1.Irrigation/spaying: Dilute the fertilizer with 500-800 times water before irrigation/spraying. Apply 200-400kg/ha.
2.Drop-irrigation: Dilute the fertilizer with 800-1000 times water before irrigation. Irrigate 3-5 times. Apply 200-400kg/ha.
3.As base fertilizer, apply 300-600kg/ha with appropriate amount compound fertilizer 5-7 days before crops transplanting or 5-7 days after harvest.
Apply bio fulvic acid round granule with mineral fertilizer for better effect.
1. Kinds of nutrition and timely supply.it is rich in Organic matter ,amino acids, proteins, nucleic acids, betaine and bio-fulvic acid, while it contains inorganic (N+P2O5+K2O) nutrients and calcium, magnesium, sulfur, iron, zinc, manganese, copper, molybdenum, boron and other trace elements, which satisfy the requirements of crops. Nutritional balance improve crop growth, buds fatness, roots strength, seeding vigorous, well leaf photosynthesis, lodging-resistance, high fruit set rate, and make the crops early bring forward market and extend the harvest picking.
2. Improvement of nutrients balance in the soil. Application of fertilizers can promote the formation of aggregate structure and improve the capacity of soil permeability, water, fertilizer and drainage by the gelation, adsorption and mineralization, and coordinate the four factors of supplement of water, fertilizer, gas and heat in the arable land, so that to achieve sustainable use of soil.
