilizer (500 times), generally should control the top dressing.

Second promotion: tomato seedling stage and harvesting period should be applied topdressing to promote growth and development. After the first inflorescence fruit set, and the fruit has walnuts, the plants should be branched, the young fruit should be inflated, and the flowering result should continue. The nutrient consumption is large. At this time, the quick-acting fertilizer should be applied rapidly 1-2 times. Generally, 30% concentration of human excrement or 5% sulfur compound fertilizer leachate should be applied to ensure that the plant does not de-fertilize and promote the rapid expansion of the young fruit. Nutrients must be continuously supplied to meet the growth needs, otherwise it will cause post-fertilization, which will affect fruit development and cause premature aging of plants. At this time, the method of diligence and fierce protection should be adopted. Generally, 40% concentration of human excrement or 5% sulfur compound fertilizer leachate is applied every 10 days on sunny days. Linyi Fertilizer Network Copyright
        Three sprays: Tomato not only absorbs nutrients from the soil from the roots, but also absorbs mineral nutrients and sugar from the leaves to promote the development of fruits and seeds. Therefore, during the fruit growth period, especially when the continuous continuous rainy season cannot be used for underground top dressing, it should be carried out 2-3 times post-leaf spray fertilizer, which can be sprayed with 500-300 times liquid of biochemical organic liquid fertilizer, and can also be used for chelate multi-composite micro Fertilizer 500 times spray to improve the quality of the tomato.

Four bogey: tomato topdressing, avoid using high-concentration fertilizer, avoid fertilizing soil, avoid fertilizing under high temperature conditions at noon, avoid excessive concentration of fertilization, one is easy to make plants long, the second is easy to produce fertilizer, wet soil fertilization, causing falling flowers, Physiological diseases such as defoliation and fruit drop are fertilized under high-humidity conditions. Due to high soil temperature and high evaporation of plants, after fertilization, the plants will be prevented from functioning due to normal operation of the plants. Wet fertilization and high temperature conditions can also cause bacterial wilt. Fertilization time should be carried out in the morning or evening. Linyi Fertilizer Network Copyright
