Strawberry's requirement for fertilizer and water is higher than that of ordinary fruit trees. Therefore, applying sufficient and applying base fertilizer is the key to the high quality and high yield of strawberries.
Organic fertilizers are used as the main base fertilizer, mainly organic fertilizers, and appropriate quantitative fertilizers are applied. From the point of view of the fattening laws of strawberry planting, it is necessary to absorb a large amount of fertilizers, especially phosphorus and potash fertilizers. The decomposition process of organic fertilizers shows that just after release, large amounts of phosphorus and potassium are released, which can meet the growth needs of strawberries. Each mu of fully cooked organic fertilizer 3000 to 3500 kg or commodity organic fertilizer 400 to 450 kg. Simultaneously add 15 to 20 kg of ternary compound fertilizer or 5 to 6 kg of urea, 15 to 20 kg of diammonium phosphate, and 5 to 6 kg of potassium sulfate.
Strawberries supplemented with bio-organic fertilizers should not be re-puppeted in principle. Otherwise, root rot and other root diseases are prone to occur. Therefore, the greenhouse must be disinfected with soil to compensate for the loss of soil-killing beneficial microorganisms. When applying base fertilizer, bio-organic fertilizer is applied. Mu 100 to 150 kg. Bio-organic fertilizer is rich in organic matter and various beneficial microorganisms. It can not only improve the structure and physical and chemical properties of soil, but also provide enough nutrients for crop growth.
