Tomatoes make good use of fertilizer to promote high yield
Tomatoes, scientific name tomatoes, rich in a variety of vitamins and nutrients, whether it is directly or after cooking to eat, are very popular. Therefore, more and more vegetable growers grow tomatoes, so that people can eat delicious and delicious vegetables all year round. However, no matter what kind of crops are planted, the ultimate goal is to increase the income of the economy. Therefore, it is very important for the tomatoes to be able to produce high yields. The tomatoes are also deep-rooted crops. The root system is relatively developed, and the distribution is wider and deeper. The soil absorbs a lot of nutrients, mainly nitrogen, phosphorus and potassium. It can be seen that the importance of fertilization on tomatoes, tomato fertilization can be summarized as follows: the main base fertilizer, supplemented by top dressing; to re-applied high-quality decomposing organic fertilizer, supplemented by inorganic fertilizer. The following fertilizer application methods for the whole growth period of tomatoes are described below for your reference. 1, seed fertilizer. To obtain higher yields, it is necessary to start from “small†and fertilizing the seeds is also very important. The fertilization of seeds mainly refers to the use of microbial fertilizers and seed dressing. Bacterial fertilizer seed dressing can not only ensure the nutrient required for seed germination, but also can provide a good soil environment for the germination of seeds, which is conducive to raising seedling rate and cultivating strong seedlings. Two problems should be paid attention to when dressing seedlings with bacteria: (1) Select qualified quality of fertilizer. The inferior bacteria fertilizer is harmful to the seeds and it is useless. Do not use it. Should choose to have a reliable technical background and technical sources, quality and performance of a stable fertilizer, such as the microbial microbial fertilizer. 2 Minimize microbial death. Fertilizer should avoid direct sunlight, and should be operated in the shade during seed dressing. Seed should be sowed immediately after dressing, and immediately cover soil. Fertilizer can not be mixed with harmful pesticides and chemical fertilizers. 2, Miao Fei. The growth of seedlings can affect the whole growth period of tomatoes, especially for flower bud differentiation. Therefore, nurturing strong seedlings is the key to achieving high yields and cannot be ignored. Phosphate fertilizer at the seedling stage can provide early results. Appropriate application of root seedlings can promote root elongation, increase boldness and lateral root formation, enhance root activity and absorption intensity, and form strong seedlings as soon as possible, which is conducive to transplanting. 9 square meters of seedbed can be applied to sieve organic fertilizer 200 kg (preferably with goldfish fermentation auxiliaries fermented organic fertilizer), superphosphate and potassium sulfate 0.5 kg each; when the tomato seedlings grow to 4 to 5 tablets When leaves, if the lower leaves are light in color, they can be sprayed with 0.1% to 0.2% of potassium dihydrogen phosphate or urea, which can guarantee strong seedlings. 3. Reapply base fertilizer. Reusing high-quality organic fertilizer as a base fertilizer can not only provide the nitrogen nutrition needed in the early stage, but more importantly, the organic fertilizer can supplement the deficiency of ammonia, phosphorus, potassium, calcium and some trace elements in the soil. 1 organic fertilizer. In the general level of soil fertility, can be used to spread high-quality rotten farmyard fertilizer 7000 ~ 8000 kg / acre, deep-turn 40 cm, and then overturned again, doped with fertilizer, fine leveling. Ditch depth 10 to 15 cm, and apply over calcium phosphate 20 to 30 kg/mu or diammonium phosphate 20 kg/mu, urea 10 kg/mu, potassium sulfate 20 to 30 kg/mu. . Special attention should be paid to the fact that the organic fertilizer must be fully decomposed, and it is best to treat it with a professional Gumbol starter. This will not only reduce the loss of nutrients, but also completely eliminate organic pathogens such as germs and eggs. 2 bacterial fertilizer. Biological bacterial fertilizer not only contains a large number of nitrogen-fixing, phosphate-solubilizing and potassium-releasing active bacteria, but also contains humic acid, organic matter and various trace elements. In particular, high-quality biological fertilizers (such as golden baby microbial fertilizers) can be applied in combination with other fertilizers in any fertilizers needed for tomatoes, which not only saves fertilizer use, but also solves soil compaction and increases soil microbial content. . Fourth, skillfully applied fertilizer. Tomatoes should not be over-dressed in the early stages and the results should be heavy afterwards. The principle of topdressing is: from less to more, from lean to strong; in the early stage, nitrogen is dominant; in the later stage, phosphorus and potassium are mainly used; diluted manure water and chemical fertilizers are alternately applied; soil drought is easy to be top-dressing, and the soil is moist and easy to concentrate. Generally, every tomato receives 1 fruit, chase 1 fertilizer, top dressing 3 to 5 times. The goal of fertilization is to promote fruit growth, coordinate vegetative growth and balance of reproductive growth, promote control and integration, promote early results, achieve multiple results, and produce large fruits. 