In spring, as the temperature rises, strawberries go from dormant state to growth stage. Strengthening the management of strawberry in spring will lay a solid foundation for high quality and high yield of strawberries this year and high yield and stable production next year. Its main measures are as follows:
First, remove the cold cover
When the average temperature on the spring day stabilizes above 10°C, remove the cover from the strawberry seedlings. Be careful not to tear the branches and flowers of the strawberries so as not to affect the yield of the strawberries. If it is double-covered, it is necessary to remove the upper film first, but it is necessary to do a good job of hardening the seedlings to prevent the temperature difference from being too large and the frostbite seedlings will affect the growth and development of the strawberries.
Second, timely cultivation and fertilization
Cultivation of strawberries in open field, timely cultivating, fertilizing and weeding after spring. Strawberry fertilization is mainly based on compound fertilizer, urea, or dilute human fecal urine, avoiding the use of ammonium nitrate and ammonium sulfate, and generally applying 20 kg of compound fertilizer or 6-7 kg of urea per acre. The fruiting period can be supplemented with foliar fertilizer according to specific conditions.
Third, sparse buds and flowers to mention the temperature
After the budding of the strawberry, the thin buds should be sparse so as to avoid the excessive supply of nutrients caused by too many buds, which will make the strawberry grow weak, small and abnormal. In addition, the fruit thinning work should be done well during the flowering period to make the strawberry fruit uniform in size and consistent in maturity, and to improve the quality of the strawberry and the economic benefits of cultivation. Raising the temperature of the ground can accelerate the growth and development of the strawberry. The method is to cover the surface with a mulch, and it is also possible to lay down the straw and other coverings under the strawberry plant.
IV. Prevention of diseases and diseases
After the fruit grows in the field, the strawberry fruit will make the fruit soft, deteriorate and even rot. Therefore, in the event of spring drought, we must speed the irrigation speed, when the spring is rainy, we must clear the ditch. When a disease occurs, it is necessary to immediately spray 70% of thiophanate-methyl 800-1000 times or 50% of carbendazim 500-fold, and spray 2-3 times, which can effectively suppress the occurrence of diseases.
Cooling Agent, is a general term for all the chemicals that can produce cooling effects and are not strong. The most common Cooling Agent is menthol (especially L-menthol), but it should not be used in large quantities due to its strong odor and strong irritation to the skin, mucous tissue, and eyes. Therefore, many scientists have synthesized and extracted a new generation of cooling agent.
