Strawberry is perennial herbaceous plant, belongs to berry type crop, and has the top yield in the production of small berries in the world. Strawberry is also an important economic crop in China, and according to statistics of food and agricultural organizations in the United nations, the seeding area of strawberry in 2016, 13.0 ten thousand hectares in China, accounts for 42% of the seeding area of strawberry in the world; the total yield of strawberry is 342 ten thousand tons, which accounts for 61 percent of the world total yield. Therefore, strawberry cultivation plays a very important role in the cultivation of Chinese cash crops.
There are many problems in the strawberry production process. In the seedling stage, the common open-field seedling raising mode is unreasonable in nutrient input, the seedlings are slowly revived after transplanting, the death rate is high, the blossoming and fruiting are late, and the phenomena that the daily management of the ground-planting seedling raising is time-consuming and labor-consuming are prominent. The nutrient input proportion, the input amount and the input period after the transplanting and the field planting do not accord with the fertilizer requirement rule of the strawberries, and the controlled release fertilizer matrix seedling culture can realize the fertilizer transplanting of seedlings on the basis of reducing the nutrient input amount, so as to bloom and bear fruits in advance; after transplanting, the efficient utilization of water and fertilizer can be realized based on the nutrient regulation and control of water and fertilizer integration.
In addition, in the existing strawberry planting technology, the strawberry seedling production is mostly carried out in an open field seedling raising mode, so that the problems of slow seedling recovery, high death rate and the like easily occur, the phenomenon of unreasonable nutrient input in the strawberry seedling raising process is serious, and the problems of large nutrient input quantity and large nutrient input period exist. Nutrients in a matrix are easy to lose in the existing strawberry cultivation process, so that strawberry plants are short and small, and the yield of the strawberries is low.
Therefore, there is a need in the art for a method for increasing the nutrient content of strawberry substrate, which can strictly control the nutrient requirement and supply of the culture substrate for strawberry seedlings according to the growth process of the strawberry seedlings, thereby greatly reducing the fertilizer input amount, increasing the fertilizer utilization rate, and providing good nutrient guarantee for the growth of strawberries.

The straw biomass charcoal has light weight, high porosity and strong adsorbability, ensures good substrate permeability, and can help strawberry seedlings to adsorb moisture, so that the planted leaves are thick and healthy. The straw biomass charcoal is rich in surface functional groups (hydroxyl, carboxyl and the like), so that the conversion of water-soluble organic carbon in the material to humus is promoted, and the humification degree of the matrix is improved; and moreover, due to the high conductivity and rich water-soluble nitrogen and phosphorus of the straw biomass charcoal, the nutrient content of the strawberry matrix can be increased by adding the straw biomass charcoal in a proper proportion.