1 Light-weighted tree-fertilizer: After watering the seedlings, watering is started and the first time the tree-fertilizer is traced. In this period, seedlings just need seedlings for nutrients and they need roots, stems and leaves to grow. At the same time, lack of nutrition during this period will affect vegetative growth and flower bud differentiation, resulting in reduced production. After planting seedlings, nitrogen nutrition is predominant, and it is better to chase after fruiting of the second ear fruit, which will promote early results and high yield. It is generally 10 to 15 days after planting, and the combined application of water to topdressing human excrement 500 kg/mu, or urea 10 kg/mu, or ammonium sulfate 20 kg/mu. 2 heavy application of fruit fertilizer: the second time is to promote fruit fertilizer, adjust the reasonable distribution of assimilation products, and coordinate the relationship between leaves and fruit. When the fruit of the first panicle begins to enlarge, the ability of roots to absorb nutrients is strong. At this time, the supply of nutrients is very important, and it is also a key dressing period for tomatoes in their lifetime. The main nitrogen fertilizer, and with phosphorus and potassium fertilizers. Generally 667 square meters of DAP 10 ~ 15 kg, or ammonium nitrate 15 ~ 20 kg, can also be applied to make a good cake sap or decomposed dilute human urine (treated by goldfish starter), with water Shi, 500 ~ 800 kg / acre, and apply about 10 kg of potassium sulfate. 3 Qiao Shi Sheng Fruit Fertilizer: The third time is Sheng Fruit Fertilizer. After harvesting the first panicle fruit, the second panicle fruit is applied when it is swollen. Due to the prosperous long-term growth of tomatoes, it is necessary to have more fertilizer and water, otherwise it is easy to drop flowers and fruit. The amount of fertilizer used during this period should be large, and special attention should be paid to the use of phosphorus, potash and trace element fertilizers. Generally, 667 square meters of Shi Sanyuan compound fertilizer or 40-50 kg of diammonium phosphate, or decomposed rare human fecal urine or brewed good bean cake fertilizer 1000-1500 kg, with water flushing. 4 Appropriate application of relay fertilizer: greenhouse cultivation in winter and spring or autumn and winter, the late varieties of tomatoes, the results of a long period, high yield, the amount of fertilizer required. Therefore, it is also very important to apply the fourth or fifth fertilizer in a timely manner. It can promote the renewal of the old strains in the later period of the tomatoes, and timely market the fourth to seventh ear fruits from March to April in the coming year, supplementing the off-season vegetables, yielding high quality products. Generally every time every 667 square meters topdressing Sanyuan compound fertilizer 30 ~ 50 kg, or diluted manure fertilizer 1000 ~ 1500 kg. 5 Foliar fertilizer: In order to improve the quality, prolong the result period, prevent premature aging, the results can also be followed by foliar dressing, fertilizer efficiency, low cost. Should be selected sunny evening or after the rain spray sunny days 0.2% ~ 0.3% potassium dihydrogen phosphate or gold baby bacteria fertilizer, 2 ~ 3d after spraying, leaf color turn dark green, improve fruit quality. If umbilical rot fruit occurs, 0.5% calcium chloride can be sprayed in time and sprayed several times. The control effect is significant. Fifth, sweetening coloring fertilizer. Color and taste are the main criteria for measuring the quality of tomato fruits, and are also important factors that affect the unit price of tomatoes. After the flowering of the tomatoes, the sweetening coloring fertilizer (Gumba Sweetening Coloring Agent) shall be applied in a timely manner. The main effects are as follows: 1 Preserving the fruit and protecting the fruit: The use of the early stage can overcome the adverse environmental conditions such as low temperature, low light, etc., and prevent flowering and fruit falling. To protect each other's purpose. 2Sweetening and coloring: It can promote the enlargement of tomato fruit and supplement many kinds of trace elements needed for fruit growth in the middle and later period; it can prevent cracking and increase the soluble solid content of fruits; increase the sugar content of fruits by 0.8-1.5 degrees, promote the early coloring for more than 10 days. The color is deep and even; at the same time, it can increase the hardness of the fruit and extend the storage period. For details, please contact: Beijing Huaxia Kangyuan Technology Co., Ltd.
