In recent years, the number of farmers growing strawberries on the outskirts of cities has increased year by year. However, how to make strawberries both high in yield and early in quality, and there are still many planting techniques that need to be improved. Strawberry has very strict requirements on the external environment. It can grow indefinitely when conditions are right, and it can sleep quickly when conditions are unfavorable. If the soil is arid and infertile, the temperature is too low, the seedlings are thin, or the growth is too prosperous, the flower buds are difficult to form or are delayed to affect the ripening period, yield and quality. Only by optimizing the environment and cultivation methods can we promote the early maturity, high yield and quality of strawberries.

First of all, we must apply basal fertilizer to see Miao fertilizer. In general, per acre of base fertilizer to be applied to the farmyard fertilizer 4000 kg or 100 kg of bio-organic compound fertilizer, or high content of inorganic compound fertilizer 20-25 kg. The better growing seedlings generally only follow the phosphorus and potassium fertilizers, spraying 0.2% potassium dihydrogen phosphate 2-3 times. Poor growth of the seedlings, the results of the prosperous period to apply or compound fertilizer 15-20 kg or 10 kg of urea. At the same time, promote the use of Hui Man Fung active liquid fertilizer, 100 ml per mu spray 50 kg of fresh water 2-3 times. If you follow the application of clear water, one must prevent pollution of the environment, and the other must prevent the fragility of fresh fruit.

Second, we must adjust the humidity and control the humidity to break the dormancy. The optimal temperature for strawberry flowering is 10-20°C. If the temperature is lower than 10°C or it is higher than 35°C at noon on the sunny day, infertility will be bad and abnormal fruit will be formed. The shelf temperature below 35 °C is the critical temperature for dormancy. The plants were frozen at -1°C and the pistil suffered. Strawberries are more resistant to waterlogging, and the most suitable is 60-70% relative humidity, that is, soil water content is 80% of the water holding capacity. To this end, one should implement the three-film coverage, that is, mulch film, greenhouse film, and then covered with a small shed film. The second is when the high temperature, sunny days to open the waist membrane ventilation, open the film on both sides of the shed film ventilation. Third, in the continuous high temperature and drought, the use of small gutter irrigation for wet management, so that the strawberry in the normal temperature and humidity conditions as early as possible flower bud differentiation.

Third, to assist pollination, control the fruit and control the fruit. Strawberry mostly self-pollination, but poor infertility will produce deformed fruit or small fruit with poor maturity. In order to achieve fruit quality, we must conduct artificial pollination in the flowering period from 10 am to 3 pm every day. The second is to put a box of bees to assist in pollination in each greenhouse. Third, to control a certain amount of results, generally only about 20 fruit per plant, redundant young buds, small fruit should often be reconciled. The fourth is to control the ramets, leaving only 2-3 new-breeding seedlings per plant.

Fourth, we must often pick old leaves to prevent pests and diseases. In the process of strawberry growth, leaves with old and disabled diseases and pests occur at any time. Common diseases include viral diseases, gray mold, leaf spot disease, and powdery mildew. Insect pests include aphids and red spiders. Prevention methods, first, control the temperature and humidity and seedlings grow. The second is that the leaves of pests and diseases are removed at any time. Third, chemical control of pests and insect pests can be controlled by the use of lime sulfur, worms, and quick-acting sulphur. Diseases can be used to prevent and treat pesticides such as polyoxo-pyrazine, general K crop bactericidal repair fluid, and Shile.
