Regulate base fertilizer and top dressing. Generally, the base fertilizer should account for 60% of the total fertilizer application, and the phosphorus applied by the base fertilizer can account for 70% of the whole growth cycle. The high-quality farmyard manure and manure should not exceed 5000 kg per mu.
Add organic fertilizer. Organic fertilizer can improve the soil water and fertilizer retention capacity, and can also adjust the soil pH and balance, and avoid the soil due to concentrated fertilizer.
Shallow top dressing is prohibited. The vegetable sealing performance of greenhouse vegetables is better, and shallow top dressing or spreading fertilizer is extremely volatile and harmful to vegetables. When topdressing, it is necessary to apply or apply a hole at a depth of 5 to 6 cm, and keep a distance of 8 to 10 cm from the root of the vegetable.
Apply nitrogen fertilizer at a suitable temperature. The application of nitrogen fertilizer should be carried out around noon on sunny days. If it is too late, it will reduce the effect of topdressing due to low temperature. When applying nitrogen fertilizer, it is best to use a 0.5 to 1% urea solution at 15 °C or higher.
