1. According to cucumber, tomato fertilization in different fertility stages, tomato seedlings must ensure that the absorption of normal nutrients, fertilizer should be less, the concentration should be low; full fruit fertilizer should be large, the concentration must be larger. Some farmers use 200 kg of diammonium phosphate at a time. It is unscientific to try to obtain high yields by diammonium alone. 2. Fertilization according to the soil conditions If fertilizing with water, the amount of soil should be taken into account. The soil is dry, the concentration is low, and the amount of topdressing is more. When the soil is moist, the concentration is higher and the amount of fertilizer used is less. Sandy soil has poor water retention and fertility, and it has to be applied in small quantities. The viscous soil has strong water retention and fertility, and the frequency of fertilization should be small, but the amount of fertilizer applied each time should be more. 3. Fertilization according to weather changes. Temperature will affect the endurance of the roots to the concentration of fertilizers. When the temperature is high, the concentration of fertilizers should be low, otherwise rooting may occur. When the temperature is low, the concentration should be larger, so fertilization should be changed according to the weather. 4. According to different types of fertilizer to take different methods of fertilization in the topdressing fertilizer, the ditch should be taken to concentrate the effect of fertilizer, timely cover after fertilization to prevent nutrient volatility to reduce fertilizer efficiency, dressing N fertilizer should be 10 cm away from the roots of the plant Outside, avoid burning roots. Composting with irrigation can increase fertilizer efficiency. In general, the amount of basal fertilizer for cucumber and tomato is approximately equal. The amount and quantity of fertilizer used for cucumbers and tomatoes in one mu of greenhouse are: 3000-4000 kg of decomposed manure or 520-640 kg of avermectin organic fertilizer can be used (with the exception of organic fertilizer, abamectin can no longer use chicken manure. Generally 40-50 kg of avermectin organic fertilizer can replace 500-800 kg of chicken manure, 40 kg of diammonium phosphate, 100 kg of pure potassium sulfate, 30 kg of urea, 4 kg of Indian calcium fertilizer, 3 kg of borax, zinc sulfate 1.5 Kg, 40 kg of microbial agents. Sprinkle the above fertilizer deep into the ground. Microbial microbial agents can be applied in the form of ditching and acupuncture, and they can be used centrally during transplanting.
