After good strawberry seedlings were transplanted to the field, dead seedlings appeared on some plots. After investigation, it was known that the cause of dead seedlings was the serious shortage of potassium in transplanted field soil, which caused the petiole of the leaves to burn into dark brown, followed by dry and necrotic. Therefore, Yu Hongzhang, a senior agronomist, reminded us that in the strawberry production process, we must balance the application of basal fertilization in accordance with fertility requirements. Strawberry roots are shallow, and it is necessary to have loose and loose soil before they are conducive to rooting. Strawberries should be finely soil-prepared before they are transplanted, and the soil should be ploughed and soil loosened to make sure the roots are tied down. According to the determination of the agricultural scientific research department, the ratio of strawberry's demand for large amounts of nitrogen, phosphorus, and potassium is 1:1.26:0.74. Yu Hongzhang believes that when using basal fertilizer, organic fertilizer should be used as the main ingredient and multi-element compound fertilizer should be applied. Decomposing farm manure 4000-5000 kilograms, or 150-200 kilograms of organic commercial organic fertilizer, 50 kilograms of N, P and K compound fertilizers, and 10-15 kilograms of potassium-sulphate compound fertilizer for soils lacking potassium. Potassium is more sensitive. Increasing organic and potassium fertilizers can promote strawberry ripening for 2-3 days, effectively increase sugar content and improve quality.

Transplanting Strawberry Attention to Balanced Fertilization
It is at the moment when strawberries are transplanted that there are many dead seedlings in Hubei. Experts reminded that we must attach great importance to this phenomenon, so as to avoid shortage of seedlings, affect production and quality.
