Detailed Explanation of Key Technical Points for Strawberry Water and Fertilizer Management
Strawberry is a very popular fruit, with extremely beautiful berries that look appetizing at first glance; its fruity aroma is also very fresh, and more importantly, it is rich in nutrients and has high nutritional value. Strawberry cultivation is becoming more and more common in our country, but this does not seem to affect its market price and sales. So in the process of strawberry cultivation, how should water and fertilizer management be carried out? This is a very critical step, and today the editor will briefly introduce it to everyone.
1. Water and Fertilizer Management During the Seedling Raising Period
Before planting, strawberries need to go through a period of seedling raising. During this period, the soil of the strawberry sowing field is generally relatively loose field soil rich in organic matter with convenient drainage and irrigation. So the first thing we need to do is apply sufficient base fertilizer, and the base fertilizer for strawberry cultivation is mainly decomposed farmyard manure, about 3,500 kg per mu, followed by 450 kg of organic fertilizer, combined with a small amount of urea, phosphate fertilizer, and potassium fertilizer, spread together. Then after sowing, carry out appropriate micro-irrigation, which can not only maintain soil moisture but also save water resources.
2. Water and Fertilizer Management During the Growth Period
Strawberry is a shallow-rooted plant, but its root system is still relatively well developed, so after transplanting and surviving, we should focus on watering and fertilizing. This is especially true during the two periods before flowering and during the fruit swelling stage. When strawberries have just been transplanted, nitrogen fertilizer is mainly used, combined with phosphate fertilizer, in order to promote the growth of strawberry branches and leaves, and it should be applied together with watering. The pre-flowering fertilizer is generally applied at a rate of 20 jin of nitrogen fertilizer, 10 jin of phosphate fertilizer, and 30 jin of potassium fertilizer per mu. During the fruit swelling period, the fertilization amount is generally 20 jin of nitrogen fertilizer, 20 jin of phosphate fertilizer, and 40 to 50 jin of potassium fertilizer. Of course, potassium fertilizer and phosphate fertilizer can also be replaced by a three-element compound fertilizer, and the amount generally should not exceed 40 jin.
3. Application Methods of Micro-fertilizers
During strawberry growth, many people overlook the use of micro-fertilizers and generally only apply main fertilizers. In fact, micro-fertilizers are also very important in the growth process of strawberries, and the micro-fertilizers needed for strawberry growth generally include calcium fertilizer, magnesium fertilizer, boron fertilizer, zinc fertilizer, iron fertilizer, and so on. Therefore, during its growth process, to ensure that these trace elements are complete, we need to apply additional micro-fertilizers rich in these elements. Examples include superphosphate, borax, monopotassium phosphate, calcium sulfate, manganese sulfate, and so on. We need to mix them according to a certain nutrient composition and ratio, and dilute them into liquid fertilizer for spraying.
4. Micro-irrigation and Fertilization
The growth of strawberries generally has synchronized demand for water and fertilizer, so the fertilization method of micro-irrigation is currently a direction in strawberry cultivation. We need to control the amount of water and fertilizer applied according to the different growth stages of strawberries. Micro-irrigation and fertilization is the method of diluting fertilizer into liquid fertilizer and applying it by sprinkler irrigation. This is more conducive to the absorption of nutrients and the regulation of the soil.
The above is all the content the editor has brought to everyone today about water and fertilizer management techniques for strawberry cultivation, and I hope it can help all friends who grow strawberries. If everyone has better fertilization methods or types of fertilizer, you are welcome to leave a message and recommend them to the editor.
