Strawberry is a perennial herb. Its fruit is soft and juicy, sour and sweet, palatable, beautiful in appearance and rich in aroma. Therefore, it is favored in the domestic and foreign markets and is known as the "fruit Queen". So many farmers grow strawberries, but the leaves of strawberries will turn yellow in the process of growth. So why do the leaves of strawberries turn yellow? How do strawberry leaves turn yellow? How can we keep strawberry leaves from turning yellow? The following small series will give you a detailed introduction to the causes of strawberry leaf yellowing and the correct solutions.
Strawberry leaves turn yellow. Strawberry leaves turn yellow due to the following reasons: 1. The gap between dry and wet is too large. After the plant is not watered for a long time, the leaves wilt first and then turn yellow. In other words, if it is not watered for a long time, it suddenly turns yellow after a large amount of water. Correct approach: Strawberry watering should imitate nature. It's sunny and rainy (don't dry or water). Remember to water moderately. 2. The change of ambient temperature, which is suddenly transferred to the air outlet with air conditioner in the greenhouse, will cause yellowing and leaf loss. The lack of sunlight will affect the photosynthesis of strawberries, reduce leaf evaporation and promote plant circulation disorder. The correct approach: to be placed in a leeward and sunny place for cultivation.
Strawberry leaves yellowing 3. Yellowing and leaf loss caused by lack of trace elements or excessive fertilization. Correct approach: if the light and watering are normal, the yellow leaves are caused by lack of fertilizer. Apply some fermented rice washing water or evenly apply 20 grains of compound fertilizer under the soil near the basin every month. 4. Yellowing and leaf loss caused by metabolism and diseases, but not large-scale leaf loss. Correct approach: if strawberries are planted in a large area, weeds and underground pests should be removed first. It can be sprayed with 1000 times of 50% phoxim emulsion (5-6cm in wet soil layer) to control grubs, mole crickets and ground tigers. If you plant it yourself, remember to trim the remaining leaves regularly or use pesticides reasonably. Experience of strawberry maintenance:
(1) Strawberry is a perennial herb, which needs to absorb a lot of nutrients from the soil. Fertilization is mainly based on base fertilizer, and should be supplemented with nitrogen, phosphorus and potassium quick acting fertilizers to meet the needs of normal plant growth, and fertilizer should be supplemented according to different growth stages.
(2) When planting strawberries, the soil pH is ideally controlled between 5.7-6.5, at least not lower than 5.5 or not higher than 7.5. If the pH is too low, lime materials need to be applied, preferably bitter soil lime or oyster shell powder. The soil has good hydrophobicity. If you want to plant it in the ground, be careful not to use the land where potatoes have been planted before, because strawberries are easy to infect a pathogen on potatoes.
(3) Dry leaves, diseased leaves and thin lateral buds should be removed in time in the growing season, and unnecessary stolons and young plants should also be cleaned in time. When the fruit is ripe in June, pay attention to keeping the berries clean. You can pad kraft paper after the flower to separate the sagging fruit from the soil. In winter, strawberries are in dormant stage. During this period, the soil should be kept moist, and the pots must be changed in the third year of potting.
