Coconut bran is a byproduct of coconut shell fiber processing and is a pure natural organic medium. It is mainly made of coconut shells through crushing, washing, desalting and drying. It is acidic with a pH value between 4.40 and 5.90 and a variety of colors, including brown, brown, dark yellow and black. When using coconut bran to grow strawberries in a greenhouse, you need to pay attention to the following key points:
Coconut bran preparation and processing: Choose coconut bran of appropriate specifications to ensure that it has good water retention and air permeability. Before use, the coconut bran needs to be fully soaked and kept moist to better play its role. You can add high-quality commercial organic fertilizer in appropriate amounts to provide the nutrients needed for strawberry growth.
Planting rack and cultivation trough setting: The planting rack should be designed reasonably to ensure that the strawberry plants can get sufficient light and ventilation. The size and shape of the cultivation trough should be adapted to the specifications of the coconut bran for filling and fixing. Pay attention to keeping the cultivation trough clean and hygienic to avoid the breeding of pests and diseases.
Water and fertilizer management: Watering should be done in moderation to keep the coconut coir moist, but avoid waterlogging that may suffocate the roots. Fertilization should follow the principle of small amounts and multiple times, and formula fertilization should be carried out according to the growth needs and nutrient absorption characteristics of strawberries. Pay special attention to the supplementation of trace elements such as calcium, iron, magnesium, and zinc to ensure the healthy growth of strawberries.
Temperature and humidity control: The temperature and humidity in the greenhouse should be precisely controlled according to the growth stage of strawberries. During the budding, flowering, fruit expansion and maturity stages of strawberries, a suitable temperature environment should be provided to ensure the normal growth and development of strawberries. Humidity management is also very important, and excessive humidity should be avoided to prevent the occurrence of diseases.
Pest and disease control: Although soilless cultivation can effectively reduce soil-borne diseases, pest and disease control work still needs to be done well. Physical, biological and chemical methods can be used to comprehensively control pests and diseases and reduce the use of chemical agents. The growth of strawberry plants should be checked regularly to detect and deal with pest and disease problems in a timely manner.
Daily management and harvesting: During the growth period of strawberries, old leaves, diseased leaves and deformed fruits should be removed in time to facilitate ventilation, light transmission and nutrient supply. Thinning of flowers and fruits should be carried out to ensure the quality and yield of strawberry fruits. When the strawberry fruits are ripe, they should be harvested in time and graded, packaged and sold.
In addition, attention should be paid to the reuse of coconut bran. To save costs, coconut bran can be reused for 2 to 3 planting cycles, but the large roots of strawberries from the previous season need to be removed and disinfected with horseradish to avoid the spread of pests and diseases.
