Strawberry calcium effect is good
Strawberry over-fertilization can easily introduce excessive salt, which induces calcium deficiency disorders. For strawberry plants that have developed symptoms of calcium deficiency, 0.5% calcium chloride solution is generally used for spraying. For strawberries in large greenhouses with dry coke in large areas, if necessary, they can be diluted with water to dilute the excessive salt concentration in the soil. Conditional use of calcium cyanamide will be better. In the 1960s and the 1970s, calcium cyanamide had been used as a nitrogen fertilizer. It is rich in calcium and can meet the high calcium requirement of strawberry growth. It contains dicyandiamide and can inhibit the nitrification of soil nitrogen and prevent nitrogen. Leaching and controlling the accumulation of nitrate, a harmful component of the product, improves the quality of the strawberries. Due to the toxicity in the period of time after the application of calcium cyanamide, it can only be used as a base fertilizer and cannot be top-dressed. When applied as a foundation, it must be applied 7-10 days before sowing or transplanting. It can be ploughed immediately after appling about 40 kg of the surface of the mu, and watering should be performed when the soil moisture is insufficient. The calcium cyanamide contains nitrogen, which can reduce the amount of nitrogen fertilizer applied, combined with the use of phosphorus and potassium fertilizers. The application of calcium fertilizer in strawberry has the following effects: 1. Increased resistance to pests and diseases can induce strawberry system acquired resistance or system disease resistance, and the main diseases of strawberry are reduced by 20% to 30%. 2. Improve quality After applying calcium fertilizer, the fruit of strawberry is bright red, round, and the sugar content is increased. 3, increase the yield of plants are better than no application of strawberries, the increase rate of 19.1% -28.7%. 4. Pre-mature strawberries are picked and marketed 5-7 days earlier than they were not.
