What fertilizer is used to grow strawberries? What are the demand for elements in strawberries?

Strawberry is a kind of popular fruit. It is widely planted in China, but it develops well in fertile, loose neutral or slightly acidic soil. Strawberry has good growth, high flowering and fruiting rate, and good fruit storage tolerance. Water and fertilizer management and field planting in the growth process are very important. This article talks with you about how to manage strawberries.

How to manage strawberries to grow well

1. Seedling selection

Strawberries suitable for local soil environment, climate environment and market demand can save a lot of unnecessary manpower and material resources in the planting management stage. At present, there are many strawberry varieties with a wide range of planting areas in China, such as Ningyu, Hongjiao, Zhangji, Hongjiao, Fengxiang, etc. For the land with relatively more diseases, it is appropriate to select varieties with better disease resistance.

2. land preparation

Strawberry diseases, including root rot, stem base disease, leaf blight, bacterial wilt, virus disease, etc. Some of the diseases come from the spread of soil. It is suggested that rotten farm manure and high-quality organic fertilizer should be used for fertilization in the process of soil preparation, and microbial mycorrhizal fertilizer for root rot and resistance to soil-borne diseases should be added for spreading or root irrigation after planting, which can prevent part of the disease in the growth period.

It is better to plant strawberries after soil preparation to draw high furrows. On the one hand, it can highlight the growth of plants and maintain good ventilation and light transmittance. On the other hand, it can also facilitate management and prevent the possibility of diseases and insect pests caused by excessive contact with shaded places.

3. Irrigation

Strawberry root shallow, but relatively large leaf transpiration is more vigorous. Although strawberry likes water, it is not resistant to waterlogging, and the amount of irrigation must be well controlled in planting management. If conditions permit, drip irrigation and watering are better. If conditions permit, watering must follow the water requirement rule of strawberry growth period. In the early stage, frequent watering with small water is better. In the fruit swelling period, the irrigation amount can be appropriately increased, but it should be free of water accumulation and the soil humidity should not exceed 85%.

4. Fertilization

According to the growth stage of strawberry, urea and potassium dihydrogen phosphate are selected for top dressing in the early growth stage. Before and after flowering, foliar fertilizer potassium dihydrogen phosphate and flower-promoting and fruit-preserving swelling can be used in combination to improve the flowering and fruit setting rate. Spraying potassium dihydrogen phosphate foliar fertilizer 2-3 times in the whole growth cycle can well resist diseases and strengthen seedlings and supplement the rapid demand of trace elements after fruiting and fruit swelling, if necessary, calcium, magnesium, boron, zinc or twelve elements can be selected for supplementation to improve the quality and storage resistance of the fruit.

5. Field management

Including the appropriate control, the timely prevention and control of pests, it should be noted that many diseases can develop and spread through the prevalence of pests, and have a serious impact on the yield of strawberries. In addition, the use of fungicides and insecticides to prevent and control diseases and insect pests must take into account environmental factors, greenhouse strawberry planting, the use of insecticide fertilizer and nutritional disease-resistant foliar fertilizer for spraying must be very good control of indoor temperature, humidity, ventilation and light transmittance. Robust plants are the basis for more flowering, more fruiting, good quality and storage tolerance.
