During the strawberry picking season, I want my own strawberries to be big, sweet and thoughtful, with high quality and yield. However, in the actual strawberry planting process in winter, there will always be several problems such as long stubble time, premature root aging, leaf dormancy, gray mold powdery mildew that cannot be prevented, red spider damage, fruit deformity and so on. Everyone knows that leaves grow by roots, roots depend on leaves, and leaves can be good fruits. Winter root and leaf care is the key to high yield and high quality of strawberries.
The roots are raised by the leaves, the leaves are grown by the roots, and the leaves are good and the fruits are good. During strawberry growth, a large amount of nutrients are produced by the leaves, and the taste and yield of the fruit are determined by the leaves. Therefore, during the flowering and fruiting period of strawberries, we should not only pay attention to the maintenance of the root system, but also pay attention to the protection of leaves.
Winter strawberries often show symptoms such as dull leaf color, slow growth, and decreased disease resistance, which are often related to low temperatures, nutritional imbalances, and insufficient light. The temperature in the strawberry shed is lower than 15, and the ability of the root system to absorb water and fertilizer decreasesWhen the night temperature is lower than 5, the strawberry leaves are dormant. The root system is premature at low temperature, the leaves are dormant, and the nutrient supply is unbalanced. Therefore, it is necessary to ensure reasonable light and temperature, and enhance the photosynthesis of plants by artificial light and adjusting the temperature of the greenhouse.
Tips for raising strawberry leaves in winter
Strawberries carry out photosynthesis through leaves, produce nutrients and sugar for the growth of various organs, strawberries need a lot of nutrients during the fruit expansion period, which is also the key to strawberry expansion and sweetening, so do not blindly split leaves in the flower and fruit period. Regarding the number of leaves left, some people always have this misunderstanding: the leaves grow more, and they compete with the fruit for nutrients. Under normal circumstances, it is recommended to leave one leaf for one fruit, and it is recommended to leave 6-12 functional leaves for the flowering and fruiting stage. The specific number of leaves to stay, depending on the overall growth of the seedlings, if the planting is dense, then a little less, if the amount of fruit is large, it is appropriate to leave more.
Key points of low-temperature strawberry root management
The root of strawberry is an important organ for the absorption and transmission of water, nutrients and endogenous hormone synthesis, and plays an important role in the high yield of strawberry.
1.Raise the ground temperature. In winter, special attention should be paid to prevent the occurrence of frost damage to the roots. By adding insulation facilities, it is possible to avoid damage to the roots caused by sudden temperature drops. When extreme weather comes, pouring water from deep wells can also raise ground temperatures.
2.Low temperature strawberry flowering and fruiting period can not deliberately create a dry environment, watering is not recommended watering. Flushing fertilizer should be balanced nutrition, with low-temperature root-raising deep-sea fish protein puree, 3 20 nutrient balance fertilizer, small molecule easy to absorb chelated calcium and magnesium fertilizer, etc., which are used in rotation at different times.
3.Grow the roots with fungi. Increasing the mineral source of potassium fulvic acid and Bacillus subtilis to condition the soil and enrich the soil flora can not only activate the soil and increase soil permeability, but also effectively curb harmful bacteria and achieve the disease prevention effect of strawberry roots.
4.Pay attention to the concentration of fertilization pesticides.
Excessive fertilization concentration may cause fertilizer damage, and it is recommended to supplement a small amount and multiple times during the low temperature period to avoid burning the roots with thick fertilizer. Pesticide concentration is too high or improper spraying methods can also cause pesticide damage, so be sure to consult a dispenser or technician when using fertilizers and medicines.
The high yield of strawberries is inseparable from root to leaf care. Root nourishment and leaf protection are mutually reinforcing and complementary. Healthy leaves ensure adequate photosynthetic products, while a strong root system guarantees efficient nutrient and water uptake. In winter, special attention should be paid to temperature management and water and fertilizer supply, and timely response to common strawberry symptoms, which are the key factors for high strawberry yield in winter.
