As one of the most popular fruits, strawberry is widely cultivated all over the country for its well-known flavor and nutritional value.
In order to ensure that after each crop of strawberries is harvested, the number of subsequent crops can keep up and the quality of strawberries does not decline, it is very necessary to restore the nutrition of strawberries after harvest. After strawberry harvest nutrition recovery, need to do the following:

　　1. to do a good job of light and heat management
Strawberry growth temperature at 15-25 degrees Celsius, below 5 degrees Celsius to stop growth, flowering stage below 0 degrees Celsius, will affect the normal development of pollination and seed, easy to produce deformed fruit, it is recommended to control the greenhouse strawberry postharvest temperature between 5-17 degrees Celsius, is conducive to the flower bud differentiation of strawberry.
Strawberry in flower bud differentiation and fruit expansion stage, the water demand is larger. The soil water content should be maintained at about 60% during the flower bud differentiation period, and more than 80% during the fruit expansion period. Soil water or lack of water are likely to affect the quality of pollen, resulting in poor fertilization, the same will affect the expansion of fruit stage of dry matter accumulation.
Strawberry is a light-tolerant crop, and different varieties of strawberries have different requirements for light hours. Generally speaking, the favorable sunshine hours during the flower bud differentiation period are only 12 hours, while the flower and fruit merge period requires 12-15 hours of sunshine hours.

　　2. plant growth management
In the whole growth process of strawberries, strawberries should be timely to remove old leaves, diseased leaves, prostrate stems and so on, so as to avoid the vigorous growth of strawberries and consume their own nutrients. Before flowering and after fruit picking, redundant buds should be removed in time. Large fruits retain the first and second order buds, and intermediate fruits retain the third order buds. Avoid nutrient dispersion, affecting fruit development.

　　3. to do a good job of strawberry postharvest nutrition recovery
Ruifeng Guomei Aim at Root Wang
As a flower and fruit crop, strawberries can be planted at one time and picked in multiple rounds. Strawberry will consume a lot of nutrients every time it blooms and bears fruit, so it is necessary to make timely nutritional supplements after harvest to quickly promote the recovery of plant nutrition. After each harvest, "Ruifeng Guomei aiming at root prosperity" can be applied once to promote rooting and water and fertilizer absorption, timely supplement plant nutrition, increase the number of picking rounds, and improve the economic value of strawberries.
