To keep strawberries delicious with water and fertilizer management

Using soil testing, formulating fertilization before planting through soil testing to understand the soil fertility status, and according to the characteristics of strawberry fertilizer, to develop a balanced fertilization program for the whole strawberry growth period, that is, soil testing formula balanced fertilization, a reasonable Balance of nitrogen and phosphorus , Potassium three elements of fertilizer, with trace elements in fertilizer, determine the base fertilizer, top dressing ratio.

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 ~ 3500 kg or commodity organic fertilizer 400 ~ 450 kg. At the same time, add ternary compound fertilizer 15 to 20 kg or urea 5 to 6 kg, 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 100~150 kg. Bio-organic fertilizer is rich in organic matter and various beneficial microorganisms. It can not only improve soil structure and physical and chemical properties, but also provide enough nutrients for crop growth. It contains a variety of beneficial micro-organisms that can be metabolized to produce various enzymes and organic acids. Can promote the difficult nutrients in the soil, enhance the effectiveness and easy absorption of soil nutrients. The beneficial micro-organisms can also produce a variety of vitamins and growth stimulants during the growth process, which can effectively promote root growth and development.

The application of base fertilizer should be applied when the soil is plowing, and the depth should be controlled at about 20 cm to ensure that the fertilizer is evenly distributed, and debris such as hard clay blocks, stones, weeds, and shredded membranes should be removed.
