After the autumn, the strawberry should be applied to the base fertilizer.

It is now in the autumn, generally from the end of August to the end of September, the best time for greenhouse strawberry planting. Strawberry has a high demand for fertilizer and water, so farmers should apply enough and apply basic fertilizer.

Soil testing and fertilization techniques were used to determine the fertility status of the soil before planting, and according to the fertilizer characteristics of the strawberry, a reasonable balanced fertilization plan for the whole growth period of the strawberry was formulated, that is, balanced fertilization of the soil test formula, and balanced application of nitrogen, Phosphorus and potassium three-factor fertilizers, combined with medium and trace element fertilizers, determine the ratio of base fertilizer and top dressing.

The organic fertilizer is mainly based on organic fertilizer, and the appropriate fertilizer is applied. From the point of view of the fertilizer absorption of strawberry, it is necessary to absorb a large amount of fertilizer in the later stage, especially phosphorus and potassium fertilizer. The decomposition process of organic fertilizer shows that a large amount of phosphorus and potassium are released in the later stage, which can meet the growth demand of strawberry. Apply 3,000 to 3,500 kilograms of fully decomposed organic fertilizer per acre or 400 to 450 kilograms of commercial organic fertilizer. At the same time, add 3-5 yuan compound fertilizer 15 ~ 20 kg or urea 5 ~ 6 kg, diammonium phosphate 15 ~ 20 kg, potassium sulfate 5 ~ 6 kg.

In principle, bio-organic fertilizer should be used as a supplementary strawberry. Otherwise, it is prone to root rot, verticillium wilt, and bacterial wilt. Therefore, the greenhouse must be disinfected by the soil to compensate for the loss of beneficial microorganisms in soil disinfection. Apply bio-organic fertilizer, the application rate is 100-150 kg per mu. Bio-organic fertilizer is rich in organic matter and a variety of beneficial microorganisms, which can improve soil structure and physical and chemical properties, and provide sufficient nutrients for crop growth to enhance the availability and absorbability of soil nutrients.

When applying the base fertilizer, it is recommended that the farmers carry out the soil when plowing, and the depth should be about 20 cm to ensure the uniform distribution of the fertilizer and remove the hard soil, stones, weeds, broken film and other debris.
