Organic strawberries are extremely soft in storage and have a high rot rate. At present, the main natural cryogenic storage or rapid freezing to extend the storage period and reduce the loss of decay.
Organic strawberry soil preparation and variety
Strawberry farms should choose sandy or loamy soil with flat ground, slightly high topography, deep loose soil, fertile, well-ventilated and well ventilated water. The garden can be sprayed with 50% phoxim EC 1000 times to control lice, earthworms, and tigers. Varieties should choose golden stars, carbon rich growth potential, high fruit set rate, shade-resistant, cold-resistant, resistant to powdery mildew, dormancy period short of fine varieties.
Organic strawberry timely planting shed
In order to fight for the morning market, strawberries should be transplanted in the greenhouse in early September. To transplant with the seedlings. Each row is planted with 2 rows, with a 25 cm spacing and a 20 cm hole spacing, and about 12,000 plants per acre. Plant water in a timely manner and bury the exposed roots in the soil. Shedding time is usually around mid-November.
Organic strawberry temperature and humidity management
The optimum temperature for the development of strawberry fruit is 18-25°C. To reach this temperature in winter and early spring, the middle shed can be covered with a plastic film in the greenhouse. During the day, the indoor temperature of the shed is kept at 28-30°C, and it is maintained at 5°C or more during the night. . When there is a high temperature above 30°C, it must be ventilated and cooled. When the humidity in the booth exceeds 70%, timely ventilation is required.
Fertilizer
Greenhouse strawberries have a long period of time. To prevent defertilization and premature aging, it is possible to use Bibo's large quantities of water-soluble fertilizers and sprays. Water immediately after planting. In the early stages of flowering and berry growth, irrigation was performed once. If drought occurs, irrigation should be done 5-7 days. When it is rainy in autumn, it should be drained in time. A drainage ditch should be built around the strawberry garden so that the water in the shed can be drained.
Tillage soil and picking leaves and fruit
The cultivating loose soil is conducive to the decomposition of organic matter. Remove old leaves and weak fruits, reduce nutrient consumption, and help strawberry growth and berry development.
Comprehensive control of pests
The strawberry pests and diseases in greenhouses are mainly controlled by agriculture, supplemented by chemical control. Diseases and insect pests can be prevented through the selection of disease-resistant varieties, cultivation of virus-free strong seedlings, high-ridge planting, mulching, rational rotation, soil cleaning, drought avoidance, and high humidity. If diseases are found, care should be taken not to use herbs before and after flowering so as not to affect pollination and increase malformed fruit. Efficient, low-toxic, low-residue pesticides should be selected and pesticide dosages and safety intervals should be strictly controlled.
Timely harvest
Strawberry picking is generally 8-10 am or 4-6 pm. Generally do not pick fruit and hot fruit in order to avoid deterioration. When harvesting, take it gently and do not damage it.
