What are the key points for spring management of strawberries?
Strawberries are a relatively popular fruit on the market, and their price is also relatively high, so more and more people are growing them. In spring, as temperatures keep rising, strawberries will grow better and better. At this time, if you want strawberries to grow well, the first thing to do is strengthen management. So how should strawberries be managed in spring? Let's learn about it together with the editor.
1. Clear away mulch
In early spring, temperatures are relatively low. At this time, for the early spring growth of strawberries, straw is often spread in the field to keep them warm and prevent freezing. When spring temperatures stabilize above 10 degrees, the mulch needs to be removed in time. At the same time, be careful not to break the strawberry branches, leaves, flowers, or fruits, so as not to affect yield and quality. If it is double-layer mulch, then the upper film should be uncovered first. At the same time, also pay attention to doing the hardening-off work well to prevent the seedlings from being frostbitten due to too large a temperature difference, which would have a certain impact on later growth and development.
2. Intertillage and fertilization
If strawberries are cultivated in open fields, then after spring it is essential to carry out intertillage, weeding, and fertilization in time, so as to break up soil compaction, promote well-developed roots, and lay a solid foundation for high yield. Fertilization should mainly be compound fertilizer, urea, or human and animal manure. At the same time, avoid applying fertilizers such as ammonium nitrate and ammonium sulfate, because they will produce a large amount of ammonia gas when decomposing, and strawberries are creeping-stem crops, making it very easy for leaves and fruits to be burned by ammonia gas, affecting yield and quality.
3. Thinning flowers and buds
After strawberries bud, first thin out the weak buds and keep the robust buds. The reason for doing this is to avoid insufficient nutrient supply to strawberries caused by too many buds, which makes strawberry growth weak and relatively increases small fruits and deformed fruits. In addition, during the full flowering period of strawberries, also do a good job of thinning flowers and fruits, so that the fruit size is uniform and the ripening period is consistent, effectively improving the variety and benefits of strawberries. In addition, covering the bed surface with plastic film to increase soil temperature can effectively accelerate the growth and development of strawberries.
4. Prevent diseases
During the fruit growth period, if heavy rain causes waterlogging in the field, and if drainage is not carried out in time, then the fruit will become soft, deteriorate, and even rot. Therefore, in early spring, the drainage ditches should be cleared, and during the rainy spring, drainage should be carried out in time to reduce waterlogging. When disease damage occurs, immediately spray targeted agents and Xin Gao Zhi Mo for prevention and control, spraying once every week, continuously spraying 2-3 chi, to thoroughly prevent and control the disease.
