Fertilization method of Strawberry in Winter

Strawberry taste sweet and sour, deeply loved by everyone, now many businesses are also actively cultivating winter strawberry, strawberry itself summer fruit, the cost of winter cultivation is higher, and its price in winter is also relatively high. So how are strawberries fertilized in winter? Let's get to know it with the editor.

1. Fattening

Fertilization at seedling stage should be based on compost, livestock fertilizer, cake fertilizer and other organic fertilizer, adding microbial agents to improve the utilization rate of organic fertilizer, and then applying chemical fertilizers such as calcium superphosphate and potassium sulfate. In order to differentiate the flower buds of the seedlings, an appropriate amount of base fertilizer can be applied during pseudo-planting, and nitrogen fertilizer can be applied once in the middle of pseudo-planting, with 5-10 kg of urea per mu or 150-250 kg of mature human feces.

2. Base fertilizer

After planting, strawberries begin to blossom and set fruit. Because of its long growth period, base fertilizer should be used before planting. 5000 kg of farm manure per mu, 6-8 kg of microorganisms should be added and mixed to alleviate the obstacles of soil continuous cropping and improve the utilization rate of organic fertilizer. If the acid soil is applied another 50 kg per mu, the soil can be deeply turned over after application. In the first year of planting in autumn and every summer and autumn, 2000-3000 kg of compost, 50-100kg of cake fertilizer and 7-10kg of compound fertilizer can be applied per mu.

3. Reasonable topdressing

The specific application amount should be determined by the amount of fruit harvest, more fruit harvest, less fruit harvest and less fertilization. before flowering, 10-15 kg of compound fertilizer and 200-300 kg of mature human feces should be applied per mu. In the future, topdressing should be applied separately when the fruit is enlarged and harvested, and topdressing is needed for 4-5 times in the whole growth period to meet the needs of plant growth and fruit development.

4. Foliar fertilizer

After the strawberry fruit is set, foliar fertilizer should be sprayed for 2-3 times 0.2% KH 2PO 4 and 0.5% urea. In addition, in order to improve the taste and quality of the fruit, it is necessary to apply microbial agent and dilute 200 to 300 times solution for foliar spraying. In addition, the lack of calcium will also lead to fruit decay, so we should pay attention to the supply of soluble calcium, increase the application of organic fertilizer, increase the content of soil organic matter, and control the application of nitrogen fertilizer.
