How do strawberries use bio-organic fertilizer?

Strawberry is a fruit-edible plant with bright red, bright and juicy fruit, sweet and sour taste, and high nutritional value. It grows from Heilongjiang in the north to Guangdong in the south, and from Shanghai in the east to Xinjiang in the west. In the year of the year, the physiological function of the organs varies with the seasons. Generally, they are divided into five stages: the initial growth period, flowering period, vigorous growth period, flower bud differentiation period and dormancy period. .

The strawberry roots are fibrous roots with a shallow distribution, and 70% of the roots are distributed in 20 cm deep soil layers. Strawberries are hi-water, hi-fertilizer crops that require strong soil and water retention, good ventilation, and loose texture. Appropriate fertilization should be applied throughout the whole growth period to ensure that the plants grow robustly, flower more, have more fruit set, good fruit taste, and high yield. Strong seedlings are the basis for high quality, high yield and high efficiency. Strong seedlings accumulate nutrients in the body, the root system is developed, the plant survives quickly, and the flower buds have multiple and full differentiations, which can produce large and numerous fruits. Applying basal fertilizer is the basic condition for strawberry seedlings.

Strawberry is a perennial herb that requires N, P and K, trace elements such as boron, magnesium, zinc, iron and calcium. Fertilizers require different fertilizers at different growth stages. Phosphorus is required in the early stage, nitrogen is needed in the early and mid-term, and potassium is needed during the entire growth period.

Before the selection, it was not a crop of tomatoes, potatoes, eggplants, peppers, beets, peas, etc., and it contained a lot of organic matter and various minerals. Prepare soil before planting, deepen the soil 30--40 cm, and apply base fertilizer while deep turning. General Mushi biological organic fertilizer 200 kg, with 10 kg of urea, superphosphate 20-25 kg, potassium sulfate 10 kg. Based on the application of basal fertilizer, 20 kg of biological organic fertilizer was applied to the north after the strawberry was colonized or survived, which promoted root growth of the plant. In Jiangsu and Zhejiang, top dressing was applied after the planting. In mid-November or early December, 20 kg of bio-organic fertilizer was applied. (Note: Due to the fact that bio-organic fertilizers on the market contain a large number of different elements and different numbers of microbial bacteria, the specific dosage needs to be determined based on the specific content of the product, and there is technical guidance.)

Solution

Whether bio-organic fertilizer can be used as top-dressing Top-dressing is a fertilization method used to timely supplement the staged needs of nutrients during crop growth and development. Topdressing can promote crop growth and increase crop yield and quality.

Bioorganic fertilizer topdressing methods include deep soil and top dressing. Deep soil application generally applies bio-organic fertilizer near the root-dense layer, and timely soiling after application (bio-fertilizer is sensitive to sunlight ultraviolet rays) so as to avoid causing nutrient volatilization and loss of active bacteria. The top dressing is to mix the bio-organic fertilizer with 10 times of water evenly, take the supernatant after standing still, and use the sprayer to spray the fertilizer solution on the front and back sides of the crop leaves for absorption by the foliage.

Considering the cost of bio-organic fertilizers recommended - fertilization technology 2:

During the whole growth period of strawberry, the amount of fertilization per mu is 3000-3500 kg of organic fertilizer (or 450-500 kg of commercial organic fertilizer), 14-16 kg of nitrogen fertilizer, 6-8 kg of phosphate fertilizer, and 8-10 kg of potassium fertilizer. Organic fertilizer was used as base fertilizer, nitrogen and potassium base fertilizer and secondary topdressing, and the ratio of fertilizer application was 3:3:4. All base fertilizers for phosphate fertilizer, chemical fertilizer and farmyard fertilizer (or commercial organic fertilizer) were mixed and applied.

Basal fertilizer is dominated by organic fertilizer with appropriate quantified fertilizer. General Mushi farmyard fertilizer 3000-3500 kg or commodity organic fertilizer 450-500 kg, urea 5-6 kg, 15-20 kg of ammonium phosphate, potassium sulfate 5-6 kg.

Composting is generally divided into two stages, dressing at the flowering stage, applying 9-10 kilograms of urea per mu, and 4-6 kilograms of potassium sulfate; top dressing during berry enlargement, 11-13 kilograms of urea per mu, and 7-8 kilograms of potassium sulfate.
