Many people say that tomatoes are a particularly easy to grow vegetable? Do you agree with the vegetable farmers? Leafy vegetables, solanaceous fruits and other vegetables, fertilization management, climate impact, from seedling stage, dead seedlings, yellow leaves, more diseases, low yield problems. Although tomatoes are easy to grow, there are a few ways to ensure that the tomatoes are harvested. Planting tomatoes requires attention to the following aspects: First, planting In the case of the next seedling, the depth should be appropriate. If the seedlings are planted too deep, the deep sealing temperature is low, and the root growth of the seedlings is not good. If it is too shallow, although the temperature is reached, it can be rooted and unstable. It is easy to fall down when watering, or blown down by the wind. Second, cover the film It is now common to grow tomatoes using mulch film, which can increase the temperature in the soil, prevent excessive evaporation of water, and also inhibit the growth of other weeds. Third, the management of water Water is poured through the seedlings. Wait five to seven days after watering, and loosen the soil several times. When the results are about to be achieved, keep the soil moisture at 80%. Water is given every three to four days in the summer, and once every six to seven days at low temperatures. Fourth, fertilizer management If it is a small plant, you can carry out a top dressing when the fruit is a little smaller than the egg. If it is an elevated plant, it is necessary to carry out top dressing when the first, third, fifth, and seventh results are to the size of the egg. At the same time as watering, use organic fertilizer in combination with one thousand kilograms per acre. Fifth, temperature management Tomato does not like low temperature, its growth requires different temperatures at different times, the temperature is between 25 and 30 degrees when germinated, 15 to 25 degrees for seedling, and 13 to 3 when the result is Between ten degrees. Tomato fertilization management is as follows: 1. Rational application of organic fertilizer, adjustment of nitrogen, phosphorus and potassium fertilizers. Non-calcium soils and acidic soils should be supplemented with trace elements such as calcium, magnesium and boron; 2. According to crop yield, sorghum and soil fertility conditions, rational allocation of chemical fertilizer, most of the phosphorus fertilizer application, nitrogen and potassium fertilizer application; early spring growth should not be frequent top dressing, pay attention to post-flowering and late-stage topdressing; 3. Combine with high-yield cultivation techniques, promote rooting during seedling stage, and adopt the principle of “small number of times†to rationally fertilize fertilization; 4. The old shed with soil degradation needs to return to the field or apply high organic fertilizer with a high C/N ratio, reduce the application of poultry manure, increase the number of rotations, and achieve the purpose of removing salt and reducing the obstacles of continuous cropping; 5. When acidification of vegetables is serious, apply acidic soil conditioner such as lime in an appropriate amount. The amount of tomato applied is as follows: 1. Incubate the seedling fertilizer and increase the application of the decomposed organic fertilizer to supplement the phosphate fertilizer. For every 10 square meters of seedbed, 60-100 kilograms of decomposed poultry manure, 0.5-1 kilogram of calcium, magnesium and phosphate fertilizer, 0.5 kilogram of potassium sulfate, and 0.05 to 0.1% urea solution are sprayed 1 to 2 times according to the condition of the seedling. 2. The base fertilizer is applied with high quality organic fertilizer 2~3 square/mu. 3. The production level is 8000 ~ 10000 kg / mu: nitrogen fertilizer 30 ~ 40 kg / mu, phosphate fertilizer 15 ~ 20 kg / mu, potassium fertilizer 40 ~ 50 kg / mu. 4. The production level is 6000-8000 kg/mu: 20-30 kg/mu for nitrogen fertilizer, 10-15 kg/mu for phosphate fertilizer, and 30-35 kg/mu for potash. 5. The production level is 4000-6000 kg/mu: nitrogen fertilizer 15-20 kg/mu, phosphate fertilizer 8-10 kg/mu, potash fertilizer 20-25 kg/mu.
