Detailed Explanation of Key Points in Cream Strawberry Cultivation Techniques
Strawberries have a sweet and sour taste and are deeply loved by people. In recent years, China has introduced a new strawberry variety from abroad called cream strawberry, also known as Caoji. It was bred by hybridizing two varieties. Its fruit shape is elegant, the color is bright and glossy, the juice is sweet and rich, and the flesh is soft. So how should cream strawberries be planted? Let's take a look together.
1. Seedling selection
Seedling selection is the first step in growing cream strawberries well. Generally, strong seedlings with more than three leaves should be selected for cultivation. The specific operation is to select robust mother plants in spring, remove old, weak, and diseased leaves, and then transplant and raise seedlings at a row spacing of 1 m x 0.8 m. During high temperatures in summer, shading is needed for the seedlings to prevent strong light from scorching them or causing water loss, and measures to promote flower bud formation should also be taken.
2. Field planting
One month before field planting, the strawberry field needs to be turned and sunned, and an appropriate amount of insecticide can be added to eliminate underground pests. Cream strawberry field planting is generally carried out in October. On the day of field planting, choose a cloudy day or a sunny afternoon, and try to avoid the high-temperature period. Before lifting the seedlings, water the nursery thoroughly. When lifting the seedlings, try to keep as much soil as possible and damage the roots as little as possible. When planting, bury them shallowly, and do not bury the crown. Make sure that after watering and settling, the heart leaves are still above the soil surface. After field planting, provide shade treatment to prevent high-temperature scorching.
3. Field management
After field planting, pay attention to temperature and diseases. When the temperature is below 16°C, greenhouse covering should be carried out, and try to choose greenhouse film with good light transmittance to meet its light requirements. In addition, pay attention to ventilation to avoid excessive growth or disease outbreaks caused by high temperatures. When loosening the soil after field planting, pay attention to applying sufficient base fertilizer. The base fertilizer is generally a mixed application of fully decomposed farmyard manure and compound fertilizer. The amount of farmyard manure is about 4000 kg per mu, and the compound fertilizer is about 50 kg per mu. During the growth period, fertilization should be carried out multiple times to ensure yield. The fertilizers applied at each growth stage are different, so pay attention to this. During the young fruit swelling stage, fruit thinning is needed, removing diseased, insect-damaged, and deformed fruits, and concentrating nutrients to ensure the growth of high-quality fruit.
4. Pests and diseases
Once pests and diseases occur in strawberries, they will definitely have a huge impact on yield and quality, so the principle of giving priority to prevention and comprehensive control must be adhered to. The seedling stage and field planting period are periods of high incidence of anthracnose. It is recommended to disinfect the soil, and fungicides such as Baike and anthracnose Fumei can be selected for control.. After covering the greenhouse, it is recommended to fumigate the greenhouse with sulfur at night to prevent the occurrence of powdery mildew. If powdery mildew has already occurred, Amistar, Cuibei, etc. can be used for treatment. Pests mainly include aphids and mites such as red spiders. Aphids can be controlled with insecticides such as pirimicarb and imidacloprid, and mites can be controlled with acaricides.
